Since, I assume, you are most interested in time/frequency I recommend you use the position that each device self determined. To verify the 10 Mhz output it is easy to compare one against the other. If you don't have a frequency meter with enough digits, just use a 'scope syncing on one and see if the other trace is stable over time.
The other thing that comes to mind: were all GPSDOs taking the measurements at the same time? If not, you should EXPECT different positions to be reported (within the specifications of the receiver) Michael/K7HIL On May 2, 2016 4:03 AM, "Joseph Gray" <[email protected]> wrote: > Now that I have three (maybe four) working GPSDO's, I'd like to set > the GPS coordinates the same on all of them.
