[time-nuts] Strange oscillations

So it looks like Alberto has a hysterical crystal in a nice,
small package. The crystal easily meets the 10E-10 specification.
Too bad, I was going to suggest gravity waves and ask if the
magnitude of the oscillation changed with orientation of the
unit's case. But I'm not an astrophysicist so I don't know
the expected magnitude of the effect.
The specs on the reference voltage are not that tight. Would
the voltage reference junction have a tighter tempco than the
crystal? One would think so.
Anybody know the stability of the VP Oncore GPS?
Does a phase-locked loop have hysteresis from some digital
effect? Again, that seems unlikely.
Alberto, what's your weather been like? Clear, windy, cloudy?
