FEATURES

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

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

— virtu-

ally eliminates any interference from

IF (intermediate frequency) images,

so you hear only the selected frequen-

cy.

20-430.fm Page 2 Wednesday, August 4, 1999 1:29 PM

Scan Delay — delays scanning for

about 2 seconds before moving to an-

other channel in conventional mode,

so you can hear more replies that are

made on the same channel. In trunk

tracking 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 scan-

ning or searching, and skip over IDs

when tracking trunked systems.

Priority Channels — lets you pro-

gram one channel in each bank (10 in

all). As the scanner scans a bank, it

checks the bank’s priority channel ev-

ery 2 seconds so you don't miss trans-

missions on that channel.

Five Service-Search Banks — lets

you search preset frequencies in sep-

arate public service, police, fire/emer-

gency, aircraft, and weather banks, to

make it easy to locate specific types of

calls.

HyperSearch and HyperScan —

let 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 broad-

casts. (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 fast-

er.

Manual Access — lets you directly

access any stored channel.

Liquid-Crystal Display — makes it

easy to view and change program-

ming information.

Display Backlight — makes the

scanner easy to read in low-light situa-

tions.

Supplied Telescoping Antenna —

provides good reception of strong lo-

cal 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 chan-

nel frequencies stored in memory for

an extended time.

Key Confirmation Tones — the

scanner sounds a tone when you per-

form an operation correctly, and an er-

ror tone if you make an error.

Duplicate Channel Alert — warns

you when the frequency you are stor-

ing already exists in memory.

20-430.fm Page 3 Wednesday, August 4, 1999 1:29 PM

Your PRO-2050 scanner can receive

all of these bands:

Note: See “Specifications” on Page 51

for more information about the scan-

ner’s frequency steps.

FCC NOTICE

SCANNING LEGALLY

Scanning is a fun and interesting hob-

by. You can hear police and fire de-

partments, ambulance services,

government agencies, private compa-

nies, amateur radio services, aircraft,

and military operations. It is legal to

listen to almost every transmission

your scanner can receive. However,

there are some electronic and wire

communications that are illegal to in-

tentionally intercept. These include:

• Telephone conversations (cellu-

lar, cordless, or other private

means of telephone signal trans-

mission)

• Pager transmissions

• Scrambled or encrypted transmis-

sions

According to the Federal Electronic

Communications Privacy Act (ECPA),

as amended, you could be fined and

possibly imprisoned for intentionally

intercepting, using, or disclosing the

contents of such a transmission un-

less you have the consent of a party to

the communication (unless such activ-

ity is otherwise illegal). These laws

change from time to time and there

might be state or local laws that also

affect legal scanner usage.

PREPARATION

This scanner is designed primarily for

use in the home as a base station.

You can place it on a desk, shelf, or

table.

Your scanner’s front feet fold up or

down. Adjust them to give you the

best view of the display.

Your scanner’s display is protected

during shipment by a piece of blue

film. Peel off this film before you use

the scanner.

CONNECTING AN

ANTENNA

Connecting the Supplied

Antenna

You must install an antenna before

you can operate the scanner.

The supplied telescoping antenna

helps your scanner receive strong lo-

cal signals. To install the antenna,

screw it clockwise into the hole on the

scanner’s top.

The scanner’s sensitivity depends on

the antenna’s length and various envi-

ronmental conditions. For the best re-

ception of the transmissions you want

to hear, adjust the antenna’s length.

Connecting an Outdoor

Antenna

Instead of the supplied antenna, you

can connect an outdoor base-station

or mobile antenna (not supplied) to

your scanner using a BNC connector.

Your local RadioShack store sells a

variety of antennas. Choose the one

that best meets your needs.

When deciding on a mobile or base-

station antenna and its location, con-

sider these points:

Frequency Antenna Length

29–54 MHz Extend fully

108–174 MHz Collapse one

ment

406–956 MHz Collapse both

ments

20-430.fm Page 8 Wednesday, August 4, 1999 1:29 PM

• The antenna should be as high as

possible on the vehicle or building.

• The antenna and its cable should

be as far as possible from sources

of electrical noise (appliances,

other radios, etc.).

• The antenna should be vertical for

the best performance.

To connect an optional base-station or

mobile antenna, first remove the sup-

plied antenna from the scanner. Al-

ways use 50-ohm coaxial cable, such

as RG-58 or RG-8, to connect the

base-station or mobile antenna. For

lengths over 50 feet, use RG-8 low-

loss dielectric coaxial cable. If the an-

tenna cable’s connector does not fit in

the ANT. jack, you might also need a

Motorola-to-BNC antenna plug adapt-

er, such as RadioShack Cat. No. 278-

117. Your local RadioShack store car-

ries a wide variety of coaxial antenna

cable and connectors.

