Reply: True. I have all the precision oscillators I need. Four Rubidiums and two high stability crystal units. Four nice sized salvaged HP cases that have working power supplies. So all I have to do is install the oscillators then synchronize them with my two Lucent GPS receivers. The VLF receiver is for a cross-checking the GPS and serving as a backup phase lock source.

Wrote: which I have been monitoring to 10-12 for 14 mos now and it is stable. Reply: True, mostly. An article I had, but lost, explained that rubidium disciplined oscillators had better stability and explained why Allan deviation charts didn’t really give a true picture. So that is why I want to synchronize mine.
