this is gonna sound like a stupid question, but, do you have a headset plugged in?
did you turn the squelch all the way up?
clean the plugs, spray contact cleaner into the transmit switch. make sure the "cb" showes on the panel, and the little headset(on the panel) is off.
sounds really basic but we tend to overlook the simple things. i know firsthand.

if none of that works and your close to st louis, come on over we'll compare it to mine.
