FEATURES
Your RadioShack PRO-92 500-Channel Portable Trunk-
ing Scanner is one of a new generation of scanners de-
signed to track Motorola
®
Smartnet and Privacy Plus
systems, plus GE/Ericsson (EDACS
®
(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 se-
lecting a specific frequency for a transmission, the user
simply selects a talk group. The trunking system automat-
ically transmits the call on the first available frequency,
and also sends 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
PRO-92 monitors the data sent with a 2-way radio trans-
mission, 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 search 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 33,000 fre-
quencies including those used by police and fire depart-
ments, ambulance services, government agencies, air,
and amateur radio services.
