TRUNKTRACKING SCANNERS

General Questions

Product: General Information
Question: What is trunktracking and where can I get more information?
Answer: Trunktracking is the hobby of using a scanner to follow conversations on a trunking communications system. Trunking systems let a large group of 2-way radio users (or even different groups of 2-way radio users) efficiently use a large range 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 (on a different frequency called a data channel) 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. Trunking scanners let you select and monitor the data channel frequency sent with a 2-way radio transmission, so you can hear the call and response for that user and more easily "follow" the conversation.

Question: How do I convert EDACS SYSTEM ID format (decimal to AFS)?
Answer: Our scanners use either decimal format or decimal and AFS format. You can convert decimal EDACS IDs to the AFS (Agency-Fleet-Subfleet) format as follows:

The example below starts with the Decimal ID 0586.

  1. Convert Decimal to Binary
    586 decimal = 01001001010 binary
    ID's are 11-bit binary. If you get a binary that isn't 11 bits,
    just add leading zeroes until you get 11 bits.

  2. Split the binary as follows #### / #### / ###
    0100 / 1001 / 010
  3. Convert each GID to decimal
    04 09 2
  4. Format as ##-###
    04-092

Product: Troubleshooting
Question: I can't scan an EDACS system, and I know the frequencies are right.
Answer: With an EDACS system, the frequencies have to be in a particular order. Also, unless indicated otherwise in the scanner's manual, you should not mix other frequencies in the same bank as the EDACS frequencies. We do not have information on the correct order for specific EDACS frequencies.

Product: Troubleshooting
Question: Why does my scanner take so long to pick up data channels?
Answer: You are probably operating in a fringe area for the transmission. You would need to improve the signal strength, either by changing locations or using a larger antenna.

Product: PRO-70 50-Channel Scanner Cat. No.: 200-0310
Question: The scanner is locked and I cannot unlock it; what do I do?
Answer: You will need to do either reset or initialize the scanner. You should try to reset first; initialization clears all information in memory.

Resetting the Scanner

  1. Turn off the scanner, then turn it on again.
  2. Insert a pointed object, such as a straightened paper clip, into the reset opening on the side of the scanner and gently press then release the reset button inside the opening.
    Note: If the scanner still does not work properly, you might need to initialize the scanner.

Initializing the Scanner

Caution: This procedure clears all information you stored in the scanner's memory. Initialize the scanner only when you are sure the scanner is not working properly.

  1. Turn off the scanner, then turn it on again.
  2. Press and hold CLEAR.
  3. While holding down CLEAR, insert a pointed object, such as a straightened paper clip, into the reset opening on the side of the scanner and gently press then release the reset button inside the opening.
  4. When the display reappears, release CLEAR.
    Note: You must release RESET before releasing CLEAR, otherwise the memory might not clear.

Product: PRO-79 200 Channel Handheld Scanner Cat. No.: 200-0314
Question: Page 10 of the user's manual states that you must recharge high-capacity Ni-Cd batteries in an external charger and that "You cannot use a DC adapter to recharge batteries in the scanner due to limitations in the scanner's recharging circuit"... What exactly are these limitations and why can't I charge high-capacity Ni-Cd batteries?
Answer: We do not recommend that you use the DC adapter for charging because the DC from a vehicle tends to have voltage fluctuations and noise in the signal. When charging, these fluctuations and noise can cause the battery to not take a charge as well and lessens the battery's capacity and effective life span. The charging circuit is not designed to compensate for these problems, so it should only be used with an AC adapter. Standard life Ni-Cd's take 14 to 16 hours to recharge in the internal charger; this charger is not designed to charge for the extended period required for high capacity batteries. Using it in this way can damage the internal charger, the batteries or both.

Product: PRO-92 Multi-trunking Scanner Cat. No.: 200-0522
Question: What is the difference between the 200-0522, 200-0522A and 200-0522B versions of the PRO-92?
Answer: The primary differences are either in the firmware version and/or the trunked scanning method.
PRO-92 200-0522
Firmware: Version 1.0
Trunked Scanning: Low Speed Handshake
PRO-92 200-0522A
Firmware: Version 3.xx
Trunked Scanning: Control Channel

After introduction of the PRO-92, we learned of some instances where it didn't perform to expectations on some Motorola trunked systems. Based on this, a few customers have raised concerns about the quality of the PRO-92. An update to the software (changing the scanning method from "Low Speed Handshake" to "Control Channel") improves performance with these "troublesome" trunking systems. Effective immediately, we are offering this upgrade for the price of labor only. You would need to take the radio to your local RadioShack store and have them send it to the service center. Through cloning, reasonable efforts will be made to retain the programming in the scanner's memory.

Warning: Do not send a scanner that currently works fine on your local trunked systems just because it has version 1.00! If the scanner already works well in your area, this update is not needed.

