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.
