I don't know how many time nuts are interested in this but
you need to realize that the first hint that the Earth itself was
an unstable timekeeper came, not from quartz or atomic
oscillators, but from these astronomical pendulum clocks.
Hi Connie,
My life has been a little complicated lately, but it will settle
eventually :-)
I was surprised to be so close just by ear. 20m was hard because of QSB,
but 40 and 80 were good, with strong and stable signals.

My mention of Alfred Loomis prompted me to get the book out and I found

No, that is correct. The Accutron has a predictable position error, gaining or
loosing a couple of seconds a day depending on whether the tines of the fork are
pointing up or down. (gravity effects!). They are calibrated depending on
whether it is worn on the inside or outside of the wrist, or

If I'm not too late, I would also like one - or preferably
