SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2026-09-10\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

SUMMARY:Estonian HF Cup (ES LL KV)
DESCRIPTION:Sponsor: ERAU\nModes: CW\, SSB\nBands: 80m\nBand note: CW below
  3600 kHz and SSB above it\; 3530-3560 kHz and 3600-3650 kHz are recommend
 ed.\nDuration: 59m\nExchange: RS(T) and a continuous serial number from 00
 1.\nEligibility: Entry limited to ES. K stations may be worked but cannot 
 submit an entry.\nNote: SPONSOR-ANCHORED LOCAL TIME\, and ERAU's own calen
 dar proves the reading: 10:00-10:59 Estonian time is 08:00-08:59 UTC in wi
 nter (EET) and 07:00-07:59 in summer (EEST)\, which is exactly the split E
 RAU prints across the nine stages. The rules give no date rule at all -- 4
 .2 defers to the calendar plan -- so the dates are manual and taken from E
 RAU's published 2026 calendar. Eight of the nine are the first Saturday of
  their month\; February's is the second. The log deadline is 'the Thursday
  of the following week'\, which is not a fixed number of days from the end
  of each stage\, so it is recorded here rather than as log_deadline_days. 
 Stages 4.3 also splits each hour into four periods\; that is a scoring dev
 ice inside one continuous hour.\nRules: https://www.erau.ee/images/LL/ES%2

 e contest free.\nDuration: 26h\nExchange: A contest-specific exchange\; ph
 one and CW on one band count as separate bands and a station may be worked
  once per band per mode.\nLogs due: 2026-09-11\nNote: Two legs a year off 
 ONE record\, because both share a start and end offset -- 0800 UTC Saturda
 y to 1000 UTC Sunday -- and differ only in which weekend they anchor to. S
 ARL states both readings itself\, weekend AND date\, and both agree for 20
 26. log_deadline_days is 5\, which is the right DAY and not the right hour
 : SARL states 'by 21:59 UTC on Friday'\, and the contest ends at 10:00 UTC
  on the Sunday five days before\, so the engine's derived log_due lands at
  17:00 rather than 21:59. The day is exact in every year because both ends
  are tied to the same Sunday. The five hours are recorded here rather than
  papered over.\nRules: https://mysarl.org.za/wp-content/uploads/2025/11/20

 cannot submit an entry.\nLogs due: 2026-09-20\nNote: IT FALLS ON THE SAME 
 WEEKEND AS RSGB'S\, AND THAT IS NOT A COINCIDENCE. Both societies run thei
 r leg of the IARU Region 1 Field Day: RSGB's National Field Day is the fir
 st Saturday of June and IRTS's CW Field Day is the first full weekend\, an
 d the same pairing repeats in September. They are separate contests with s
 eparate rules\, separate logs and separate results -- which is why both ar
 e here rather than one.\n\nThe pairing also settles what the IARU Region 1
  Field Day IS: a framework each member society runs its own contest inside
 \, not a contest IARU publishes rules for. DARC lists it on their calendar
  and says it is IARU's\; UBA lists it too\; IARU Region 1's own site publi
 shes rules for the HF Championship and nothing else. Nobody claims it\, so
  there is nothing to encode under IARU's name.\n\nENTRY IS EI ONLY AND POR
 TABLE ONLY: 'Any individual or group operating in EI complying with Rule 3
 .6 of the General Rules and operating portable on a site'. Stations elsewh
 ere may be worked but cannot enter.\n\nTwo differences from the CW field d
 ay\, both IRTS's own and both matching RSGB's pair exactly: it starts at 1
 300 rather than 1500\, and it drops 160 m.\nRules: https://www.irts.ie/cgi

DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: SSB\nBands: 80m\nBand n
 ote: 3600-3775 kHz.\nDuration: 1h 30m\nExchange: RS(T) plus a serial numbe
 r starting at 1 and incrementing by 1.\nLogs due: 2026-09-10\nNote: THE CL
 OCK MOVES IN NOVEMBER AND THE RECORD SAYS SO PER DATE. September and Octob
 er run 1900-2030 UTC\; November runs 2000-2130. Every leg of this series s
 its on one side or the other of that change\, so a single stored time woul
 d put two of the three runnings on the calendar an hour wrong.\n\nThis is 
 the first use of PER-DATE TIMES in a manual rule\, a schema question NEEDS
 _A_HUMAN had been carrying since the REP FT4 series hit the same wall. The
  alternative was one record per clock time -- six records for a nine-leg s
 eries the sponsor treats as one -- or one record per leg\, which is nine. 
 Splitting by MODE is the split a reader actually wants\, because the mode 
 filter is what they reach for\, and per-date times are what make that spli
 t possible without lying about an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES D
 ATES AND NO RULE for this series. The legs fall on Mondays\, Wednesdays an
 d Thursdays with no discernible ordinal\, which is exactly the shape an or
 dinal must not be fitted to.\n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -
 - RSGB states it outright\, which is worth noting beside the AFS and Club 
 Calls contests where entry really is UK&CD only.\nRules: https://www.rsgbc

 on Tuesday UTC -- and those are different dates whenever the 1st falls on 
 a Tuesday (Sep and Dec 2026). SPONSOR-ANCHORED LOCAL TIME: ARS publishes n
 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n
 ot\, is the one place the sponsor's own table is inconsistent.\nRules: htt

SUMMARY:DARC CW-Ausbildungscontest (unverified)
DESCRIPTION:Sponsor: DARC\nModes: CW\nBands: not yet read off the sponsor's
  own rules\nDuration: 59m\nExchange: not recorded yet — see the sponsor'
 s rules below\nNote: IT COMPLETES A PATTERN DARC DESCRIBES BUT DOES NOT SP
 ELL OUT. Their three short contests take one month of each quarter in turn
 \, all on a Tuesday evening: the RTTY-Kurzcontest in months 1/4/7/10\, the
  FT4 Contest in 2/5/8/11\, and this one in 3/6/9/12. All four of DARC's pu
 blished dates are the SECOND TUESDAY of those months. That is what 'reiht 
 sich vom Termin her in die anderen ... ein' means\, and the arithmetic con
 firms it rather than assuming it.\n\nVERIFIED FALSE because the page that 
 describes the series is prose about teaching CW rather than an Ausschreibu
 ng: no bands\, no exchange\, no deadline. BANDS ARE UNRECORDED\, so every 
 band filter excludes this record.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not 
 stated on the page that describes the series. That sentence sits here rath
 er than in bands_note\, because bands_note is for a sponsor's own wording 
 ABOUT a band list and must never stand in for one -- a test enforces it\, 
 and it caught this.\nUNVERIFIED: these dates have not yet been checked aga
 inst the sponsor's own published rules. Confirm before you rely on them.\n

 ximum.\nDuration: 1h 30m\nExchange: RS(T) plus a serial number starting at
  1 and incrementing by 1.\nLogs due: 2026-09-19\nNote: THE CLOCK MOVES IN 
 NOVEMBER AND THE RECORD SAYS SO PER DATE. September and October run 1900-2
 030 UTC\; November runs 2000-2130. Every leg of this series sits on one si
 de or the other of that change\, so a single stored time would put two of 
 the three runnings on the calendar an hour wrong.\n\nThis is the first use
  of PER-DATE TIMES in a manual rule\, a schema question NEEDS_A_HUMAN had 
 been carrying since the REP FT4 series hit the same wall. The alternative 
 was one record per clock time -- six records for a nine-leg series the spo
 nsor treats as one -- or one record per leg\, which is nine. Splitting by 
 MODE is the split a reader actually wants\, because the mode filter is wha
 t they reach for\, and per-date times are what make that split possible wi
 thout lying about an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES DATES AND NO R
 ULE for this series. The legs fall on Mondays\, Wednesdays and Thursdays w
 ith no discernible ordinal\, which is exactly the shape an ordinal must no
 t be fitted to.\n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -- RSGB states
  it outright\, which is worth noting beside the AFS and Club Calls contest
 s where entry really is UK&CD only.\nRules: https://www.rsgbcc.org/hf/rule

 AND THE SECOND FOR A GOOD REASON. SARL states '2. Frequencies and modes Al
 l amateur bands and modes' -- there is no list to record\, and writing one
  out would be this catalog inventing a restriction SARL did not state. Sam
 e treatment as JARL's New Year QSO Party. The consequence is real and the 
 page says so: every band filter necessarily excludes this record.\n\nModes
  are 'Mixed' for the same sentence -- that is exactly what the token means
 .\n\nIt sits at the edge of what this catalog is for. It has dates\, rules
 \, an exchange and categories\, so it is a scheduled operating event with 
 a schedule worth publishing\; but it is scored through the SOTA database r
 ather than by a log submitted to the sponsor\, and 'Activator' and 'Chaser
 ' are roles rather than entry classes. Encoded on the same reasoning as UB
 A's Belgian Mills Award\, which is also an award-shaped event with real da
 tes. Sourced from the SARL Contest Manual\, which carries this contest's f
 ull rules and names its organising body -- the venue in which South Africa

DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2026-10-08\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

DESCRIPTION:Sponsor: ERAU\nModes: CW\, SSB\nBands: 80m\nBand note: CW below
  3600 kHz and SSB above it\; 3530-3560 kHz and 3600-3650 kHz are recommend
 ed.\nDuration: 59m\nExchange: RS(T) and a continuous serial number from 00
 1.\nEligibility: Entry limited to ES. K stations may be worked but cannot 
 submit an entry.\nNote: SPONSOR-ANCHORED LOCAL TIME\, and ERAU's own calen
 dar proves the reading: 10:00-10:59 Estonian time is 08:00-08:59 UTC in wi
 nter (EET) and 07:00-07:59 in summer (EEST)\, which is exactly the split E
 RAU prints across the nine stages. The rules give no date rule at all -- 4
 .2 defers to the calendar plan -- so the dates are manual and taken from E
 RAU's published 2026 calendar. Eight of the nine are the first Saturday of
  their month\; February's is the second. The log deadline is 'the Thursday
  of the following week'\, which is not a fixed number of days from the end
  of each stage\, so it is recorded here rather than as log_deadline_days. 
 Stages 4.3 also splits each hour into four periods\; that is a scoring dev
 ice inside one continuous hour.\nRules: https://www.erau.ee/images/LL/ES%2

 26 is the 3rd-4th\, which is what DARC prints. So this is a recurrence rat
 her than a date.\n\nFeld-Hell is a facsimile mode from the 1930s and has n

SUMMARY:RSGB 3.5 MHz Autumn Series\, CW
DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: CW\nBands: 80m\nBand no
 te: 3510-3565 kHz at any speed\, with 3565-3570 kHz reserved for 15 wpm ma
 ximum.\nDuration: 1h 30m\nExchange: RS(T) plus a serial number starting at
  1 and incrementing by 1.\nLogs due: 2026-10-08\nNote: THE CLOCK MOVES IN 
 NOVEMBER AND THE RECORD SAYS SO PER DATE. September and October run 1900-2
 030 UTC\; November runs 2000-2130. Every leg of this series sits on one si
 de or the other of that change\, so a single stored time would put two of 
 the three runnings on the calendar an hour wrong.\n\nThis is the first use
  of PER-DATE TIMES in a manual rule\, a schema question NEEDS_A_HUMAN had 
 been carrying since the REP FT4 series hit the same wall. The alternative 
 was one record per clock time -- six records for a nine-leg series the spo
 nsor treats as one -- or one record per leg\, which is nine. Splitting by 
 MODE is the split a reader actually wants\, because the mode filter is wha
 t they reach for\, and per-date times are what make that split possible wi
 thout lying about an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES DATES AND NO R
 ULE for this series. The legs fall on Mondays\, Wednesdays and Thursdays w
 ith no discernible ordinal\, which is exactly the shape an ordinal must no
 t be fitted to.\n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -- RSGB states
  it outright\, which is worth noting beside the AFS and Club Calls contest
 s where entry really is UK&CD only.\nRules: https://www.rsgbcc.org/hf/rule

 Exchange: RST\, the city\, county or ward number for where you are operati

  100116 H.\nEligibility: Entry limited to JA. K stations may be worked but
  cannot submit an entry.\nNote: THE ONLY RULE IN THE CATALOG ANCHORED ON A
  PUBLIC HOLIDAY AND COUNTED BACKWARDS. Japan's Sports Day is the second Mo
 nday of October\, and JARL hangs the contest on the weekend before it -- 
 前々日 and 前日\, two days before and one day before. It is encoded e
 xactly that way\, with negative day offsets from a Monday anchor\, rather 
 than as 'the second full weekend of October'\, which would be a different 
 rule that happens to agree in some years. Encoded as wall_clock in Asia/To
 kyo because that is how JARL states it -- 21時00分（JST） -- rather th
 an converted to a fixed UTC time by hand. Japan has not observed daylight 
 saving since 1952\, so the two are identical in practice and will stay so\
 ; the record says what the sponsor said and lets the engine do the arithme
 tic. log_deadline_days is absent. JARL prints a dated deadline above the r
 ules for the edition in hand -- ALL JA 2026 is '提出締切日 2026年5
 月6日（水）必着' -- and the numbered 規約 clauses that follow sta
 te the dates\, eligibility\, bands\, categories and exchange but no submis
 sion span. All four of JARL's 2026 deadlines happen to fall exactly ten da
 ys after their contest ends\, which is suggestive and is not a rule JARL w
 rote. The same reasoning already keeps a deadline off JARL's All Asian rec
 ords.\nRules: https://www.jarl.org/Japanese/1_Tanoshimo/1-1_Contest/acag_r

 it publishes complete rules at a domain of its own. SAC appeared nowhere i
 n the registry at all until the 2026-08-21 gap audit.\n\nTHE PAGE IS HEADE
 D 2023 AND THE RULE IS STATED AS STANDING. The recurrence sentences say 'e
 ach year'\, which is the form this catalog trusts -- the same form ARRL's 
 generic calendar uses -- and they reproduce that page's own 2023 dates. Re

 n: 1h 30m\nExchange: RS(T) plus a serial number starting at 1 and incremen
 ting by 1.\nLogs due: 2026-10-17\nNote: THE CLOCK MOVES IN NOVEMBER AND TH
 E RECORD SAYS SO PER DATE. September and October run 1900-2030 UTC\; Novem
 ber runs 2000-2130. Every leg of this series sits on one side or the other
  of that change\, so a single stored time would put two of the three runni
 ngs on the calendar an hour wrong.\n\nThis is the first use of PER-DATE TI
 MES in a manual rule\, a schema question NEEDS_A_HUMAN had been carrying s
 ince the REP FT4 series hit the same wall. The alternative was one record 
 per clock time -- six records for a nine-leg series the sponsor treats as 
 one -- or one record per leg\, which is nine. Splitting by MODE is the spl
 it a reader actually wants\, because the mode filter is what they reach fo
 r\, and per-date times are what make that split possible without lying abo
 ut an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES DATES AND NO RULE for this se
 ries. The legs fall on Mondays\, Wednesdays and Thursdays with no discerni
 ble ordinal\, which is exactly the shape an ordinal must not be fitted to.
 \n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -- RSGB states it outright\, 
 which is worth noting beside the AFS and Club Calls contests where entry r
 eally is UK&CD only.\nRules: https://www.rsgbcc.org/hf/rules/2026/rautumn.

