    Try wiring in an engine noise filter, they're cheap I think...like 10 bucks or so. What type of cb is it?? I know some cobra's and midland's (Same thing, i know) Have a switch that helps cancel out some of the noise. Just what i know

    The noise is comming from your alternator. Any power source inside your cab will have it. What you can do is wire direct to your battery. Make sure to take the wire and basically follow your headlight wiring to the battery. You know, over the wheel housing and behind the grill. If you go by the firewall, you'll pick up distributor noise.

    try re routing the antenna cable, coax isnt perfect, it may not be in the power cable, but the antenna. there is, if i may say, an "antenna cable G-spot" in every vehicle, just have to find it.

    If the noise you are hearing is a whistling noise a noise supression filter may help. If it kind of like a static noise it could be just the way it is right now due to atmospheric conditions. If you set your SWR's and have the antenna and radio grounded good and you are still picking up a lot of noise that you can't squelch out then chances are it is the conditions. It may sound like a pain but if you are hearing this noise during the day go out about 3 AM and turn it on and see if it is still there. I bet it is much quieter.
    Also, what length is your coax and what kind is it? (ie:RG-58, RG-59, RG-58u, RG-58AU, etc) You need to have the coax at least 18 feet long. If it needs to be longer go in increments of 3 feet. That will keep the wave in check.
