Your RadioShack Handheld Scanner is one of a new
generation of scanners designed to track Motorola
®
Type
I and Type II (such as Smartnet
®
and Privacy Plus
®
) and
hybrid analog trunking systems, plus GE/Ericsson
(EDACS
®
) and EF Johnson (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 auto-
matically transmits the call on the first available frequen-
cy, and also sends 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
scanner 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.
Your scanner includes these features:
Simultaneous Trunking Operation
— tracks three
trunking systems (LTR, Motorola, and EDACS) and con-
ventional systems at the same time.
10 Channel-Storage Banks
— let you store 50 chan-
nels in each bank (500 channels) to group channels so
calls are easier to identify.
