[Elecraft] K2 SSB adjustment

[Mike Geddes]

The audio quality on my K2 was pretty bad on SSB, transmit and receive. I 
followed the SSB manual advice and adjusted BFO1 using Cal Fil on upper and 
lower sideband (on 80 meters) until I got it sounding pretty good. Not 
perfect. But pretty decent. I then tried to transmit on 10 meters upper, and 
the SSB quality was terrible.  Like it, too, needed adjustment. I was under 
the impression that doing this once on any HF band would work for all. Is 
this not true? Any suggestions for getting the SSB sounding good on this 
fine rig? (FYI, I was transmitting for testing of audio quality and feedback 
on my initial adjustments, and had nearby ham helping me listen and offer 
suggestions. My rig is wired for Kenwood mikes, and I was using the MC-43 
and a Heil Pr-20 for testing.) Any thoughts and suggestions are appreciated. 
I want to get the SSB transmit and receive sounding as good as possible.
