Question about Cobra 29 LTD CB Radio

3 Answers

Cobra 29 NW LTD does nothing

I was recently given this radio from a friend of mine. He bought the radio new about 2 months before. The radio worked fine. He took the radio to a local CB shop to get some extras added on. As far as I know he had talkback added, a meter that changes colors, and he had it tuned up. When he got it back it did nothing at all. So he gave it to me. Is there anything that I should check out.

Yes, take it back to the cb shop. If they are a reputable shop, they will stand behind their work.

I own a shop and have always stood behind my work 100%. Once I went so far as to buy a brand new Magnum S-3 to replace a used one for a customer that one was messed up doing a power modification that should not have been done on that radio. I came to find out that the company I bought the mod kit from didn't know what they were doing and had the instructions wrong. I still have the broken radio to prove it.

Why do you have to fix it? If the local CB shop looked at it last then take it back to them its their problem.

Low transmit audio cobra 29 ltd nw

Are you talking about this radio or what others are hearing from your radio?

My friend, no one but the holder of a 1st class FCC radio license is permitted to adjust the input power to the final amp. Further, one needs some pretty technical equipment to accomplish this fine tune adjustment. Failure to properly set this envelope will result in degraded operation and possible failure of your radio.

If you can't live with the present circumstance, get your radio profesionally repaired.

Thank you for your quesiton at

Cobra 29 LTD Classic not transmitting or receiving

As I understand from a tech friend of mine, most truck beds are not grounded well enough. Perhaps you could borrow/purchase a magnet mount antenna and locate it on the roof, for testing. Then you would have it narrowed down to the location.

Cobra 29 issues

Check D23 and D28. They are polarity protection diodes. It could also be the power knob.