Once you choose an antenna, follow

the mounting instructions supplied

with the antenna. Then route the an-

tenna’s cable to the scanner and con-

nect the cable to the ANT. jack on the

back of the scanner.

DC 12V

ANT

Cautions:

• Do not run the cable over sharp

edges or moving parts that might

damage it.

• Do not run the cable next to power

cables or other antenna cables.

Warnin

: Use extreme caution

when you install or remove an out-

door antenna. If the antenna starts

to fall, let it go! It could contact

overhead power lines. If the anten-

na touches a power line, contact

with the antenna, mast, cable, or

guy wires can cause electrocution

and death. Call the power compa-

ny to remove the antenna. DO

NOT attempt to do so yourself.

CONNECTING POWER

Using AC Power

The scanner’s supplied AC adapter

lets you power the scanner from a

standard AC outlet. To connect power

to the scanner, insert the AC adapter’s

barrel plug into the DC 12V jack on the

back of the scanner, then plug the AC

adapter into a standard AC outlet.

ANT

20-430.fm Page 9 Wednesday, August 4, 1999 1:29 PM

Cautions:

• The supplied AC adapter supplies

12 volts DC power and delivers

500 milliamps. Its center tip is set

to positive, and its plug properly

fits the scanner’s DC 12V jack.

Using an adapter that does not

meet these specifications could

damage the scanner or the

adapter.

• Be sure to connect the AC

adapter to the scanner before you

connect it to an AC outlet, and dis-

connect the AC adapter from the

AC outlet before you disconnect it

from the scanner.

Warning: Do not use the AC adapt-

er’s polarized plug with an extension

cord receptacle unless the blades can

be fully inserted to prevent blade ex-

posure.

Using Your Vehicle’s Battery

Power

If your AC power fails (during an

emergency, for example), you can

power your scanner from your vehi-

cle’s cigarette lighter socket with an

optional DC cigarette lighter power ca-

ble, such as Cat. No. 270-1533 (not

supplied).

To connect an optional DC cigarette

lighter power cable, insert its barrel

plug into the DC 12V jack on the back

of the scanner, then plug the power

cable into your vehicle’s cigarette

lighter socket.

Cautions:

• If you use a DC cigarette lighter

power cable with the scanner, it

must supply 12 volts and at least

500 milliamps of DC automotive

power. Its center tip must be set to

positive, and its plug must cor-

rectly fit the DC 12V jack on the

back of the scanner. The recom-

mended power cable meets these

specifications. Using a power

cable that does not meet these

specifications could damage the

scanner or the power cable.

• If you use a cigarette lighter power

cable and your vehicle’s engine is

running, you might hear electrical

noise from the engine while scan-

ning. This is normal.

Note: Mobile use of this scanner is

unlawful or requires a permit in some

areas. Check the laws in your area.

CONNECTING AN

EXTENSION SPEAKER

In a noisy area, an amplified extension

speaker (such as Cat. No. 21-541),

positioned in the right place, might

provide more comfortable listening.

Plug the speaker cable’s 1/8-inch plug

into your scanner’s jack.

DC 12V

ANT

20-430.fm Page 10 Wednesday, August 4, 1999 1:29 PM

Note: Connecting an external speaker

disconnects the scanner’s internal

speaker.

CONNECTING AN

EARPHONE/

HEADPHONES

For private listening, you can connect

an earphone or headphones with a 1/8-

inch plug (such as Cat. No. 33-175 or

20-210) to the jack on the front of

the scanner. This automatically dis-

connects the internal speaker.

Listening Safely

To protect your hearing, follow these

guidelines when you use an earphone

or headphones.

• Do not listen at extremely high

volume levels. Extended high-

volume listening can lead to per-

manent hearing loss.

•Set

VOLUME to the lowest setting

before you begin listening. After

you begin listening, adjust VOL-

UME to a comfortable level.

• Once you set VOLUME, do not

increase it. Over time, your ears

adapt to the volume level, so a

volume level that does not cause

discomfort might still damage your

hearing.

20-430.fm Page 11 Wednesday, August 4, 1999 1:29 PM

UNDERSTANDING YOUR SCANNER

Once you understand a few simple terms we use in this manual and familiarize

yourself with your scanner’s features, you can put the scanner to work for you. You

simply determine the type of communications you want to receive, then set the

scanner to scan them.

