Your new RadioShack PRO-2050
VHF/UHF/Air/800MHz 300-Channel
TrunkTracker Home Scanner is one of
a new generation of scanners de-
signed to track Motorola Type I,
Type II (such as Smartnet and Priva-
cy Plus), and hybrid analog trunking
systems, which are extensively used
in many 800 MHz communication sys-
tems.
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-2050 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 30,000 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.
Your scanner also has these special
features:
Ten Channel-Stora
g
e Banks
— let
you store 30 channels in each bank to
group channels so you can more easi-
ly identify calls.
Five Scan Lists
— let you store up to
50 IDs in each tracking bank (up to a
total of 500).
Triple-Conversion Circuitr
y
— virtu-
ally eliminates any interference from
IF (intermediate frequency) images,
so you hear only the selected frequen-
cy.
