Hi Martin,
When trying to diagnose things like this, it's always a good idea to use
the widest possible frequency span, show a long waterfall (let it
average for as long as practical, make the waterfall at least half of
the screen height) and set the scale and reference so that the noise
extends from the bottom of the amplitude display to the top. This gives
us more clues about what it might be.

Here appeared a strange broadband noise over whole 80m band. No
birdies, sounds like an extreme QRN. Screenshots from my Elecraft P3
are here:
Dec. 4 3503 kHz

today 3537 kHz

I will be grateful for any advice (possible source, how to locate etc.).
