Yes but but the t-bolt "remembers" the corrections is was applying and
continues to apply them whenthe GPS signal goes away.   I'm pretty sure one
of the things it remembers is the aging rate.

I know the "real" uP controlled XOs use programmed data for aging rate and
temp compensation the t-bolt gts it's own data by comparing with GPS.
