Owen, there was absolutely no reason for anyone else to do any
additional experiments. Your own experiment proved that the Bird
wattmeter was ignoring the 4.1667 watts of reflected energy flowing
through it when installed in the 75 ohm environment. You proved
exactly the opposite of what you were trying to prove.
