Yes I do have the KAT3 installed.  Mine is a factory built rig, so I guess I
don't have the option of replacing it with the KANT3 board, but will call them
tomorrow about it.

I also discovered that when using CW while in SSB mode on all bands and then
going back to SSB without changing anything was causing severe overdrive
patterns on my monitor scope, but only if I used more than 100 watts of power on
HF through 6m.  It's not a problem with any of the XV series XVTRS I have.  When
I notified Elecraft they said they knew about it and were working on a firmware
solution.  You might want to check on that also.  I wouldn't have noticed it if
I didn't do a lot of weak signal work on 6m and up, where using CW and SSB at
the same time is advantageous.

Thanks for the info.
