How do you get the RX icon to turn off? The unit just has a contant fuzzy buzz.


RX represents "receive" This indication will be present whenever the speaker is producing audio. The "buzz" you're talking about is probably static, and is technically audio from the speaker. To silence the "buzz" adjust the squelch just until the speaker falls silent. The RX indication should be off at this point.

It is important to note that the squelch is designed to keep the speaker silent until a signal is detected. You adjust the squelch based on the level of static at a particular time and at a particular location. The static level may change depending on those variables. If you adjust the squelch well beyond the point that the speaker is silenced, you may not be able to hear transmissions or calls to you unless the caller's transmitter is physically close to you. This is why the squelch should be adjusted only until the static is stopped and the speaker is silenced.

I hope this helps and good luck!

Bc72xlt-no audio/sound/ kids pressing buttons then no sound


The best I can tell you is try readjusting the volume and squelch again. Turn your volume up then adjust the squelch all the way one way and then all the way the other way. At one of the max settings you should get static noise. This should allow you to see if there is any noise coming out of the scanner.

If you get noise then recheck to see that the scanner is programmed correctly. If it has no frequencies or frequencies with no traffic on them, you will not hear them.

If there was no audio with the squelch then you may want to consider that there is a bigger problem. Page 53 in your manual describes how to reset your scanner. This might work as a last ditch effort. You will lose all of your current programming though.

Hope this helps

Model SX750CR will send OK, can not receive.


There's no mute feature on 2-ways.

Will the 2 units work with each other? If so, then it could be an issue with the squelch codes.

There's usually a push button on those units that will "open" the squelch momentarily and you should then hear squelch noise and maybe get a green light to tell you squelch is open. If you have that and don't hear the noise, it could be a bad speaker.

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

Motorola FV500 2 way radio can send/cant receive


Do you hear the Beeps on the speaker? Check for the QT and the code squelch are the same in both radios, try to set code squelch in "0". Make sure that the radio is not receiving or the other one is not transmiting, with two radios will see the same.

Well my friend I have same problem with some radio. Maybe you should try just to connect detector to audio amplifier and than make an squelch circuit in AF?
