The correct formula which accounts for both the center tap detector and the
diode drop appears in the DL1 manual.

Subject: [Elecraft] DL1 20W Dummy Load
I was doing a calibration of a KAT2 I just built and had a significant
error to adjust for Forward power (displayed power was ~30% of measured).
When I looked closely at the DL1 I noticed the trace to the detector comes
from the center of the 50 ohm load. That means the detected voltage is
across 1/2 the load (25 ohms) and changes the power calc to V^2/25 = P vs.
of V^2/50 = P. Can someone confirm this?
Thanks...
