Your new RadioShack 500-Channel
Mobile Trunk-Tracking 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, E.F.
Johnson LTR, and hybrid analog
trunking systems, which are extensively used in many 800 MHz, 900
MHz and UHF communication 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 2way 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 scanner monitors the
data channel frequency sent with a 2way 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 33,000 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:
Ten Channel-Storage Banks
you store 50 channels in each bank
(500 total channels), letting you group
channels so you can more easily identify calls.
Flexible Operation
— you can track
Motorola, GE/Ericsson, and E.F.
Johnson LTR trunking systems (used
by most trunking communications systems), letting you hear more calls than
many standard trunking scanners.

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.
This device complies with Part 15 of
FCC Rules
the
the following two conditions: (1) this
device may not cause harmful interference, and (2) this device must accept
any interference received, including
interference that may cause undesired
operation.

SCANNING LEGALLY
Your scanner covers frequencies
used by many different groups including police and fire departments, ambulance services, government agencies,
private companies, amateur radio ser-
vices, military operations, pager services, and wireline (telephone and
telegraph) service providers. It is legal
to listen to almost every transmission
your scanner can receive. However,
there are some transmissions you
should never intentionally listen to.
These include:
• telephone conversations (cellular,
cordless, or other private means
of telephone signal transmission)
• pager transmissions
• any scrambled or encrypted transmissions
According to the Electronic Communications Privacy Act (ECPA), you are
subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a
transmission unless you have the consent of a party to the communication
(unless such activity is otherwise illegal).
This scanner is designed to prevent
reception of illegal transmissions, in
compliance with the law which requires that scanners be manufactured
in such a way as to not be easily modifiable to pick up those transmissions.
Do not open your scanner's case to
make any modifications that could allow it to pick up transmissions that it is
not legal to listen to. Doing so could
subject you to legal penalties.
You must install an antenna before
you can operate the scanner. Your local RadioShack store sells a variety of
scanner antennas for both mobile and
base-station use. Choose the one that
best meets your needs.
When deciding on a mobile or basestation antenna and its location, consider these points.
• The antenna should be as high as
possible on a vehicle or a house.
• The antenna and its cable should
be as far as possible from sources
of electrical noise (ignition systems, gauges, and so on).
• The antenna should be vertical for
the best performance.

CTCSS/DCS
Channel Storage Banks
To make it easier to identify and select
the channels you want to listen to,
channels are divided into 10 banks
(0–9) of 50 channels (00 to 49) each.
Use each channel-storage bank to
group frequencies, such as those
used by the police department, fire department, ambulance services, or aircraft (see “Guide to the Action Bands”
on Page 45). For example, the police
department might use four frequencies, one for each side of town. You
could program the police frequencies
starting with 000 (the 1st channel in
bank 0) and program the fire department frequencies starting with 100
(the 1st channel in bank 1). The first
digit identifies the bank (0–9). The
second and third digits identify the
channel within the bank (00–49).
Continuous Tone Coded Squelch System (CTCSS) and Digital Coded
Squelch (DCS) are two methods used
to prevent interference by other radio
communications. Your scanner can
receive transmissions that use these

PL codes are low-frequency audio
tones that are used to differentiate different users on the same channel. PL
codes appear according to the EIA
standard CTCSS tones, and range

are displayed directly as a frequency.
Search Banks
This scanner is able to search 10
search banks. You can also replac e a
bank with one of the preprogrammed
service bands. (For the default setting,
see “Searching a Preprogrammed

DPL Codes
DPL codes are similar to PL codes,
except they might be transmitted as
either tones or digital codes. Although
there are as many as 4096 DPL
codes, only about 100 are actually

LTR systems are trunking systems
used primarily by business or private
communications service providers,
such as taxicabs, delivery trucks, and
repair services. These systems encode all trunking information as digital
subaudible data that accompanies
each transmission. Users on an LTR
system are assigned to specific talk
groups, which are identified by the radio as six-digit numbers. These numbers are in the form

