[time-nuts] Strange oscillations

I should add one more thing:   If this OCXO uses an AT cut crystal, the CRYSTAL will have some 
hysteresis and 1e-11 will be a very challenging spec.   True SC's do not have this effect at the 
quartz but mounting structures or other components in the oscillator can.   Of course, not all SC's 
are hysteresis free.
