SUMMARY:Helvetia Contest
DESCRIPTION:Sponsor: USKA\nModes: CW\, SSB\, RTTY\, Digital\, FT8/FT4 (PSK3
 1\, PSK63)\nBands: 160m\, 80m\, 40m\, 20m\, 15m\, 10m\nDuration: 23h 59m\n
 Exchange: Swiss stations send RS(T) and their canton abbreviation (59 ZH\,
  599 ZH)\; stations outside Switzerland send RS(T) and a serial number of 
 at least three digits.\nLogs due: 2027-05-03\nNote: The last full weekend 
 of April\, encoded as n=-1: April 2026 has full weekends on the 4th/5th\, 
 11th/12th\, 18th/19th and 25th/26th\, so the rule gives 25-26 April\, whic
 h is what USKA's own KW-Contest page prints. USKA also prints 24-25 April 
 2027 there\, and the rule reproduces that too. Operators must take a six-h
 our rest in at most two periods\; the record carries the full 24-hour wind
 ow because that is when the contest is on air.\nRules: https://uska.ch/dow
