Friends,
maybe we have to sort problems with SSB power level to permanent
problems and temporary problems.
Permanent lower level is possible to cure via VCE gain setting (I
suppose & hope).
Temporary problems are more complicated. I remember my problems with
miliwat output levels via KRX3 vith certain version of F/W, when firts
(after switching on) SSB TX attempt was 6 - 10dB lower below CW or
TUNE level. Just after one dit or dash in CW mode and going back to
SSB it was OK, level was like on CW (measured in 2tone test). It was
caused by combination of f/w level (maybe corrupted) and using TUN PWR
level other then -norm-.
Shortly after u/g to 2.10 (if I remember correctly) and switching TUN
PWR to -norm- this problem on miliwat output level dissapered. (and
now I am using 100mW on ANT port so not checked miliwat KXV3 output
intensively during last weeks with newest f/w).
Also I am not sure if such kind of temporary problems are also
reported with 10W version. (SSB power temporary dropped).
Or is it mainly with 100W version? Any other experience with miliwat
output?
Hope in Elecraft support they are tracking all reports and testing
reported behaviour to keep clear picture and plans for possible f/w
updates/bug elimination.
Maybe will be good to see some more comments from Elecraft support to
reduce individual doubts etc...

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.
Have you tried setting Config: TXG VCE to 3.0dB?
