I've been working a shit ton of hours over the last few months. About a month ago my cab quit working face wouldn't light up. Figured that was simple and a lack of power to the radio. Then it would start working coming on but wouldn't receive signal or transmit. No audio. I just bought a uniden pro520 today wondering if the old one was going gunny bag inside. That one has the same issues too. Powers up, but no audio. So replace the antenna is my next guess. The old existing one is either a firestik or firestik 2.
