[Elecraft] OHR WM-1

[Don Wilhelm]

Paul,

The OHR WM1 was based on the QRP Directional Wattmeter by Roy LeWallen, and
although I don't know how OHR may have changed it, I would believe that the
calibration procedure is quite similar.  You may want to check the QRP
Directional Wattmeter article originally published in QST Feb 1990 and
appeared in several editions of the ARRL Handbook and Antenna book after
that time.

73,
Don W3FPR
