[Elecraft] APF For K3

[W2bpi1 at aol.com]

As Don says I find the audio filter very useful in my K2. I also have a  
Nescafe filter kit from the New England QRP Club that works very well on all 
my  rigs including the K2. My old homebrew rcvr built around a BC453 with 
85KC IF's  had a homebrew Q-multiplier that was gud at peaking or nulling a 
signal. Some of  the gud ol da stuff if it were sitting beside my new rig would 
probably not be  as gud as I seem to remember. Whoops got off topic 
thinking of good ol  days. Love my K2!!!!!!!!!!!!!!!!      Geo/W2BPI
