And so that's your explanation for how 2 Joules per second can be
obtained from a source which is in fact producing only 1 Joule per
second.

Of course, I regularly obtain 200 watts of forward
power from my 100 watt IC-706. It's all due to
constructive interference.

If in fact the power delivered by the "100 watt IC706" radio was indeed
100W, and some directional wattmeter correctly indicated 200W forward, it
must indicate 200W-100W reflected which is indicative of a VSWR of 5.8,
which should have reduced power output from the IC706 markedly.

Taking another view, if the IC706 will tolerate VSWR of 2 before reducing
power (ie and still deliver exactly 100W), then the forward power would
be just 113W.

More likely, the IC706 levels its power output on the forward detector,
and runs 100W "forward" until the reflected power reaches about 12W
whereupon it reduces drive so maintain maximum reflected power =12W.

Did you make this example up on the fly, or is it the result of actual
observation on one or many occasions?
