If in fact the power delivered by the "100 watt IC706" radio was indeed

which should have reduced power output from the IC706 markedly.

Nah, no problem.

Connect your rig through a half wavelength of 250 ohm ladder line to a
50 ohm load. Presto, 200 watts "forward power" and 5:1 SWR on the line,
and the poor ignorant Icom doesn't have any hint that all those waves of
power or energy or whatever are bouncing around on the line, trying
desperately but unsuccessfully to overheat the final or whatever they're
supposed to do.

Of course, it would take a 250 ohm directional wattmeter to read that
"forward power" or SWR. But we don' need no steenkin' meter -- we know
it's there, don't we?
