[Elecraft] Noise Blanker Problems

[Guy Olinger K2AV]

The mechanisms of noise reduction nearly all result in artifacts of
some sort, which a given individual would describe as distortion

Removing anything "unpleasant" from the RF off the antenna while
surfacing a perfectly formed SSB audio which was formerly buried in
the unpleasantness and totally unintelligible, or even so weak it was
not noticed, is the holy grail of noise reduction.

I've set right beside someone who called a signal "distorted" and I
could not hear it.  It's all in the ear of the beholder.

Some recordings of the audio posted to a web page and linked from an
email here would be useful.

73, Guy.