DESCRIPTION:Sponsor: SARL\nModes: SSB\, CW\, RTTY\nBands: 80m\nBand note: P
 hone 3 603-3 650 and 3 703-3 800 kHz\; CW 3 510-3 560 kHz\; RTTY 3 580-3 6
 00 kHz. The segment 3 651-3 700 kHz is contest free.\nDuration: 1h\nExchan
 ge: Your name\, your Abbreviated Club Callsign and your 4-character grid s
 quare (for example KG30).\nEligibility: Entry limited to ZS. K stations ma
 y be worked but cannot submit an entry.\nNote: A club championship rather 
 than an individual contest: operators' scores are added into a club total.
  The month list is SARL's own -- these run in four months of the year\, no
 t every month -- which is what monthly_nth_weekday's `months` field exists
  for. log_format and log_deadline_days are absent: this pass read each con
 test's Aim\, Dates\, Frequencies and Exchange sections and did not read it
 s Log Sheets section\, so neither is recorded rather than assumed from SAR
 L's other contests.\n\nPROVENANCE RESTORED 2026-08-23. This record carried
  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th
 em: an empty string is not weak evidence\, it is none\, and there was noth
 ing in the record to check a rule against. The rule\, the times\, the band
 s and the exchange were all correct\; only the evidence for them was missi
 ng. Re-read from the manual and quoted above\, and SARL's own printed 2026
  dates reproduce it.\nRules: https://mysarl.org.za/wp-content/uploads/2025

DESCRIPTION:Sponsor: IRTS\nModes: CW\, SSB\nBands: 80m\nBand note: CW 3510-
 3560 kHz\; SSB 3600-3650 and 3700-3775 kHz.\nDuration: 1h\nExchange: EI an
 d GI stations send a signal report\, a serial number starting at 001 and t
 heir county. Everyone else sends the report and serial only.\nNote: THIS R
 ECORD WAS WRONG IN EVERY FIELD THAT MATTERED AND IS REWRITTEN. It was carr
 ied as the third Sunday of June\, 1300-1500 UTC\, with NO source_note at a
 ll -- a stub whose rule\, month\, weekday\, hour and duration were all inv
 ented. IRTS runs it three times a year for ONE HOUR each: 1 January\, 18 M
 arch and 21 October in 2026. Nothing about the old record survived contact
  with the sponsor's own calendar.\n\nIt was flagged `verified: false` thro
 ughout\, which is the only reason it was not a lie -- and it is exactly wh
 y the registry entry said 'that record is unverified\; source it'. An unve
 rified record is a promise to come back\, and this is what coming back fou
 nd.\n\nMANUAL\, AND THE NEW YEAR ROUND KEEPS ITS OWN HOUR. The January run
 ning is at 1700 UTC and the other two at 2000\, so the record's default is
  2000 and 1 January carries an override. There is no ordinal to derive: a 
 fixed New Year's Day round and two Wednesday evenings in March and October
  are not one pattern.\nRules: https://www.irts.ie/cgi/st.cgi?r_hfcrules.ht

DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: SSB\nBands: 80m\nBand n

 r starting at 1 and incrementing by 1.\nLogs due: 2026-10-25\nNote: THE CL
 OCK MOVES IN NOVEMBER AND THE RECORD SAYS SO PER DATE. September and Octob
 er run 1900-2030 UTC\; November runs 2000-2130. Every leg of this series s
 its on one side or the other of that change\, so a single stored time woul
 d put two of the three runnings on the calendar an hour wrong.\n\nThis is 
 the first use of PER-DATE TIMES in a manual rule\, a schema question NEEDS
 _A_HUMAN had been carrying since the REP FT4 series hit the same wall. The
  alternative was one record per clock time -- six records for a nine-leg s
 eries the sponsor treats as one -- or one record per leg\, which is nine. 
 Splitting by MODE is the split a reader actually wants\, because the mode 
 filter is what they reach for\, and per-date times are what make that spli
 t possible without lying about an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES D
 ATES AND NO RULE for this series. The legs fall on Mondays\, Wednesdays an
 d Thursdays with no discernible ordinal\, which is exactly the shape an or
 dinal must not be fitted to.\n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -
 - RSGB states it outright\, which is worth noting beside the AFS and Club 
 Calls contests where entry really is UK&CD only.\nRules: https://www.rsgbc

DESCRIPTION:Sponsor: SARL\nModes: FM\nBands: 6m\, 2m\, 70cm\nBand note: FM 
 mode on the 6m\, 2m and 70cm bands.\nDuration: 3h\nExchange: A signal repo
 rt and your full six-character Maidenhead locator. When working a mobile s
 tation the contesting station must obtain its grid position.\nEligibility:
  Entry limited to ZS\, V5\, A2\, Z2\, C9\, 7P\, 3DA. K stations may be wor
 ked but cannot submit an entry.\nNote: THE RECORD THAT PUT FM IN THE MODE 
 VOCABULARY. This contest is FM ONLY\, and until 2026-08-19 this catalog ha
 d no FM token -- it used SSB as a general phone token\, which was servicea
 ble while every phone contest also allowed SSB. Recording an FM-only conte
 st as SSB would have stated something SARL does not permit\, which is prec
 isely the overstatement the mode rules exist to prevent\, so FM was added 
 to CATALOG_MODES in both engines and to the filter families instead. Ten r
 ecords that had been carrying FM in submodes moved it into modes in the sa
 me commit.\n\nTwo legs on one record: both run 10:00-13:00 UTC and differ 
 only in their anchor\, and the anchors are different SHAPES -- the second 
 Saturday of June and the LAST Saturday of October -- which a composite hol
 ds without trouble.\n\nSARL explains the timing: 'The dates are three week
 s after the RAE Radio Amateur Examination'\, which is why the contest is a
 imed at newly licensed amateurs. That is context rather than a rule\; the 
 ordinals are what is encoded.\n\nNo log deadline was read in this pass\, s
 o none is recorded.\nRules: https://mysarl.org.za/wp-content/uploads/2025/

 NUAL\, AND THE SSB LEG IS WHY BOTH ARE. UKEICC publishes three years of da

  24 Apr 2027\; SSB on 1 Nov 2025\, 31 Oct 2026 and 23 Oct 2027.\n\nThe CW 
 dates happen to be the last Saturday of April in all three years. The SSB 
 dates fit nothing at all -- the FIRST Saturday of November\, then the FIFT
 H Saturday of October\, then the FOURTH -- not even the same month twice r
 unning. So this organiser demonstrably does not schedule by ordinal\, whic
 h is the strongest possible argument against fitting one to the CW leg bec
 ause three years happen to agree. Both legs hold exactly the dates UKEICC 
 printed and produce nothing for 2028 until it publishes them.\n\nFOUND THR
 OUGH RSGB'S HF CHAMPIONSHIP TABLE\, which lists the eleven contests that c
 ount towards it. That page is an award over other contests rather than a c
 ontest itself -- the same call already made about the WIA Contest Champion
  -- but it is an excellent index of what RSGB's season actually contains\,

 n: 1h 30m\nExchange: RS(T) plus a serial number starting at 1 and incremen
 ting by 1.\nLogs due: 2026-11-05\nNote: THE CLOCK MOVES IN NOVEMBER AND TH
 E RECORD SAYS SO PER DATE. September and October run 1900-2030 UTC\; Novem
 ber runs 2000-2130. Every leg of this series sits on one side or the other
  of that change\, so a single stored time would put two of the three runni
 ngs on the calendar an hour wrong.\n\nThis is the first use of PER-DATE TI
 MES in a manual rule\, a schema question NEEDS_A_HUMAN had been carrying s
 ince the REP FT4 series hit the same wall. The alternative was one record 
 per clock time -- six records for a nine-leg series the sponsor treats as 
 one -- or one record per leg\, which is nine. Splitting by MODE is the spl
 it a reader actually wants\, because the mode filter is what they reach fo
 r\, and per-date times are what make that split possible without lying abo
 ut an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES DATES AND NO RULE for this se
 ries. The legs fall on Mondays\, Wednesdays and Thursdays with no discerni
 ble ordinal\, which is exactly the shape an ordinal must not be fitted to.
 \n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -- RSGB states it outright\, 
 which is worth noting beside the AFS and Club Calls contests where entry r
 eally is UK&CD only.\nRules: https://www.rsgbcc.org/hf/rules/2026/rautumn.

 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2026-11-12\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 RAU prints across the nine stages. The rules give no date rule at all -- 4
 .2 defers to the calendar plan -- so the dates are manual and taken from E
 RAU's published 2026 calendar. Eight of the nine are the first Saturday of
  their month\; February's is the second. The log deadline is 'the Thursday
  of the following week'\, which is not a fixed number of days from the end
  of each stage\, so it is recorded here rather than as log_deadline_days. 
 Stages 4.3 also splits each hour into four periods\; that is a scoring dev
 ice inside one continuous hour.\nRules: https://www.erau.ee/images/LL/ES%2

SUMMARY:SARL QRP Contest (Spring leg)
DESCRIPTION:Sponsor: SARL\nModes: SSB\, CW\nBands: 40m\, 20m\, 10m\nBand no
 te: 40m\, 20m and 10m\, any of them at any time during the contest. QRP ca
 lling frequencies 7.090\, 14.285 and 28.360 MHz are suggested.\nDuration: 
 2h\nExchange: Realistic RS(T)\, 6-character grid square and transmit power
  in watts (for example 57\, KG33uk\, 10).\nNote: The spring leg is the Nov
 ember one -- the seasons are southern hemisphere\, so January is summer. O
 ne of SARL's four named QRP legs. They are four records rather than one be
 cause SARL names four legs by season and they do not share a clock: the Su
 mmer and Winter legs run 07:00-09:00 UTC and the Autumn and Spring legs 13
 :30-15:30\, so no single start/end pair covers them. Grouping the two pair
 s by their times would have been this catalog inventing a structure SARL d
 oes not use. log_format and log_deadline_days are absent: this pass read e
 ach contest's Aim\, Dates\, Frequencies and Exchange sections and did not 
 read its Log Sheets section\, so neither is recorded rather than assumed f
 rom SARL's other contests.\nRules: https://mysarl.org.za/wp-content/upload

DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: SSB\nBands: 80m\nBand n

 r starting at 1 and incrementing by 1.\nLogs due: 2026-11-14\nNote: THE CL
 OCK MOVES IN NOVEMBER AND THE RECORD SAYS SO PER DATE. September and Octob
 er run 1900-2030 UTC\; November runs 2000-2130. Every leg of this series s
 its on one side or the other of that change\, so a single stored time woul
 d put two of the three runnings on the calendar an hour wrong.\n\nThis is 
 the first use of PER-DATE TIMES in a manual rule\, a schema question NEEDS
 _A_HUMAN had been carrying since the REP FT4 series hit the same wall. The
  alternative was one record per clock time -- six records for a nine-leg s
 eries the sponsor treats as one -- or one record per leg\, which is nine. 
 Splitting by MODE is the split a reader actually wants\, because the mode 
 filter is what they reach for\, and per-date times are what make that spli
 t possible without lying about an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES D
 ATES AND NO RULE for this series. The legs fall on Mondays\, Wednesdays an
 d Thursdays with no discernible ordinal\, which is exactly the shape an or
 dinal must not be fitted to.\n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -
 - RSGB states it outright\, which is worth noting beside the AFS and Club 
 Calls contests where entry really is UK&CD only.\nRules: https://www.rsgbc

 Note: PARTLY UNVERIFIED. The recurrence (every Monday)\, the 1740 UTC pre-
 logging opening and the 1800 UTC telegram transmission are all quoted from
  AGCW. AGCW publishes NO closing time. The 1830 end stored here is a PLACE
 HOLDER so the record expands -- it is not a sponsor fact and must not be p
 resented as one. Confirm the session length with the ZMC manager before sh
 ipping. Points accumulate over a calendar year\; logs are due 31 January o
 f the following year.\nUNVERIFIED: these dates have not yet been checked a
 gainst the sponsor's own published rules. Confirm before you rely on them.

