I figured it was switcher, but I have never seen one move in frequency
so far so fast. Anyway, when I get around to finding it, I'll report back.

That is likely a harmonic of a switching supply that is relatively
unregulated, as the line voltage changes the frequency of the switching
changes. I can't tell the frequency range you are monitoring, but in
general switchers like that are probably around 50-100khz with harmonics way
up the bands. The lower in frequency you can find it the less it will shift
and the narrower the noise will be.

Hi all,
This one is going to be difficult to find with a conventional receiver.
Guess I am going to have to activate my SDRPlay from the car.