The only significant difference between the 200-0522A and the 200-0522B is that the manufacturing location changed.

Product: PRO-92 Multi-trunking Scanner Cat. No.: 200-0522
Question: How do I assign a two-line text tag?
Answer: When programming a text tag, it only allows you to put one line in. To have two lines of text as tags, you must also assign a text tag to the bank.

For example, assign a text tag to the bank as "Arlington", then assign a text tag to an ID (or frequency) such as 'South Police'. When the scanner picks up that ID (or a transmission on the frequency) it will display both tags.

Product: PRO-92 Multi-trunking Scanner Cat. No.: 200-0522
Question: How do I get this scanner to simultaneously track both Motorola II & Conventional frequencies?
Answer: This procedure will only work on the PRO-92, since it tracks by the SID's, and not the data channel, and only in the open mode. In closed mode, the scanner will look for programmed SID's before it stops on a transmission. Here are the steps to set this up:

1. Enter all the frequencies (both conventional and Motorola II) in the same bank with the manual programming.

  1. For the Motorola II frequencies, press Mode to designate the RF as MOT then press /\ (up arrow) for the next channel to be programmed.
  2. For conventional frequencies, do not use the Mode button; press /\ (up arrow) to go to the next channel.

2. Once all of the frequencies are programmed in the Bank then:

  1. Press Man.
  2. Press Scan; the PRO-92 will start scanning and stop on the first data channel.
  3. Lock Out any/each data channel when the PRO-92 stops on it. After the data channels are locked out the PRO-92 will continue to scan and will show SIDs on the Motorola II channels. The Motorola II channels have a sub-audible tone that equates to the SID, and the PRO-92 will pick this up and display the SID even with the data channels locked out.

Product: PRO-92 Multi-trunking Scanner Cat. No.: 200-0522
Question: Between the PRO-92 and PRO-94, which has the better scanning scheme?
Answer: In our testing, we placed a PRO-94 side by side with a PRO-92 and found each radio missed a few (and only a few) hops. The missed hops were about the same - neither radio got everything. The significant difference was that if the PRO-94 model holds on a specific ID and misses a hop, the hop is completely missed, where the PRO-92 typically picks it back up after a second of delay. The reason for this is that the PRO-94 scheme looks only at the data channel; if it misses the data, that transmission is completely lost. In contrast, the PRO-92 reads the subaudible data on each transmission. If it misses the hop, it continues to check active channels and easily finds the conversation again.

While the schemes are different, we did not find that either design was significantly better than the other.

Question: Between the PRO-92 and PRO-94, which has the better scanning scheme?
Answer: In our testing, we placed a PRO-94 side by side with a PRO-92 and found each radio missed a few (and only a few) hops. The missed hops were about the same - neither radio got everything. The significant difference was that if the PRO-94 model holds on a specific ID and misses a hop, the hop is completely missed, where the PRO-92 typically picks it back up after a second of delay. The reason for this is that the PRO-94 scheme looks only at the data channel; if it misses the data, that transmission is completely lost. In contrast, the PRO-92 reads the subaudible data on each transmission. If it misses the hop, it continues to check active channels and easily finds the conversation again.

While the schemes are different, we did not find that either design was significantly better than the other.

Question: How do I turn off Hypersearch? I can't get HYPER off of the display.
Answer: Hypersearch can only be turned on and off through a limit or direct search. To turn it off, you should do the following:

Through Limit Search:

  1. Press PROG, then LIMIT (SRC). Lo and 29.000 MHz appear. 29.000 MHz is the low end of the scanner's range.
  2. Enter the frequency that is the lower limit of the range you want to search (including the decimal point), then press E (SVC).
  3. Press LIMIT (SRC). Hi and 1300.00 MHz appear. 1300.000 MHz is the upper limit of the scanner's range.
  4. Enter the frequency that is the upper limit of the range you want to search (including the decimal point), then press E (SVC) again.
  5. Press \/ to search from the upper to the lower limit or /\ to search from the lower to the upper limit.
  6. While the scanner is searching or is on a transmission, press H/S.
  7. HYPER should disappear from the display.

Through Direct Search:

  1. Press MAN.
  2. Enter the frequency you want to start from using the number keys. (Press . to enter a decimal point).
  3. NOTE: To start the search from a frequency already stored in one of your scanner's channels, press MAN or PROG. Then use the number keys to enter the channel number and then press MAN or PROG again. If you enter an invalid frequency, the scanner displays Error. Press MON/CLR (.).

  4. Press \/ to search downward or /\ to search upward from the selected frequency. -d-, SEARCH, and either \/ or /\ appear.
  5. While the scanner is searching or is on a transmission, press H/S.
  6. HYPER should disappear from the display.
