SUMMARY:RSGB AFS Contest\, Datamodes
DESCRIPTION:Sponsor: RSGB Contest Committee\nModes: RTTY\, Digital (PSK63)\
 nBands: 80m\, 40m\nBand note: 80 m and 40 m. CW 3510-3570 and 7000-7040 kH
 z\; SSB 3600-3775 and 7060-7200 kHz\; PSK63 3580-3590 and 7040-7045 kHz\; 
 RTTY 3590-3620 and 7045-7060 kHz.\nDuration: 4h\nExchange: RS(T) plus a se
 rial number starting at 1 and incrementing by 1\, irrespective of band.\nE
 ligibility: Entry limited to G. K stations may be worked but cannot submit
  an entry.\nNote: ALL THREE HANG OFF ONE ANCHOR\, WHICH IS WHAT FIVE YEARS
  OF RSGB'S DATES SHOW. The AFS CW Saturday is the anchor\; Datamodes is th
 e Sunday eight days later and SSB the Saturday fourteen days later. No con
 sistent ordinal describes Datamodes on its own -- it is the third Sunday i
 n 2022 and 2023 and the second in 2024\, 2025 and 2026 -- so encoding it a
 s an ordinal would have been wrong in two of the five years RSGB published
 .\n\nTHE 1 JANUARY EXCEPTION IS EVIDENCED\, NOT ASSUMED. 1 January 2022 wa
 s itself a Saturday and RSGB ran AFS CW on the 8th\, so `exclude_dates: [[
 1\, 1]]` is what reproduces that year -- the same shape ARRL RTTY Roundup 
 states outright for its own New Year clash. RSGB does not state it in word
 s\, but unlike TRAC's equivalent this is not a single year's evidence fitt
 ed to a rule: it is the only reading that fits all five years across all t
 hree contests. It next decides anything in 2028.\nRules: https://www.rsgbc
