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.
