Hi Lyle,
I do not know if we all might be talking about various ills with similar
symptoms. It might be that more than effect might be behind the various
observations, imho.
What I have, to the best of my memory, observed in various firmware
versions is that there is/was a tendency for the K3 to have lower output
in SSB on both(?) sidebands than in CW or tune modes. The output is at
times 1dB less and at times 6 or more dB lower. This effect is stronger
at lower power levels than at higher and usually occurred after changing
the power level request while in SSB.
This was at times a major fubar, but in the newer versions of the K3
firmware on my K3 (#67) the situation has greatly improved. Because I
had sent more than one mail to Elecraft, in the distant past, about this
and the situation, at least for me, has been improving, I did not want
to harp about it.
For example, during our expedition to OY in early July such weirdness
only popped up very rarely. I have not tested the newest beta firmware
for this (yet).
I have the 2.7kHz filter in my K3.

The problem I have been aware of is the LSB/USB power output difference.
That seemed to be confined to 2.7 kHz filters, was related to the
center frequency offset, and should be fixed in the latest beta firmware.