When the scanner receives a transmission on a channel set to the LTR
mode, it first decodes the LTR data included with the transmission. In the
open mode, the scanner stops on the
transmission and displays the talk
group ID on the bottom line of the display. In the closed mode, the scanner
only stops on the transmission if the
LTR data matches a talk group ID that
you have stored in the bank’s talk
group ID list and have not locked out.
LTR systems are frequently programmed so that each radio has a
unique ID code.
Motorola Mode
When the scanner receives a transmission on a channel set to the Motorola mode, it first decodes the talk
group ID data included with the transmission. In the open mode, the scanner stops on the transmission and
displays the talk group ID on the bottom line of the display. In the closed
mode, the scanner only stops on the
transmission if the talk group ID
matches a talk group ID that you have
stored in the bank’s talk group ID list
and have not locked out.

Motorola systems are trunking systems used primarily by business and
public safety groups to efficiently allocate a small number of frequencies
(as few as 5) to many groups of users
(as many as several thousand). To do
this, each group of users in the system
is assigned to a specific talk group.
For example, the east side patrol officers might all be assigned to talk group
2160. One channel in the system is
continuously transmitting data that
identifies which talk groups are active
on which channel. In addition, this talk
group information is also transmitted
as subaudible data on each active

to enter an invalid talk group ID, the
scanner rounds the ID down to the
next valid ID.
Type I/II hybrid systems use both
fleet-subfleet and 5-digit formats for
talk group IDs.
EDACS frequencies are organized in
a specific order. Each frequency is assigned a Logical Channel Number
(LCN). For the scanner to correctly
switch to an active frequency, you
must program the frequencies in LCN
order, starting with Memory 01.
EDACS talk group IDs are entered as

EDACS systems are trunking systems
used primarily by business or private
communications service providers, as
well as by some public safety organizations. EDACS systems transmit active talk group information only on a
dedicated control channel.
.
When there is activity on an EDACS
system, that information is sent out on
the control channel. The scanner decodes the ID for the active talk group.
In the open mode, the scanner then
goes to the transmission and displays
the talk group ID on the bottom line of
the display. In the closed mode, the
scanner only goes to transmissions
that have IDs that match a talk group
ID that you have stored in the bank’s
talk group ID list and have not locked
out.
Because EDACS scanning requires
clear reception of the control channel
at all times, EDACS systems tend to
have a smaller usable area. An external antenna can greatly improve
EDACS scanning in a fringe area. If

CHANGING THE OPEN/
CLOSED MODE
You can set each of the scanner’s
banks to open mode or closed mode.
When a bank is set to open mode, the
scanner receives all transmissions on
the frequencies in that bank. When a
bank is set to closed mode, the scan-
ner receives transmissions only when
a preset ID code is also transmitted,
and the ID code appears. In closed
mode, the scanner does not receive
transmissions if they do not have an
ID code or if the ID code does not
match the preset ID code.
Note:
You can set AM and FM frequencies within banks to open or
closed mode.
Follow these steps to select a bank
and change it to open or closed mode.
If you want to listen to private line or

store all the trunking group frequencies in one bank (see “Storing Known
Frequencies into Channels” on
Page 22) and input ID codes in the ID
memory (see “Finding and Storing Active Frequencies” on Page 25). To listen to the transmission, the mode of
the programmed channel mu st be the
same as that of the trunking channel
(LT, MO, or ED).
When an ID code is received, the ID
list for the bank is searched, and if
found, the text name stored for the ID
appears. If not found, scanning resumes immediately unless the bank is
in open trunking mode.
Note:
There might be more than one
talk group transmitting at a time in
some Motorola trunking systems. If
you set the scanner to manually tune
in Motorola trunking mode, you will
hear the talk group on that channel,
but the display will alternate between
all active IDs.

