The first full weekend of January, from Saturday at 18:00 UTC, for 30 hours. It never starts on January 1: then it moves to the following weekend.
Single operators may operate 24 of the 30 hours; multi-operator entries the whole period.
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 is RTTY only: the digital segments get crowded and FT8 and FT4 activity near the usual dials feels it.
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 ARRL. They change from year to year: read them before you send a log.
