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 I, Type II
(such as Smartnet
and Privacy
Plus
), GE/Ericsson EDACS, and hy-
brid analog trunking systems, which
are extensively used in many 800
MHz, 900 MHz and UHF communica-
tion 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 fre-
quencies. Instead of selecting a spe-
cific frequency for a transmission, the
2-way radio user simply selects a talk
group. The trunking system automati-
cally 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 dif-
ferent frequency called a data chan-
nel.
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 regu-
lar scanner. The PRO-2052 monitors
the data channel frequency sent with
a 2-way radio user’s transmission and
instantly switches to an active fre-
quency, 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 con-
ventional transmissions, and is pre-
programmed 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 compli-
cated 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 trunk-
ing systems (used by most trunking
communications systems today), let-
ting you hear more calls than many
standard trunking scanners.
Frequency Coverage to 1.3 GHz
provides a wide range of frequencies
you can listen to.
Twenty Channel-Storage Banks
let you store 50 channels in each bank
(1000 total channels), letting you
group channels so you can more easi-
ly identify calls.
