If a radio channel is defined as a P25 Conventional Digital Channel, it will only receive
P25 digital signals.
If a radio channel is defined as an Analogue FM channel, it will receive both P25
Digital* and Analogue FM signals.
A radio channel defined as a P25 Trunked network will automatically start searching
for the pre-programmed network, and only receive signals from that network once it
has service.
Note:-When an Analogue FM channel is selected and in Monitor mode, all
unencrypted digital P25 traffic will be heard regardless of NAC or Talk Group.
