Hi Dave,
You're correct about using real data to determine what is really going
on. If you want to know how much the voltage drops on an SSB voice peak
the "good voltmeter" you refer to may need to be an oscilloscope. Using
a slow responding meter you could easily see what the voltage drops to
with key down CW for a few seconds, and then guess that SSB voice peaks
produce a similar drop. With an oscilloscope, the voltage drop data on
SSB peaks would be more like "real facts".
