SOURCE: Cobra 29LTD speaker inop....No audio at all.

There are some different things you could be facing like:
the speaker sound being cut-out by the mic switch, but my first guess is the switch in the external spkr. jack being faulty. Here is a schematic for you.

plug the external speaker into your PA jack and select the PA switch. If PA works then the audio chip is good. The cobra 29 must have a mic plugged in to get receive audio, You may have a broken wire at the mic connector.

My cobra 29 turns on but i have no sound i can hear it key up and the meter swings speakerand mike are good could it be the finels


Are you sure its not on PA mode? And if the meter swings forwards its not a finale. It could be a bad soldier or IC chip. If you don't have it on PA to see if your IC chip is good take an external speaker plug it into your PA jack in the back turn on the PA switch and then key up the radio.Does it squeal or make any kind of noise if yes the the chip is good if no then there's your problem.If it is good Then its could be just a simple bad soldier.
