[time-nuts] HP5334B with 10544 OCXO

[ed breya]

Could it be that since they are much older (on average) than the 
10811s, that (if they've been running) they would have much more 
accumulated time, so in a more stable part of the long term drift curve?

I have had several HP-5370's with the 10544 oscillator.   They 
consistently have much less long term frequency drift than the 
10811's.  If they  have not been powered on for a long time,  they do 
take a couple of months of power-on aging before they settle 
in.
