[Elecraft] Suggestions for 10 MHz Signal Source for the K3?

In holdover mode (e.g., no antenna connected), accuracy is typically 
7x10^-10 for the Thunderbolt.  So, still quite good.  However, I don't 
recall if the typical holdover specs require that the GPS-DO first initially 
attain lock, then the antenna can be removed.
