SunSDR2 DX DSP (Digital Signal Processing) demo.

Quite often, but not all the time, I suffer from strong local QRM (man-made interference) which I am yet to track down. Last night it was very quiet, but tonight on 20m I have an S7 noise floor.
In this video, you hear the white noise and a sort-of buzzing at S7, then I engage the Noise Blanker, followed by the Automatic Noise Cancelation and I turn then on and off a few times. I think it's simply superb.

Man you have some horrid noise there for sure

Yes, it comes and goes but it's there more often than not however I have tracked it down to powerline noise. I hope to pinpoint which pole is the offender, this coming weekend.
