It is not a set and forget control, or one that can be used easily by toggling on or off. For some, this may be a problem. I'm on 160m right now, and the difference with my local noise, etc., is a good S-Unit. That's huge.
It is with deep regret that my type of noise (actually severe distortion of a 270Khz digital ballast) is not attacked with WNB; but hope springs eternal.
Now if there were a way to capture the IQ information and send it to FRS to use against any future algorithm.
Formula for noise: Take a 270Khz square wave, modulate with 600Hz half sine, further modulated by 60Hz half sine. Result: HF wipeout.
