Yes, and if you compare the total energy dumped into the
ionosphere by ham radio operators even during a contest, it's
a piddle compared to what the international broadcasters
are pumping out into their curtain arrays on most days. And if
such an effect were present, it could easily be ferreted out
with a carefully controlled experiment. I see no evidence as
of yet that the subject experiment was carefully controlled
(aside from perhaps s-meter calibration).
