Ok, I started it last night, will be only for one day, as I need my Rx for
other things as well.

No I don't mean the notch function. It's the fft-plug-in that you can create.
There you can modify the painting-routine itself. For example set black a
number of specific lines, so you can just remove the annoying lines within a
range but leave Alpha etc. unmodified. You can't achieve that with filtering
