[Elecraft] K3 Firmware Bug? Power Reduction After ATU TUNE

[Chuck - AE4CW]

I am seeing an approx. 20% reduction of peak SSB power after pressing ATU
TUNE.  This occurs at both 50 and 100 watts into a high-quality dummy load
as indicated on the K3 RF bar display and my external LP-100A wattmeter. 
Bypassing the ATU does not restore the peak power, so I don't think it's
caused by the ATU.  Pressing TUNE does restore full peak power until I press
ATU TUNE again which causes the peak power to drop by approx. 20%.  I see
this behavior in firmwares 2.02/1.77 and the beta 2.15/1.84.

I presume this is a firmware issue and will report to Elecraft but wanted to
see if others are experiencing the same problem.
