What is a Talkgroup?
A talkgroup is analogous to a radio channel in a trunked radio system. The trunk controller for the system will, when a radio’s PTT is pressed, assign a free frequency for the radio to transmit on and order all radios on that talkgroup to switch to that frequency. Frequencies assigned will change every time someone talks into their radio. A TrunkTracking scanner will listen to the system’s control channel and follow frequency changes for whatever talkgroup you are listening to.
