When the engine is running i have to turn the squelch up high to keep from hearing noises from my truck ex. if my radio is on and i hit the botton to roll the window down you can hear it through the speaker on the cb

Crank your squelch fully counter clockwise and you should hear a lot of static. Start turning it clockwise until the noise stops. If you find the noise sometimes breaks through, then turn it a little bit more clockwise. This is just about optimum.

I think its vr6 in that radio but you have to turn it till you hear noise. did you use a signal generator to set the squelch?

The Squelch control is turned too far down. The control should be labeled "Squelch" or "SQL" Turn this control clockwise until the white noise stops. You may want to turn it very slightly further, but not too much.

This control sets the sensitivity of the radio, if too far counter clockwise it will receive noise. If too far the other way it will only receiver very strong signals.

Turn up your SQUELCH button when no one is talking until the static noise just goes away.

Now your set will remain quiet until someone talks.

If you set the squelch too high it will also cut out the people talking, so always try to have it set just slightly above the background static level.

Good luck.

I have the same radio as well. If you are running a "stock factory mic".....do this:
VOLUME: set to your comfort
SQUELCH:all the way to the left (if you don't mind hearing everything other wise adjust to the right to illiminate noise)
DYNAMIKE:If you have a factory mic or "noise canceling mic", turn all the way to the right (unless it squeals and then turn the mic gain down slowly until the squealing stops)
RF GAIN:that is your "receive" and I always turn it all the way to the right to maximize reception! In my opinion, this is the dumbest knob ever made since why not hear as good as you can??? thats what the SQUELCH is for!
DELTA TUNE: IT IS "USELESS!!!
SWR CALIBRATE: don't ever trust it! ALWAYS USE A GOOD SWR METER "IN LINE"
Now as for the "SWITCHES"
The top left switch is the SWR and as I stated, do NOT trust it and leave it on "S/RF (TOP)
SWITCH TWO: If you have it on OFF, you may get allot of engine spark plug firing noise so I run mine in the "middle" (ANL)
THIRD SWITCH: CB
FOURTH SWITCH: Brightness is to your liking!
There ya go! You can always set the switches to your liking and comfort.

Try this. While with the engine running and radio on, while you hear the noise, disconnect the antenna wire from the radio. (DO NOT KEY IT).

If the noise is gone, then the noise is coming in from the antenna. A new location may be needed.

If the noise is still there then its coming in from the power line. You need to get a ground loop isolator. Make sure its not one for RCA cables. You need one for the power line. It connects to your power source, and then your radio connects to it. this will take most of the noise out.

What you want to do is tighten up the squelch adjustment and that should reduce the white noise you are hearing. also keep them away from any computers, the square waves generated by them will open up your squelch annoyingly as well.

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.

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

when i turn on my radio it keeps beeping repeatly nothing else happens
