[Elecraft] K3 NR

[James Sarte]

Uh oh.

This isn't good news.  I just installed 3.27, but haven't had time to test
out the updated NR algorithms.

Prior to 3.25, my biggest complaint was lousy SSB NR performance.  3.25 did
a good job addressing those problems, however a lot of CW operators
complained.

Now if what you say is true, then that's pretty unfortunate.  Perhaps Lyle
is having difficulty finding a happy medium.  The problem with DSP noise
reduction is you can't really have a particular algorithm do both things
well; CW or speech isolation.  At least none of the DSP NR units that claim
to do both that I've tried were able to do it well.  It was either one or
the other.  The BHI ANEM module is a perfect example of excellent SSB
isolation but lousy for CW. 

I'm too knackered to test the NR tonight, plus the bands are dead anyway.
Hope other reflector participants chime in.

Well the SSB folks lose out yet again on the latest FW revision. Just when
the next to useless NR was made to work we have yet another version that
favours one mode over others.

Rather disappointing result but that appears to be the way of the k3 world
at times.

Great radio for some but so great for others perhaps..:-(

Don't know could be a replacement but the search has started.
