As many of you know, I had a J&M CB2003-DU installed alst week, and was fortunate enough to have a friend adjust the antenna for me. It worked fine until tonight, when for no reason at all, it became stuck in transmit mode, as though one of the PTT buttons was pressed. Upon switching it on, it bleeps as it always does and then plays the radio or CD for an instant, before beginning to transmit. It will not respond to pressing the PTT buttons, nor any of the buttons on the unit itself. It's stuck on channel 5, the last channel I used. I looked at the wiring that was visible, but nothing seems disconnected or out of place. The only thing I noticed was that when turning the bars full right (pulling the throttle side toward me) it squeaks like two pieces of rubber going past each other. No cables seem to be overly taught, but that's the only anomaly I see. Any ideas, oh wise ones?
