Uniden UBCT9 Owner's Manual page 9

Sharing of the available public service frequencies, or trunking, allows cities,
counties, or other agencies to accommodate hundreds of users with relatively
few frequencies. Following a conversation on a trunked system using a scanner
is difficult, if not impossible. Because when there's a short break during the
conversation you're monitoring, it's possible that the talk group will be assigned
to a completely different frequency in the trunked system. This type of scanning is
difficult and frustrating.
TrunkTracker Technology changes this! Not only does your new UBCT9 scan
channels like a conventional scanner, it actually follows the users of a trunked
radio system. Once you know a talk groups 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.
