[R-390] Best approach for SSB mod on R-390A

[James A. (Andy) Moorer]

Indeed - doing it well will be quite difficult. I'm not surprised that there 
are very few commercial implementations, and those that exist are probably 
reserved for military or clandestine uses. That's where the high-end R&S 
and DRS receivers play, of course.

I haven't tried to implement this specific case (synchronous detection for 
radio), but I have done similar things about synchronous extraction of 
signals from noise, and I can confirm that it is not simple and very hard to 
make it work well. There are doctoral dissertations written on these things 
. . .
