Your RadioShack Base Scanner is one of a
new generation of scanners designed to
track Motorola

Type I and II (such as
Smartnet

and Privacy Plus

) and hybrid
analog trunking systems, and GE/Ericsson
(EDACS

) type systems, used extensively in
many communication systems.
Trunking communications systems let a
large group of 2-way radio users (or even dif-
ferent 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 trunk-
ing system automatically transmits the call
on the first available frequency, and also
sends 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 communica-
tions using a regular scanner. The trunking
scanner monitors the data 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 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.
This scanner gives you direct access to over
59,000 frequencies including those used by
police and fire departments, ambulance ser-
vices, government agencies, air, and ama-
teur radio services.
Your scanner includes these features:
Simultaneous Trunking Operation —
tracks two trunking systems (Motorola and
EDACS) and conventional systems at the
same time.
Automatic Channel Programming — auto-
matically determines the group trunking fre-
quencies, for Motorola trunking systems
only, once the control channels are pro-
grammed.
10 Channel-Storage Banks — let you store
30 channels in each bank (300 channels) to
group channels so calls are easier to identify.
10 ID-Storage Banks — let you store 1,000
IDs in 10 ID banks that have 5 sub-ID banks.
20 IDs are programmed in each sub-ID bank
and let you easily identify the ID code.
Weather Alert — automatically sounds the
alarm tone to advise of hazardous weather
conditions when it detects the alert signal on
the local National Oceanic and Atmospheric
Administration (NOAA) weather channel dur-
ing priority operation.
Digital Weather Alert — displays the weath-
er event text with four alert levels so you can
see and hear the reason for the alert.
Data Cloning — lets you transfer the pro-
grammed data to another PRO-2053 or
PRO-93 scanner. You can also upload or
download the programmed data to or from a
PC using an optional PC interface kit.
12-Character, 4-Line, Alphanumeric Dis-
play — shows you detailed operating infor-
mation clearly.
Triple Conversion Superheterodyne Re-
ceiver — virtually eliminates any interfer-
ence from intermediate frequency (IF)
images, so you hear only the frequency you
select.
