[Elecraft] APF For K3: progress report

[Ken Kopp]

Hi John!

Welcome to the list....

You'll find much discussion on here ... some of
interest to you and some not, but overall, a great
source of information.

"APF" refers to "audio pass (or peaking) filter", 
a feature common on many radios, and sometimes 
known by other names, depending on the manufacturer.

It's best represented in the FT-990 and FT-1000D, IMO.
