Being in a semi-rural environment, I find that I don't have too many
times when the KNB2 is needed.  When the occasion does occur, it seems
to no less effective than the noise blanker on my TS-570D.  

Although it is designed for a different noise characteristic, I find
that the noise reduction of the KDSP2 is much more effective than that
of the TS-570D.
