[Elecraft] K3 noise blanker

[Stephen Prior]

This is a 'me too'.

Having, in waiting for my K3, read all sorts of accolades for the NB and NR,
I feel, now that I have the radio in front of me, somewhat deflated.  The NB
is, it seems to me, no better than many others I have used (eg TS-850) and
the NR does not seem, to me at least, to be any better than that on the
TS-480 this K3 replaced.  And, I have experimented with all the various
settings available and am running the latest firmware.

Having said that, I remain 95% delighted with the K3.  The strong signal
handling is fantastic, I like the ergonomics and the tx audio is simply
excellent.  I would not swap it for any other radio.  But, the NB and NR
have not lived up to my (maybe unrealistic) expectations.
