SUMMARY:OK DX RTTY Contest
DESCRIPTION:Sponsor: CRK\nModes: RTTY (Baudot)\nBands: 80m\, 40m\, 20m\, 15
 m\, 10m\nDuration: 24h\nExchange: RST + CQ Zone.\nNote: TWO PROBLEMS IN TH
 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
