[Elecraft] [K3] f/w 2.73/1.98 power calibration

[Steve Ward]

After reading about the TXG VCE parameter I reloaded MCU 2.73/DSP 1.98 
and attempted to adjust the gain back to a reasonable level.  By setting 
TXG VCE to -3.0 dB I came close to my requested power output on the K3's 
meter, when set to 40w I get between 4-5 bars on the graph.  This is 
with the 5th bar flickering slightly on the ALC meter.

At the same time I also tried the ADC REF calibration and came up with 
4.967 v on my Fluke meter, so I set the K3 to 4.97.

It seems to me that having to set the TXG VCE to it's minimum setting 
suggests something is still not quite right with the new firmware...
