On some 4 pins you can still hear the radio with microphone. Stick an external speaker in the Ext. Spkr jack hole, on the radio set, and see if you get sound. This would eliminate a speaker issue. Is the squelch all the way down ?, find someone elses mic and plug it in. If this fails, email the pregnant dog, so he can tell you "it was working when I sent it".
i will try that, and no the squelch is not all the way down. i have tried messing with it while the cb is on to see if that makes a difference.
