Easier to Read Pro-97/2055 Scanner Manual

These are another excellent set of radios that have many fine features for scanning and trunking. However, anyone who has tried to read the manuals that come with the radios know it can be a little hard (if you're lucky) to find, read, and figure out some of the steps, especially in the searching and trunking sections. IMHO they are a mess.

I can’t remember everything and find myself referring back to the manual for explanations of procedures and find it frustrating trying to figure out the wording every time. I decided to write and print this for myself to make it easier to use the radio and am happy to share it with you. This should also make it easier for most people to use some of the more advanced features of the radio (and get their money’s worth if you paid full-price for the radio new) as I will try to explain procedures a little more clearly and in a more logical order. Granted, these radios aren't simple so you will have to spend some time on them but this manual will at least make it easier. If you follow the red highlighted text in the programming sections, you should find what you need to know. If you want to find out what's really going on with the radio, read everything else.

I will assume you know how to obtain the basic information from the original manual such as following safety procedures, putting the batteries in, connecting the antenna, finding specs, etc. and concentrate on the main functions of the scanner.

Some of the better features of these radios are the ability to receive tone codes in certain service searches, the seek feature in search mode that resumes searching after 5 seconds, and the adjustable ID delay. IDs can be locked out in open mode. The first Military air HH in a while. The Skywarn lets you program 3 Skywarn frequencies (or any other conventional freqs) into channels 997-999 for one-touch access to them. The best one, in my opinion, is the ability to configure everything in the software, on the computer, and then just shoot it to the radio (with a one-way cable) or back to the computer (with a two-way cable). Much easier to work with the keyboard and see the monitor. You can set the attenuator globally or per channel. With a couple of keystrokes, you can view the IDs as text or code. There are 5 ID lists (30 IDs per list) to store 150 IDs for each bank. With the Win97 software, you can program any frequency from 5 kHz to 1.3 GHz, excluding cell.

Now, on the flip side, there are some pretty annoying things about these radios too. They still have preset steps that will not tune to many of the splinter frequencies in the VHF range (except the 108-137 air band) like 151.0125 (it accepts it as 151.01). The Air service search is relatively slow because of the 8.33 kHz steps. Still only 1 priority channel?

An overview of the features can also be view at my Trunking Radio Comparison Chart page.

These radios also have software that will enhance and/or enable other features not possible with just the keypad and have been noted when known. My opinion is get the Win97 software if you have a lot of frequencies. With all the features and setting in these new fangled devices it will save you hours of programming and frustration. It may also be easier to figure out the software than the keypad sequences. Alpha tagging is great but much easier with the software. Because of the limited amount of keys on the radios, programming a 3 letter word takes about 20 keystrokes on my Pro-97, if you can remember the sequence and don't make a mistake, after you program the bank name. See what I mean? Get the software. You have to dish out $20 bucks or so for a cable, the software is $25 (after a 30-day free trial), and there are plenty of newsgroups on the Net about these radios to help you hook up to the computer and work the software. You can find it here: Win97.

All in all, they will compliment your scanner collection (provided you have one).

I hereby absolve myself from anything that happens to anyone or the scanner as a result of the information you will be reading. You are welcome to copy and/or print these pages and use them in the scanning hobby as long as don't change them or charge anyone money for them.

Check back often as this document will be updated and revised from time to time.

Understanding Trunking

Contents

Trunking systems let a large group of 2-way 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’s radio selects a programmed trunking bank in the system when that user presses their PTT (push to talk) button. The trunking system automatically transmits the call on the first available frequency, and also sends (on a different frequency called a Data or Control channel) a code that uniquely identifies that transmission as a talkgroup ID (here after referred to as just ID). So when you are trunking a system, you are listening to active IDs transmitting in the system (each using the first available frequency in the system). Thus, trunking systems in general, allocate a few frequencies among many different users.

These trunking scanners trunk the three main types of systems; Motorola, Ericsson EDACS, and E.F. Johnson LTR systems. These scanners will not trunktrack the newer digital systems.

When you program a Motorola or EDACS frequencies into the scanner, one frequency is the data channel, and the rest are the frequencies shared by all the users. The data is continually transmitted to the field units and has a sound similar to listening to a boat engine over the phone (in manual mode; you won't hear this when you are trunking the system). This data channel is also a good check to see if you can trunk the system. If you can't hear a data channel when you step through the trunking frequencies (in manual mode), you either don't have all the frequencies or are too far away to receive the system. Motorola systems are limited to a maximum of 28 frequencies per system, Ericsson EDACS systems are limited to 25 frequencies per system.

