it could be also that the pover supply drops the voltage under nominal load... looks Ok with no load....

Although the ower supply read OK with no load, I dug around in my junk and found another upply to replace it with. I just swapped it out and no more rebooting. Now have to wait until I get GPS lock and the thing stabilizes again. The failure was at an inconvenient time, as I was using the GPSDO to adjust n OXCO that I am going to put into a project. I've had the OCXO on my able, cooking for weeks.