A frequenc

is the tuning location of a station (expressed in kHz or MHz). To find

active frequencies, you can use the search function.

You can also search the service-search banks, which are preset groups of fre-

quencies categorized by type of service.

When you find a frequency, you can store it into a programmable memory location

called a channel, which is grouped with your other channels in a channel-stora

bank. You can then scan the channel-storage banks to see if there is activity on

the frequencies stored there. Each time the scanner finds an active frequency, it

stays on that channel until the transmission ends.

A LOOK AT THE FRONT PANEL

Your scanner’s keys might seem confusing at first, but this information should help

you understand each key’s function.

Note: Some of the scanner’s keys perform more than one function and are marked

with more than one label. The steps in this Owner’s Manual show only the label on

the key appropriate to the action being performed.

VOLUME Turns the scanner on or off and adjusts the volume.

SQUELCH Adjusts the scanner’s squelch.

20-430.fm Page 12 Wednesday, August 4, 1999 1:29 PM

PRIORITY/SPEED Sets and turns on and off the priority feature; turns the

HyperSearch mode on and off.

Number Keys Each key has a single-digit label and a range of num-

bers. The single digits are used to enter a channel,

frequency, or ID number. The range of numbers (31–

60, for example) indicates the channels that make up

a memory bank.

20-430.fm Page 15 Wednesday, August 4, 1999 1:29 PM

UNDERSTANDING

BANKS

Channel Storage Banks

To make it easier to identify and select

the channels you want to listen to,

channels are divided into 10 banks of

30 channels each. Use each channel-

storage bank to group frequencies,

such as those used by the police de-

partment, fire department, ambulance

services, or aircraft (see “Guide to the

Action Bands” on Page 39). For exam-

ple, the police department might use

four frequencies, one for each side of

town. You could program the police

frequencies starting with Channel 1

(the first channel in bank 1) and pro-

gram the fire department frequencies

starting with Channel 31 (the first

channel in bank 2).

Service Banks

The scanner is preprogrammed with

the frequencies allocated by public

safety, police, fire/emergency, aircraft,

and weather services. This is handy

for quickly finding active frequencies

instead of searching through an entire

band (see “Searching Service Banks”

on Page 18).

UNDERSTANDING

TRUNKING

In the past, groups that broadcast fre-

quently, such as police departments,

were restricted to transmitting on just

a few frequencies. This resulted in

heavy traffic and often required 2-way

radio users to wait for a specific fre-

quency to clear before transmitting.

Trunked systems allow more groups

of 2-way radio users to use fewer fre-

quencies. Instead of selecting a spe-

cific frequency to transmit on, a

trunked system chooses one of sever-

al frequencies when the 2-way radio

user presses PTT (push to talk). 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 data channel.

You can set this scanner to monitor

the data channel frequency, so you

can hear both the call and response

transmissions for that 2-way radio

user and therefore follow the conver-

sation. (You cannot listen to the data

channel itself in the trunk mode.)

20-430.fm Page 16 Wednesday, August 4, 1999 1:29 PM

OPERATION

TURNING ON THE

SCANNER AND SETTING

SQUELCH

1. Turn SQUELCH and VOLUME fully

counterclockwise.

2. Turn VOLUME back clockwise until

you hear a hissing sound.

3. Turn SQUELCH clockwise, then

leave it set to a point just after the

hissing sound stops.

Notes:

• If the scanner will not scan, turn

SQUELCH further clockwise.

• If the scanner picks up unwanted,

partial, or very weak transmis-

sions, turn SQUELCH clockwise to

decrease the scanner’s sensitivity

to these signals. If you want to lis-

ten to a weak or distant station,

turn SQUELCH counterclockwise.

•If SQUELCH is adjusted so you

always hear a hissing sound, the

scanner does not scan properly.

STORING KNOWN

FREQUENCIES INTO

CHANNELS

Good references for active frequen-

cies are the RadioShack “Police Call

Guide including Fire and Emergency

Services,” “Official Aeronautical Fre-

quency Directory,” and “Maritime Fre-

quency Directory.” We update these

directories every year, so be sure to

get a current copy.

Note: To store trunking system fre-

quencies, see “Programming Trunked

Frequencies” on Page 26.

Follow these steps to store frequen-

cies into channels.

1. Press MANUAL, enter the chan-

nel number (1–300) where you

want to store a frequency, then

press MANUAL again. The chan-

nel number appears.

2. Use the number keys and • to

enter the frequency (including the

decimal point) you want to store.

