    I have a Cobra Nightwatch CB and it is picking up electrical signals from my tach, or my rotor. Its a high zippy noise that gets faster and louder the more gas I give my engine. Can this be solved? It's irritating. thanks

    You can get a filter from Radio Shack that should do it.

    It's your ignition system. Get a filter, it should help.

    Get the biggest one that they have when you get it. You might also try moving your cb's power wires.

    Is it best to put the filter closest to the battery connection, or closest to the CB (or doesn't it matter where inline it goes)?

    Put it as close to the cb as possible. You want the least amount of wire open between it and whatever you are needing to filter.
