GE/Ericsson EDACS . Those systems are extensively used in many 800 MHz, 900 MHz, and UHF communica- tion 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 se- lecting a specific frequency for a transmission, the user simply selects a talk group. The trunking system auto- matically transmits the call on the first available frequen- cy, and also sends (on a different frequency called a data channel) a code that uniquely identifies that trans- mission.

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 scanner lets you select and monitor the data channel fre- quency 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 it 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 tedious and complicated programming.

This scanner gives you direct access to over 37,000 ex- citing frequencies, including police and fire departments, 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) images, so you hear only the selected frequency.
