Squelch won't turn off, won't go into power save mode


Power-save mode means the radio is being turned on and off repeatedly, to save power. The radio turns on, & if it hears any signals (i.e., if squelch circuit determines a station is being received), it turns on the speaker; else it turns off again to save power. So, squelch and power-save modes work hand-in-hand, and your problem is squelch circuit is either set too low, or a station is being received by the receiver. Download/look at the owner's manual and adjust the squelch circuit for a higher setting, and it should go into power-save mode again.
Good luck.

My Ranger2950 has no sound??


Have a look here for info about the Ranger 2950. This is an Amateur 10 & 12 meter transceiver that enjoy some popularity due to its ability to be modified to work on the 27Mhz Citizens Band.

Make sure the Mode is set to something other than PA. A few of the first things that come to mind is the Volume, Squelch & RF Gain settings. The Volume is straight forward - choose a setting in the middle to begin. Next, set the squelch. Most radios have the squelch open when set fully counter-clockwise. As you move the squelch to this position, sound should be heard from the speaker if a signal is present. As long as there is an antenna connected, the radio should "hear" noise. If you do not hear anything, leave the Squelch fully CCW and try varying the RF Gain fully in one direction. If you still hear nothing, set the Squelch to the fully clock-wise position. Adjust the RF Gain to the opposite direction. At this point, you should have heard something - even if just static hash. If not, the volume control may be dirty. Disconnect power and rotate the volume control back and forth several times to dislodge any dirt on the volume wiper inside the radio, and try again.

Make sure that the Ext Spk jack does not have a plug inserted as it will defeat the internal speaker. Likewise, if using an external speaker, make sure it works.

Good luck!

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!

The scanner is a model PRO-2050. It will only do squelching sound on all the channels and will not bring in any messages. I completely emptied the scanner. Then I put channel..1-8 in. yStill hear...


Hello,

Once you hear the sqelching, than you want to turn it back just till it stops. Make sure you have your scanner antenna all the way up and adjust it, slowly down, till you scanner starts to pick up. Believe it or not, the antenna has alot to do with picking up signals. Plus, you need to have it by a window, to help pick up stronger signals.

Radio shack can make you a copy of all the codes for this scanner. I would contact them, about your problems.

Kind regards!

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.

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.

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

Recieving problems


turn the RF gain all the way up and leave it there. Also turn the squelch down until you hear white noise, then turn it up just until it goes away.

RF gain is how sensitive your receive is. The higher it is, the more range you have. There really is no need to turn it down ever, unless you are trying to not hear some one out in the distance. Normal operation, RF gain should be all the way up.

Now squelch is used to quiet non signal noise. Like white noise or interference noise, Or other radios with a really weak signal that you can't hear completely any way.

You just want it so it just quiets the fuzz noise. Depending on background interference and the amount of radio traffic, the may have to be adjusted to silence the noise you don't want to hear. When a strong audio signal is received, it will break the squelch, the higher the squelch is set, the stronger the signal needs to be to break it, otherwise it will silence it.

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.
