60 metres

Related wiki pages Bands, Propagation Antenna

The 60 metre band is an unusual HF band in that operation is limited to five specified channels, and the maximum power output allowed is defined by ERP rather than input power. It was created primarily to allow emergency communication during times when propagation conditions dictated use of a band higher frequency than 80 metres but lower than 40 metres.

The 60m Band is not available to hams in all countries, for example Australia.

Equipment
Because 60 metres was allocated relatively recently, most older amateur HF equipment does not support it. However, nearly all new multiband HF equipment can operate on 60 metres.

Modulation
Only Upper Sideband Modulation (USB) is permitted on the 60 metre band. Unlike all other HF bands, CW operation is not allowed anywhere in the band. Amateurs are secondary users, and must yield the band to the primary users on request. Limiting amateur modulation to USB guarantees that the primary users can communicate with amateurs when necessary.
