Cobra 29 ltd classic year 2004. rf gain problems.

Replaced rf gain pot with new one still wont adjust runs wide open with hash and static in speakers to the point where receive is almost impossible to make out.transmit fine.have replaced several caps and diodes but no luck finding this problem....its not the antenna or mic try that already.

    I was about to give up on this and decided to pull the pot back out. that when i found the problem.it was something on my part, it was making ground off the pot that was beside it tight squeeze.working great now...checked the other pot that i had pulled out to start with, it was bad.

Put SWR meter between your antenna and output, test wave length receive/transmit, might need a ground plane or center loaded stick.
Could be transceiver relay, try clicking mic fast, it should click out as fast as you key the mic.

I have a Cobra ltd 25 classic in my pick up. the cb will turn on but i cant get any stacik no matter where i turn the squelch or rf gain. this doesnt seem right because it has never done that before. but...

Does the signal meter show any signal? Try plugging something into and out of the EXT Speaker jack to see if maybe that is preventing the internal speaker from working, or plug in an external speaker or headphone to test it. If the meter shows nothing, I'm concerned about your electronics, especially with the 'squelch' control 'wide-open'. 73's

Have Cobra 29 LTD Classic, no sound when hooked to antenna, no light or meter movement on the RF/SWR meter, DOES have power to radio and channel display, any tips to repair, or check for problem areas?

check the squelch by turning all the way both ways. check the external speaker socket. if it is the swicthing type it could be either bad conntact or dry joints. try an external speaker to see if that works. another thing is I believe it wont work if the microphone is not pluged in or connection fault there. Good luck.

Cobra 29 ltd classic

make shure that the rf gain on the front of the radio is turned up. if you have another mike that you can use on the radio.If the mike has a wire that has broke at the mike connector the speaker will not turn on when you unkey the radio.

Cobra classic 29 ltd

Had fixed the same problem yesterday. My cobra worked when it wanted to, when it didn't it looked like you explained. I found out that on my cobra the blue wire on the mike connector was broken. When it disconnects, no sound. after soldering, everything works fine.