20-430.fm Page 17 Wednesday, August 4, 1999 1:29 PM

3. Press E to store the frequency into

the channel.

Notes:

• If you made a mistake in Step

2, Error appears and the

scanner beeps when you press

E. Simply start again from Step

• Your scanner automatically

rounds the entered frequency to

the nearest valid frequency. For

example, if you enter a fre-

quency of 151.473, your scan-

ner accepts it as 151.475.

• If you entered a frequency that

is already stored in another

channel, the scanner beeps

three times and displays the

lowest channel number where

the frequency is already stored.

If you want to store the fre-

quency anyway, press E again.

•Press

DELAY if you want the

scanner to pause 2 seconds on

this channel after a transmis-

sion ends before it proceeds to

the next channel (see “Delay”

on Page 21). The scanner also

stores this setting in the chan-

nel.

4. If you want to program the next

channel in sequence, press MAN-

UAL and repeat Steps 2 and 3.

SEARCHING SERVICE

BANKS

You can search for public service, po-

lice, fire/emergency, aircraft, and

weather transmissions even if you do

not know the specific frequencies that

are used in your area. And, you can

store any of the frequencies you find

into channels.

Your scanner has the following pre-

programmed service banks.

• PUBLIC — contains 140 public

service frequencies

• POLICE — contains 2,392 police

frequencies

• FIRE/EMG — contains 197 fire

and emergency service frequen-

cies

• AIR — contains 2,319 aircraft and

air service frequencies

• WX — contains 7 weather fre-

quencies

To select a service bank, press SVC. A

service bank’s name (PUB, PO-

LICE, FIRE/EMG, AIR, or WX) and

one of the preset public service fre-

quencies appear. After a 2-second de-

lay, searching begins.

SKIPPING DATA

SIGNALS

You can set the scanner so it skips

nonmodulated or data signals (such

as modem transmissions) during a

scan or search.

Note: Since data signals are not gen-

erally found in the air band, this fea-

ture does not work in the air service

bank.

TRUNK TRACKING

Your scanner is designed to track

transmissions on Motorola Type I,

Type II, and hybrid analog trunking

systems, which are extensively used

in 800 MHz communications. Remem-

ber these important points when track-

ing transmissions:

• Your scanner monitors Type II

systems by default. However, you

can change this if the system in

your area is different (see “Types

of Trunking Systems” on this page

and “Scanning Type I and Hybrid

Trunked Systems” on Page 33 for

more information).

20-430.fm Page 23 Wednesday, August 4, 1999 1:29 PM

PRIORITY

The priority feature lets you scan

through channels and still not miss im-

portant or interesting calls on specific

channels. You can program one

stored channel in each bank as a pri-

ority channel (for up to a total of 10

stored channels). As the scanner

scans the bank, if the priority feature is

turned on, the scanner checks the pri-

ority channel for activity every 2 sec-

onds.

The scanner automatically desig-

nates each bank's first channel as its

priority channel. Follow these steps to

select a different channel as the priori-

ty channel for a bank.

1. Press MANUAL.

2. Enter the channel number you

want to select as the priority chan-

nel, then press MANUAL again.

3. Hold down PRIORITY until the

scanner beeps twice. appears

to the right of the channel number.

4. Repeat Steps 2–3 for the channel

in each bank you want to program

as a priority channel.

To turn on the priority feature, press

PRIORITY during scanning. PRI ap-

pears. As you scan the bank, the

scanner checks the bank’s priority

channel every 2 seconds in each bank

that is turned on, starting from the low-

est to the highest-numbered priority

channel.

To turn off the priority feature, press

PRIORITY. PRI disappears.

Notes:

• The priority feature must be

turned off to use the data skip fea-

ture (see “Skipping Data Signals”

on Page 23).

• You can lock out priority channels.

If you lock out all priority channels,

CH Loc Out appears when

you turn on the priority feature.

• Your scanner cannot track trans-

missions on non-Motorola trunking

systems.

• Your scanner tracks an 800 MHz

trunked system

scans frequen-

cies in conventional mode, but it

cannot do both at the same time.

• The frequencies for many of the

800 MHz public safety systems are

listed in the separate “National

Public Safety Trunked System Fre-

quency Guide” included with your

PRO-2050.

