[Elecraft] APF Results at an Old Timer's shack

[Robert Harmon]

For this old dog it is great !   
I very much like the peak, works very well at pulling the weak signal up 
for much better copy.   Congratulations Elecraft this is a super tool for CW !


Now the bad news.
My Yaesu FT1000 was switched in when needed on CW receive just for the APF to pull 
a borderline CW signal up out of the mud.   Looks like he will not be needed
anymore.  You have been a great radio FT1000  (sniff, sniff )

A few hours of listening to noise in a too-narrow filter and you start hearing things that aren't there, especially with some distortion thrown in, and ringing is distortion.