LTR systems work a little differently. These systems encode all trunking information as digital subaudible data that accompanies each transmission. LTR systems typically do not have a dedicated control channel. Each repeater has its own controller, and all of these controllers are synchronized together. Even though each controller monitors it's own channel, one of the channel controllers is assigned to be a master that all controllers report to. Each of these controllers sends out a data burst approximately every 10 seconds so that the subscriber units know that the system is there. This data burst is not sent at the same time by all the channels, but happens randomly throughout all the system channels. If you listen to the frequencies of an LTR system in manual mode (not trunking), on every channel in the system you will hear this data burst that will sound like a short blip of static like someone keyed up and unkeyed a radio within about 500 msec. LTR systems are limited to 20 frequencies per system.

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. This scanner lets you select and monitor the data channel frequency sent with a 2-way radio transmission within the trunking bank, so you can hear calls and responses for users and more easily "follow" conversations than with a conventional scanner.

Trunkscanning is basically scanning IDs that are programmed into ID locations (same concept as frequencies into channels). You can then trunkscan just the programmed IDs. Trunking is searching for all IDs in a system (same concept as searching for frequencies in a band).

Radio Reference.com has an excellent page explaining the various types of trunking systems in more detail here.

Understanding Banks

Contents

Channel Storage Banks

The radios have 10 banks of 100 channels. Channel numbering starts with 000 and goes to 099 in the first bank. Banks number 0-9. You can also program your trunking frequencies and conventional frequencies into the same bank as well to utilize channel space better.

Use each channel-storage bank to group frequencies, such as those for police, fire, ambulance, aircraft, and/or trunking systems. For example, your police department might use 20 frequencies while the fire department uses 15 and a trunked EMS systems uses 5 trunked frequencies. You could program the EMS frequencies starting with channel 000, (the first channel in bank 0), the police frequencies starting with channel 005, and the fire department frequencies starting with channel 025. EDACS systems have to start at channels 001, 101, 201, etc. and follow a LCN order but you can still use 000, 100, 200, etc. for a conventional frequency.

For each trunking bank, you can put in one EDACS system (with conventional frequencies), or one Motorola system and/or an LTR system (with conventional frequencies). However, if you store a Motorola system and an LTR system in one bank, the bank mode has to be set to MO (Motorola). If it is set to LT (LTR), the Motorola control channel will break the squelch and hang the scanner on that channel.

Also,

(1) if you scan this bank in open mode, you will hear all Motorola IDs and LTR transmissions (IDs will be incorrect because the bank is set to receive Motorola IDs).
(2) If you scan this mixed bank in closed mode with Motorola IDs programmed, you will hear just the programmed Motorola IDs.
(3) You will hear the data bursts from the LTR system about every 5 seconds so you should set the delay for these channels accordingly.

Tip: Theoretically, you could also program more than one (of the same type i.e. Motorola) trunking system into a bank as long as you could only monitor one at a time, in different locations, far enough apart, so the system you are monitoring wouldn't interfere with the other system (which would confuse the radio). But remember, the scanner can be set to decode only one type of ID (MO, ED, or LTR) per bank.

Service Bands

The scanners also have 7 service bands pre-programmed with frequencies and 1 limit search to allow you to create your own search band. Search bands SR3 (Police/Fire), and SR5 (Ham) are divided into groups or sub-bands of frequencies that can be turned on or off within the bands.

Understanding IDs

Contents

Motorola IDs come in two formats: Type I and Type II. Each format displays and uses talk group IDs in slightly different ways.

Type I IDs are in the format FFF-SS where FFF is the fleet and SS is the sub-fleet. Type I systems are usually organized with different IDs assigned to different fleets. For example, a valid fleet/subfleet ID identifying all detectives within a police department might be 000-12, where 000 identifies all police IDs and 12 identifies the Detective division. To properly trunk a Type I system, you have to program the fleet map for the system.

Type II IDs are identified by a 5-digit number. Valid (programmable) talk group IDs are divisible by 16.

Type I/II hybrid systems use both Type I and Type II formats for talk group IDs.

EDACS IDs come in two formats: AFS (Agency-Fleet-Subfleet) and Decimal.

AFS IDs are in the form AA-FFS where AA is the agency, FF is the fleet, and S is the sub-fleet. EDACS systems are organized with different IDs assigned to different fleets and agencies. For example, a valid agency/fleet/subfleet ID identifying all detectives within a police department in an agency might be 06-101, where 06 identifies the agency (Police), 10 identifies the Police division (East side), and 1 identifies the Detective division.

