Question about Radio Shack Pro-2096 Base Scanner

2 Answers

Squelch is open all the time

When powering up the scanner, the squelch is open all the time. On digital channels, you hear a steady "burst" of squelch as the scanner is scanning. On a conventional channel, squelch is open all the time and the squelch adjusment has no effect. There are times when this problem goes away, but not for long. It always returns. VERY annoying. I have uipgraded firmware to 1.4 and tried resetting, re-initializing and re-programming again and again with no luck. Anyone seen this before? Thanks

Re: Squelch is open all the time

Often the potentometer (squelch control) becomes worn or dirty, this can be sometimes cured by spraying a WD40 or similar oil and then rapidly moving the control down and up. Do not use oil that is conductive.

Re: Squelch is open all the time

I had the same problem on a pro-2096. Luckily I work at RadioShack, so I was able to send it out for repair for free. Our repair center replaced the PCB, and it works fine now.

I can't turn off the squelch on my Radio Shack Digital Trunking scanner.

On all channels, or on one channel ? Some channels are "birdie" channels, check your user manual. Others are problem channels receiving false signals from computers, monitors, receivers, internet equipment, FAX machines, etc. If your in conventional mode, if in Digital mode the squelch is set by the processor, and I don't believe the squelch has any effect in that mode.

How can i stop the squelch ive tryed turning the sqcuelch doesnt help

Plug the AC adapter into the back of the scanner and into a wall electrical outlet. Screw the antenna into the receptacle on the back of the scanner (extend the antenna to full length for best reception).

  • 2 Set the squelch level to allow signals to be heard by turning the squelch knob counterclockwise. Rotate the volume knob clockwise until you hear static. Slowly turn the squelch knob clockwise until the static noise disappears.
  • 3 Start programming frequencies into the scanner by pressing the "Manual" button.
  • 4 Press the up arrow or down arrow key until the channel you wish to program is visible on the display.
  • 5 Use the numbers on the keypad to enter the frequency for the local transmitter you wish to receive.
  • 6 Press the "E" key to complete the process of entering the frequency.
  • 7 Repeat steps 3 through 6 for each additional frequency you wish to monitor.
  • 8 Press the "Scan" key to start the scanning process. The scanner stops on a channel when it detects a signal strong enough to hear over the squelch setting. Two seconds after the signal stops, the scanning process resumes.

    Scanner acts like it doent have squelch control

    If your scanner is open squelched on one channel, try blocking that channel out. Some times a channel can get jammed if someone has a mic cue button stuck or something similar.
    Try locking out that particular channel and see if you get your squelch control back.

    Trying to program it

    First you'll need a list of frequencies to program. For a comprehensive database of active frequencies in your area, visit:

    Once you have your freq list, power the scanner ON,and:

    1. Press PGM. Then enter the channel number (1-200) where you want to store a frequency, then press PGM again.
    2. Use the keys to enter the frequency (including the decimal point) you want to store.
    3. Press ENT to store the frequency into the channel. Press DELAY if you want the scanner to pause 2 seconds on this channel before it proceeds to the next channel after a transmission ends.
    4. To program the next channel in sequence, press PGM and
    repeat Steps 2 and 3.

    • To listen to a weak or distant station, turn SQUELCH counterclockwise. If reception is poor, turn SQUELCH clockwise to cut out weak transmissions.
    • If SQUELCH is adjusted so you always hear a hissing sound, the scanner will not scan or search properly.

    I don't have the manual for my Uniden Bearcat BC 855 scanner.

    You can download/print the complete manual for your scanner by following the link below. It's a free download, and it provides detailed programming instructions. If you're programming a channel that is "empty" (showing 000.0000) just enter your frequency. Empty channels automatically show LOCKOUT but it clears with programming. The squelch setting will vary according to the strength of the signals you receive. Once you start scanning, turn the squelch down until scanning stops and you hear a hissing sound, then turn the control up slowly until scanning resumes.

    If the weather band is working, the scanner should be working. To verify operation:

    - Move the MODE switch to "Scanner" and power the unit ON.
    - Press the SVC button (chrome button below display).
    - Press POL (chrome button below display).
    - Turn the SQUELCH knob towards the left until scanning stops and you hear a hissing noise.
    - Turn the SQUELCH knob towards the right slowly until scanning resumes.

    If the scanner stops on anything - even noise, it's working.

    To Program:

    - Slide the MODE key to "Scanner."
    - Power the unit ON
    - Turn the SQUELCH knob to the left until you hear a hissing noise, then turn it the right - slowly - until scanning resumes.
    - Press HOLD.
    - Press E (PGM).
    - Press 0, 1.
    - Press HOLD.
    - Enter your first frequency, including the decimal point (EX: 156.055).
    - Press the E (PGM) key.
    - Press the UP arrow (above the SCAN key). Scanner will move to channel 02.
    - Enter your second frequency, including the decimal point.
    - Press the E (PGM) key.

    You should now have two frequencies programmed. Press the SCAN key . . .

    If it still will not accept programming, let me know.

    My Pro 96 does not come out of Squelch mode on any channels

    Are you hearing any communications at all? Sounds to me like someone has programmed the ctcss tones for each frequency. Try programming a frequency without a tone and you should get a squelch. If not then you probably have to return to the repair shop. GOOD LUCK.

    Scanner wont scan

    provided you turned the squelch know and it didnt help, i would trace back from the squelch control to the first and second transistor you come to and that should be the squelch circuit. if you know how to check them with an ohm meter you can find out which one it is, if not you can just replace them both for under 5 bucks.
