SOURCE: scanner static

Use the channel lock out control, unless it is a frequency that you listen to, you may have interference that is causing random static. use a noise filter mechanism to minimize this problem, or buy a specialized scanner antenna that's guaranteed to minimize static.
If no avail, you may need to send it in to a store.

Hope this helps!

SOURCE: 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.

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.

Uniden Bearcat BCD996T will not squelch, just has constant noise on every channel. Any ideas on what has happened


Have you done a reset just to make sure something such as static did not change the software in the microprocessor? Try that before you go to a repair shop.

Constant static on my walkie talkie


Check the squelch level, either the knob or on the menu. When the squelch is 'open', there will be constant noise. If someone is transmitting nearby, do you hear them clearly? If not there may be a problem with the receiver in the radio.

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 have a galaxy 33hml and i can not figure out how to set it up with the nobs i mean can you help me....


    first of all is it set up to a antenna source? if so then turn the squelch nob counter clockwise all the way, then turn the device on. next start at channel one and slowly turn the squelch clockwise until the pin moves or you hear static. then surf the channels adjusting the squelch to to that static point until you find your active station. from there to cancel static between transmissions turn the squelch so that it is just below the static marker.

    My Binatone Marina 300 Walkie talkies give hiss & noise. Pressing menue and up or menu alone makes no difference. How can I have a quiet radio except when called?


    Hello andy300,

    Does the "RX" indicator show on the LCD screen constantly?

    This radio does have a monitor function which disables the squelch control, allowing the user to listen to weak signals on the channel. Enabling this function in absence of any signals will cause the user to hear any background static or noise on the channel. You enable this function by pressing Menu + Up at the same time and disable the function by pressing Menu.

    I assume that you are familiar with this function from the fact that you mention these keystrokes have no affect on the radio's behavior.

    It is possible that the area you are using the radios in / channel you are using them on has a very high noise level. If the noise level is higher then the radio's automatic squelch threshold, then you would hear constant static, hiss, or white noise and the receive ("RX") indicator would show a constant signal. A local noise level can be caused by atmospheric conditions or very busy nearby adjacent-channel radio signals.

    Try operating the radios on a different channel and see if that helps. If it is practical, you might try operating the radios in a different local area just to see if that has any effect at all. This would help you determine if the problem was a local one specific to the area you are operating in.

    If it is local area related you might consider switching to a different model of radio that includes a Continuous Coded Squelch System (CTCSS) function (called "privacy codes" or "quiet tones" by come manufacturers. This function does not appear to be included in the model you are using and can help keep your radios silent unless you receive a call from another radio using the exact same privacy code.

    If the problem persists regardless of channel or area, then you might have a problem with the radio that would require factory service.

    Hope this helps. Best regards!
    Ken
