- Amateur-radio operators using FT4
- Worth noticing
- The rules require one transceiver and keep the station and antennas within a 300-metre-diameter circle.
Field notes
The rules define specific operating frequencies for each of six HF bands and set a 24-hour contest window, with logs accepted for a short period afterward. They also lay out station limits, categories, exchanges, scoring, certificates, and disqualification provisions. A downloadable 10-QSO Cabrillo example gives entrants a concrete reference format.
