I do agree with you Frank, that Audio power draw is very close to SSB power
draw from the Power supply, Battery, or alternator in a car system.
I do not run RF compression even if it does in the amp, and if it does
compress, the cap still help in filling out the audio ripple on the supply
line.
..
O well enough on this.

I haven't given up on you yet, Tnom:

You have an audio signal of a given frequency, say 400 Hz. Simple enough?
Ok.
Now, compress the **** out of it. Is it still 400 Hz? YES! Now if it
is -still-
400 Hz then it -still- crosses zero twice per cycle, right? YES! And
unless you
have compressed it into a perfect square wave, it still spends some time
where
the signal is less than full power, right? RIGHT! Now pick any point on
the
audio wave. That point represents an equivalent amount of RF power, right?
RIGHT! Now one of the characteristics of SSB is that the RF power
fluctuates
WITH THE AUDIO WAVE from zero to peak, right? RIGHT! So does that mean if,
at
that point, the RF power output is xxx watts, for an amp that is 50%
efficient,
the input power will be 2 * xxx watts? YES! Can you pick any point on the
audio
curve and the same thing will be true? YES! Therefore, we can conclude
that the
DC current drain on the power supply is proportional to the audio. And you
know
what, Tnom? IT IS!!! Does it matter if the audio is compressed? NO!!!

Do you get it yet? Or are you going to pout and whine about me trying to
distort
the truth?
