The last full weekend of July, from Saturday at 12:00 UTC, for 24 hours.
Rule inferred from the 2026 and 2027 dates: 2027 falls on July 24-25, not on the last Saturday (July 31), so it is the last full weekend.
It runs on 80 m, 40 m, 20 m, 15 m, and 10 m.
160 m is not part of it and stays free.
It runs in CW and SSB, so both the CW and the phone segments are busy.
The WARC bands (30, 17 and 12 m) stay contest-free by IARU agreement: that is where DXpeditions and quiet QSOs go.
You do not need to be a contester to hand out a few points: answer a CQ, give the exchange exactly as the rules ask, and log the contact. Most organisers take logs in Cabrillo format through an upload page, with a deadline a few days after the end, and even a short log helps the checking. Check-logs are welcome too.
It is one of the 31 contests in the HamQSO calendar, and the feed adds its next editions to your calendar.
The rules are published by RSGB. They change from year to year: read them before you send a log.
