UHF channels and frequencies
Once contact is established on the calling channel, both stations should
move to another unused "SIMPLEX" channel to allow others to use the
calling channel.
Channels 22 and 23 are for Telemetry and Telecommand use, voice
communications are not allowed on these channels by law.
Channel 9 and above are the best choices for general use in Simplex mode.
