Hello folks, I am new to the site and am only a CB hobbyist. I have a older style cobra 25 LTD with the side mic jack.
It powers up, but there is only a very faint sound of static coming out of the speaker. When you key the mic the channel display goes out and there is no output on the S-meter or on the external meter. Have tried 3 microphones, checked the wires on the board on the mic jack and on the solder side of the board. Have also checked the voltage on the audio chip, I have 14.28 volts on the first leg and 13.75 on the last leg. I also have 14.28 volts on one leg of the final (2075).
I am stumped on this so any help would be greatly appreciated.
