What is a further issue is why the FCC decided to drop steady DC input
(easily measured with a plate current meter) in favor of making PEP
output
measurement the new criterion by which transmitter power is to be
measured. The only thing I can think of is that there were, in the far
past, some AM amateurs who were running some form of ultra modulation
or
super modulation and putting KWs of audio on a 1 KW DC input to the
final
signal and the FCC didn't like that. Maybe if any of you have some
background on this, you could mention it.


While possibly (probably) true... DC was easy to measure (by hams) and RF
power difficult to measure in the early days. As time progressed, RF power
became easier to measure and, after all, was the thing which would cause
trouble as far as interference was concerned.

Even us guys with a commercial ticket used DC measurements to determine
input power; it wasn't a ham thing. Watt meters were used on lower powered
equipment, but it wasn't a requirement. Your "after all" comment is silly.
