I received the 10 MHz OCXO from Paul today.  From a cold start, 
approximately 65F, it took only 3 minutes for the oven to warm up and 
start regulating.   The initial 12 volt current was only 500 ma and went 
down to about 150 ma after warm up.  With one channel of a dual trace 
scope triggered by 10 MHz from the GPS locked output of a HP Z3801 the 
OCXO trace on a second channel was barely creeping after the 3 minute 
warm up.  I tweaked the OCXO trace dead on with the Z3801 and after 
several hours it has not moved.
