    [h=2]CB/Truck problems[/h]
    Ok I have a weird problem and wondering if anyone had heard of this!!!!! I just bought a new 2013 T660 and put my Cobra 29 (that only peaks at 22watts) Whenever I key up my engine fan comes on, QualComm starts talking, and all my lights on my dash light up. I have changed all the antenna cables and set the antennas. Its not the radio because I have tried a factory cobra29 with the factory mic. I am at a loss and the dealership doesn't want to do anything about it. Any help​

    I would double check your antenna mounts. Make sure the plastic insulator (washer) is on the top side of the antenna bracket. If that washer is not in right spot your cb output gets sent to directly to cab ground when you key up. It'll do some funky stuff sending power down the ground.

    It sounds like you are getting RF into your system. i would try to bond the door and the mount and the cab all to the frame . I would also feed the radio direct from they batteries for the hot and ground both . You might have a ground loop going on .