SUMMARY:RSGB FT4 Contest Series
DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: FT8/FT4 (FT4)\nBands: 8
 0m\, 40m\, 20m\, 15m\, 10m\nBand note: 80\, 40\, 20\, 15 and 10 m.\nDurati
 on: 2h\nExchange: A signal report. A serial number is not required.\nLogs 
 due: 2026-11-17\nNote: TWELVE MONDAY EVENINGS AND THE CLOCK SHIFTS FOR THE
  SUMMER: January to March and October to December run 2000-2200 UTC\, Apri
 l to September run 1900-2100. Six legs each way\, so the record's default 
 is the winter clock and the summer legs carry their own -- the third conte
 st to need per-date times\, after the Autumn Series and the 80m Club Champ
 ionship.\n\nMANUAL BECAUSE THE DATES ARE NOT ON THE RULES PAGE and follow 
 no ordinal: they are Mondays\, but the third Monday in January\, the fourt
 h in February\, the third in March. RSGB publishes them on its CGI calenda
 r and this record holds what that prints.\n\nNot the same contest as the F
 T4 International Activity Day in April\, which is 24 hours and has its own
  rules page.\nRules: https://www.rsgbcc.org/hf/rules/2026/r80m_ft4.shtml

SUMMARY:DARC HELL-Kurzcontest (unverified)
DESCRIPTION:Sponsor: DARC\nModes: Digital (Hell)\nBands: not yet read off t
 he sponsor's own rules\nDuration: 59m\nExchange: not recorded yet — see 
 the sponsor's rules below\nNote: VERIFIED FALSE\, AND THE RECURRENCE IS ST
 ILL DERIVED FROM DARC'S OWN FOUR DATES. All four are the THIRD TUESDAY of 
 the second month of each quarter -- 17 Feb\, 19 May\, 18 Aug\, 17 Nov 2026
  -- which is a clean pattern across four points and sits alongside the RTT
 Y-Kurzcontest (2nd Tuesday\, months 1/4/7/10) and the FT4 Contest (2nd Tue
 sday\, months 2/5/8/11) that DARC already runs.\n\nWhat is missing is ever
 ything the rules page would give: BANDS ARE UNRECORDED\, so every band fil
 ter excludes this record\, and the exchange and deadline are absent. The m
 ode is taken from the contest's own name. That is why it is unverified: th
 e dates are DARC's\, the rule is an inference from them\, and the rest is 
 a gap.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not read: this series has no Au
 sschreibung linked from DARC's table. That sentence sits here rather than 
 in bands_note\, because bands_note is for a sponsor's own wording ABOUT a 
 band list and must never stand in for one -- a test enforces it\, and it c
 aught this.\nUNVERIFIED: these dates have not yet been checked against the
  sponsor's own published rules. Confirm before you rely on them.\nRules: h

DESCRIPTION:Sponsor: BFRA\nModes: CW\, SSB\nBands: 80m\, 40m\, 20m\, 15m\,

  their ITU zone\; LZ stations send RS(T) and a two-letter district abbrevi
 ation.\nNote: 'The weekend before the last full weekend of November' is a 
 rule\, not an annual announcement -- BFRA anchors it to CQ WW CW\, which s
 its on the last one -- so it is encoded as n=-2 and this is the record tha
 t made the engine count backwards past 'last'. November 2025's full weeken
 ds are the 1st/2nd\, 8th/9th\, 15th/16th\, 22nd/23rd and 29th/30th\, so n=
 -2 gives 22-23 November\, the date BFRA prints. For 2026 it gives 21-22 No
 vember. The log deadline is a stated instant (0000Z on 7 December 2025) an
 d not the contest end plus a whole number of days\, so it is recorded here
  rather than as log_deadline_days. REGISTRY CORRECTION: BFRA is at bfra.bg

DESCRIPTION:Sponsor: ÖVSV\nModes: CW\nBands: 160m\nBand note: 1810-2000 kH
 z in the German rules\; the English rules say 1810-1950 kHz. Both are OEVS
 V's own statements and neither has been withdrawn.\nDuration: 7h 59m\nExch
 ange: RST and a serial number\; Austrian stations add their OE district id
 entifier.\nNote: The third full weekend of November is a rule OEVSV states
  twice\, in German and in English\, and it reproduces the date the German 
 edition prints for itself: November 2025's full weekends are the 1st/2nd\,
  8th/9th and 15th/16th\, so the third is Saturday 15 November 2025. For 20
 26 the 1st is a Sunday whose Saturday belongs to October\, so the full wee
 kends start on the 7th/8th and the rule gives Saturday 21 November 2026. C
 ONTRADICTIONS\, recorded not reconciled: the German rules say 1810-2000 kH
 z and the English 1810-1950 kHz\; the German rules take logs at aoec-auswe
 rtung.oevsv.at and the English at contestrobot.aoec160m.oevsv.at\, so neit
 her is encoded as the log_submit_url. The deadline is a fixed date (30 Nov
 ember)\, not an interval. BLOCKER: OEVSV's HF-Referat page still offers on
 ly the 2025 Ausschreibung\, so this is the current published document and 
 it is on the pending list to re-read.\nRules: https://www.oevsv.at/export/

 2026-11-30\nNote: log_deadline_days is derived\, not quoted: REF words the
  deadline as 'le deuxieme lundi apres le concours' and states no hour. The
  contest ends at 0000 UTC on the Sunday\, and that Sunday plus 8 days is t
 he second Monday after the contest in every year\, so 8 is exact for the d
 ate and silent about the time of day. WORDING DIFFERENCE\, RECORDED RATHER
  THAN RECONCILED: this PDF says 'Troisieme week-end de novembre' while the
  Coupe du REF PDF\, describing the same sub-part in section 1(a)\, says 'T
 roisieme week-end entier du mois de novembre'. The two readings cannot div
 erge -- the third Saturday of November is at most the 21st\, so its Sunday
  is always in November -- so no choice between them was needed.\nRules: ht

SUMMARY:RSGB 3.5 MHz Autumn Series\, CW
DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: CW\nBands: 80m\nBand no
 te: 3510-3565 kHz at any speed\, with 3565-3570 kHz reserved for 15 wpm ma
 ximum.\nDuration: 1h 30m\nExchange: RS(T) plus a serial number starting at
  1 and incrementing by 1.\nLogs due: 2026-11-29\nNote: THE CLOCK MOVES IN 
 NOVEMBER AND THE RECORD SAYS SO PER DATE. September and October run 1900-2
 030 UTC\; November runs 2000-2130. Every leg of this series sits on one si
 de or the other of that change\, so a single stored time would put two of 
 the three runnings on the calendar an hour wrong.\n\nThis is the first use
  of PER-DATE TIMES in a manual rule\, a schema question NEEDS_A_HUMAN had 
 been carrying since the REP FT4 series hit the same wall. The alternative 
 was one record per clock time -- six records for a nine-leg series the spo
 nsor treats as one -- or one record per leg\, which is nine. Splitting by 
 MODE is the split a reader actually wants\, because the mode filter is wha
 t they reach for\, and per-date times are what make that split possible wi
 thout lying about an hour.\n\nMANUAL BECAUSE RSGB PUBLISHES DATES AND NO R
 ULE for this series. The legs fall on Mondays\, Wednesdays and Thursdays w
 ith no discernible ordinal\, which is exactly the shape an ordinal must no
 t be fitted to.\n\nNON-UK STATIONS MAY ENTER AS INDIVIDUALS -- RSGB states
  it outright\, which is worth noting beside the AFS and Club Calls contest
 s where entry really is UK&CD only.\nRules: https://www.rsgbcc.org/hf/rule

 60 kHz. The segment 7 101-7 129 kHz is contest free.\nDuration: 1h\nExchan
 ge: Your name\, your Abbreviated Club Callsign and your 4-character grid s
 quare (for example KG30).\nEligibility: Entry limited to ZS. K stations ma
 y be worked but cannot submit an entry.\nNote: A club championship rather 
 than an individual contest: operators' scores are added into a club total.
  The month list is SARL's own -- these run in four months of the year\, no
 t every month -- which is what monthly_nth_weekday's `months` field exists
  for. log_format and log_deadline_days are absent: this pass read each con
 test's Aim\, Dates\, Frequencies and Exchange sections and did not read it
 s Log Sheets section\, so neither is recorded rather than assumed from SAR
 L's other contests.\n\nPROVENANCE RESTORED 2026-08-23. This record carried
  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th
 em: an empty string is not weak evidence\, it is none\, and there was noth

DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2026-12-10\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 dar proves the reading: 10:00-10:59 Estonian time is 08:00-08:59 UTC in wi
 nter (EET) and 07:00-07:59 in summer (EEST)\, which is exactly the split E
 RAU prints across the nine stages. The rules give no date rule at all -- 4
 .2 defers to the calendar plan -- so the dates are manual and taken from E
 RAU's published 2026 calendar. Eight of the nine are the first Saturday of
  their month\; February's is the second. The log deadline is 'the Thursday
  of the following week'\, which is not a fixed number of days from the end
  of each stage\, so it is recorded here rather than as log_deadline_days. 
 Stages 4.3 also splits each hour into four periods\; that is a scoring dev
 ice inside one continuous hour.\nRules: https://www.erau.ee/images/LL/ES%2

DESCRIPTION:Sponsor: ARSI\nModes: CW\nBands: 40m\nDuration: 23h 59m\nExchan
 ge: A serial number starting at 001\, with the signal report.\nEligibility
 : Entry limited to VU. K stations may be worked but cannot submit an entry
 .\nLogs due: 2026-12-13\nNote: STATED IN IST ONLY\, unlike ARSI's other co
 ntests\, which give UTC. So this record carries Asia/Kolkata wall clock ra
 ther than a UTC time converted by hand -- India is a fixed +05:30 with no 
 daylight saving\, so 19:30 IST is 14:00 UTC and always will be\, but the r
 ecord says what the page said. The log deadline is one of the few here sta
 ted as a SPAN rather than a date: 'within a week'\, 'due in 7 days time fr
 om the date of contest'. ARSI PUBLISHES DATES\, NOT A RECURRENCE. Every on
 e of its contest pages opens with the year's dates and states no rule anyw
 here -- no 'annually on'\, no ordinal weekend. So all five records are man
 ual and hold exactly the 2026 editions ARSI published. Fitting an ordinal 
 to one date would be inventing a rule ARSI has not written\, and Asia is t
 hin enough that the temptation is worth naming.\nRules: https://arsi.info/

 m\, 40m\, 20m\, 15m\, 10m\nBand note: 80 through 10 metres\, no WARC bands

  serial number from 001.\nNote: THE SPONSOR FIELD IS AN ATTRIBUTION\, NOT 
 A QUOTATION. The rules page names no organising body at all -- it credits 
 a wine sponsor for the awards and nothing else -- so 'RTTY Contesting' her
 e is the site that publishes and runs it rather than a society that claims
  it. Recorded this way for the same reason the OK DX RTTY Contest is: an i
 nferred organiser is better stated than implied. Worth one question to who
 ever answers the log address.\n\nThe page still shows 2023's dates beside 
 a rule stated in general terms\, so the rule is what is encoded. Re-read i
 t nearer December.\nRules: https://www.rttycontesting.com/ft-roundup/rules

 on Tuesday UTC -- and those are different dates whenever the 1st falls on 
 a Tuesday (Sep and Dec 2026). SPONSOR-ANCHORED LOCAL TIME: ARS publishes n
 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n
 ot\, is the one place the sponsor's own table is inconsistent.\nRules: htt

DESCRIPTION:Sponsor: DARC\nModes: CW\nBands: not yet read off the sponsor's
  own rules\nDuration: 59m\nExchange: not recorded yet — see the sponsor'
 s rules below\nNote: IT COMPLETES A PATTERN DARC DESCRIBES BUT DOES NOT SP
 ELL OUT. Their three short contests take one month of each quarter in turn
 \, all on a Tuesday evening: the RTTY-Kurzcontest in months 1/4/7/10\, the
  FT4 Contest in 2/5/8/11\, and this one in 3/6/9/12. All four of DARC's pu
 blished dates are the SECOND TUESDAY of those months. That is what 'reiht 
 sich vom Termin her in die anderen ... ein' means\, and the arithmetic con
 firms it rather than assuming it.\n\nVERIFIED FALSE because the page that 
 describes the series is prose about teaching CW rather than an Ausschreibu
 ng: no bands\, no exchange\, no deadline. BANDS ARE UNRECORDED\, so every 
 band filter excludes this record.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not 
 stated on the page that describes the series. That sentence sits here rath
 er than in bands_note\, because bands_note is for a sponsor's own wording 
 ABOUT a band list and must never stand in for one -- a test enforces it\, 
 and it caught this.\nUNVERIFIED: these dates have not yet been checked aga
 inst the sponsor's own published rules. Confirm before you rely on them.\n

 cannot submit an entry.\nNote: USKA runs the Weihnachtswettbewerb on two S
 aturdays\, and each Saturday is a phone-or-CW morning followed by a separa
 te digital hour. This record is the second Saturday: CW 07:00-09:59 UTC an
 d digital 10:00-10:59 UTC\, encoded as two sessions because the hour betwe
 en them is not part of the contest. The two Saturdays are two records beca
 use they are different modes\, not two legs of one event. The first Saturd
 ay of December 2026 is the 5th and the second the 12th\, the dates USKA's 
 KW-Contest page prints. USKA states no log deadline in this Reglement -- t

 resented as one. Confirm the session length with the ZMC manager before sh

 E SPONSOR'S OWN TEXT\, BOTH RECORDED RATHER THAN RECONCILED. First\, the n
 ews item announcing the 19 December 2026 edition prints 'Deadline for log 
 upload: 26. 12. 2025 23:59:59' -- the wrong year for a 2026 contest. Secon
 d\, that 26 December date is not what the rules' own seven-day interval pr
 oduces here: this catalog stores the end as 24:00 on the Saturday\, i.e. 0
 0:00 on the Sunday\, and seven days from there is 27 December. log_deadlin
 e_days is therefore left unset and both statements are quoted\, the same t
 reatment given to JARL's All Asian DX Contest. ATTRIBUTION CAVEAT: neither
  the English nor the Czech rules page names an organising society. The spo
 nsor is recorded as the Czech Radio Club on the strength of the crk.cz hos
 ting domain and the okrtty-at-crk.cz log address\, and that inference is s
 tated here rather than hidden. BLOCKER: okrtty.crk.cz serves a TLS certifi
 cate issued for default.web4u.cz\, so rules_url is http:// deliberately.\n

