[time-nuts] Plug and play GPSDOs was:(no subject)

There is one thing that make most GPSDOs not quite plug and play...  that is their need to know their location rather precisely.  They do this with a "self survey" mechanism.  The self survey can take several hours.  Most units can trigger this automatically if their location changes more than a specific amount.

You are better off manually triggering the self survey and saving the results in the unit.  Unless you do this,  the unit might go into self-survey mode every time the power cycles or might get confused trying to use the old location.
