Radio channels may be configured with the Field Programmer as specific frequencies or as
auto scan types. When an auto scan channel is selected, it will immediately go into scan
mode. Selecting another non-autoscan channel will stop the scan.
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.
* While in Analogue mode, all unencrypted digital P25 traffic will be heard regardless of NAC
or Talkgroup.
