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.

    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.

    Model BC248CLT. Unit locks on each channel with static noise as if squelch was misadjusted. Manual channel change and adjusting squelch does not eliminate the problem. Thanks

    Not sure about your particular model but many modern scanners have a "wait" function that can be used during a scan. Actual details vary from model and manufacturer.

    I do believe you are seeing that behavior. Quite often this can happen regardless os a manual squelch setting.

    If for instance it was set to scan for a low signal level AND (pause or stop) at that channel then no matter what you turn the squelch to it will do what it was told from another menu.

    You should check the advanced scanning section of your manual for any similar functions.

    If you are using software to run the scanner this too may have a similar setting so check there too.

    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.
