Features

Your RadioShack Handheld Scanner is one of a new generation of scanners desig ned to track Motorol a I and Type II (such as Smartnet hybrid analog trunking systems, plus GE/Ericsson (EDACS®) and EF Johnson (LTR®) type systems, wh ich are extensively used in many communication systems.

Trunking comm uni ca tions systems let a large group of 2way radio users (or even different groups of 2-way radio users) efficiently use a set of frequencies. Instead of selecting a specific frequency for a transmission, the 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 transmission .

Since the trunking system might send a call and its response on different frequencies, it is difficult to listen to trunked communications using a regular scanner. The scanner monitors the data sent with a 2-way radio transmission, so you can hear the call and response for that user and more 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 an d o t he r ag enc ie s w i tho ut t edi ous an d complicated programming.

CONNECTING AN EARPHONE/ HEADPHONES

For private listening , you can plug an earph one or m on o/ stereo headphone s (not s upplied), available at y ou r l ocal RadioShack store, into the jack on top of your scanner. This automatically disconnects 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 permanent hearing loss.

Preparation

20-522b.fm Page 17 Thursday, September 7, 2000 9:41 AM

• Set the volume to the lowest setting before you

begin listening. After you begin listening, adjust the volume to a comfortable level.

• Once you set the volume, do not increase it. Over

time, your ears adapt to the volume level, so a volume level that does not caus e disco mfort might st ill damage your hearing.

Traffic Safety

Do not wear an e arph one or headphone s whil e you drive a vehicle or ride a bicycle. This can create a traffic hazard and can be illegal in some areas.

Even though some earphones and headphones let you hear some outside sounds when you listen at normal levels, they still can present a traffic hazard.

CONNECTING AN EXTENSION SPEAKER

In a noisy area, an amplified speaker (not supplied), available at your local RadioS hack store, might provide more comfortable listening. Plug the speaker cable’s inch (3.5-mm) mini-plug into your scanner’s jack.

Note:

You must use an am pli fied speaker with this s ca nner. Non-amplified speakers do not provide sufficient volume for c omfortable listening.

USING THE BELT CLIP

You can use the belt clip attached to the back of the scanner for hands-free carrying when you are on the go. Slide the belt clip over your belt or waistband.

Preparation

20-522b.fm Page 18 Thursday, September 7, 2000 9:41 AM

CONNECTING THE CLONE CABLE

You can transfer the programmed data to and from another PRO-92 or PRO-2067 using the supplied clone cable. Connect the cable between each scanner’s PC/IF jacks.

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 (0–

9) of 50 (00 to 49) channels each. Use each channelstorage bank to group frequencies, such as those used by the police department, fire department, ambulance services, or aircraft (see “Typical Band Usage” on Page 61). 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 1st digit identifies the bank (0–9). The 2nd and 3rd digits identify the channel within the bank (00–49).

Search Banks

This scanner is abl e to search 10 sea r ch ba nk s. You can also replace a bank wi th one o f the pre-prog rammed s ervice bands. (For the default setting, see “Searching a Preprogrammed Frequency Range” on Page 34.)

Note:

You can increase the number of preprogrammed frequency ranges your scanner can receive (up to 100) using an optional PC interface kit (available at your local RadioShack store).

UNDERSTANDING CTCSS/DCS

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 codes.

When your scanner receive s a CTCSS tran smis sion, (private line) appears. When your scanner receives a

DPL

DCS transmission, it code appear.

PL Codes

PL codes are low-freq uen cy audio tones that are us ed to differentiate different users on the same channel. PL codes appear according to the EIA standard CTCSS tones, and range from 67.0 Hz to 254.1 Hz. PL codes are displayed directly as a frequency.

DPL Codes

DPL codes are similar to PL codes , excep t they migh t be transmitted as either tones or digital codes. Although there are as many as 4096 DPL codes, only about 100 are actually used.

DPL codes appear in the format an octal code.

UNDERSTANDING YOUR SCANNER’S MODES

You can program each channel with any of seven receive modes . Each mo de affect s how your scanner operates when scanning and receiving transmissions, and also affects what transmissions you receive when you set the scanner to the closed mode (see “Open and Closed Modes” on Page 57). The following sections describe each mod e and how they a ffect yo ur sc ann ers o peration. See “Changing the Receive Mode” on Page 45.

PL, DPL and trunking systems all use some form of

squelch

mission of a special “code” signal along with the audio of a radio transmission. A receiver with coded squelch only activates when the received signal has the correct “code.” This lets many users share a single frequency, and decreases interference caused by distant transmitters on the same channel.

In all major metropolitan areas of the United States, every available radio channel is assigned to more than one user. Public safety radio systems on the s ame fre que nc y are usually set up at a distance of 40 miles apart, or more. This means that you may hear transmissions from a distant system when your local system is not transmitting. By entering th e PL fo r a local system, and o perating the bank in closed mode, t he scanner will not stop on transmissions from the distant system.

With few exceptions, such as the VHF Aircraft and Marine bands, almost ev ery oth er VHF or U HF radio s ystem uses some form of coded squ elc h. By far, PL is th e mos t popular mode among non-trunked systems. For most scanning use, try setting PL mode for all non-trunked channels. If you operate the bank in open mode, the scanner will display the appropriate code.

