    Yes , squelch was on when using a HT. Doesn't make a difference if "woke up" or not . Noise stays constant as long as radio is on. I havent tried an external battery to power radio yet. That was my next try when I get a day off. Thanks for all the input guys.

    Could you be receiving noise from your house or overhead power lines? Might want to find an empty parking lot to check.

    Noise is everywhere. It doesn't matter where I drive to. Even if I am sitting in a field with the engine off. S7 noise level. I have tried 4 different radios and they all have same noise on 2m.

    Phone charger plugged into the cigarette lighter?

    Different radios... Same antenna/coax? Does it do it with the coax disconnected?

    No cell phone chargers connected. Yes, it does it even with coax unhooked. Here in the Twilight, here in the Twilight Zone.

    Try pulling fuses one at a time until you find the culprit.

    I do not know the truck well, but pulling from other suggestions, could there be a cig power outlet in the back area, hidden that might have a cell charger in it?
    Check the manual to see if there was a 120VAC inverter option?
    Just grasping for straws here.
