Your Kenwood radio has programmable squelch. It is accessible through the software. However, if the squelch knob (pot) has been broken, it must be fixed or replaced. Move the control knobs back and forth, do either move more than say 1/16 of an inch? If so, they likely broke inside. You could open the radio, resolder the switch, which I called a pot and see if that works. If not, take it to a dealer or sadly, buy another radio.

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.

The cheapest solution would be to directly program the frequencies that are available in your area, usually this is public information with the exception of high security channels, you can call each location and ask them what frequency they broadcast

Yaesu ft-857 squelch problem


Your RF gain control needs to be turned all the way up to be able to receive signals and if you are on one of the HF bands like 40 meters or any HF band the squelch control needs to be all the way off! You do not use squelch on HF! When on VHF or UHF then you would rotate the squelch control just to the point that the background noise stops and go no further. Higher squelch settings will only block weak signals and your radio will be deaf! Squelch control rotated just to the point the background noise stops! NO SQUELCH ON HF. Turn the squelch all the way off on HF!

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.

Constant RX mode on Cobra Microtalk Walke Talke


I have the same walkie talkies and on mine I can hold down the mode/lock button and it will come off of the Rx mode. Also, you should be able to press the talk button and it will come off of the Rx mode.

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!

Check the squelch on your radio thats not recieving. If there is a monitor button ( when pushed you will hear static) try pushing it.. then get someone to call you so you can check if you can hear them. On these radios you have 2 types of squelch....1 is called carrier squelch.... it basically opens when there is a strong enough signal. This lets you only hear strong signals and "squelch out" the distant ones and background static. The2nd. is "tone squelch" ... with your radio they are often called privacy tones. If you have 2 radios set with the same privacy tones you will only be able to hear each other... only radios that are transmitting with that privacy tone will be heard on your radio. Its a high frequency tone that can't be hear by the human ear that gets "embeded" with the transmitting signal. The recieving radio hears it and opens the squelch. So... if the radio thats rxing (recieving)your signal has its squelch set for just carrier squelch it will hear any signal thats strong enough to break the squech open.... basicaly any radio within a certain range. But if your radio (one with problem) has its squelch set for privacy tones you will not hear any other radios except the ones set with the same privacy tone.... the squelch will not open until it gets a tx signal with the right tone.... so if the txing (transmitting) radio is not using tone squelch but is using carrier squelch.... and the rxing radio is set for tone squelch... the rxing radio will not hear it. With tone (privacy tones/codes) squelch you need a tone to open the squelch and then the audio can be heard... with carrier squelch the squelch will open if ANY radio is within a certain range. Check the squelch setting on the problem radio... it could have a privacy tone set. Try pushing in the monitor button so you can hear static ( you want to hear everything including static) on both radios... tx on one radio at a time and listen if it can be heard on the other with the monitor button pushed. If you can't hear any audio when the broken one is transmitting then it COULD be the mic.... if you can hear both radios with the monitor button activated than the radios are txing and have tx audio and are working... if thats the case its the privacy tones that are the problem. Take care
