When I fire up the big russian 3.5KW linear into a high swr, I don't
have to guess about where the reflected power is going at the xmitter,
the nice red glow on the plates are an excellent indication when they
begin dumping unknown amounts of power as infrared radiation ... when I
grab the coax (150 ft. run) and feel its warmth, I even wonder about how
much power it takes to elevate it's temp!

John,

With that insight and rigorous development, it must be time for you to
publish a book.
