Is this power line noise?

I see this everyday now in our new location at this campground. I haven't seen it before.

Is your, or a neighbor's wash machine running? Looks similar to PWM driver interference.0
-
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?1
-
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 had a switching inverter on my camping trailer that look very much like that.0

(pun intended).

Might be Solar Panels???0

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.1

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 !0

I gue As I am not literate but what is a wall watt?? I have strange signals on my radio.0
-
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.0

remember the good ol days when they did their jobs?0
