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 Companding On or Off by using a
pre-programmed Companding button or, via the
menu.
