[time-nuts] Help with TCXO

[paul swed]

Ok to answer part of the original question.
Indeed I have see the "clipped sine wave" as you stated and it has no
negative component.
Numbers of vectrons and other xtal oscilators look like that. No negative
supply nor transformers so thats what you tend to get. Its normal. But as
you say feed into a circuit to clean it up and all works just fine.
Regards
Paul.
