WWV & National Bureau of Standards in 1960 | Signal Phantom

Vintage and new photos of WWV / NIST I have collected over time - Boulder, CO March 5th 1960 scientist at National Bureau of Standards develop new atomic clock- Roger Beehler (left) adjusts atomic beam detector while Charles Snider pours liquid nitrogen into cold trap of atomic clock perfected in Boulder laboratories [now N.I.S.T.] Clock, counts vibrations of vaporized Cesium mined in South Dakota, measuring one second as 9,192,631,770 vibrations of the Cesium atom!
Signal recorded by Tyler Stampfli, amateur radio operator KA0KA in Fort Collins, CO.

@@calvinforcejr2382 The recordings are originally humans, WWVH is Jane Barbe and WWV is John Doyle, I believe. However WWV uses a computer to piece together the recordings to form the announcements you hear. I would think by now WWVH does too, but last I heard they were still using a mechanical system to piece together recordings on magnetic drums.
