This looks almost exactly like the noise I get from the wood products manufacturer next door. They use VFD drives on several motors there. One is 100 horsepower.
I get the interference also in the 75 to 80 meter band. The noise is also very bad just driving by their plant with an AM radio at 1700 kHz.
I am getting my ducks in a row getting ready to approach them.

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.).
