UHF CB - Selective Calling (Selcall)

Selective Calling (Selcall)

Selective calling (Selcall) allows an individual radio to call another radio using a sequence of tones, usually presented to the user as a series of 5 numbers. UHF CB radios can be set to be completely silent until they receive a series of tones matching a pre-programed sequence. Radios which have this feature usually indicate that a call has been received by emitting a number of beeps and by opening the squelch.
