[time-nuts] Looking for information on True Position GPSDO.

[Bob kb8tq]

Hi

If you *do* go swapping around OCXO’s (or whatever) on a GPSDO board, 
it’s very nice to be able to change the internal “magic numbers” to get the 
control loop running properly again. The TBolt kind of spoiled us all in that 
regard. Most GPSDO’s are not very user friendly in this regard ( = you can’t
get at the numbers you need to change).
