Matthias,
You are correct, having spent hours looking at all the stable areas
and cooling and heating the gpsdo I find that when it reports that it is
116.25 F then it is stable.
So now I guess I need to figure out why it is so picky. I will measure
the current draw from a cold start and see if I see the oven warming up
and then stabilizing and then heat and cool it and see how it reacts,
and also look at the electronics and see if an area is overly sensitive
to temperature.
Thanks
Kevin

The temperature curve seems to show some correlation to what is happening with
the DAC. Seems that the DAC and OSC jumps are mostly during periods of some
thermal perturbation.

Matthias