20-430.fm Page 24 Wednesday, August 4, 1999 1:29 PM

TYPES OF TRUNKING

SYSTEMS

Your trunk tracking scanner can moni-

tor two basic types of systems —

Type

and

Type II

. Instead of selecting a

specific frequency to transmit on, a

trunked system chooses one of sever-

al frequencies in a 2-way radio user’s

talk group when that user presses

PTT (push to talk). Thus, trunking sys-

tems allocate a few frequencies

among many different users, but the

way Type I and Type II systems do

this is slightly different. One important

distinction between these systems is

the amount of data transmitted by

each radio when its PTT button is

pressed. In a Type I system, the ra-

dio’s ID and its current affiliation (the

trunk system it belongs to) are both

transmitted. In a Type II system, only

the radio’s ID is transmitted.

Why the difference? In Type I sys-

tems, each radio in the trunk group in-

dividually transmits its own affiliation,

while the trunk system maintains a da-

tabase that determines each radio's

affiliation(s) in Type II systems.

Another difference between the sys-

tems is that Type I systems are ar-

ranged in a fleet-subfleet hierarchy.

For example, it is possible for a city

using a Type I system to designate 4

fleets, each with 8 subfleets.

The fleets might be the police depart-

ment, the fire department, utilities, and

city administration. The police might

decide to further divide its fleet into

subfleets such as dispatch, tactical

operations, detectives, north, south,

east and west side patrols, and super-

visors. All the available police radios

would then be assigned to one of the

police subfleets, letting the police cen-

tralize their communications and con-

trol the type of users on a single

system. Determining the exact fleet-

subfleet hierarchy for a particular area

is referred to as

fleet map program-

ming

The disadvantage of a Type I system

is that the brief burst of data sent

when a user transmits must contain

the radio’s ID and its fleet and sub-

fleet. This is three times the amount of

data a Type II system radio sends.

Since the data capacity of Type I sys-

tems is limited and the amount of data

increases with each user, Type I sys-

tems usually accommodate fewer us-

ers than Type II systems. Never-

theless, Type I systems are still in use.

There are also

hybrid

systems which

are a combination of both Type I and

Type II. Your scanner defaults to mon-

itor Type II systems, but you can

change to Type I or a hybrid of Type I

and Type II systems by selecting a

preprogrammed fleet map or creating

a custom fleet map for your area (see

“Scanning Type I and Hybrid Trunked

Systems” on Page 33).

You do not need to determine the

fleet-subfleet hierarchy for Type II sys-

tems unless you are tracking hybrid

systems that contain both Type I and

Type II systems.

SETTING THE SCANNER

TO THE TRUNK

TRACKING MODE

Press TRUNK to switch between the

scanner’s conventional and trunk

tracking modes.

SETTING SQUELCH FOR

THE TRUNK TRACKING

MODE

Your scanner’s squelch setting is au-

tomatically adjusted in the trunking

mode, which means you do not need

to manually adjust squelch while

tracking trunked transmissions. How-

ever, the squelch setting can affect

how fast your scanner acquires the

data channel, and, in some instances,

can prevent your scanner from acquir-

ing the data channel at all.

We recommend you set SQUELCH to

this position before selecting a trunked

bank.

Note: You can change this setting, if

necessary, to provide better perfor-

mance in your area.

PROGRAMMING

TRUNKED

FREQUENCIES

Before you program your scanner to

track a trunked system, consider the

following:

• Valid trunked system frequencies

range from 851.0000–868.9875 in

12.5 kHz steps.

• You can use any of your scanner’s

banks as either a trunk tracking

bank or conventional scanning

bank, but you cannot mix the two.

• The scanner only scans one

trunked system at a time. Al-

though you can store frequencies

for more than one trunked system

in one of your scanner’s banks,

the scanner only scans the fre-

quencies associated with the first

data channel it finds.

Before scanning a trunked system’s

transmissions, you must store the

trunked system’s frequencies in one of

the banks in your scanner by following

these steps.

1. Hold down TRUNK until the scanner

beeps twice. BANK, TRUNK, and

the bank numbers flash.

20-430.fm Page 26 Wednesday, August 4, 1999 1:29 PM

2. Select the bank you want to store

the trunked system’s frequencies

in by pressing a number key. The

scanner automatically selects the

first channel in the bank.

3. Use the number keys to enter the

trunked system’s frequencies,

then press E.

4. Note: If you entered an invalid fre-

quency in Step 3, the scanner

beeps, the channel number

flashes and Error appears. If

this happens, press CLEAR to

clear the frequency, then repeat

Step 3.

5. Press either MANUAL or s to

select the next channel in the

bank.

6. Repeat Steps 3 and 4 until all fre-

quencies have been entered.

