RadioShack PRO-2052
Introduction
Your new RadioShack PRO-2052 1000-Channel Dual Trunking Trunk-Tracker Home Scanner is one of a new generation of scanners designed to track Motorola Type 1, Type 11 (such as Smartnet and Privacy Plug, GE/Ericsson EDACS), and hybrid analog trunking systems, which are extensively used in many 800 MHz, 900 MHz and UHF communications 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 group of frequencies. Instead of selecting a specific frequency for a transmission, the 2-way radio user simply selects a talk group. The trunking system automatically transmits the call on the first available frequency, and also sends a code that uniquely identifies that 2-way radio user's transmission on a different frequency called a data channel.
Since the trunking system might send individual 2-way radio user's calls and response transmissions on different frequencies, it is difficult to listen to trunked communications using a regular scanner. The PRO-2052 monitors the data channel frequency sent with a 2-way radio user's transmission and instantly switches to an active frequency, so you can hear the call and response for that 2-way radio user and 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 without tedious and complicated programming.
This scanner gives you direct access to over 51,000 exciting frequencies, including those used by police and fire departments, ambulance services, and amateur radio services, and you can change your selection at any time.
Features
Your scanner also has these special features:
Flexible Operation - you can track both Motorola and GE/Ericsson
trunking systems (used by most trunking
communications systems today), letting you
hear more calls than many standard trunking
scanners.
Frequency Coverage to - provides a wide range of frequencies you
1.3 GHz can listen to.
Twenty Channel-Storage Banks - lets you store 50 channels in each bank
(1000 total channels, letting you group
channels so you can more easily identify
calls.
NWR-SAME/Weather Alert - you can set the scanner to sound an alert
when it receives NOAA's Specific Area
Message Encoding (SAME) coded weather
emergency signal, providing more complete
information about weather conditions in
your immediate area and letting you avoid
hearing alerts for geographical areas that
do not interest you.
Remote PC Function - lets you control the PRO-2052 from your
personal computer.
Five Scan Lists - lets you store up to 50 IDs in each
tracking bank (up to a total of 1000).
Triple-Conversion Circuitry - virtually eliminates any interference from
IF (intermediate frequency) images, so you
hear only the selected frequency.
Scan Delay - delays scanning for about 2 seconds before
moving to another channel in conventional
mode, so you can hear more replies that are
made on the same channel. In trunk scanning
mode, it delays for about 5 seconds before
moving to another ID.
Lock-Out Function - lets you set your scanner to skip over
specified channels or frequencies when
scanning or searching, and skip over IDs
when tracking trunked systems.
Priority Channels - lets you program one channel in each bank
(10 in all). As the scanner scans a bank,
it checks the bank's priority channel every
2 seconds so you don't miss transmissions
on that channel.
Five Service-Search Banks - lets you search preset frequencies in
separate public service, police, fire/
emergency, aircraft, and weather banks to
make it easy to locate specific types of
calls.
HyperSearch and HyperScan - lets you set the scanner to search at up to
300 steps per second (in frequency bands
with 5 kHz steps) and scan at up to 50
channels per second, to help you quickly
find interesting broadcasts, (The normal
search speed is 100 steps per second).
Data Signal Skip - lets you set the scanner to skip non
modulated or data signals during scanning
and searches. This lets the scanner avoid
non-voice signals, making a scan or search
faster.
Manual Access - you can directly access any stored channel
by entering that channel's number.
Liquid-Crystal Display - makes it easy to view and change
programming information.
Display Backlight - makes the scanner easy to read in low-light
situations.
Supplied Telescoping Antenna - provides good reception of strong local
signals.
External Antenna Terminal - lets you connect an external antenna with a
BNC connector to the scanner for improved
reception of distant/weaker signals.
Memory Backup - keeps the channel frequencies stored in
memory in the event AC power goes out.
Key Confirmation Tones - the scanner sounds a tone when you perform
an operation correctly, and an error tone
if you make an error.
Duplicate Channel alert - warns you when the frequency you are
storing already exists in memory.
Disconnect Tone Detect - the scanner automatically tunes to the
trunking data channel when it receives a
disconnect transmission. You can turn this
feature off to continuously monitor a
channel with a weak transmission during
disconnected conversations.

FCC Notice
Your scanner might cause radio or TV interference even when it is operating properly. To determine whether your scanner is causing the interference, turn off your scanner. If the interference goes away, your scanner is causing it. Try the following methods to eliminate the interference:
Move your scanner away from the receiver.
Connect your scanner to an outlet that is on a different electrical circuit from the receiver.
Contact your local RadioShack store for help.