UNDERSTANDING
TRUNKING
In the past, groups that transmit frequently, such as police departments,
could transmit on only a few frequencies. This resulted in heavy traffic and
often required 2-way radio users to
wait for a specific frequency to clear
before transmitting. Trunked systems
allow more groups of 2-way radio users to use fewer frequencies. Instead
of selecting a specific frequency to
transmit on, a trunked system chooses one of several frequencies when
the 2-way radio user transmits. The
system automatically transmits the
call on that frequency, and also sends
a code that identifies that 2-way radio
user’s transmission on a control channel.
This scanner lets you easily hear both
the call and response transmissions
for that 2-way radio user and therefore
follow the conversation. For EDACS
and Motorola (above 806 MHz range),
the scanner monitors the control channel between each transmission to identify talk groups. For some Motorola
(under 512 MHz range) and LTR systems, the scanner uses the subaudible
data sent with each transmission to
identify talk groups.

SETTING SQUELCH FOR
THE TRUNKING MODE
Your scanner automatically mutes the
audio during trunk scanning when it
decodes control channel data. However, we recommend you turn
clockwise and leave it set to a point
just after the hissing sound stops. This
lets the scanner quickly acquire the
data channel.

frequencies for Motorola Type I

PROGRAMMING
TRUNKING
FREQUENCIES
You program trunking frequencies just
like non-trunked frequencies, except
that you must store the appropriate
mode (MO, ED, or LT) with each frequency.
Notes:
• You can store only one trunked
EDACs and Motorola channel in a
bank. You can, however, mix LTR
and conventional channels in a
bank.
• If you are scanning UHF trunking
frequencies under the 512 MHz
range using subaudible data and
are not using a base frequency
and offset, lock out all data channels. See “Programming Motorola
Trunking Systems (UHF-Lo)” on
Page 38 and “Locking Out Channels, Frequencies, and Trunking

Programming Motorola
Trunking Systems (UHF-Lo)
You can program the scanner to receive transmissions in the UHF-Lo
band (380–512 MHz) of the Motorola
Trunking System. You can receive
these transmissions by:
• Checking the trunking system’s
base frequency and offset frequency. You must program the
system’s base frequency and offset frequency to do this.
• Decoding the subaudible data
transmitted with the signals. When
you do this, the scanner might
detect wrong IDs but you can easily receive trunking frequencies
without programming the base
and offset frequencies.
• The scanner automatically decodes subaudible data it receives
in the VHF band.
• If you try to enter an offset frequency in the VHF and UHF-Hi
bands (137–174 and 806–960
MHz), the scanner will ignore the
entry.
Follow these steps to program Motorola trunking frequencies in the UHFLo band.
1. Select the bank, then press
to enter the program mode.

To find the birdies in your individual scanner, begin by disconnecting the antenna
and moving it away from the scanner. Make sure that no other nearby radio or TV
sets are turned on near the scanner. Use the search function and search every frequency range from its lowest frequency to the highest. Occasionally, the searching
will stop as if it had found a signal, often without any sound. That is a birdie. Make a
list of all the birdies in your scanner for future reference.

Police Call Radio Guide including Fire and Emergency Services
The tuning location of a station can be expressed in frequency (kHz or MHz) or in
wavelength (meters). The following information can help you make the necessary
conversions.
1 MHz (million) = 1,000 kHz (thousand)
• To convert MHz to kHz, multiply the number of megahertz by 1,000:
30.62 (MHz) × 1000 = 30,620 kHz
• To convert from kHz to MHz, divide the number of kilohertz by 1,000:
127,800 (kHz) ÷ 1000 = 127.8 MHz
• To convert MHz to meters, divide 300 by the number of megahertz:
300 ÷ 50 MHz = 6 meters

CARE AND MAINTENANCE
Your RadioShack 500-Channel Mobile Trunk-Tracking Scanner is an example of
superior design and craftsmanship. The following suggestions will help you care for
your scanner so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the scanner only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices and
distort or melt plastic parts.
Keep the scanner away from dust and dir t, wh ich ca n ca us e p re m atu r e
wear of parts.
Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly.
Wipe the scanner with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the scanner.
Modifying or tampering with the scanner’s internal components can cause a malfunction and might invalidate its warranty and void your FCC au tho rization to operate it. If your scanner is not performing as it should, take it to your local
RadioShack store for assistance.
