Evening Mark,
Yes my K2/100 #3255 delivers as is without any mods, but it is good to know
about R14 in case something gets "tired", thanks. When there was the
discussion about the effect of inductive resistors on the KPA100's gain, I
dug into mine. Although its power output on CW and SSB was comfortably
within spec on all bands, I was a little concerned about the possibility of
unacceptable intermod products. Fortunately the frequency of minimum gain
fell outside of our bands, and the six inductive resistors within the PA's
feedback networks appeared to be the main culprits.

Your comments pretty well mimic mine I made privately to Kevin as well.
However, I found that I had to increase the mic gain on the K2 slightly by
changing R14 on the SSB module to 10K (from 1k originally) and now my K2
works great with my Heil headset. Did yours work as is without the mod?
I've suggested this mod to others as well and they found that it works
well for them as well. I can't take credit for the mod itself as I found
it here on the reflector quite some time ago, I just passed along what
worked for me.
