SUMMARY:OK/OM DX Contest\, SSB
DESCRIPTION:Sponsor: CRK / SARA\nModes: SSB\nBands: 160m\, 80m\, 40m\, 20m\
 , 15m\, 10m\nBand note: 1.8 through 28 MHz\, WARC bands excluded\nDuration
 : 23h 59m\nExchange: Non-Czech and Slovak stations send a signal report + 
 a QSO number starting with 001\; Czech and Slovak stations send a signal r
 eport + their three-letter county code.\nLogs due: 2027-04-18\nNote: The p
 arenthetical deadline (19 April 2026\, 2359 UTC) is the right date for the
  seven-day interval but 23:59 rather than the 11:59 that end-plus-7-days g
 ives\; the interval is the stated rule\, so the interval is encoded. WORDI
 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
 he link checker will keep reporting it as such until the Czech Radio Club 
 fixes the host.\nRules: http://www.okomdx.crk.cz/index.php?page=SSB-rules-