You can set each of the scanner’s channel storage banks to open or closed mode.

In open mode, the scanner scans signals transmitted in all systems. In closed mode, the scanner scans signals transmitted only under the following conditions:

• When the signals are in the FM mode.

• When the signals are in the LT, MO, or ED mode

and

the signal's ID code matches the programmed

• When the signals are in the PL or DPL mode the signal's ID code matches the programmed ID code.

Note:

AM Mode

This sets the scan ner to receiv e trans miss ions us ing am plitude modulation (AM). AM is used for aircraft, military, some amateur radio, and some government transmissions. When the scanner receives a transmission on a channel set to the AM mode, it always stops on the transmission.

FM Mode

This sets the scanner to receive transmissions using frequency modulation (FM). FM is used for most public safety transmissions, as well as broadcast, business, and amateur radio transmissions. When the scanner receives a transmission on a channel set to the FM mode, it always stops on the transmission.

LTR (E. F. Johnson) Mode

You can set your scanner so it decodes the talk group IDs used with LTR systems. This setting is called the

LTR mode

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 where:

AHHUUU

= Area code (0 or 1)

= Home repeater (01 through 20)

= User ID (000 through 254)

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 Mod e

You can set your scanner so it decodes the talk group IDs used with Motorola trunking systems. This setting is called the

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 gr oup of u sers i n the s ystem is assi gned to a specific talk group. For example, the e as t si de p atro l 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 channel.

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 mode

Motorola trunking systems come in three categories:

Type I, Type II

plays and uses talk group IDs in slightly different ways. Motorola Type I IDs are in the form

FFF

= Fleet ID

= Subfleet ID

Type I systems are usually organized with different user groups assigned to different fleets. For example, a valid fleet/subfleet ID identifying all detectives within a police department might be police users and

widely available on the Internet for most Type I systems in use.

Type II system talk groups are identified by a 5-digit number. Valid talk group IDs are divisible by 16. If you try 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 5digit formats for talk group IDs.

Note:

EDACS Mode

You can set your scanner so it decodes the talk group IDs used with EDACS (GE/Ericsson) trunking systems. This setting is called the

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.

EDACS mode

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 a 4-digit decimal number from 0000 to 4095.

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 cl os ed mo de, the scanner onl y goe s to tran smissions with IDs that match talk group IDs you have stored in the bank’s talk group ID list which are 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

PRIORITY

With the priority feature, you can scan through programmed channels and still not miss an important or interesting call on a specific channel. When a channel is selected as the priority channel and priority is turned on, the scanner checks that channel every 2 seconds, and stays on the channel if there is activity until the activity stops.

The scanner is preset to select Channel 00 in Bank 8 as the priority channel. You can program a different channel as the priority channel. Also, you can program a weather channel as the priority channel.

Notes:

• The priority feature doe s not ope rate whil e the sca n-

• If you program a weather channel as the priority

channel, the scanner stays in the priority channel only when the scanner detects the weather alert tone.

Trunking Operation

The scanner tracks transmissions that use the Motorola Type I and Type II (such as Smartnet and Privacy Plus) and hybrid analog trunking systems, plus GE/Ericsson (EDACS) and EF Johnson (LTR) type systems, which are extensively used in many communication systems.

Trunking systems alloc ate a f ew fre quenc ies to m any d ifferent users. When the mobile unit transmits a signal, one frequency is chosen from among the allocated frequencies in that trunking system. The user’s

group

is sent with the signal.

To receive trunking signals, you must store all the trunking group frequencies in one bank (see “Storing Known Frequencies into Channels” on Page 30) and input ID

Trunking Operation

ID talk

codes in the ID memory (see “Storing Talk Group IDs” on Page 55). To listen to the transmission, the mode of the programmed channel must 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 g rou p 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.

Trunking group frequencies are included in the supplied

for example.

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 2way radio users to wait for a specific frequency to clear before transmitting. Trunked systems allow more groups of 2-way radio users to use few er freque ncies . Instea d of selecting a specific frequency to transmit on, a trunked system chooses one of several frequencies when the 2way radio user transmits. The system automatically transmits the call on that frequency, and also sends a code that ide ntifi es that 2- way radi o user’ s transmi ssion 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.

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 Motor-

ola 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 51 and “Locking Out Channels or Frequencies” on Page 41. Turn off the scanner to remove the lockouts.

• If you are programming trunked frequencies for

Motorola Type I and hybrid systems, you must first program the fleet map (see “Programming Fleet Maps” on Page 53).

• You must store frequencies using the subaudible

trunking method in banks, mode by mode.

Follow these steps to program trunked frequencies.

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 control channel. You must program th e sy s tem ’ s bas e fre quency 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 frequenci es.

FREQUENCY CONVERSION

The tuning l oca tio n of a st ati on c an be exp res sed in f requency (kHz or MHz) or in wavelength (meters). The following information can help you make the necessary conversions.

1 MHz (million) = 1,000 kHz (thousand)

A General Guide to Scanning

20-522b.fm Page 66 Thursday, September 7, 2000 9:41 AM

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 kilo-

hertz 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