Decimal IDs are shown as a decimal number from 0 to 2047.

You can find a chart showing Decimal and AFS equivalents here: Conversion Chart.

LTR IDS are in the format A-HH-UUU where A is the area code (0 or 1), HH is the home repeater (01-20), and UUU is the user ID (000-254).

Receive Modes

Contents

Each channel can have its own receive mode:
AM, FM (NFM), CT (CTCSS), DC (DCS), MO (Motorola), ED (EDACS), or LT (LTR) mode.

If the receive mode of the channel is set to CT, PL codes appear in the format xxx.x, where xxx.x is a frequency in Hz.

If the receive mode of the channel is set to DC, DPL codes appear in the format xxx, where xxx is an octal code.

AM - Receives AM transmissions.

MO - Receives Motorola IDs.

FM - Receives FM transmissions.

ED - Receives EDACS IDs.

CT - Receives CTCSS tones.

LT - Receives LTR IDs.

DC - Receives DPL (digital private line) tones.

Understanding CTCSS/DCS

Contents

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 (or more commonly referred to as tones).

CTCSS and DCS systems all use some form of coded squelch. Coded squelch techniques involve the transmission 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 same frequency 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 programming the CTCSS tone for a local channel the scanner will not stop on transmissions from the distant system. With few exceptions, such as the VHF Aircraft and Marine bands, almost every other VHF or UHF radio system uses some form of coded squelch. By far, CTCSS is the most popular mode among non-trunked systems.

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

DCS codes are similar to CTCSS 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 used.

Usually, but not always, VHF channels will use CTCSS and UHF channels will use DCS. If you operate the bank in open mode, the scanner will display the tone if one is received. See Programming Tone Codes.

The 'Scanning Reference' site has a very good page explaining CTCSS and DCS here.

Open and Closed Modes

Each channel bank can be set to open or closed mode.

In open mode the scanner will receive:

(1) all channels in AM, FM, CT, and DC modes, that are not locked out.
(2) all IDs in MO, ED and LTR modes, even if they are locked out in the ID list.

In closed mode the scanner will receive:

(1) all channels in AM, FM, CT, and DC modes, that are not locked out.
(2) only IDs in MO, ED, and LTR modes that are programmed into the ID list, and not locked out in the list.

In other words,

If you want to hear all IDs, scan in open mode. If you want to hear specific IDs, program them into the scan lists and scan in closed mode. If you want to hear specific IDs and not hear other IDs, program them into the scan lists, lock out the ones you don't want to hear, then scan in closed mode.

Searching for Frequencies

Contents

With a service bank search, You can search for CB, Marine, Police/Fire, Aircraft, or Ham transmissions without knowing the specific frequencies used in your area. The scanner is pre-programmed with most of the frequencies allocated to these services.

Or, you can program the Limit search to search within any lower and upper frequency.

Or, you can search up or down from a specific frequency using the Tune feature.

Marine, CB, or FRS/GRMS/MURS Search

Contents

The CB, Marine, and FRS/GMRS/MURS bands are actually frequencies pre-programmed into special channels. You are not searching from a lower frequency to a higher frequency.

To start a Marine(SR0), CB(SR1), or FRS(SR2) search, press search until SR0 (for Marine) or SR1 (for CB) or SR2 (for FRS) appears in the top left of the display. Press FUNC then SRCH to start searching. The channel numbers and search band name will appear in the display. Pressing FUNC and SRCH again will stop the search.

Note: if you exit the CB(SR1) or FRS(SR2) search without stopping the search, the scanner will start searching automatically the next time you return to the band until you press FUNC then SRCH while in the band to stop searching. You must press FUNC then SRCH each time you enter the SR0 (Marine) to start searching.

To change search directions or continue searching, press the

button. An arrow in the upper left of the display shows the direction.

To turn the Seek function on or off, press FUNC then 7 while searching. Seek ON or OFF will briefly appear on the bottom line. A highlighted S will appear in the right of the display when the 'Seek' feature is on.

To Pause on a channel, quickly press PSE to stop searching. **PAUSED** appears in the display. To resume searching, press PSE again.

To Step through the channels one at a time, press PSE to stop searching then press the

button to step through the channels. You can also directly enter the channel number (01-40). To resume searching, press PSE again.
Or, to see the channel numbers, press FUNC then SRCH to stop the search. Press the

button to step through the channels. Again, you can directly enter the channel number (01-40). To resume searching, press FUNC then SRCH again.