SCANNING A TRUNKED

BANK

You can scan one trunked bank at a

time. Once you have stored frequen-

cies for a trunked system in one or

more of the 10 available banks and

you are scanning non-trunked fre-

quencies, follow these steps to begin

trunk scanning.

1. Press TRUNK. The indicators for

all banks flash.

2. Use the number keys to enter the

number for the trunked bank you

want to scan, then press SEARCH

to begin searching for the trunk’s

data channel (the channel that

controls the trunk). SEARCH

flashes as the scanner searches

for a data channel. When the

scanner finds it, it begins trunk

tracking.

If you entered all of the trunk’s fre-

quencies, you should be able to

follow conversations between

broadcasters even when they

change frequencies. IDs, which

represent different service groups,

appear.

20-430.fm Page 27 Wednesday, August 4, 1999 1:29 PM

Note: To see the bank currently in

use for about 5 seconds, press

DATA while in the trunk tracking

mode.

3. To return to conventional scan-

ning, press TRUNK again.

Hint: While scanning, you will not

know exactly whom the IDs are as-

signed to until you listen awhile or until

you locate ID lists in frequency guides

or on internet sites such as

www.trunkscanner.com

. Within a few

minutes, you can usually figure out if

what you are listening to is a police,

fire, or emergency medical 2-way ra-

dio user. Other IDs might take some

time, but determining whom each ID

represents is half the fun of trunk

tracking!

Monitoring an Active ID

When the scanner stops on a trans-

mission, you can hold the scanner on

that transmission.

1. Press HOLD. HOLD appears and

the scanner stays on the current

ID.

2. If you want to listen to a different

ID, use the number keys to enter

the ID you want to hold. LIST 1

appears

3. Press HOLD again. HOLD flashes

and the scanner monitors that ID.

4. When you want to stop the hold

and resume searching for a data

channel so you can continue trunk

tracking, press SEARCH.

Note: You can also follow these steps

to hold on an ID while scanning a scan

list. See “Scan Lists” on Page 31.

Locking Out IDs

As with conventional scanning, it is

possible to lock out unwanted traffic.

This is particularly important in trunk-

ed systems because signals you can-

not listen to (such as water meters,

door alarms, traffic signals, and en-

crypted signals) are assigned IDs just

like other users. You can have up to

100 IDs locked out at one time.

Note: If you lock out an ID while

searching, it is also locked out of the

scan list(s). See “Scan Lists” on

Page 31.

20-430.fm Page 28 Wednesday, August 4, 1999 1:29 PM

To lock out an ID, press L/O when the

ID appears.

The ID is locked out, and the next ac-

tive ID appears.

Unlocking a Single ID

1. Hold down L/O until you hear two

short beeps.

2. Repeatedly press t or s to select

the ID you want to unlock.

3. Press L/O.

The ID is unlocked and the next

locked ID appears.

4. Press SEARCH to continue the

scanner’s previous function.

Unlocking All IDs

Hold down L/O until you hear two short

beeps. Then press E to unlock all the

IDs at once.- The scanner beeps

twice.

Note: When you unlock all the IDs,

the scan list mode appears. Press

SCAN to scan the IDs stored in your

scan lists or press SEARCH to contin-

ue the scanner’s previous function.

For more information about scan lists,

see “Scan Lists” on Page 31.

Using Trunk Tracking Scan

Delay

Many trunked systems have a period

of 2 or more seconds between a query

and a reply. You can program a 5-

second delay so the scanner holds on

an ID for 5 seconds to wait for a reply.

The scanner continues to monitor the

frequency for 5 seconds after the

transmission stops before resuming

scanning.

Press DELAY to turn trunk tracking

scan delay on or off. DELAY appears

when trunk tracking scan delay is set.

Note: If you consistently miss re-

sponses even with trunk tracking scan

delay set, you might need to change

the default system type or the fleet

map you are using. See “Scanning

Type I and Hybrid Trunked Systems”

on Page 33.

20-430.fm Page 29 Wednesday, August 4, 1999 1:29 PM

Monitoring IDs

You can use your scanner’s display to

monitor the frequencies in a trunked

system for activity. You cannot hear

conversations in this mode, but this is

an excellent way to determine which

talk groups are the most active. To set

the scanner to monitor IDs, hold down

SEARCH until the scanner beeps

twice.

SEARCH flashes, and all active

talk group IDs appear in succession.

To stop monitoring IDs, press

SEARCH again.

Note: When you monitor IDs, locked-

out IDs also appear.

