FEATURES

Your RadioShack PRO-91 150-Channel Handheld Trunking Scanner is one of a new generation of scan- ners designed to track Motorola Type I and Type II (such as Smartnet and Privacy Plus) and hybrid ana- log trunking systems, which are extensively used in many 800 MHz communication systems.

Trunking communications systems let a large group of 2-way radio users (or even different groups of 2-way ra- dio users) efficiently use a large range of frequencies. Instead of selecting a specific frequency for a transmis- sion, the user simply selects a talk group. The trunking system automatically transmits the call on the first avail- able frequency, and also sends (on a different frequen- cy called a data channel) a code that uniquely identifies that transmission.

Since the trunking system might send a call and its re- sponse on different frequencies, it is difficult to listen to trunked communications using a regular scanner. The PRO-91 lets you select and monitor the data channel frequency sent with a 2-way radio transmission, so you can hear the call and response for that user and more easily “follow” the conversation.

The scanner also lets you scan conventional transmis- sions, and is preprogrammed with service banks for convenience. By pressing a single button, you can quickly search those frequencies most commonly used by public service and other agencies without te- dious and complicated programming.

This scanner gives you direct access to over 30,000 ex- citing frequencies, including police and fire depart- ments, ambulance services, and amateur radio services, and you can change your selection at any time.

Your scanner also has these special features:

Triple-Conversion Circuitry — virtually eliminates any interference from IF (intermediate frequency) im- ages, so you hear only the selected frequency.
