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.
You can switch On or Off Companding by
using a pre-programmed Companding button
or via the menu.
