I am new to this site and not savvy in electronics. I have a Connex 4600 Turbo peaked and tuned by a shop in GA. I'm using a Wilson 5000 antenna. When I first installed the radio, it worked well. Lately, I've been getting bleed through on the FM speakers. When this happens, there is no transmit outside the truck. Changed the coax, checked and adjusted the SWR (1.6) and no success. This radio worked wide open when installed and I have the same power/ground set up. I did everything the CB shop told me to and they say there's a problem with my FM radio. I disagree. I'd like some suggestions on a good shop I can UPS the radio to for a test. Thanks in advance for your input.