SUMMARY:RSGB AFS Contest\, CW
DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: CW\nBands: 80m\, 40m\nB
 and note: 80 m and 40 m. CW 3510-3570 and 7000-7040 kHz\; SSB 3600-3775 an
 d 7060-7200 kHz\; PSK63 3580-3590 and 7040-7045 kHz\; RTTY 3590-3620 and 7
 045-7060 kHz.\nDuration: 4h\nExchange: RS(T) plus a serial number starting
  at 1 and incrementing by 1\, irrespective of band.\nEligibility: Entry li
 mited to G. K stations may be worked but cannot submit an entry.\nNote: AL
 L THREE HANG OFF ONE ANCHOR\, WHICH IS WHAT FIVE YEARS OF RSGB'S DATES SHO
 W. The AFS CW Saturday is the anchor\; Datamodes is the Sunday eight days 
 later and SSB the Saturday fourteen days later. No consistent ordinal desc
 ribes Datamodes on its own -- it is the third Sunday in 2022 and 2023 and 
 the second in 2024\, 2025 and 2026 -- so encoding it as an ordinal would h
 ave been wrong in two of the five years RSGB published.\n\nTHE 1 JANUARY E
 XCEPTION IS EVIDENCED\, NOT ASSUMED. 1 January 2022 was itself a Saturday 
 and RSGB ran AFS CW on the 8th\, so `exclude_dates: [[1\, 1]]` is what rep
 roduces that year -- the same shape ARRL RTTY Roundup states outright for 
 its own New Year clash. RSGB does not state it in words\, but unlike TRAC'
 s equivalent this is not a single year's evidence fitted to a rule: it is 
 the only reading that fits all five years across all three contests. It ne
 xt decides anything in 2028.\n\nPREVIOUSLY UNVERIFIED\, AND THE GUESS WAS 
 RIGHT ABOUT THE RULE AND WRONG ABOUT NOTHING ELSE. This record was carried
  with a guessed rules URL that 404'd\, and the note asked someone to find 
 the real page under rsgbcc.org/hf/. It is at /hf/rules/{year}/rafs.shtml\,
  which is now the record's rules_url_pattern. The first-Saturday recurrenc
 e and the 1300-1700 times the record already held were correct\; what was 
 missing was the 1 January exception\, and the two sibling contests.\nRules

DESCRIPTION:Sponsor: ARRL\nModes: SSB\nBands: 80m\, 40m\, 20m\, 17m\, 15m\,
  12m\, 10m\nBand note: Suggested frequencies on each band\, for example 28
 .350-28.400 MHz on 10 m. Local repeaters may also be used with the owner's
  permission.\nDuration: 5h 59m\nExchange: Name\, age\, location and favour
 ite colour.\nNote: UNVERIFIED ON PURPOSE\, AND THE HEDGE IS ARRL'S OWN. Th
 eir page says 'GENERALLY the first Saturday in January' -- and ARRL's Gene
 ric Contest Calendar\, which states every other ARRL recurrence flatly\, l
 ists only the June running and gives it as 'Third Saturday in June' with n
 o hedge at all. So the January date is stated once\, softly\, in one place
 . The record carries the hedge as a hedge rather than promoting it to a ru
 le.\n\nThe catalog held the June running from the first seeding pass and n
 ever had this one\, from a sponsor with 21 encoded records -- which is the
  gap audit's second finding in miniature: the bias was not only across spo
 nsors but WITHIN them.\nUNVERIFIED: these dates have not yet been checked 
 against the sponsor's own published rules. Confirm before you rely on them

  a serial number from 001 and a six-character WW locator.\nLogs due: 2027-
 01-04\nNote: Encoded as the first Sunday in January\, which gives 4 Januar
 y 2026 -- the date LRMD prints. CAVEAT: LRMD's two wordings diverge in the
  years when 1 January is itself a Sunday. 'The first Sunday AFTER New Year
 's Day' would then be the 8th\, while the first Sunday IN January is the 1
 st. No such year has been published by LRMD\, so neither reading can be te
 sted against a sponsor date\; the first-Sunday reading is encoded and the 
 divergence recorded rather than resolved. FM is in submodes because it is 
 not in the catalog's mode vocabulary.\nRules: https://lrmd.lt/vmc/

 Note: PARTLY UNVERIFIED. The recurrence (every Monday)\, the 1740 UTC pre-

  AGCW. AGCW publishes NO closing time. The 1830 end stored here is a PLACE

 on Tuesday UTC -- and those are different dates whenever the 1st falls on 
 a Tuesday (Sep and Dec 2026). SPONSOR-ANCHORED LOCAL TIME: ARS publishes n
 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n
 ot\, is the one place the sponsor's own table is inconsistent.\nRules: htt

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-01-14\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 NE 44-HOUR BLOCK\, and the distinction is the sponsor's own: PEARS scores 
 them separately and says so. They are back to back -- the second 'commence

 4-hour occurrence would draw the same bar on the rail and lose the fact th

 this catalog's band vocabulary\, so it is recorded only here.\nDuration: 2
 2h\nExchange: A signal report and locator\, per the contest's channel plan
 .\nEligibility: Entry limited to ZS\, V5\, A2\, Z2\, C9\, 7P\, 3DA. K stat
 ions may be worked but cannot submit an entry.\nNote: TWO SESSIONS\, NOT O
 NE 44-HOUR BLOCK\, and the distinction is the sponsor's own: PEARS scores 
 them separately and says so. They are back to back -- the second 'commence
 s immediately after' the first ends at 14:00 UTC Saturday -- so a single 4
 4-hour occurrence would draw the same bar on the rail and lose the fact th
 at they are two scored periods. The anchor is the 2nd FRIDAY of January\, 
 which is how PEARS phrases it. Sourced from the SARL Contest Manual\, whic
 h carries this contest's full rules and names its organising body -- the v
 enue in which South African clubs publish their rules\, not a listing of t
 hem. See data/sources.md\, 'Nine South African clubs\, one manual'.\nRules

 mer and Winter legs run 07:00-09:00 UTC and the Autumn and Spring legs 13:
 30-15:30\, so no single start/end pair covers them. Grouping the two pairs

 60 kHz. The segment 7 101-7 129 kHz is contest free.\nDuration: 1h\nExchan
 ge: Your name\, your Abbreviated Club Callsign and your 4-character grid s
 quare (for example KG30).\nEligibility: Entry limited to ZS. K stations ma
 y be worked but cannot submit an entry.\nNote: A club championship rather 
 than an individual contest: operators' scores are added into a club total.
  The month list is SARL's own -- these run in four months of the year\, no
 t every month -- which is what monthly_nth_weekday's `months` field exists
  for. log_format and log_deadline_days are absent: this pass read each con
 test's Aim\, Dates\, Frequencies and Exchange sections and did not read it
 s Log Sheets section\, so neither is recorded rather than assumed from SAR
 L's other contests.\n\nPROVENANCE RESTORED 2026-08-23. This record carried
  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th
 em: an empty string is not weak evidence\, it is none\, and there was noth
 ing in the record to check a rule against. The rule\, the times\, the band
 s and the exchange were all correct\; only the evidence for them was missi
 ng. Re-read from the manual and quoted above\, and SARL's own printed 2026

 etre bands only.\nDuration: 12h\nExchange: RS(T) or SNR followed by a four
 -character grid square.\nNote: ANCHORED ON A PUBLIC HOLIDAY AND STARTING T
 HE DAY BEFORE IT. Australia Day is 26 January\, and the contest opens at 2
 200 UTC on the 25th -- which is 0900 on the 26th in eastern Australia. So 
 the record's anchor is the 26th with a day_offset of -1 on the start\, exa
 ctly as WIA states it\, rather than a rule about the 25th.\n\nModes: WIA's
  'Phone' covers AM\, FM and SSB and scores as one mode\, so SSB and FM are
  both recorded -- both are permitted -- and AM sits in submodes because it
  has no token in this catalog. FT8/FT4 is a separate scored section.\n\nNo
  log deadline is stated on the page.\nRules: https://www.wia.org.au/member

 N IN REF'S OWN DOCUMENT\, RECORDED RATHER THAN RECONCILED: section 1(b) sc
 opes these two parts to 'Bandes HF (80-10 m)' and the English rules list '
 80\, 40\, 20\, 15\, 10 m'\, but section 3(c) of the same PDF says 'Segment
 s concours IARU des bandes 160\, 80\, 40\, 20\, 15 et 10 metres'. The docu
 ment also governs the 160 m sub-part (REF 160 Metres\, a separate record h
 ere)\, which is the likely reason the band is listed in 3(c)\; the 80-10 m
  reading is encoded because it is the one that scopes these parts specific
 ally and the one the English rules repeat. REF's common HF rules ('Regles 
 communes a tous les concours HF'\, 6A) state the deadline as '8 (huit) jou
 rs apres la fin du concours a minuit heure legale francaise'\, so the comp
 uted instant here is the end plus 8 days rather than French legal midnight

 uration: 24h\nExchange: Stations on Belgian territory send RS(T) + serial 
 number starting with 001 + the abbreviation of their UBA section (e.g. 590
 01 ACC)\; non-members send XXX and the national stations send UBA. Station
 s outside Belgium send RS(T) + serial number starting from 001.\nLogs due:
  2027-02-07\nNote: LAST SATURDAY\, NOT LAST FULL WEEKEND\, and UBA's own 2
 026 dates are what settle it: 31 January 2026 is a Saturday and 1 February
  is a Sunday\, so the last full weekend of January 2026 would be 24-25 Jan
 uary. UBA published 31 January - 1 February\, which only the last-Saturday
  reading produces. The QRP figure recorded here is the SSB one\; UBA's rul
 e is 'QRP SSB maximum 10 Watts output\, CW maximum 5 Watts output.' The st
 ated deadline instants (SSB 8 February 23:59 UTC\, CW 8 March 23:59 UTC) a
 re the right dates for a 7-day interval but 23:59 rather than the 13:00 th
 at end-plus-7-days gives\; the interval is what UBA states as the rule\, s
 o it is what is encoded.\nRules: https://www.uba.be/en/hf/contest-rules/ub

 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-02-11\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

DESCRIPTION:Sponsor: HamSat-SA\nModes: SSB\nBands: 3cm\nBand note: Through 
 the QO-100 geostationary satellite: SSB on 10 489.870 to 10 489.990 MHz\, 
 which is the 3 cm band.\nDuration: 2h\nExchange: RS and grid locator.\nNot
 e: THE CATALOG'S FIRST SATELLITE CONTEST. Every contact is through QO-100\
 , the geostationary amateur transponder\, so the band recorded is 3 cm -- 
 the 10 489 MHz downlink -- and a band filter will find it there. That is t
 he honest token for the frequency in use\, but it is worth knowing that th
 is contest is nothing like the other 3 cm entries in the catalog: no terre
 strial path is involved\, and the equipment is a dish rather than a microw
 ave rig. SOURCED FROM THE SARL CONTEST MANUAL\, WHICH IS NOT AN AGGREGATOR
 . The manual carries this contest's FULL rules -- aim\, dates\, exchange\,
  frequencies\, scoring\, log sheets -- and names its organising club\, rat
 her than summarising a calendar entry. It is the venue in which South Afri
 can clubs publish their contest rules\, the way DARC's Ausschreibungen or 
 UBA's rules pages are\, so it is a primary source for these contests and n
 ot a third-party listing. The distinction that matters: an aggregator repu
 blishes rules it found elsewhere\, and this is where the rules appear.\nRu

DESCRIPTION:Sponsor: DARC\nModes: Digital (Hell)\nBands: not yet read off t
 he sponsor's own rules\nDuration: 59m\nExchange: not recorded yet — see 
 the sponsor's rules below\nNote: VERIFIED FALSE\, AND THE RECURRENCE IS ST
 ILL DERIVED FROM DARC'S OWN FOUR DATES. All four are the THIRD TUESDAY of 
 the second month of each quarter -- 17 Feb\, 19 May\, 18 Aug\, 17 Nov 2026
  -- which is a clean pattern across four points and sits alongside the RTT
 Y-Kurzcontest (2nd Tuesday\, months 1/4/7/10) and the FT4 Contest (2nd Tue
 sday\, months 2/5/8/11) that DARC already runs.\n\nWhat is missing is ever
 ything the rules page would give: BANDS ARE UNRECORDED\, so every band fil
 ter excludes this record\, and the exchange and deadline are absent. The m
 ode is taken from the contest's own name. That is why it is unverified: th
 e dates are DARC's\, the rule is an inference from them\, and the rest is 
 a gap.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not read: this series has no Au
 sschreibung linked from DARC's table. That sentence sits here rather than 
 in bands_note\, because bands_note is for a sponsor's own wording ABOUT a 
 band list and must never stand in for one -- a test enforces it\, and it c
 aught this.\nUNVERIFIED: these dates have not yet been checked against the
  sponsor's own published rules. Confirm before you rely on them.\nRules: h

  The month list is SARL's own -- these run in four months of the year\, no

  for. log_format and log_deadline_days are absent: this pass read each con
 test's Aim\, Dates\, Frequencies and Exchange sections and did not read it

