[time-nuts] injection locking crystal oscillator

[Thomas S. Knutsen]

Thank you for all the hints.
I did several experiments, but was not able to get reliable injection
locking, several times the crystal jumped some 10-20Hz down, and
stayed there.
Think I have decided to just remove the 10MHz crystal and drive the
oscillator from a external source.
