The E1938A oven has exceptionally high thermal gain so variations in the
OCXO frequency due to ambient temperature changes may well be insignificant.
Before proposing drastic/dangerous measures David should attempt to
measure the E1938A frequency variations as a function if temperature to
see if the frequency change is actually significant.
Making such a measurement is likely to be an extremely
difficult/challenging  task. Even so measurement beats speculation
everytime.
