COMPANDING

Companding is a collective term to define compressing the audio signal on transmission and expanding the audio signal on reception. The overall effect is to reduce noise in the received signal, giving you crisper, clearer audio clarity. Companding should only be used when other radios in your system have the same companding feature available.
