Ed and others; How about devising a real world SSB measurement for off
chanel crud when modulating with a wide bandwidth Human Voice.
I don't have any faith in rewiews using two tones for off chanel racket.
I have seen many modern ALC circuits completly fall apart when hit with
an real composite, human voice.
The shot noise produced off chanel with initial audio attack can be
terrible with most supposed " good " ALC circuits.
Notice my comments " No ALC might be better on SSB Transmit " about half
way down the page.
I almost conclude reviews only cover CW, then again klick, klick ??
