In this newsletter, frequencies used by each trunked system appear first, followed by a list of talkgroups. In the talkgroup list, the first column, when known, is the talkgroup channel designation (what would normally be considered the channel number), followed by the Motorola and TrunkTracker talkgroup IDs.
Even when the TrunkTracker receives a strong signal, talkgroup IDs displayed by the TrunkTracker for a specific talkgroup may not always be consistent. The problem is that the TrunkTracker includes the call-type digit when determining the talkgroup ID. Motorola radios, however, do not rely on the call-type digit to determine the talkgroup ID. Normally the call-type is zero (0). When certain features are activated on a talkgroup, such as an emergency button, crosspatch, simulcast or encryption, the talkgroup may appear up to 15 digits higher.
In Anne Arundel County for example, 1-B would normally register on the TrunkTracker as 57392. But because 1-B and 1-D are frequently crosspatched, the TrunkTracker ID for 1-B registers as 57395. On Motorola radios, however, it remains the same talkgroup.
