[Elecraft] [K3] Transmitter Calibration Procedure

[Randy Farmer]

An update:

  I did a power cycle and carefully repeated the TX calibration 
procedure. This time I caught the requirement to set CONFIG: TUN PWR and 
CONFIG: PWR SET to NOR. This instruction appears at the beginning of the 
entire Calibration Procedures section of the manual. This time, things 
behaved better but the instruction to "adjust menu parameter" for the 
proper reading on the external wattmeter was still puzzling. Adjusting 
the VFO A knob had no effect. Finally, I turned the PWR knob on the 
front panel of the K3 and the output power changed. I was able to do the 
5W and 50W wattmeter calibration using this technique. I then 
re-executed the Transmitter Gain calibration using the K3 utility.

The PWR knob adjustment value still is incorrect. Setting the Tune power 
for 30W delivers about 36W and to get 100W out of the radio I need to 
back the power setting down to around 91. The level is pretty consistent 
from band to band.

This is no big deal, but I'm still not sure why the wattmeter 
calibration didn't affect the power control set accuracy. Am I just 
misunderstanding what's being accomplished in the calibration or is 
there still something wrong with the way I'm doing it?
