[time-nuts] FE-5680A Mechanical Question

[Chuck Forsberg WA7KGX N2469R]

Both of my units came with a stored preset of 0.

Giving the second unit an offset of 0 results in an
84 second period for a 360 degree phase procession
relative to a Thunderbolt's 10 MHz output.  Call it
100 instead of 84 and we get 1e-9.  Measure the
distance to the Moon within a foot or two.
