You may have a bad transistor or detector diode that feeds the squelch circuit.If you can read a volt meter and Ohm Meter, and can solder ( Make your own repairs ) you may want to call Galaxy as the Techs there are normally very helpful.
Good Luck

SOURCE: Cobra PR4750WX - how do I adjust squelch?

You are right there is no adjustment. You can however turn the squelch off and this maybe what is happening to you.
To turn the squelch off you press and hold the button that is just below the push-to-talk button for at least 5 seconds.
To turn the squelch back on, you either press (less than 5 sec.) and the same button or change channels.
When talking with a specific party or group, you should use the tone coded squelch (CTCSS) and that will mitigate the noise if you are not already doing that.

SOURCE: transmitting and receiving

RF gain should be all the way up. Turn the squelch all the way down. Turn the ANL/NB to just ANL.

Turn the dynamic up at least 3/4.

Once you have confirm you can receive and transmit, then you can turn up the squelch up until white noise just stops.

Make sure you are on 19 by the highway. Key up and say break break one nine, can some one give me a radio check please.

you should get a response.

Your RF gain is how much you receive. the higher it is the more you receive. In normal operation there is no need for it ever to be less the all the way on.

Squelch is just to knock out fuzz, and if you only want to hear people close not far. A little less then half way is a basic setting.

the ANL switch is the automatic noise limiter. if you have interference from your vehicle, like engine noise, turning this on will quiet that. If it is extreme engine noise then switch it to NB, noise blanker. It is just a more intense setting.

your dynamic is how loud your audio is. if its low or all the way down, you will not transmit audio loud enough for people to hear. If its a stock radio and has not been tuned, if you turn it all the way up, that is fine.

SOURCE: president Harry 2 classic does not listen (receive)

Hi and welcome to FixYa,

Initial tests:

  • if there is likewise no TX modulation, check / replace audio IC4 TDA1905;
  • if RX signal strength (S meter reading) is low, check RX + 8VDC;
  • try using an external speaker in case of a faulty internal speaker;
  • exercise the AM/FM switch.
If all of the above checks good, then signal tracing from the front end down to the audio amp. Would the schematics help?

Good luck and thank you for asking FixYa.

How do i adjust the squelch?


Turn the squelch control clockwise just enough to cut the background noise, this should work well for local communication.

My blackbox radio breaks squelch only when button is pushed.


I am familiar with radio programming software , but not your model. You could have squelch adjustments or settings that need to be set in the software end. Did you set something to mute? Can you set the signal level for the radio to open squelch? Are you able to connect to a service monitor and inject a signal and see where it does break squelch? These are things I would check.

You are describing an open squelch. If this unit has a squelch control, adjust it until it quietens.
If the battery voltage drops below a certain point, it won't squelch. That could be caused by a battery that needs to be charged or a bad battery that won't charge up correctly.

Squelch doesnt work


Open the component / speaker side cover on the radio, adjust VR3, this is the alignment control for the squelch. Set your squelch control knob on the front of the radio to about 10 o'clock and slowly adjust VR3 until the signal from the speaker is mute.

When you turn the squelch back to the 0 position, you should have signal with no squelch as in normal operation.

Thanks!

How to set squelch on a motorola t73xta7ta7bk 2 way radio


That is a Maratrac, the squelch is adjustable thru a variable resistor on the audio/squelch board within the chassis. It is labeled R1132 SQUELCH, and is located very close to the locking handle. Some models have a metal bracket that holds the interface board, (thats the only board in the chassis that is mounted vertically), if you remove this bracket you can see R1132 alot easier, but do not need to remove the bracket to adjust R1132. Clockwise tightens the squelch. One catch though, for this adjustment to work, the radio must have been programmed with the unmuting/muting setting in the RSS, set to And/Or. It comes from the factory set for Std/Std. And in my 15+ years in the business, I have seen only one programmer that changes this setting. Me. Good Luck.

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
