SUMMARY:DDFM 50 MHz
DESCRIPTION:Sponsor: REF\nModes: SSB\, CW\, FM\nBands: 6m\nDuration: 24h\nE
 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
