Lou,
You probably know this but it is worth saying again.
PEP is the peak of the RF envelope, or the short term peak
"RMS" or work power.
It isn't a one RF cycle peak, and it certainly isn't the
peak voltage times the peak current.
What Gary is talking about is the real PEP power, or the
highest very short term value of RMS power in a speech
envelope. Since the speech envelope it is not a two equal
steady tone signal that produces a sine wave shaped
envelope, the ratio of peak to average is probably much
greater than two.
None of this has anything to do with the individual RF
cycles, which are always a near perfect sine wave at the
operating frequency in a transmitter without harmonic
radiation problems. It's all about the envelope shape, which
normally is less than a few thousand Hz in frequency.
