Richard's numbers are average for what seems to be the RF component of
the waveform. It does not include any variations cause by modulation
characteristics.
A single number does not exist!! An average value for my voice
characteristics will be different from an average value with your voice
characteristics, etc.
The spectral and intensity characteristics of each voice is different
and will cause the instantaneous and average V/I ratio in the finals to
vary. Therefore, a single number does not exist.
It may be possible to develop an equation with variable functions for
spectral and intensity density functions to modulate the output but each
solution would be unique.
A nice thevinin model would be a constant voltage, example 12 volts dc,
with a dynamically varying source resistor. The source resistor has two
components in the modulation scheme: 1) the RF frequency variation,
constant frequency, 2) and the second term the audio spectral power
density of my voice. This would be loaded by a constant 50 ohm load.
Anyway, it's nice to think about. Averages are much easier to work with
though!

Such a number must exist.