  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th

 uration: 36h\nExchange: French metropolitan stations send RS(T) + the numb
 er of the department where the antenna is located (e.g. 599 69)\; F6REF\, 
 the REF's official station\, sends RS(T) + 00. DOM/TOM stations send RS(T)
  + the prefix of their entity (e.g. 599 FM). Foreign stations send RS(T) +
  a serial number starting at 001.\nLogs due: 2027-03-08\nNote: CONTRADICTI
 ON IN REF'S OWN DOCUMENT\, RECORDED RATHER THAN RECONCILED: section 1(b) s
 copes these two parts to 'Bandes HF (80-10 m)' and the English rules list 
 '80\, 40\, 20\, 15\, 10 m'\, but section 3(c) of the same PDF says 'Segmen
 ts concours IARU des bandes 160\, 80\, 40\, 20\, 15 et 10 metres'. The doc
 ument also governs the 160 m sub-part (REF 160 Metres\, a separate record 
 here)\, which is the likely reason the band is listed in 3(c)\; the 80-10 
 m reading is encoded because it is the one that scopes these parts specifi
 cally and the one the English rules repeat. REF's common HF rules ('Regles
  communes a tous les concours HF'\, 6A) state the deadline as '8 (huit) jo
 urs apres la fin du concours a minuit heure legale francaise'\, so the com
 puted instant here is the end plus 8 days rather than French legal midnigh
 t.\nRules: https://concours.r-e-f.org/reglements/actuels/reg_cdfhf_fr_2026

 1 ACC)\; non-members send XXX and the national stations send UBA. Stations
  outside Belgium send RS(T) + serial number starting from 001.\nLogs due: 
 2027-03-07\nNote: LAST SATURDAY\, NOT LAST FULL WEEKEND\, and UBA's own 20
 26 dates are what settle it: 31 January 2026 is a Saturday and 1 February 
 is a Sunday\, so the last full weekend of January 2026 would be 24-25 Janu
 ary. UBA published 31 January - 1 February\, which only the last-Saturday 
 reading produces. The QRP figure recorded here is the SSB one\; UBA's rule
  is 'QRP SSB maximum 10 Watts output\, CW maximum 5 Watts output.' The sta
 ted deadline instants (SSB 8 February 23:59 UTC\, CW 8 March 23:59 UTC) ar
 e the right dates for a 7-day interval but 23:59 rather than the 13:00 tha
 t end-plus-7-days gives\; the interval is what UBA states as the rule\, so

 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n
 ot\, is the one place the sponsor's own table is inconsistent.\nRules: htt

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-03-11\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 which gives 8 March 2026 -- the date MRASZ prints -- because 8 March 2026

DESCRIPTION:Sponsor: DARC\nModes: CW\nBands: not yet read off the sponsor's
  own rules\nDuration: 59m\nExchange: not recorded yet — see the sponsor'
 s rules below\nNote: IT COMPLETES A PATTERN DARC DESCRIBES BUT DOES NOT SP
 ELL OUT. Their three short contests take one month of each quarter in turn
 \, all on a Tuesday evening: the RTTY-Kurzcontest in months 1/4/7/10\, the
  FT4 Contest in 2/5/8/11\, and this one in 3/6/9/12. All four of DARC's pu
 blished dates are the SECOND TUESDAY of those months. That is what 'reiht 
 sich vom Termin her in die anderen ... ein' means\, and the arithmetic con
 firms it rather than assuming it.\n\nVERIFIED FALSE because the page that 
 describes the series is prose about teaching CW rather than an Ausschreibu
 ng: no bands\, no exchange\, no deadline. BANDS ARE UNRECORDED\, so every 
 band filter excludes this record.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not 
 stated on the page that describes the series. That sentence sits here rath
 er than in bands_note\, because bands_note is for a sponsor's own wording 
 ABOUT a band list and must never stand in for one -- a test enforces it\, 
 and it caught this.\nUNVERIFIED: these dates have not yet been checked aga
 inst the sponsor's own published rules. Confirm before you rely on them.\n

 one and CW on one band count as separate bands and a station may be worked
  once per band per mode.\nLogs due: 2027-03-19\nNote: Two legs a year off 
 ONE record\, because both share a start and end offset -- 0800 UTC Saturda
 y to 1000 UTC Sunday -- and differ only in which weekend they anchor to. S
 ARL states both readings itself\, weekend AND date\, and both agree for 20
 26. log_deadline_days is 5\, which is the right DAY and not the right hour
 : SARL states 'by 21:59 UTC on Friday'\, and the contest ends at 10:00 UTC
  on the Sunday five days before\, so the engine's derived log_due lands at
  17:00 rather than 21:59. The day is exact in every year because both ends
  are tied to the same Sunday. The five hours are recorded here rather than
  papered over.\nRules: https://mysarl.org.za/wp-content/uploads/2025/11/20

 20m\, 15m\, 10m\nBand note: 3.5\, 7\, 14\, 21 and 28 MHz.\nDuration: 24h\n
 Exchange: RST plus a serial number starting at 1 and incrementing by 1\, i
 rrespective of band. Commonwealth society headquarters stations add 'HQ' a
 fter the serial.\nEligibility: Entry limited to 151 listed entities. K sta
 tions may be worked but cannot submit an entry.\nLogs due: 2027-03-19\nNot
 e: DEFERRED SINCE 2026-08-20 ON ELIGIBILITY\, NOT ON READING\, AND NOW RES
 OLVED. The recurrence and the running were never in doubt\; what blocked i
 t was that the rules restrict entry to 'the Commonwealth Call Area list' a
 nd the rules page does not print that list. Writing an entity_list from ge
 neral knowledge of the Commonwealth would have been this catalog inventing
  a restriction and attributing it to RSGB\, which is the one thing it must
  not do.\n\nRSGB DOES PUBLISH THE LIST -- at hf/information/codes.shtml\, 
 linked from the rules page. The 151 prefixes here are read from that page 
 and are RSGB's own\, not a reconstruction. The lesson generalises: the blo
 cker was a link nobody had followed.\n\nTHE LIST IS PREFIXES\, NOT DXCC EN
 TITIES\, and they are not the same thing. RSGB splits Canada into VE1-VE9\
 , Australia into VK0-VK9\, New Zealand into ZL0-ZL9 and South Africa into 
 ZS0-ZS8\, because a 'call area' is the multiplier and there are several pe
 r country. It also treats England\, Scotland\, Wales\, Northern Ireland\, 
 Jersey\, Guernsey and the Isle of Man as seven separate areas whose contac
 ts with each other score nothing.\n\nA K STATION CANNOT ENTER\, and the pa
 ge now says so in a sentence rather than a paragraph: listing 151 prefixes
  inline produced a wall of text instead of an answer\, so eligibility_for 
 summarises any list longer than eight.\nRules: https://www.rsgbcc.org/hf/r

 6 14/15 -- eight years\, all reproduced. 2020 is the year that discriminat
 es: 1 March 2020 was a Sunday\, so counting weekends by their Sunday gives
  7/8\, but SRS published 14/15. The log deadline is a stated instant (19 M
 arch 2026\, 23:59 UTC) rather than an interval from the contest end\, so i
 t is recorded here. BLOCKERS: yudx.org\, the host in the registry\, no lon
 ger resolves\; SRS's own domestic schedule and rules pages ('Raspored takm
 icenja i pravila'\, 'Takmicenja') render only a JavaScript placeholder\, a

DESCRIPTION:Sponsor: SARL\nModes: SSB\, CW\, RTTY\nBands: 20m\nBand note: C
 W 14 000-14 060 kHz\; SSB 14 125-14 300 kHz\; RTTY 14 080-14 099 kHz.\nDur
 ation: 1h\nExchange: Your name\, your Abbreviated Club Callsign and your 4
 -character grid square (for example KG30).\nEligibility: Entry limited to 
 ZS. K stations may be worked but cannot submit an entry.\nNote: A club cha
 mpionship rather than an individual contest: operators' scores are added i
 nto a club total. The month list is SARL's own -- these run in four months
  of the year\, not every month -- which is what monthly_nth_weekday's `mon
 ths` field exists for. log_format and log_deadline_days are absent: this p
 ass read each contest's Aim\, Dates\, Frequencies and Exchange sections an
 d did not read its Log Sheets section\, so neither is recorded rather than
  assumed from SARL's other contests.\n\nPROVENANCE RESTORED 2026-08-23. Th
 is record carried verified: true with an EMPTY source_note -- one of three
  the 2026-08-21 rule audit found\, and a stricter defect than the thin ARR
 L notes beside them: an empty string is not weak evidence\, it is none\, a
 nd there was nothing in the record to check a rule against. The rule\, the
  times\, the bands and the exchange were all correct\; only the evidence f
 or them was missing. Re-read from the manual and quoted above\, and SARL's
  own printed 2026 dates reproduce it.\nRules: https://mysarl.org.za/wp-con

SUMMARY:Russian DX Contest (RDXC)
DESCRIPTION:Sponsor: SRR\nModes: CW\, SSB\nBands: 160m\, 80m\, 40m\, 20m\, 
 15m\, 10m\nBand note: 1.8-28 MHz\, WARC bands excluded.\nDuration: 23h 59m
 \nExchange: Russian stations send RS(T) and their two-letter oblast identi
 fier\; everyone else sends RS(T) and a serial from 001\, numbered continuo
 usly across bands.\nLogs due: 2027-04-04\nNote: SRR's rules page states a 
 date and no recurrence rule\, so the record is manual -- and the only year
  it states is 2027\, which is why this contest produces no 2026 occurrence
 . Inferring 'the fourth full weekend of March' from one printed date would
  be this catalog writing a rule SRR did not. The 14-day deadline is checka
 ble against SRR's own arithmetic: the contest ends 11:59 UTC on 21 March 2
 027 and SRR prints 4 April 2027 as the last day\, which is exactly 14 days
 . CONTRADICTION\, recorded not reconciled: the rules say the contest ends 
 at 11:59 UTC while the site banner says '12:00-12:00 UTC'. The rules text 
 is what is encoded.\nRules: https://www.rdxc.org/rules

  be worth stating. log_format and log_deadline_days are absent: this pass

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-04-08\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 il one -- the seasons are southern hemisphere\, so January is summer. One 
 of SARL's four named QRP legs. They are four records rather than one becau
 se SARL names four legs by season and they do not share a clock: the Summe
 r and Winter legs run 07:00-09:00 UTC and the Autumn and Spring legs 13:30
 -15:30\, so no single start/end pair covers them. Grouping the two pairs b

  not use. log_format and log_deadline_days are absent: this pass read each

 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are

  seven-day interval but 23:59 rather than the 11:59 that end-plus-7-days g

 NG DIFFERENCE\, RECORDED RATHER THAN RECONCILED: the SSB rules say 'second
  weekend in April' where the CW rules say 'Second (full) weekend in Novemb
 er'. The two readings cannot diverge at n = 2 -- the second Saturday of a 
 month is at most the 14th\, so its Sunday is always in the same month -- s
 o no choice between them was needed. BLOCKER RECORDED\, NOT WORKED AROUND:
  okomdx.crk.cz serves a TLS certificate issued for default.web4u.cz\, so H
 TTPS fails validation and the rules are reachable only over plain HTTP. ru
 les_url is therefore http:// deliberately\; it is not an oversight\, and t

 MHz. The phone all-band category excludes 14 MHz\; CW may use it. JARL's 
 電話 covers AM\, SSB and FM\, and 電信 is CW.\nDuration: 24h\nExchange
 : RST\, the prefecture or region number for where you are operating\, and 
 one letter for power -- H above 100 W\, M to 100 W\, L to 10 W (20 W on 50
  MHz)\, P at 5 W or less. Tokyo at 10 watts on phone sends 5910L.\nEligibi
 lity: Entry limited to JA. K stations may be worked but cannot submit an e
 ntry.\nNote: The rule is anchored on the LAST SUNDAY and counts backwards 
 to the Saturday\, which is how JARL writes it. Checked rather than assumed
 : that is the same date as 'the last full weekend of April' in every year\
 , and always will be -- April's last Sunday falls on the 24th at the earli
 est\, so the Saturday before it is never outside the month. JARL's wording
  is encoded because it is JARL's\, not because it changes an answer. Contr
 ast ACAG\, where the equivalent choice moves the contest a full week in 20
 28 and 2029. Encoded as wall_clock in Asia/Tokyo because that is how JARL 
 states it -- 21時00分（JST） -- rather than converted to a fixed UTC t
 ime by hand. Japan has not observed daylight saving since 1952\, so the tw
 o are identical in practice and will stay so\; the record says what the sp
 onsor said and lets the engine do the arithmetic. log_deadline_days is abs
 ent. JARL prints a dated deadline above the rules for the edition in hand 
 -- ALL JA 2026 is '提出締切日 2026年5月6日（水）必着' -- and 
 the numbered 規約 clauses that follow state the dates\, eligibility\, ba
 nds\, categories and exchange but no submission span. All four of JARL's 2
 026 deadlines happen to fall exactly ten days after their contest ends\, w
 hich is suggestive and is not a rule JARL wrote. The same reasoning alread
 y keeps a deadline off JARL's All Asian records.\nRules: https://www.jarl.

