CB Transmitting & Receiving

Question for you guys. I just hooked up my CB. I can transmit just fine, but I can't seem to receive anything. It is either squeeling at me or it just makes noise. What am I doing wrong or what could be the problem?
TIA.

I'm in the exact same boat. I hooked up my CB yesterday after I installed a new amp. I know I'm transmitting because of the interference with the new speakers

Did you check your SWR's. Read this if you have not. Do not use the CB till this is done..

Good advice. Also make sure the squelch is adjucted properly.

Yes, I checked my SWR and it was around 1.5. I figured that would be fine for the day trip I was going on. I need to mess with the squelch a little more. I was playing with it and it did not get any better. Could it be the coax or my ground? I have it grounded with my KC daylighters. I receive the weather channel ok. If I turn that up too loud I get some interference.
Any other ideas?

Thanks

OK, I messed with it more and I can get it to transmit to mine but along with the sound of my voice, I get a lot of noise. I've adjusted everything but it won't stop. Could it be something else? Could it be my radio?
Please help.
Thanks.

How's the noise problem going ?

Do you have the noise with the engine running or not ?

A poor/high SWR won't affect how well it receives. Does your new CB have an RF Gain control and if it does, is it turned up all the way? Is your squelch turned up too far? Does the noise problem also happen when the engine is off?

I have only been testing it with the engine off.
I have adjusted the RF from top to bottom along with my squelch.


Thanks guys.

Turn the RF Gain all the way up and leave it there. Adjust the squelch so the loud hissing noise just shuts off. You say it transmits ok, does that mean that someone who is a good distance away and not right next to your Jeep receives your transmitted signal just fine? Your microphone is plugged properly and securely? While the microphone wouldn't normally be thought of as being able to screw up the received audio, it can because the audio of some CB transceivers passes through the microphone wiring.

OK, I thought I have tried that, but maybe not. I will try it again. I am actually testing it with a CB that is close. So I need to be farther way to make sure it works correctly? Maybe that will get rid of the squeeling? The sound is like when 2 people with microphones get too close together, but it only happens with I key up the other one, not mine.
Thanks Jerry.

Oh ok, based on that it definitely sounds like the other transmitter is overloading your CB by being too close when it transmits.

Actually, after playing with it more last night, it turns out its his mic that is making all the noise. So its his fault
But now I seem to have a problem with my volume. I have to have it turned all the way up to barely hear anything. It was loud before. Did I get a piece of junk or do you think there is something that can be remedied?
Thanks for all your help Jerry.
