We were not measuring frequency but clock offset. The frequency offset
was estimated from the daily clock measurements.
If I remember correctly we got .1 uS accuracy.
We had several Rubidium, Cesium and later a H-maser frequency standards
and we kept continuous recordings (strip charts) of the

If you look closely at the picture, you'll see that it's an "L," but
there isn't quite enough resolution to say whether it's a 5245L or a
5248L. Probably 5245L because most 5248s had the hi-accuracy (for the
era!) standard and were sold as 5248M.

I was a lot of times at the other side of the link, the receiving end,
those days (and I also have no hair).
The procedure was cumbersome: you have to climb to the roof to manually
point a small parabolic antenna to the moon using handwheels and a rifle
scope. The antenna had an hourangle electr

I like how none of the push buttons in the panel below the counters have
