CB will transmit but no receive

Testing my buddy's CB I figured out that my CB will transmit but not receive. I checked the wiring, everything is good. When I turn my squelch all the way down I get no static either like I should...

Time for a new radio or any other ideas?

Check the wiring in the mic connector. 99% of cbs will not have any audio with out a mike connected. Does the signal strength meter move? like it's getting a signal, you just can't hear it??

Yeah, but if the mic was bad, I'd think it wouldn't transmit.. But I will mess it it more.. If anything I can pick up a new mic & return it if that's not it..

It may be a speaker problem. Does it have an external speaker jack? If it does, you could connect an external speaker and see if you get anything. The meter should be moving in the receive mode if it is just a speaker problem.

The mic could have a problem that keeps the radio from receiving, even if it is connected.

Ok, messed with the mic, I don't know if that's it or not, but I tested a whole buncha other stuff..


So when I key the mic, the meter goes full like it's transmitting, and I know it transmits as my buddy and I verified. However, I receive nothing, but only on CB. If I turn it off of CB to one of the 3 weather channels, I get the weather, through the internal CB speaker, so I don't think it's the speaker. But I'm going to pull apart the mic cables and such, to take a peak in it. It wouldn't surprise me if it's just like one cable causing the problems. And I recently put my CB in a Tuffy overhead vs a homemade one, so the mic cable was at a bad angle at times..

There might be an unsoldered lead in the mic conector.
Easy to check, only two screws. Simple to solder.

As I mentioned before, the WX channels receive is unrelated to the CB receiver, so technically the receive portion of your CB could be damaged.
If when you turn the squelch all down on receive you see no movement of the signal meter, you might have a dead receiver.

At any rate, from a 29, I'd upgrade to a 148 gtl or the like with sideband, as it will give you extended range in sideband.

Yeah, I did that, just now actually.. no dice.. I checked the connectors inside the mic, doesn't appear to work.. So I'll probably look at some CB's tomorrow and see what I want there. Oh well.

XabuJr..... Can I interest you in looking at Ham Radio?
It is not difficult to learn and pass the required exams to get started in VHF/UHF and a bit of HF, and go from there.
You will find great info and help from fellow hams, keep a CB in the heep for trail use, and become a member of one of the greatest hobbies that is Amateur radio...!
It is easier than ever now that there is no code requirement.
And you can get your own personalized vanity license plate with your call sign for your Heep.
Give it a thought...

Yeah, I'm not against looking into it.. As I know the importance of keeping that hobby alive, especially more so in the case of emergencies and everything. I know there is the FCC test, etc, so it's something that isn't the easiest to just "jump" into, it takes some time, but something I probably should look into more.

I was just thinking that $$ that could go into a new CB could better go into a VHF radio and have greater fun.. I'd just ebay for a used CB to keep for trail and highway use.
I have a collection of CB's and mobil VHF's, and seems I've never driven a car of mine without at least one transceiver in it.
Let me know if I can help in any other way when you decide to take a look at the Ham stuff.

And more money to spend on another hobby

It's not that life is so short, it's that you're dead for so long.

Son of a .............

Got a new CB from a buddy for free. So after all my troubleshooting I decide to go with that to save time, then I can check out the radio when it's out. Pull the cable out.... it snapped off about 1/8-1/4" of the end of the coax inside the radio. That is what I'm guessing is the problem. So I'm going to dig that end out of my CB, then get a new cable.

Any ideas on how that could have happened?????
