I thought that I had read of designs where a switching
mechanism would allow the amp to run in Class C or AB1
mode.  Is the reality that attempting that not recommended?

So an all-mode transverter either has to run inefficiently
in AB1 mode or utilize dual TX sections, one for SSB
and the other for AM/CW/Digital/FM?

Is DSB likely to be harmed as badly as SSB by Class C?

I know that I should know that but I don't remember
what I used to know about that!

I could consult a Handbook but it is more entertaining
to have a keyboard-Internet-keyboard QSO.  :-)
