[Elecraft] GPS Disciplined 10MHZ source from China

[Dave B]

OK, so what was the "Item Number" on the bay?   As I'm unable to find
that seller to see what exactly it was you purchased.

Or, what is the make/model number of it (if it's an ex commercial item,
such as a Thunderbolt.)

The devil is in the detail with these things.
