[Elecraft] K3: Still unable to set power correctly in DATA A (sigh)

I recently installed the latest firmware and ran the TX Power calibration
wizard - nice work. However while running WSPR (a sound card data mode) I
was somewhat annoyed to find the K3 power meter showing about twice the
output power I had selected. Checks using my own power meter confirmed that
the K3 is putting out about twice the amount of power specified by the power
control when DATA A is used (though the exact difference seems to vary a bit
from band to band.)

Using TXG VCE is NOT the answer, as the output power in SSB (and in CW) is
regulated correctly. Using the maximum TXG VCE -3.0dB I still can't quite
get the power down to what it should be, but if I do that, SSB output is too
low.

Forgive the note of frustration but I am frankly very annoyed and fed up
that after all this time and numerous reports of this issue from me and
several other people going back several months, the K3 is still not capable
of performing a simple basic function like regulating the output power to
the level the operator requests. I am seriously considering selling the K3
at this point, as I am losing confidence that Elecraft has any intention of
fixing this issue.
