Yesterday morning, I had some pretty horrendous line noise, which the 
KNB2 completely eliminated... then, in the afternoon I had what 
appeared to be the same noise (at least it SOUNDED the same to my 
ears), but the KNB2 couldn't do much at all. Same band, same RX 
settings, same antenna (and pointed in the same direction), same 
apparent direction of the noise, but something(!) had changed, to the 
point that the NB couldn't blank it adequately.

Of course, the NB in my TS-950SD couldn't/didn't touch it either!

But I agree that the KNB2, when it 'sees' an appropriate noise type, 
is WONDERFUL.
