Your new RadioShack PRO-2050 VHF/UHF/Air/800MHz 300-Channel TrunkTracker Home Scanner is one of a new generation of scanners de­signed to track Motorola Type I, Type II (such as Smartnet and Priva­cy Plus), and hybrid analog trunking systems, which are extensively used in many 800 MHz 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, an d also sends a code that uniquely identifies that 2­way radio user’s transmission on a dif­ferent frequency called a data chan­nel.
Since the trunking sy stem 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-2050 monitors the data channel frequency sent with a 2-way radio user’s transmission and instantly switches to an active fre­quency, so you c an 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. B y 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 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 easi­ly identify calls.
Five Scan Lists
— let you st ore u p t o 50 IDs in each tracking bank (up to a total of 500).
Triple-Co nversion Circ uitr
— 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 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 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.

SCANNING LEGALLY
Scanning is a fun and interesting hob­by. You can hear police and fire de­partments, ambulance services, government agencies, private compa­nies, 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 in­tentionally intercept. These include:
• Telephone conversations (cellu­lar, cordless, or other private means of telephone signal trans­mission)
• Pager transmissions
• Scrambled or encrypted transm is­sions
According to the Federal Electronic Communications Privacy Ac t (ECPA), as amended, you c ould be fined and possibly imprisoned for intentionally intercepting, using, or disclosing the contents of such a transmission un­less you have the consent of a party to the communication (unless such activ­ity is otherwise illegal). These laws change from time to time and there might be state or lo cal laws that also affect legal scanner usage.

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 B NC connector. Your local RadioShack store sells a variety of antennas. Choose the one that best meets your needs.
When deciding on a mobile or base­station antenna and its locat ion, con­sider these points:
g
20-430 .fm Page 9 Wednesday, A ugust 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 sup­plied antenna from the scanner. Al­ways 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 low­loss dielectric coaxial cab le. If the an­tenna cable’s connector does not fit in

jack on the
back of the scanner.
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.
Use extreme caution
Warnin
:
when you install or remove an out­door antenna. If the antenna starts to fall, let it go! It could contact overhead power lines. If the anten­na touches a power line, contact with the antenna, mast, cable, or guy wires can cause electrocution and death. Call the power compa­ny 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 back of the scanner, then plug the AC adapter into a standard AC outlet.

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 dis­connect the AC a dapter from the AC outlet before you d isconnect it from the scanner.
Warning: Do not use the AC adapt­er’s polarized plug with an extension cord receptacle unless the blades can be fully inserted to preven t blade ex­posure.
Using Your Vehicle’s Battery Power
ANT
DC 12V
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 cor­rectly fit the
DC 12V
jack on the back of the scanner. The recom­mended power cable mee ts 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 vehicl e’s engine is running, you might hear electrical noise from the engine w hile s can­ning. This is normal.
If your AC power fails (during an emergency, for example), you can power your scanner from your vehi­cle’s cigarette lighter socket with an optional DC cigarette lighter power ca­ble, 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.

Listening Safely
To protect your hearing, follow these guidelines when you use an earpho ne or headphones.
• Do not listen at extremely high volume levels. Extended high­volume listening can lead to per­manent hearing loss.
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 inch plug (such as Cat. No. 33-175 or 20-210) to the jack on the front of the scanner. This automatically dis­connects the internal speaker.

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 channel­storage bank to group frequencies, such as those used by the police de­partment, fire department, am bulance services, or aircraft (see “Guide to the Action Bands” on Page 39). For exam­ple, 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 pro­gram the fire department f requencies 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, gro ups that broad cast fre­quently, 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 fre­quency to clear before transmitting.
Trunked systems allow more groups of 2-way radio users to use fewer f re­quencies. Instead of selecting a spe­cific frequency to transmit on, a trunked system chooses one of sever­al frequencies when the 2-way radio user presses PTT (push to talk). The system automatically transmits the call on that f requency, 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 conver­sation. (You cannot listen to the data channel itself in the trunk mode.)

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. Remem­ber these important points when track­ing transmissions:
Note:
You can use HyperSearch only in the 5 kHz step bands (29–54 MHz and 137–174 MHz).
• 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).

