And here is another post about the NB.  It's not perfect, but the fact
that it actually has an effect and can kill noise is relevent.

I have to admit I finally heard a NB work today.  It was K3 #24's.
Frankly, I'm amazed.... and very pleased.  I had been trying to prove
that the K3's NB wouldn't be any better than the other dozen or so
I've had time to try out over the years.  Read on.

There is some bizarre OTH monopulse radar going on, quite audible on
60m channels. It registers around S8 here.  I can kill it with IF MED1
or MED2 and a light dusting of the DSP T2-7.  With the NB on these
settings, the band noise shows S5 or so.  Back to the normal
background noise.  Mainly city-dweller noise.  No pops.  Just sky
noise or local stuff.

I apologize for being A Doubter.  At least there is a freq and time
for all to see the same results:  0500Z or so would do it, at least on
the West Coast of the US.  I've observed the same basic stuff(tm) on
60m over a span of weeks of band-scanning.

Not bad Elecraft!  Rep rate is maybe 8-10 Hz or so, and there are two
sources.  One at the S8 level, and another about S9+15.  Both can be
made to disappear at will.  With the right noise blanker that is.