 24 Apr 2027\; SSB on 1 Nov 2025\, 31 Oct 2026 and 23 Oct 2027.\n\nThe CW d
 ates happen to be the last Saturday of April in all three years. The SSB d
 ates fit nothing at all -- the FIRST Saturday of November\, then the FIFTH
  Saturday of October\, then the FOURTH -- not even the same month twice ru
 nning. So this organiser demonstrably does not schedule by ordinal\, which
  is the strongest possible argument against fitting one to the CW leg beca
 use three years happen to agree. Both legs hold exactly the dates UKEICC p
 rinted and produce nothing for 2028 until it publishes them.\n\nFOUND THRO
 UGH RSGB'S HF CHAMPIONSHIP TABLE\, which lists the eleven contests that co
 unt towards it. That page is an award over other contests rather than a co
 ntest itself -- the same call already made about the WIA Contest Champion 
 -- but it is an excellent index of what RSGB's season actually contains\,

  for. log_format and log_deadline_days are absent: this pass read each con

 resented as one. Confirm the session length with the ZMC manager before sh

 put\nNote: CORRECTION (anchor): previously encoded as the first TUESDAY of
  the month. The sponsor's rule is the first MONDAY US local\, which lands 
 on Tuesday UTC -- and those are different dates whenever the 1st falls on 
 a Tuesday (Sep and Dec 2026). SPONSOR-ANCHORED LOCAL TIME: ARS publishes n
 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n
 ot\, is the one place the sponsor's own table is inconsistent.\nRules: htt

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-05-13\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 g sheets -- and names its organising club\, rather than summarising a cale
 ndar entry. It is the venue in which South African clubs publish their con
 test rules\, the way DARC's Ausschreibungen or UBA's rules pages are\, so 
 it is a primary source for these contests and not a third-party listing. T
 he distinction that matters: an aggregator republishes rules it found else
 where\, and this is where the rules appear.\nRules: https://mysarl.org.za/

DESCRIPTION:Sponsor: SOTA SA\nModes: Mixed\nBands: not yet read off the spo
 nsor's own rules\nDuration: 45h 59m\nExchange: An RS\, RST or RSQ report a
 nd the SOTA reference.\nNote: THE CATALOG'S SECOND RECORD WITH NO BANDS\, 
 AND THE SECOND FOR A GOOD REASON. SARL states '2. Frequencies and modes Al
 l amateur bands and modes' -- there is no list to record\, and writing one
  out would be this catalog inventing a restriction SARL did not state. Sam
 e treatment as JARL's New Year QSO Party. The consequence is real and the 
 page says so: every band filter necessarily excludes this record.\n\nModes
  are 'Mixed' for the same sentence -- that is exactly what the token means
 .\n\nIt sits at the edge of what this catalog is for. It has dates\, rules
 \, an exchange and categories\, so it is a scheduled operating event with 
 a schedule worth publishing\; but it is scored through the SOTA database r
 ather than by a log submitted to the sponsor\, and 'Activator' and 'Chaser
 ' are roles rather than entry classes. Encoded on the same reasoning as UB
 A's Belgian Mills Award\, which is also an award-shaped event with real da
 tes. Sourced from the SARL Contest Manual\, which carries this contest's f
 ull rules and names its organising body -- the venue in which South Africa
 n clubs publish their rules\, not a listing of them. See data/sources.md\,

SUMMARY:DARC HELL-Kurzcontest (unverified)
DESCRIPTION:Sponsor: DARC\nModes: Digital (Hell)\nBands: not yet read off t
 he sponsor's own rules\nDuration: 59m\nExchange: not recorded yet — see 
 the sponsor's rules below\nNote: VERIFIED FALSE\, AND THE RECURRENCE IS ST
 ILL DERIVED FROM DARC'S OWN FOUR DATES. All four are the THIRD TUESDAY of 
 the second month of each quarter -- 17 Feb\, 19 May\, 18 Aug\, 17 Nov 2026
  -- which is a clean pattern across four points and sits alongside the RTT
 Y-Kurzcontest (2nd Tuesday\, months 1/4/7/10) and the FT4 Contest (2nd Tue
 sday\, months 2/5/8/11) that DARC already runs.\n\nWhat is missing is ever
 ything the rules page would give: BANDS ARE UNRECORDED\, so every band fil
 ter excludes this record\, and the exchange and deadline are absent. The m
 ode is taken from the contest's own name. That is why it is unverified: th
 e dates are DARC's\, the rule is an inference from them\, and the rest is 
 a gap.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not read: this series has no Au
 sschreibung linked from DARC's table. That sentence sits here rather than 
 in bands_note\, because bands_note is for a sponsor's own wording ABOUT a 
 band list and must never stand in for one -- a test enforces it\, and it c
 aught this.\nUNVERIFIED: these dates have not yet been checked against the
  sponsor's own published rules. Confirm before you rely on them.\nRules: h

 ge: Your name\, your Abbreviated Club Callsign and your 4-character grid s
 quare (for example KG30).\nEligibility: Entry limited to ZS. K stations ma
 y be worked but cannot submit an entry.\nNote: A club championship rather 
 than an individual contest: operators' scores are added into a club total.
  The month list is SARL's own -- these run in four months of the year\, no
 t every month -- which is what monthly_nth_weekday's `months` field exists
  for. log_format and log_deadline_days are absent: this pass read each con
 test's Aim\, Dates\, Frequencies and Exchange sections and did not read it
 s Log Sheets section\, so neither is recorded rather than assumed from SAR
 L's other contests.\n\nPROVENANCE RESTORED 2026-08-23. This record carried
  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th
 em: an empty string is not weak evidence\, it is none\, and there was noth
 ing in the record to check a rule against. The rule\, the times\, the band
 s and the exchange were all correct\; only the evidence for them was missi
 ng. Re-read from the manual and quoted above\, and SARL's own printed 2026

DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-06-10\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 ogs and separate results -- which is why both are here rather than one.\n\
 nThe pairing also settles what the IARU Region 1 Field Day IS: a framework
  each member society runs its own contest inside\, not a contest IARU publ
 ishes rules for. DARC lists it on their calendar and says it is IARU's\; U
 BA lists it too\; IARU Region 1's own site publishes rules for the HF Cham
 pionship and nothing else. Nobody claims it\, so there is nothing to encod
 e under IARU's name.\n\nENTRY IS EI ONLY AND PORTABLE ONLY: 'Any individua
 l or group operating in EI complying with Rule 3.6 of the General Rules an
 d operating portable on a site'. Stations elsewhere may be worked but cann
 ot enter.\nRules: https://www.irts.ie/cgi/st.cgi?r_hffdrules.html

  G. K stations may be worked but cannot submit an entry.\nNote: 2024 IS TH
 E YEAR THAT SETTLES THE RULE. 1 June 2024 was itself a Saturday and RSGB u
 sed it\, so this contest has NO first-of-the-month exception -- unlike the
  RSGB AFS contests\, where 1 January 2022 was a Saturday and the contest m
 oved a week. Two contests from the same committee\, two different answers\
 , and only the published dates distinguish them. RSGB keeps a rules page p
 er year\, so its own dates check its own rule. Four years were read for th
 is record -- 2023\, 2024\, 2025 and 2026 -- and the recurrence reproduces 
 all of them.\nRules: https://www.rsgbcc.org/hf/rules/2027/rnfd.shtml

 on Tuesday UTC -- and those are different dates whenever the 1st falls on 
 a Tuesday (Sep and Dec 2026). SPONSOR-ANCHORED LOCAL TIME: ARS publishes n
 o UTC time and states the event 'is always at these Local Times'\, so the 
 UTC instant is what moves -- 0100Z Tuesday under EST\, 0000Z Tuesday under
  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are
  the same instant in every zone that observes DST\; Arizona\, which does n

DESCRIPTION:Sponsor: DARC\nModes: CW\nBands: not yet read off the sponsor's
  own rules\nDuration: 59m\nExchange: not recorded yet — see the sponsor'
 s rules below\nNote: IT COMPLETES A PATTERN DARC DESCRIBES BUT DOES NOT SP
 ELL OUT. Their three short contests take one month of each quarter in turn
 \, all on a Tuesday evening: the RTTY-Kurzcontest in months 1/4/7/10\, the
  FT4 Contest in 2/5/8/11\, and this one in 3/6/9/12. All four of DARC's pu
 blished dates are the SECOND TUESDAY of those months. That is what 'reiht 
 sich vom Termin her in die anderen ... ein' means\, and the arithmetic con
 firms it rather than assuming it.\n\nVERIFIED FALSE because the page that 
 describes the series is prose about teaching CW rather than an Ausschreibu
 ng: no bands\, no exchange\, no deadline. BANDS ARE UNRECORDED\, so every 
 band filter excludes this record.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not 
 stated on the page that describes the series. That sentence sits here rath
 er than in bands_note\, because bands_note is for a sponsor's own wording 
 ABOUT a band list and must never stand in for one -- a test enforces it\, 
 and it caught this.\nUNVERIFIED: these dates have not yet been checked aga
 inst the sponsor's own published rules. Confirm before you rely on them.\n

 44MHz\; 4m=70 MHz\; 70cm=432MHz\; 23cm=1200MHz e 13cm=2300 MHz) -- the IAR
 U Region 1 band plans. REP's list includes 4m (70 MHz)\, which is not in t

 rep.pt\, the portal linked from rep.pt's own front page\, says 10 June eve
 ry year\, lists 2m/4m/70cm/23cm/13cm\, weights points per band and sets th
 e log deadline at 20 June. portugaldaycontest.rep.pt/regras_vhf_uhf.php st
 ill says 'no 2º Sábado do mês de junho de cada ano\, (8 de Junho de 202
 4)'\, lists only 2m/70cm/23cm\, and sets the deadline at 30 June. The two 
 disagree about the date in every year where 10 June is not the second Satu
 rday. The fixed date is encoded because it is the one REP actually ran: 10
  June 2025 was a Tuesday and REP's logs-received post for the 2025 running
  is dated that day\, whereas the second Saturday of June 2025 was the 14th
 . The superseded page is recorded here rather than silently ignored. Becau
 se both the contest and the deadline are fixed dates\, log_deadline_days i
 s exactly 10 in every year -- unlike REP's two other contests\, whose dead
 lines are calendar dates that do not sit a constant span after the contest
 . Modes: REP writes 'Fonia' (phone) rather than SSB specifically\; SSB is 
 the catalog's only phone token.\nRules: https://concursos.rep.pt/concurso-

  Entry limited to ZS\, V5\, A2\, Z2\, C9\, 7P\, 3DA. K stations may be wor
 ked but cannot submit an entry.\nNote: THE RECORD THAT PUT FM IN THE MODE 
 VOCABULARY. This contest is FM ONLY\, and until 2026-08-19 this catalog ha
 d no FM token -- it used SSB as a general phone token\, which was servicea
 ble while every phone contest also allowed SSB. Recording an FM-only conte
 st as SSB would have stated something SARL does not permit\, which is prec
 isely the overstatement the mode rules exist to prevent\, so FM was added 
 to CATALOG_MODES in both engines and to the filter families instead. Ten r
 ecords that had been carrying FM in submodes moved it into modes in the sa
 me commit.\n\nTwo legs on one record: both run 10:00-13:00 UTC and differ 
 only in their anchor\, and the anchors are different SHAPES -- the second 
 Saturday of June and the LAST Saturday of October -- which a composite hol
 ds without trouble.\n\nSARL explains the timing: 'The dates are three week
 s after the RAE Radio Amateur Examination'\, which is why the contest is a
 imed at newly licensed amateurs. That is context rather than a rule\; the 
 ordinals are what is encoded.\n\nNo log deadline was read in this pass\, s

SUMMARY:Portugal Day Contest (HF)
DESCRIPTION:Sponsor: REP\nModes: SSB\, CW\nBands: 80m\, 40m\, 20m\, 15m\, 1
 0m\nBand note: 10\, 15\, 20\, 40 and 80 meter bands\, fully respecting lic
 ensing rules of each country. Observance of established band plans is stro
 ngly encouraged.\nDuration: 23h 59m\nExchange: DX stations send RST and a 
 sequential number beginning 001\; Portuguese stations\, including the Azor
 es and Madeira\, send RST and the letters identifying their district (or c
 ounty in the Azores and Madeira).\nNote: log_deadline_days is deliberately
  absent. REP states a fixed calendar deadline -- 'no later than June 30th 
 of the same year' -- not a span\, and June 30 is 15 days after the 2025 ru
 nning but 16 after the 2026 one\, so any single number would be wrong in m
 ost years. REP's 2030 date is what pins the recurrence\, and it rules out 
 the reading that would otherwise be tempting: 1 June 2030 is itself a Satu
 rday\, so a reader who did not count a weekend opening on the 1st would ma
 ke 8-9 June the first and 15-16 the second. REP publishes 8-9 June\, so th
 e weekend opening on the 1st counts. Nothing turns on full weekend versus 
 second Saturday here -- the two readings give the same date in every year 
 from 2025 to 2060\, because only a Saturday falling on a month's LAST day 
 fails to open a full weekend\, which a second Saturday never is. The full-
 weekend type is encoded because 'fim de semana' is REP's own wording\, not
  because it changes an answer. 'Mixed' is one of REP's three entry categor
 ies rather than a fourth mode -- the contest permits SSB and CW\, which is
  what modes records. Logs go to rep-concursos@rep.pt by e-mail\; there is 
 no submission website\, so log_submit_url is absent.\nRules: https://concu

 xchange: French metropolitan stations send RS(T) + department + a six-char
 acter locator (e.g. 59 75 JN18DU)\; all other stations send RS(T) + serial
  number + locator (e.g. 59 001 KN04FG).\nLogs due: 2027-06-16\nNote: FM is
  recorded as a submode because the catalog's mode vocabulary has no FM tok
 en\; REF lists 'SSB\, CW\, FM' as the permitted modes and all three are wo
 rked on the same 6 m band. log_deadline_days is derived from 'le premier m
 ercredi qui suit le concours': the contest ends 1400 UTC Sunday and the fo
 llowing Wednesday is exactly three days later\, in every year. CONTRADICTI
 ON RECORDED RATHER THAN RECONCILED: REF's 2025 contest calendar listed thi
 s contest with a 15:00 start\, while this rules PDF and REF's 2026 calenda
 r both say 14:00. The rules are encoded. Separately\, REF's 2026 calendar 
 prints the 'Coupe du REF - OM complet' row with its end before its start (
 27/06/2026 06:00 to 07/06/2026 14:00)\; no record here depends on it.\nRul

  contest rules\, the way DARC's Ausschreibungen or UBA's rules pages are\,

 is record carried verified: true with an EMPTY source_note -- one of three
  the 2026-08-21 rule audit found\, and a stricter defect than the thin ARR

DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 35h 
 59m\nExchange: RST\, QTH\, the operator's name\, a four-character grid squ
 are and the SKCC number. Non-members send 'none' for the number.\nLogs due
 : 2027-06-28\nNote: THIRTY-SIX HOURS\, NOT A WEEKEND: 1200 UTC Saturday to
  2359 UTC Sunday\, so it starts at midday and runs to the end of the secon
 d day.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no keyboar
 d. That is the club's whole premise rather than a category.\n\nThe log dea
 dline is eight days because SKCC states it as a WEEKDAY rather than an int
 erval -- 'the Sunday following the event' -- and the contest ends on a Sun
 day\, so the next Sunday is eight days after the Saturday it started.\nRul

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-07-08\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

SUMMARY:6m AND DOWN Contest
DESCRIPTION:Sponsor: JARL\nModes: CW\, SSB\, FM (AM)\nBands: 6m\, 2m\, 70cm
 \, 23cm\, 13cm\, 3cm\nBand note: 50\, 144 and 430 MHz plus every amateur b
 and at 1200 MHz and above -- JARL's categories run 1200\, 2400 and 5600 MH
 z and 10.1 GHz and up. The 5600 MHz band has no token in this catalog's ba
 nd vocabulary and is recorded only here.\nDuration: 18h\nExchange: On 50 M
 Hz to 1200 MHz: RST\, the prefecture or region number\, and the power lett
 er. On 2400 MHz and above: RST\, the city\, county or ward number\, and th
 e power letter.\nEligibility: Entry limited to JA. K stations may be worke
 d but cannot submit an entry.\nNote: Eighteen hours\, not a full day: it o
 pens at 2100 and closes at 1500\, so the overnight VHF opening is the poin
 t of it. Encoded as wall_clock in Asia/Tokyo because that is how JARL stat
 es it -- 21時00分（JST） -- rather than converted to a fixed UTC time 
 by hand. Japan has not observed daylight saving since 1952\, so the two ar
 e identical in practice and will stay so\; the record says what the sponso
 r said and lets the engine do the arithmetic. log_deadline_days is absent.
  JARL prints a dated deadline above the rules for the edition in hand -- A
 LL JA 2026 is '提出締切日 2026年5月6日（水）必着' -- and the 
 numbered 規約 clauses that follow state the dates\, eligibility\, bands\
 , categories and exchange but no submission span. All four of JARL's 2026 
 deadlines happen to fall exactly ten days after their contest ends\, which
  is suggestive and is not a rule JARL wrote. The same reasoning already ke
 eps a deadline off JARL's All Asian records.\nRules: https://www.jarl.org/

SUMMARY:TA VHF-UHF Contest (unverified)
DESCRIPTION:Sponsor: TRAC\nModes: SSB\, CW\, FM\nBands: 6m\, 2m\, 70cm\nBan
 d note: 6m: 50-52 MHz\, 2m: 144-146 MHz\, 70cm: 430-440 MHz\, per the IARU
  Region 1 band plan. Phone is SSB or FM. Digital modes such as FT8 and JT6
 5 and digital radios such as DMR and C4FM are forbidden -- 'Tüm QSO'lar a
 nalog olmalıdır'\, all QSOs must be analogue.\nDuration: 24h\nExchange: 
 RST\, a serial number starting at 001\, and a six-character Maidenhead loc
 ator -- for example '59 123 KN90UX'.\nNote: VERIFIED FALSE\, AND THE EXCEP
 TION IS THIS CATALOG'S INFERENCE RATHER THAN TRAC'S WORDING.\n\nTRAC state
 s 'Temmuz ayının ilk hafta sonu' -- the first weekend of July -- and tha
 t reproduces its own published dates for 2024\, 2025 and 2026. It does NOT
  reproduce 2023: 1 July 2023 was itself a Saturday\, so the rule gives 1-2
  July\, and TRAC ran the contest on 8-9 July\, a week later.\n\n`exclude_d
 ates: [[7\, 1]]` is what makes all FOUR published dates come out right\, a
 nd it is the same shape as ARRL RTTY Roundup's 'first full weekend of Janu
 ary but never 1 January'. The difference is that ARRL states its exception
  and TRAC does not\, so this is one year's evidence fitted into a rule rat
 her than a rule read off a page.\n\nIt only matters when 1 July is a Satur
 day\, which next happens in 2028\, then 2034 and 2045. In every other year
  the exception is inert and the record is simply TRAC's own sentence. Ask 
 TRAC what happens when the month opens on a Saturday and this becomes veri
 fied either way.\n\nModes: TRAC permits SSB\, CW and FM. SSB is this catal
 og's only phone token\, so FM is recorded in submodes and the ban on digit
 al modes is in bands_note.\nUNVERIFIED: these dates have not yet been chec
 ked against the sponsor's own published rules. Confirm before you rely on 
 them.\nRules: https://trac.org.tr/tr/ta-vhf-uhf-contest-2026

  EDT. Resolved through America/New_York rather than hardcoded\, so DST is 
 handled. ARS lists Eastern\, Central\, Mountain and Pacific times that are

 y one -- the seasons are southern hemisphere\, so January is summer. One o
 f SARL's four named QRP legs. They are four records rather than one becaus
 e SARL names four legs by season and they do not share a clock: the Summer
  and Winter legs run 07:00-09:00 UTC and the Autumn and Spring legs 13:30-
 15:30\, so no single start/end pair covers them. Grouping the two pairs by
  their times would have been this catalog inventing a structure SARL does 
 not use. log_format and log_deadline_days are absent: this pass read each 
 contest's Aim\, Dates\, Frequencies and Exchange sections and did not read
  its Log Sheets section\, so neither is recorded rather than assumed from 
 SARL's other contests.\nRules: https://mysarl.org.za/wp-content/uploads/20

 nDuration: 3h\nExchange: RS(T) plus a serial number starting at 1 and incr

 OUR'S BREAK FOR LUNCH\, which is why this record uses the sessions array: 
 0900-1200 and 1300-1600. Encoding it as a single seven-hour block would pu
 t a contest on the calendar during an hour RSGB does not run one.\n\nThe e
 xchange includes your transmitted power\, which is how a low-power contest
  scores itself.\n\nELIGIBILITY IS THE ONE UNVERIFIED THING HERE. RSGB says
  'UK&CD entrants must be RSGB members' and says nothing about anyone else\
 , which reads as open but is an absence rather than a statement. RSGB also
  runs a separately-named 'International Low Power Contest' in its results 
 archive\, which suggests this one may be the domestic one. Worth one quest
 ion. RSGB keeps a rules page per year\, so its own dates check its own rul
 e. Four years were read for this record -- 2023\, 2024\, 2025 and 2026 -- 
 and the recurrence reproduces all of them.\n\nPART OF THIS IS NOW ANSWERED
 \, 2026-08-23. The open question was whether the July contest encoded here
  is RSGB's domestic low-power event or the 'International Low Power Contes
 t' that appears separately in their results archive. RSGB's own HF Champio
 nship page lists the eleven contests counting towards it\, and the July en
 try is named 'International Low Power Contest' -- there is exactly one low
 -power contest in RSGB's season and it is this one. So the two names are t
 he same contest.\n\nThat does NOT by itself prove non-UK stations may ente
 r\, which is why the record stays verified: false: the championship's own 
 entry clause is 'single operators who at the time of each contest are RSGB
  members and are operating in the UK&CD'\, and that is the CHAMPIONSHIP's 
 restriction rather than the contest's. What has gone is the possibility th
 at we encoded the wrong one of two contests.\nRules: https://www.rsgbcc.or

  is RSGB's domestic low-power event or the 'International Low Power Contes
 t' that appears separately in their results archive. RSGB's own HF Champio
 nship page lists the eleven contests counting towards it\, and the July en
 try is named 'International Low Power Contest' -- there is exactly one low
 -power contest in RSGB's season and it is this one. So the two names are t
 he same contest.\n\nThat does NOT by itself prove non-UK stations may ente
 r\, which is why the record stays verified: false: the championship's own 
 entry clause is 'single operators who at the time of each contest are RSGB
  members and are operating in the UK&CD'\, and that is the CHAMPIONSHIP's 
 restriction rather than the contest's. What has gone is the possibility th
 at we encoded the wrong one of two contests.\nRules: https://www.rsgbcc.or

 than an individual contest: operators' scores are added into a club total.
  The month list is SARL's own -- these run in four months of the year\, no
 t every month -- which is what monthly_nth_weekday's `months` field exists
  for. log_format and log_deadline_days are absent: this pass read each con
 test's Aim\, Dates\, Frequencies and Exchange sections and did not read it

 L's other contests.\n\nPROVENANCE RESTORED 2026-08-23. This record carried
  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th

 s and the exchange were all correct\; only the evidence for them was missi
 ng. Re-read from the manual and quoted above\, and SARL's own printed 2026

 arting at 001.\nLogs due: 2027-08-06\nNote: PREVIOUSLY UNVERIFIED\, AND TH
 E FLAG WAS DOING ITS JOB. This record was carried with bands: [] and eligi
 bility guessed as ZS-only 'Confirm'\, because sarl.org.za served an expire
 d certificate. SARL has since moved to mysarl.org.za and the rules are now
  readable: the recurrence and times the record already held were right\, t
 he bands are 20/40/80 m\, and the eligibility guess was WRONG -- the scori
 ng table's Area 9 is 'Stations in the rest of the world'. log_deadline_day
 s is 5\, which is the right DAY and not the right hour: SARL states 'by 21
 :59 UTC on Friday'\, and the contest ends at 17:00 UTC on the Sunday five 
 days before\, so the engine's derived log_due lands at 17:00 rather than 2
 1:59. The day is exact in every year because both ends are tied to the sam
 e Sunday. The five hours are recorded here rather than papered over.\nRule

DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-08-12\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 ories exclude 14 MHz.\nDuration: 18h\nExchange: On 1.9 MHz to 1200 MHz: RS
 T\, the prefecture or region number\, and the power letter. On 2400 MHz an
 d above: RST\, the city\, county or ward number\, and the power letter.\nE
 ligibility: Entry limited to JA. K stations may be worked but cannot submi
 t an entry.\nNote: Same eighteen-hour shape as 6m AND DOWN a month earlier
 \, and on all bands rather than VHF up. Encoded as wall_clock in Asia/Toky
 o because that is how JARL states it -- 21時00分（JST） -- rather than
  converted to a fixed UTC time by hand. Japan has not observed daylight sa
 ving since 1952\, so the two are identical in practice and will stay so\; 
 the record says what the sponsor said and lets the engine do the arithmeti
 c. log_deadline_days is absent. JARL prints a dated deadline above the rul
 es for the edition in hand -- ALL JA 2026 is '提出締切日 2026年5月6
 日（水）必着' -- and the numbered 規約 clauses that follow state t
 he dates\, eligibility\, bands\, categories and exchange but no submission
  span. All four of JARL's 2026 deadlines happen to fall exactly ten days a
 fter their contest ends\, which is suggestive and is not a rule JARL wrote
 . The same reasoning already keeps a deadline off JARL's All Asian records

 6 m (50 MHz)\, de acordo com os planos de frequência recomendados pela IA
 RU para cada região -- 6m per the IARU band plans for each region.\nDurat
 ion: 24h\nExchange: RS(T)\, a sequential QSO number beginning 001 and the 
 QTH locator of both stations (for example IM58is). The contact time need n
 ot be exchanged but must be logged in UTC.\nNote: REP writes 'fim de seman
 a completo' -- complete weekend -- which is exactly the distinction this e
 ngine models: a Saturday/Sunday pair with both days inside the month. It i
 s encoded because it is REP's wording\, NOT because it changes a date: che
 cked rather than assumed\, the full-weekend and first-Saturday readings ag
 ree for the first weekend of August in every year from 2025 to 2060\, beca
 use the only Saturday that can fail to open a full weekend is one falling 
 on the month's last day. The distinction bites on 'last weekend' rules\, n
 ot on this one. log_deadline_days is absent because REP states a dated dea
 dline for the edition ('até às 23:59 (UTC) do dia 8 de Agosto de 2025') 
 rather than a span\, and 8 August is 5 days after the 2025 running but wou
 ld be 6 after the 2026 one. Modes: REP allows phone as AM\, SSB or FM\; SS
 B is the catalog's only phone token\, so AM and FM are recorded in submode
 s. REP has published no 2026 edition on concursos.rep.pt as of 2026-08-19\
 , and the first full weekend of August 2026 has passed\; the rule is encod
 ed as REP states it and no suspension is inferred from a missing post.\nRu

 legs -- 13:00 UTC\, not 14:00 -- which is SARL's own wording and not a tra

 he right hour: SARL states 'by 21:59 UTC on Friday'\, and the contest ends
  at 17:00 UTC on the Sunday five days before\, so the engine's derived log
 _due lands at 17:00 rather than 21:59. The day is exact in every year beca

 5 days exactly. The engine applies log_deadline_days to each session separ
 ately\, so the first session's computed deadline falls a day before URE's 
 printed one. Dropping the interval to quote a fixed date instead would los

