At Rigi we have a electric fence from the farmer. The NB button does not help.
It would be great to have a NB, which let des fence click (audio) disappear.
Flexradio is using a special technology, where you can delete even the horizontal lines from the electric fence in the waterfall.

I had websdr.org software and the fence-clicks where impossible to remove.
It's not as simple as you think.
But the NR does a great job of lifting the signal above disturbance, for me it works great on 80m.
The problem is, how do you know all horizontal samples are clicks and what are not?
I mean, on a single band 100KHz wide like most radio's do it's not that hard, but on 30MHz? How do you mark them being clicks and what not?
My Kenwood TS-890 is incredible for this, but it's also doing 500KHz waterfall but only 5KHz audio-sampling.
As with the wideband websdr audio and waterfall are processed seperatly, waterfall = serverside / audio = clientside...how do you signal this that something is a click?
Like my Kenwood your Flex is processing everything either server or client, but not seperated.
In my humble opinion that is where the problem of NB is.

I agree, NB is very complex. And NR works really great :-) I really like it to use NR on 80m and 40m.
