The DC input power follows the audio input, compressed or not. Is that concept
too difficult for you to comprehend?

Trying to create a divergence away from the truth?

Hardly. I'm trying to make you understand a fundamental concept of radio
communications that has eluded your meager education.

The truth is not gained by equating DC input to output. The truth is
gained by comparing SSB audio compression levels to that of HI- FI
audio compression levels.

You are truly lost.

More accurately you are truly lacking in common sense.

A compressed audio signal at its highest compression would
approach a single tone or carrier as far as a SSB amp goes. With
this much compression no reasonable amount of capacitors can
be useful on the 12 volt lead.

On the other hand just and intermittent spike here and there will only
require a minimal amount of capacitance on the 12 volt lead and can
make a difference. If you graphically plotted the capacitance needed
for total compression (carrier), to no compression (spikes), then
you would have a linear graph that would show that the amount of
capacitance needed is directly related to the percent of the duty of
the amp.

The caps work better if the have time to recover. If they can't
recover then the are useless. A SSB signal has more compression than
a HI-FI signal., so dx1600 with one farad on SSB would be one of those
points in between. total compression and no compression It wouldn't
have adequate time to recover in order to be worth the cost.
