RadioShack PRO-94 1000-Channel Handheld Trunking Scanner
Owner’s and Service Manuals
Your RadioShack PRO-94 1000-Channel Handheld Trunking Scanner is one of a new generation of scanners designed to track Motorola Type I, Type II, hybrid analog systems, (such as Smartnet and Privacy Plus) plus GE/Ericsson EDACS. Those systems are extensively used in many 800 MHz, 900 MHz, and UHF 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 (on a different frequency called a data channel) 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 PRO-94 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 transmissions, 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 exciting frequencies, including police and fire departments, ambulance services, and amateur radio services, and you can change your selection at any time.
