[Elecraft] APF For K3: progress report

[Andy Faber]

Wes,
  If you are running on 160 or 80 in a contest and a weak signal calls you 
slightly off frequency, it's handy on the FT1000D to move the apf freq 
around to find him and enhance his signal.  In theory you could do the same 
with the RIT, but it can be easier to move the apf, particularly if there is 
more than one weak signal.  Maybe it's just personal preference, but I do 
like that feature.
  73, andy, ae6y
