Whats a trunking or talk group ID?
On conventional radio systems, we tend to associate physical frequencies with the agencies that use them. On trunked radio systems, a different representation must be used since any frequency can be used by any agency on that system. Since a trunked radio system is at the mercy of the computer controller, it is beneficial to use the same representation that it does to identify the various agencies found on a system. This is done when the system is first installed and programmed with various numbers which are used to identify different agencies and their different purposes. Such numbers are generally refered to as trunking IDs or talk group IDs. One of the TrunkTracker’s tasks is to display the ID of the user when it detects a transmission on the system. If you have no refernece for the system you use, you’ll have to figure out which agencies use each ID and for what purpose. Once this is done, you can select the IDs you wish to monitor exclusively and program them into a Scan List.
