[time-nuts] Question on crystal jumps

[SAIDJACK at aol.com]

Hi Steve,
 
the jumps are very slow in their frequency change, so the crystal filters  
would just follow the frequency drift. I have seen these jumps take from a few  
seconds to 20 minutes or so. Of course in a Rb they would be compensated by 
the  Rb pulling or pushing the crystal onto the proper frequency.
 
Also, the additional crystals in the filter will very likely jump too, so I  
would expect the overall performance to actually get worse.
 
bye,
Said

oscillators have these jumps, I wonder if the output of the  rubidium
stage could be just passed directly through a multi-stage xtal  lattice
filter to clean it up and use that directly and that may  circumvent
the xtal jumps people are  seeing.
