[time-nuts] RFX GPSDO - Anybody played with one of these?

[Bob Camp]

Hi

The rated temperature stability of the OCXO is not "super good". You will
see more frequency shift on it than say the TBolt OCXO, far more than a
DOCXO.

That's not at all saying it's a bad part. For Time Nut duty, I would try to
keep it in a fairly benign ambient situation.

Why not.. granted it's easier with large mass and large insulation, but 
ultimately, it's all about the closed loop gain of the temperature 
control loop.  With small mass, the time lag effects will be small, at 
least.
