    Is your, or a neighbor's wash machine running?  Looks similar to PWM driver interference.

    No.....we are in a more than half empty campground. Nothing at all running in our camper. This same camper at different locations, does not show this. That's why I suspect it has something to do with the location.
    A power transformer is about 900 feet away from us.

    I should add that this is only between 8Mhz and 5.2 Mhz

    I have a wall wart that makes noise which looks just like that, although a bit fainter. Squirms around a bit and slowly migrates in frequency. Do you have neighboring campers?

    No neighbors yet. The weather here is still pretty cool and wet.
    BUT....I think you're on to something.....there is a wall wart in the radio cabinet I will move to test. I wish I would have thought of that.

    Thank You !!!

    I have a bunch of old AC to DC wall wart's. When I find a new one that makes noise I trade it out. Be nice of the FCC enforced it's own rules.

    I have some monitors that radiate something similar. I think its the cheap design of the power supplies, thank you FCC in allowing the cheap Chinese junk to be imported ! I would gladly pay a few pennies more for something that doesn't spew out and radiate garbage !

    You know - those little solid state power supplies that plug into the wall to power your 12V or 5V devices - like the charger for your phone, or the AC power supply for your laptop.  Those are wall warts because that's what they resemble.
