There's a few 'OCXO' designs out there, I'm not qualified to comment on the
timenutty quality of them but someone else mentioned Hans Summers offerings
and I would offer Roman Black's simple design (if it's not been mentioned
I've no idea if it's useful but it's ridiculously simple to implement.
Both Hans' and Roman's designs are 'on the list' of things to try for
myself at some point.
