FEATURES

Your RadioShack Handheld Scanner is one of a new generation of scanners designed to track

Motorola® Type I and II (such as Smartnet® and Privacy Plus®) and hybrid analog trunking systems,

GE-Ericsson (EDACS®) type systems, and EF Johnson (LTR) type systems which are extensively used

in many communication systems.

Trunking communications systems let a large group of 2-way radio users (or even different groups of

2-way radio users) efficiently use a set of frequencies. Instead of selecting a specific frequency for a

transmission, the user simply selects a talk group. The trunking system automatically transmits the call

on the first available frequency, and also sends a code that uniquely identifies that transmission.

Since the trunking system might send a call and its response on different frequencies, it is difficult to

listen to trunked communications using a regular scanner. The trunking scanner monitors the data sent