CHANNEL ACTIVITY

INDICATORS

Your scanner has 30 channel activity

indicators (bars) which show the activ-

ity taking place on a trunked system.

You can see how many frequencies

are being used and generally monitor

how much communication traffic is oc-

curring.

Each frequency you store in a trunking

bank has a corresponding activity indi-

cator.

• The indicator that remains on

steadily even when there are no

current transmissions represents

the frequency being used as the

data channel.

• The indicator that flashes when an

ID appears represents the fre-

quency being used by the radio

you are currently hearing.

• If an indicator turns on but you do

not hear a conversation, the chan-

nel is probably being used for a

telephone interconnect call or a

private call, or the indicator might

be a locked-out ID. Your scanner

does not monitor these types of

calls.

• If the scanner is holding on an ID

which is not active, the other activ-

ity indicators turn on and off as

other groups use the system.

20-430.fm Page 30 Wednesday, August 4, 1999 1:29 PM

SCAN LISTS

When you program trunked frequen-

cies into a bank (see “Programming

Trunked Frequencies” on Page 26),

your scanner sets up 5 scan lists into

which you can store your favorite IDs.

Each list can contain up to 10 IDs, so

you can store a total of 50 IDs for each

trunk tracking bank (500 IDs if you use

all banks as trunking banks!).

Scan lists help you organize trunking

system users into categories. For ex-

ample, you might use List 1 for police

IDs, List 2 for fire department IDs, List

3 for emergency medical service IDs,

and so on. Once IDs are stored in

lists, you can scan them like you scan

conventional channels. You can pro-

gram IDs into scan lists manually, dur-

ing a search, or automatically.

Manually Storing IDs into

Scan Lists

1. Select the trunking bank you want

(see “Scanning a Trunked Bank”

on Page 27).

2. After the scanner begins trunk

tracking, press MANUAL. A scan

list number appears at the top of

the display, and a bar shows the

channel activity.

3. Repeatedly press s or t to select

the scan list location (shown at the

top of the display) you want to

program.

4. Enter the Type II ID you want to

store, then press E.

Or, to enter a Type I ID:

a. Use the number keys to enter

the block number and the fleet

number, then press •.

b. Enter the subfleet number, then

press E.

Note: To clear a mistake while

entering an ID, press CLEAR, then

start over at Step 4.

5. Repeatedly press MANUAL or s to

select the next scan list location

you want to program. Then repeat

Step 4 to enter another ID.

lists you have programmed. SCAN

scrolls on the display.

Note: If you haven’t programmed any

IDs, SCAN scrolls on the display but

your scanner does not stop on an ac-

tive conversation.

Scan List Location

20-430.fm Page 32 Wednesday, August 4, 1999 1:29 PM

To remove a scan list from active

scanning, use the number keys to en-

ter the scan list’s number. The scan

list indicator turns off, and the IDs in

that list are not scanned.

Note: You cannot remove all the scan

lists. One scan list must always be ac-

tive.

To restore a scan list to active scan-

ning, use the number keys to enter its

number again.

Press SEARCH to return to the scan-

ner’s previous function.

SCANNING TYPE I AND

HYBRID TRUNKED

SYSTEMS

Your PRO-2050 is set to scan Type II

user IDs by default. When you scan

trunked frequencies, each Type II user

ID you see appears as an even num-

ber without a dash (such as 2160).

Your PRO-2050 can also scan Type I

trunked systems. Each Type I ID ap-

pears as a three- or four-digit number,

followed by a hyphen, followed by a

one- or two-digit number (such as

200-14).

If you notice a mix of odd- and even-

user IDs (such as 6477, 2160, 6481,

6144, and 1167), then you are proba-

bly monitoring either a Type I or hybrid

(a combination of Type I and Type 2

user IDs) system. (See “Types of

Trunking Systems” on Page 25.)

You might also notice that you are

missing responses when you hold on

an active ID. Unlike Type II systems,

Type I and hybrid systems require a

fleet map that sets specific fleet-sub-

fleet parameters. It is easy to select a

fleet map to scan; what is not always

easy is selecting or programming a

map that is being used in your particu-

lar area.

When a Type I system is designed,

the address information for all its user

IDs is divided into 8 equal-size blocks,

numbered 0–7, and each block is as-

signed a size code. When you set up

your scanner to track a Type I system,

you must choose a size code for each

block. When you have chosen a size

code for all 8 blocks, you will have du-

plicated the

fleet map

for the system

you are tracking. If you have chosen

correctly, you will be able to track

transmissions in that system.

