Tom the problem is easy to observe by cooling the OXCO with a fan and 
watching the EFC change.
I like to think of the issue in EFC steps. The OXCO's internal ground 
bounce is about 100 DAC steps. A fresh off the shelf Z3816 main board adds 
an additional 4mV of ground bounce so the total variation is a fraction of 
1000 DAC steps.
