[Elecraft] K3 APF Effectiveness

[Don Cunningham]

Gentlemen,
I am not a CW operator (yet) as I have let my 1960's Navy training go to 
pot, but might I suggest that something might be overlooked in this 
situation with the APF seeming less effective??  The common thing mentioned 
is that "changes on one area often effect other areas" in the firmware.  Is 
it possible that the change to width (I believe that was the parameter) from 
10 hz to 5 hz could be somehow causing this "difference" that some are 
seeing??  Just a possibility from a bystander.