Each size code defines the number of

fleets, subfleets, and IDs each block

has. For example, you can see in the

following table that a size code of S4

has one fleet, which is divided into 16

separate subfleets, and it has a total

of 512 individual IDs.

Size Fleets Sub-

fleets IDs Block

Used

S0 Reserved block for Type II IDs

S1 128 4 16 1

20-430.fm Page 33 Wednesday, August 4, 1999 1:29 PM

S2 16 8 64 1

S3 8 8 128 1

Each ID in the block is unique. The

left-most digit is the block number in

the ID. The next two digits identify

which fleet is active, and the last dig-

it(s) (after the hyphen) identifies the

subfleet.

The size codes selected by a Type I

system designer depend on the spe-

cific needs of the system’s users.

Some organizations might want many

subfleets with only a few radios each,

while another organization might want

only a few subfleets, with many radios

each. To scan Type I systems, you

must select or program a fleet map

with the same size code assignments

as the trunked system. If you do this

accurately, you will track all the fleet

and subfleet combinations used by the

system. In other words, you will hear

complete communications while moni-

toring a trunked system.

ure out all the blocks at once, this is

not as hard as it seems. Select a size

code for a block, then press SEARCH.

Now listen to the communications. If

you decide you are receiving most of

the replies to the conversations with

IDs assigned to the block you just pro-

grammed, then you have probably se-

lected the right size code and can

work on the next block of the map.

There are 16 preset fleet maps to

choose from, and it is best to start with

these when setting up a Type I or hy-

brid trunk tracking bank. If none of the

following preset fleet maps allow you

to follow complete conversations, then

you probably need to program your

own fleet map (see “Programming a

Fleet Map” on Page 36)

Selecting a Preset Fleet Map

1. Press SCAN, then hold down

TRUNK until the scanner beeps

twice. BANK, TRUNK and the

bank numbers flash.

2. Select the bank where you want to

store the preset fleet map by

pressing a number key.

3. Press DATA.

4. Repeatedly press s or t to select

E1 (Type I and hybrid), then press

DATA again.

Note: To select Type II, press E

when E2 appears.

5. Repeatedly press s or t to select

the name of the map you want

(such as E1P7), then press E.

The scanner then searches for trans-

missions using the preset map you

chose.

Note: When the scanner searches for

transmissions, you see Type I fleet

and subfleet IDs such as 100-12,

100-9, 000-12, or 400-8.

How do you know if the preset map

you selected is correct? Listen to see

if you are following complete conver-

sations. If not, try another preset map.

5. Repeatedly press s or t until USr

appears.

6. Press DATA.

7. Repeatedly press s or t to select

the size code for the first block,

then press E. The next available

block appears.

8. Repeat Step 7 until you have

selected a size code for each

block you want to work with.

9. Press SEARCH. The scanner exits

the trunking programming mode,

tunes the data channel, then

begins to search using the map

you programmed.

Note: If you select size code S12,

S13, or S14, these restrictions apply:

• S12 can only be assigned to

Blocks 0, 2, 4, or 6.

• S13 can only be assigned to

Blocks 0 and 4.

• S14 can only be assigned to Block

Since these size codes require multi-

ple blocks, you will be prompted for

the next available block when pro-

gramming a fleet map. For example, if

you assign Block 0 as an S12, the

scanner prompts you for b2, the next

block available, instead of b1. And if

you assign Block 0 as an S14, you

would not see another prompt be-

cause it uses all available blocks.

PROGRAMMING A

HYBRID SYSTEM

A hybrid system is simply a Type I

system with some of its blocks desig-

nated as Type II blocks. To program a

hybrid system, follow the steps listed

in “Programming a Fleet Map.” How-

ever, if you want a block to be Type II,

select size code S0 in Step 7.

Reception of the frequencies covered

by your scanner is mainly “line-of-

sight.” That means you usually cannot

hear stations that are beyond the hori-

zon.

GUIDE TO

FREQUENCIES

National Weather

Frequencies

Canadian Weather Frequencies

Note: These three frequencies are not

pre-programmed in the weather ser-

vice bank but can be manually pro-

grammed into a channel.

Birdie Frequencies

Every scanner has birdie frequencies.

Birdies are signals created inside the

scanner’s receiver. These operating

frequencies might interfere with

broadcasts on the same frequencies.

If you program one of these frequen-

cies, you hear only noise on that fre-

quency. If the interference is not

severe, you might be able to turn

SQUELCH clockwise to cut out the

birdie. This scanner’s birdie frequen-

cies (in MHz) are:

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 near-

by 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 high-

est. 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.
