Well, as far as I'm concerned, "ya done real good, Kid.". :-)

Have you investigated using controlled-carrier modulation rather than just 
straight screen modulation?

I have always really liked CC modulation. And it works very well with a linear 
amp.

In fact, I had planned to use that CC method with the dynamotor-powered 
"de-chopped-to-ribbons" "ARC-5" transmitters I have here.

If you carefully zero-beat an SSB station, most don't even realize you're 
actually on AM. :-)
