[Elecraft] K3 new V3.25 NR not so good for CW week signal

[K9ZTV]

Jaime . . .

Many FT-1000D owners (and non-owners who have used them) have urged 
implementation of an Audio Peak Filter in the K3 for weak-signal CW 
work.  Only those who have used a 1000D can appreciate why this request 
keeps recurring.  It has nothing to do with fondness for a venerable old 
rig, and everything to do with the performance of the APF.

I continue to marvel at the way white noise and miscellaneous garbage 
are eliminated at the 50 cycle setting of the K3's DSP.  But as good as 
it is, the signal remains what it is -- there is no peaking as there is 
with the 1000D.

Several of us have discussed this with Wayne from the first days of 
production, and while it may someday be addressed further, for now the 
issue is moot.
