[time-nuts] Why a 10MHz sinewave output?

[Craig S McCartney]

Actually, I do have an earth available for calibration to my lab.  It's
just outside the window.  During the day I can take sun sightings, and
during the night star sightings (barring cloudy weather).  I cannot
measure the length of a second as accurately as other lab equipment can,
but the expensive equipment in my lab that measures the second
accurately cannot tell me time-of-day or day of year. (with the
exception of a WWV or GPS receiver).

Yes, but you don't have it hanging in a neat position in your office,
living room or lab, now do you? Besides, if you are a time-nut your rock
will be more time-accurate than the real thing. :)

I haven't special ordered a backup earth for my lab, or at least I won't
admit to it, as you all know that I have at least three operational and
a few stand-bys to put into operation in case I need to service one of
them.

Cheers,
Magnus
