16 Οκτ 2020 · Band plans exist to guide radio amateurs on the optimum use of spectrum. For effective communications by radio, consideration is needed of many different types of transmission modes available today.
The last channel, 5405kHz is common to the UK amateur 5-MHz experimental band plan. This new allocation presents some new twists in amateur HF operation as well as some unfamiliar technical demands.
Amateur radio operators may transmit messages via unmanned transmitting stations during coordinated emergency, and disaster preparedness exercises, limited to the duration of such exercises, using a bandwidth not exceeding 2 700 Hz.
This is particularly important in the 30 meter band where the amateur service only has secondary status. Amateur radio operators may transmit messages via unmanned transmitting stations during coordinated emergency, and disaster preparedness exercises, limited to the duration of such exercises, using a bandwidth not exceeding 2700 Hz.