TYPES OF TRUNKING SYSTEMS
Your trunk tracking scanner can moni ­tor two basic types of systems —
I
Type II
and specific frequency to transmit on, a trunked system chooses one of sev er­al frequencies in a 2-way radio user’s talk group when that user presses PTT (push to talk). Thus, trunking sys­tems allocate a few frequencies among many different users, but the way Type I and Type II systems do this is slightly d ifferent. O ne import ant 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 ra­dio’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 sys­tems, each radio in the trunk group i n­dividually transmits its own affiliation, while the trunk system maintains a da­tabase that determines each radio's affiliati o n (s) in Type II systems.
Another difference between the sys­tems is that Type I systems are ar­ranged 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 migh t be the po lice depart­ment, the fire department, utilities, and city administration. The police might decide to further divide its fleet into
. Instead of selecting a
Type
subfleets such as dispatch, tactical operations, detectives, north, south, east and west side patrols, and super­visors. All the available police radios would then be assigned to one of the police subfleets, letting the police c en­tralize their communications and con­trol the type of users on a single system. Determining the exact fleet­subfleet hierarchy for a part icular area is referred to as
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 sub­fleet. This is three times the amount of data a Type II system radio sends. Since the data capacity of Type I sys­tems is limited and the amount of data increases with each user, Type I sys­tems usually accommodat e fewer us­ers than Type II systems. Never­theless, Type I syst ems are still i n use.
There are also are a combination o f both Type I a nd Type II. Your scanner defaults to mon­itor 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 o r creating a custom fleet map for your area (see “Scanning Type I and Hy brid Trunked Systems” on Page 33).
You do not need to determine the fleet-subfleet hierarchy for Type II sys­tems unless you are tracking hybrid systems that contain both Type I and Type II systems.

PROGRAMMING TRUNKED FREQUENCIES
Before you program your scanner to track a trunked system, consider the following:
• Valid trunked system frequencies range from 85 1.00 00–868 .987 5 i n
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. Al­though you can store frequencies for more than one trunked s ystem in one of your scanner’s banks, the scanner only scans the fre­quencies 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.

SCAN LISTS
When you program trunked frequen­cies 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 t o 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 trunk ing 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 pro­gram IDs into scan lists manually, dur­ing a search, or automatically.

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 num­ber without a dash (such as 2160). Your PRO-2050 can al so scan Type I trunked systems. Each Type I ID ap­pears as a three- or four-dig it num ber, followed by a hyphen, followed by a one- or two-digit number (such as 200-14).
If you notice a mix of odd- and even­user IDs (such as 64 77, 2160, 6481, 6144, and 1167), then you are proba­bly 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-sub­fleet parameters. It is easy to select a fleet map to sc an; what is not always easy is selecting or programming a map that is being used in your particu­lar area.
When a Type I system is designed, the address information for all its us er IDs is divided into 8 equal-size blocks, numbered 0–7, a nd each block is as­signed a size code. When you set up your scanner to track a Type I syst em, you must cho ose a size code for each block. When you have chosen a size code for all 8 blocks, you will ha ve du­plicated the you are tracking. If you have chosen correctly, you will be able to track transmissi ons in that system.
Each size code defines th e 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.

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 dig­it(s) (after the hyphen) identifies the subfleet.
The size codes s elected by a Type I system designer depend on the spe­cific needs of the system’s users. Some organizations might wa nt many subfleets with only a few radio s each, while another organization mig ht want only a few subfleets, with m any 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. I n other words, you w ill hear complete communicat ions whi le m oni ­toring a trunked system.
If you do not already know the size codes used, you will have to guess them. But since you do not have to fig­ure 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 rec eiving most of the replies to the conversations with IDs assigned to the block you just pro­grammed, then you hav e probabl y se­lected 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 T ype I or hy­brid 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)

PROGRAMMING A HYBRID SYSTEM
A hybrid system is simply a Type I system with some of its blocks desig­nated as Type II blocks. To program a hybrid system, follow the steps listed in “Programming a Fleet Map.” How­ever, if you want a block to be T ype I I, select size code

A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly “line-of­sight.” That means you usually cannot hear stations that are beyond the hori­zon.
GUIDE TO FREQUENCIES
National Weather Frequencies
162.400 162.475 162.525 162.425
162.500 162.550 162.450
Canadian Weather Frequencies
161.650 161.775 163.275
Note:
These three frequencies are not pre-programmed in the weather ser­vice bank but can be manually pro­grammed 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 s ame frequencies. If you program one of these frequen­cies, you hear only noise on that fre­quency. If the interference is not severe, you might be able to turn

clockwise to cut out the
171.25 406.7625 407.8125 413.175 413.225
To find the birdies in your individual scanner, begin by disconnecting the antenna and movin g 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.

FREQUENCY CONVERSION
The tuning location of a station can be e xpressed in frequency (kHz or M Hz) 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:
9.62 (MHz) ¥ 1000 = 9620 kHz
To convert from kHz to MHz, divide the number of kilohertz by 1,000:
2780 (kHz) ÷ 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz:
300 ÷ 7.1 MHz = 42.25 meters

CARE AND MAINTENANCE
Your RadioShack PRO-2050 VHF/UHF/Air/800MHz 300-Channel TrunkTracker Home Scanner is an example of superio r design and craftsmanship . The following suggestions will help you care for your scanne r so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.
Handle the scanner gently and carefully. Dropping it can damage cir­cuit boards and cases and can cause the scanner to work improperly.
Use and store the scanner only in normal temperature environments. Temperature extremes c an shorten the life of electron ic devices and distort or melt plastic parts.
Keep the scanner away from dust and dirt, which can cause premature wear of parts.
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 sc anner’s internal components can caus e a mal­function and might inv alidate the s canne r’s warrant y and void your FCC authoriza­tion to operate it. If your scanner is not operating as it should, take it to your local RadioShack store for assistance.
