[Elecraft] Low power draw, low power out?

[Nick Waterman]

K2 #5209, Set at 5W, TUNE, I'm drawing only 1.0A, and should expect 1.3
to 1.6. Similarly, set at 10W TUNE, I'm drawing 1.02A, not 1.8 to 2. I'm
pretty sure I'm not putting out the power I should be, and DL1+DMM also
implies I'm only putting out about 2-4W, not 5-10. This would be at
7100kHz during 40m TX alignment. Is there some way to calibrate the
power output using DL1 and my DMM, or have I built something wrong?