SUMMARY:DARC HELL-Kurzcontest (unverified)
DESCRIPTION:Sponsor: DARC\nModes: Digital (Hell)\nBands: not yet read off t
 he sponsor's own rules\nDuration: 59m\nExchange: not recorded yet — see 
 the sponsor's rules below\nNote: VERIFIED FALSE\, AND THE RECURRENCE IS ST
 ILL DERIVED FROM DARC'S OWN FOUR DATES. All four are the THIRD TUESDAY of 
 the second month of each quarter -- 17 Feb\, 19 May\, 18 Aug\, 17 Nov 2026
  -- which is a clean pattern across four points and sits alongside the RTT
 Y-Kurzcontest (2nd Tuesday\, months 1/4/7/10) and the FT4 Contest (2nd Tue
 sday\, months 2/5/8/11) that DARC already runs.\n\nWhat is missing is ever
 ything the rules page would give: BANDS ARE UNRECORDED\, so every band fil
 ter excludes this record\, and the exchange and deadline are absent. The m
 ode is taken from the contest's own name. That is why it is unverified: th
 e dates are DARC's\, the rule is an inference from them\, and the rest is 
 a gap.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not read: this series has no Au
 sschreibung linked from DARC's table. That sentence sits here rather than 
 in bands_note\, because bands_note is for a sponsor's own wording ABOUT a 
 band list and must never stand in for one -- a test enforces it\, and it c
 aught this.\nUNVERIFIED: these dates have not yet been checked against the
  sponsor's own published rules. Confirm before you rely on them.\nRules: h

 than an individual contest: operators' scores are added into a club total.
  The month list is SARL's own -- these run in four months of the year\, no
 t every month -- which is what monthly_nth_weekday's `months` field exists
  for. log_format and log_deadline_days are absent: this pass read each con

  verified: true with an EMPTY source_note -- one of three the 2026-08-21 r
 ule audit found\, and a stricter defect than the thin ARRL notes beside th
 em: an empty string is not weak evidence\, it is none\, and there was noth

 ng. Re-read from the manual and quoted above\, and SARL's own printed 2026

 five-Sunday August the two differ\, and SARL writes '(4th Sunday)'. log_de
 adline_days is 5\, which is the right DAY and not the right hour: SARL sta
 tes 'by 21:59 UTC on Friday'\, and the contest ends at 17:00 UTC on the Su
 nday five days before\, so the engine's derived log_due lands at 17:00 rat
 her than 21:59. The day is exact in every year because both ends are tied 
 to the same Sunday. The five hours are recorded here rather than papered o

SUMMARY:World Wide Digi DX Contest
DESCRIPTION:Sponsor: WWROF / Slovenia Contest Club\nModes: FT8/FT4 (FT4\, F
 T8)\nBands: 160m\, 80m\, 40m\, 20m\, 15m\, 10m\nBand note: Six bands only:
  1.8\, 3.5\, 7\, 14\, 21 and 28 MHz.\nDuration: 23h 59m\nExchange: A four-
 character Maidenhead grid square.\nLogs due: 2027-08-31\nNote: THE RECURRE
 NCE IS THE SPONSOR'S OWN WORDS AND IT SURVIVES THE YEAR THAT TESTS IT. 'La
 st full weekend of August' and 'last Saturday of August' are different rul
 es\, and they diverge whenever 31 August is a Saturday -- the Sunday then 
 falls in September\, so that weekend is not full. 2024 was such a year. Th
 e sponsor's own 2024 rules PDF (ww-digi.com/rules/wwdigi24_eng.pdf) reads 
 '2024 World Wide Digi DX Contest Starts: Saturday August 24 12:00:00 UTC E
 nds: Sunday August 25 11:59:59 UTC' -- the 24th\, not the 31st. So the ful
 l-weekend reading is what WWROF actually runs\, and nth_full_weekend with 
 n = -1 is right.\n\nChecked against five dates the sponsor published itsel
 f: 24 Aug 2024\, 29 Aug 2026\, 28 Aug 2027\, 26 Aug 2028 and 25 Aug 2029. 
 All five are reproduced.\n\nTHE LOG DEADLINE CHANGED FOR 2026\, from five 
 days to 48 hours. The 2024 rules said 'WITHIN FIVE (5) DAYS'\; the current
  rules say 'WITHIN 48 HOURS'. log_deadline_days is 2 and this note exists 
 so a reader comparing against an older edition is not misled.\n\nALSO NEW 
 AND WORTH READING BEFORE ENTERING: autonomous operation is prohibited. 'A 
 human operator must initiate calling each QSO partner. Autonomous systems 
 or robots that emulate this action are prohibited.' That is a rule about u
 nattended FT8\, which is how a lot of stations run this mode.\nRules: http

 0m\nBand note: 3.5-28 MHz\, WARC bands excluded.\nDuration: 23h 59m\nExcha
 nge: Stations outside Romania send RS(T) and a serial from 001\; YO statio
 ns send RS(T) and their county abbreviation.\nLogs due: 2027-09-05\nNote: 
 August 2026 is the year that separates the readings: 1 August is a Saturda
 y\, so the month has five full weekends (1-2\, 8-9\, 15-16\, 22-23\, 29-30
 ) and the fourth is 22-23 August while the last is 29-30. The organisers' 
 own 2026 announcement says 22-23\, which is the fourth. CONTRADICTION\, re
 corded not reconciled: an older FRR rules PDF on hamradio.ro says 'Ultimul
  weekend intreg al lunii August' (the LAST full weekend of August)\, which
  would give 29-30. The current yodx.ro rules and FRR's own 2026 announceme
 nt agree on the fourth\, so that is what is encoded. Observation: the Roma
 nian page leaks '[cite: 9]' markers into its text\, which suggests it was 
 assembled by a tool\; the wording still matches the English edition.\nRule

SUMMARY:SKCC Straight Key Sprint Europe (SKSE)
DESCRIPTION:Sponsor: Straight Key Century Club\nModes: CW\nBands: 160m\, 80
 m\, 40m\, 20m\, 15m\, 10m\, 6m\nBand note: 160 through 6 m excluding the W
 ARC bands -- SKCC names 60\, 30\, 17 and 12 m as excluded.\nDuration: 2h\n
 Exchange: RST\, QTH\, the operator's name and the SKCC number. Non-members
  send 'none' for the number.\nLogs due: 2027-09-09\nNote: SKCC PRINTS TWO 
 UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March
  and 1900Z from April to October are both 2100 in central Europe: CET is U
 TC+1 and CEST is UTC+2. So this is not a contest that changes its hour twi
 ce a year\, it is a contest at nine in the evening that Europe's clocks mo
 ve around\, and it is recorded the way the sponsor means it -- `timezone: 
 Europe/Berlin` with wall_clock times\, exactly as the ARS Spartan Sprint i
 s recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE M
 ONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March an
 d of October\, and the first Thursday of both months falls on the near sid
 e of the change: March is still CET and resolves to 2000Z\, April is CEST 
 and resolves to 1900Z\, October is still CEST at 1900Z\, November is CET a
 t 2000Z. All four match SKCC's own table\, which is what makes this one ru
 le rather than two.\n\nEncoding it as two records split by month -- winter
  and summer -- would have produced two entries with the same name and hidd
 en the reason. Encoding one UTC time would have been wrong for five months
  of the year.\n\nStraight keys\, sideswipers and bugs only: no keyer\, no 
 keyboard. That is the club's whole premise rather than a category.\n\nThe 
 fifteen-minute QRS extensions at each end are not in the window: they are 
 an invitation to slow operators rather than part of the scored period.\nRu

 ARL states both readings itself\, weekend AND date\, and both agree for 20
 26. log_deadline_days is 5\, which is the right DAY and not the right hour
 : SARL states 'by 21:59 UTC on Friday'\, and the contest ends at 10:00 UTC
  on the Sunday five days before\, so the engine's derived log_due lands at
  17:00 rather than 21:59. The day is exact in every year because both ends
  are tied to the same Sunday. The five hours are recorded here rather than
  papered over.\nRules: https://mysarl.org.za/wp-content/uploads/2025/11/20

 WEEKEND AS RSGB'S\, AND THAT IS NOT A COINCIDENCE. Both societies run thei
 r leg of the IARU Region 1 Field Day: RSGB's National Field Day is the fir
 st Saturday of June and IRTS's CW Field Day is the first full weekend\, an
 d the same pairing repeats in September. They are separate contests with s
 eparate rules\, separate logs and separate results -- which is why both ar
 e here rather than one.\n\nThe pairing also settles what the IARU Region 1
  Field Day IS: a framework each member society runs its own contest inside
 \, not a contest IARU publishes rules for. DARC lists it on their calendar
  and says it is IARU's\; UBA lists it too\; IARU Region 1's own site publi
 shes rules for the HF Championship and nothing else. Nobody claims it\, so
  there is nothing to encode under IARU's name.\n\nENTRY IS EI ONLY AND POR
 TABLE ONLY: 'Any individual or group operating in EI complying with Rule 3
 .6 of the General Rules and operating portable on a site'. Stations elsewh
 ere may be worked but cannot enter.\n\nTwo differences from the CW field d
 ay\, both IRTS's own and both matching RSGB's pair exactly: it starts at 1
 300 rather than 1500\, and it drops 160 m.\nRules: https://www.irts.ie/cgi

DESCRIPTION:Sponsor: DARC\nModes: CW\nBands: not yet read off the sponsor's
  own rules\nDuration: 59m\nExchange: not recorded yet — see the sponsor'
 s rules below\nNote: IT COMPLETES A PATTERN DARC DESCRIBES BUT DOES NOT SP
 ELL OUT. Their three short contests take one month of each quarter in turn
 \, all on a Tuesday evening: the RTTY-Kurzcontest in months 1/4/7/10\, the
  FT4 Contest in 2/5/8/11\, and this one in 3/6/9/12. All four of DARC's pu
 blished dates are the SECOND TUESDAY of those months. That is what 'reiht 
 sich vom Termin her in die anderen ... ein' means\, and the arithmetic con
 firms it rather than assuming it.\n\nVERIFIED FALSE because the page that 
 describes the series is prose about teaching CW rather than an Ausschreibu
 ng: no bands\, no exchange\, no deadline. BANDS ARE UNRECORDED\, so every 
 band filter excludes this record.\n\nWHERE THE BANDS WOULD HAVE BEEN: Not 
 stated on the page that describes the series. That sentence sits here rath
 er than in bands_note\, because bands_note is for a sponsor's own wording 
 ABOUT a band list and must never stand in for one -- a test enforces it\, 
 and it caught this.\nUNVERIFIED: these dates have not yet been checked aga
 inst the sponsor's own published rules. Confirm before you rely on them.\n

SUMMARY:ZS SOTA Activity Weekend
DESCRIPTION:Sponsor: SOTA SA\nModes: Mixed\nBands: not yet read off the spo
 nsor's own rules\nDuration: 45h 59m\nExchange: An RS\, RST or RSQ report a
 nd the SOTA reference.\nNote: THE CATALOG'S SECOND RECORD WITH NO BANDS\, 
 AND THE SECOND FOR A GOOD REASON. SARL states '2. Frequencies and modes Al
 l amateur bands and modes' -- there is no list to record\, and writing one
  out would be this catalog inventing a restriction SARL did not state. Sam
 e treatment as JARL's New Year QSO Party. The consequence is real and the 
 page says so: every band filter necessarily excludes this record.\n\nModes
  are 'Mixed' for the same sentence -- that is exactly what the token means
 .\n\nIt sits at the edge of what this catalog is for. It has dates\, rules
 \, an exchange and categories\, so it is a scheduled operating event with 
 a schedule worth publishing\; but it is scored through the SOTA database r
 ather than by a log submitted to the sponsor\, and 'Activator' and 'Chaser
 ' are roles rather than entry classes. Encoded on the same reasoning as UB
 A's Belgian Mills Award\, which is also an award-shaped event with real da
 tes. Sourced from the SARL Contest Manual\, which carries this contest's f
 ull rules and names its organising body -- the venue in which South Africa
 n clubs publish their rules\, not a listing of them. See data/sources.md\,
  'Nine South African clubs\, one manual'.\nRules: https://mysarl.org.za/wp

SUMMARY:ARRL 10 GHz and Up Contest\, Round 2
DESCRIPTION:Sponsor: ARRL\nModes: Mixed\nBands: 3cm\nBand note: 10 GHz thro
 ugh light\nDuration: 46h 59m\nExchange: not recorded yet — see the spons
 or's rules below\nLogs due: 2027-10-20\nNote: CORRECTION: this was stored 
 as a local-time contest running 0600 local Saturday to 2359 local Sunday. 
 ARRL has since moved it to fixed UTC and says so explicitly in the rules. 
 It is now a plain UTC record -- 0900Z Saturday to 0759Z Monday -- and carr
 ies no timezone or local_rolling flag. Operating time is capped at 42 hour
 s inside that 47-hour window. Also resolves the suspected typo flagged ear
 lier: ARRL's rule reads 'Third full weekend of August AND SEPTEMBER'\, so 
 a single rule covers both rounds and the September anchor was right all al
 ong.\nRules: http://www.arrl.org/10-ghz-up

 PED BEING ASKED WHAT ELSE IT RUNS. NRAU is recorded in this registry as bl
 ocked\, correctly: nrau.net says its contest information is under revision
  and publishes no rules for NRAU-Baltic or the Nordic Activity Contests. B
 ut NRAU also organises this\, its flagship\, and it publishes complete rul
 es at a domain of its own. SAC appeared nowhere in the registry at all unt
 il the 2026-08-21 gap audit.\n\nTHE PAGE IS HEADED 2023 AND THE RULE IS ST
 ATED AS STANDING. The recurrence sentences say 'each year'\, which is the 
 form this catalog trusts -- the same form ARRL's generic calendar uses -- 
 and they reproduce that page's own 2023 dates. Re-read when NRAU publishes
  a newer edition.\nRules: https://www.sactest.net/blog/rules/
