[Elecraft] Wattmeter for K3s Calibration

[Clay Autery]

K3S Manual, Revision A, May 26, 2015, page 52, left column, half way down...

"If desired, the [TUNE] power readings can be calibrated, This must be
done at 5.0 W, 50 W (K3s/100 only), and 1.00 mW.

IF you read this page, you find that the procedure requires a 50-W
capable dummy load (minimum), an "accurate" wattmeter, and for the
"Milliwatt-meter Calibration", "an accurate RF voltmeter".
