Hi Steven, You can contact me off-line about this if you want more information.
Being someone with plenty of cesium clocks I looked into his claims in the late 90's. His cables and electronics were not at all temperature compensated. It's a simple mistake we all make at one point or another in our time-nuts career. Once you deal with tempco correctly no one has problems like he saw, whether your clocks are as old as the one he used in 1991 or modern ones that are ten to a thousand times more accurate. Note he ran his experiment for 178 days. If you run a ground temperature experiment for a full year (or years) you get complete temperature cycles; if you happen to pick only half a year, starting early summer as he did, you get a slow ramp. When you combine diurnal changes (which he saw) with half-year ramps (which he mis-interpreted) you get a solar-sidereal effect that looks extra-terrestrial. Roland was a little too eager to prove aether exists and textbooks were wrong. Unfortunately he died shortly before I could email him about his methods and raw data. That was, what, 15 years ago. /tvb www.LeapSecond.com ----- Original Message ----- From: "Steven Kluck" <[email protected]> To: "Discussion precise time and frequency measurement" <[email protected]> Sent: Tuesday, August 27, 2013 8:25 AM Subject: [time-nuts] de Witte's Experiment I am new to this group, and my main interest is time keeping/ time signal reception, but all of this frequency talk is catching my interest. If I had a couple of extra cesium frequency references, I would want to try Roland de Witte's experiment. Simple and fascinating! Position one clock about 1500 meters to the east of the other, set up a long (temperature controlled) coax cable between them, and compare phase from the 10MHz outputs as the earth turns. The results were enough to make de Witte a fairly unpopular gentleman until his death. --Steven Kluck _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
