Have you EVER heard of a ham getting a citation over the p.e.p. rule, in all 
the years since Johnny Johnston and his henchmen ramrodded that rule into 
Part 97?

A CLEAN SSB signal running a few hundred watts average power will develop as 
much p.e.p. as an AM transmitter running the same carrier power.  Consider 
that many, many SSB leenyars typically run  one or two tubes like the 4CX800 
tubes or better.

Actually SSB got hit just as badly as AM with the new power rule, but the 
SSB'ers just ignore the distortion, and let their leenyars flat-top on 
positive peaks, to bring the average power up to a kilowatt or more.

Which is a worse violation - a few instantaneous peaks above 1500 watts, 
each lasting less than a thousandth of a second, or flat-topped waveforms 
that generate spurious distortion products 5-10 kc/s up and down the band 
(and often much further)?
