Uniden BC785D manual What is Apco Project 25 Digital Communications?

TrunkTracker III changes this! Not only does your new BC785D scan channels like a conventional scanner, it actually follows the users of a trunked radio system. Once you know a talkgroups ID, you won’t miss any of the action.

If you're a new scanner enthusiast, you may want to read the first part of this manual and use your scanner in conventional mode before you begin trunk tracking. Understanding scanning fundamentals and its terminology will make trunk tracking much easier. A glossary of other commonly used terms is provided in the back. (Refer to the "Glossary of Terms" section.) But if you're already an experienced scanner operator, you may want to skip to Programming and Receiving Digital and Trunked Systems on page 46.
