Thanks. I worry a little bit because my setup is not the normal thunderbolt running on the shelf or a rack. The oven for my oscillator is broken so I removed it from the circuit board and put it in a double oven with proportional controller that I built for a long ago project. The thunderbolt is in the outer oven running about 45C and the oscillator is in the inner oven running about 65C. The temperature rise on the display is probably the furnace in the house turning on this morning. I notice that the DAC voltage also rises and falls with the temperature change and wonder if that affects the oscillator in the inner oven.
I'll let it run for the rest of the week and see what happens.

I'd suggest running the OCXO calibration routine at some point. Everything is still warming up / settling out for the first week or two, so who knows where it will finish out at.

I hope it's ok that I attached a screen dump of what I have. Can anyone comment on the picture. It's been running less than a day and I don't know if what I have would be considered good as far as accuracy and stability is concerned. Thanks.
