[sdiy] Favourite VCO designs

[cheater cheater]

I believe David Dixon is working on a VCO that incorporates the SSM
based exponential converter. Correct me if I'm wrong, David?

If it's finished it could turn out to be my favorite VCO.

The exponential converter design makes VCOs based on it very very stable.
