Features

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.
