Many years ago during the 1980s I built and had one of these Heathkit Most Accurate Clock. I had a long wire running across the ceiling of the apartment for an antenna. Eventually this clock wore out and failed after a number of years.
Hi Greg! We used this at Jicamarca as a time source for some pre-GPS experiments in the early 1990s. Note the RS-232 port on the back; I believe you can get a TTL level signal out that way. I think the "World's Most Accurate Clock" is a bit of an overstatement :)

nice collection of test equipment you have!
Love it! I have one still in the box that needs assembly. Thank you for showing this. It helps me to get motivated to get busy building it. 8-)

I believe that’s tenths if seconds, not hundredths ;-) Very cool though.
Thanks for sharing mate!
Can you show them one beside the other to see how they change digits at the same time?
Can you offer a radio astronomy course through MIT?
