I think the idea was to look for jumps in a crystal oscillator when it goes through the shadow of a total eclipse. My original suggestion was to look for LEO satellites which had conveniently monitorable oscillator frequencies. Someone else suggested using Inmarsat (because they have a L-band pilot tone), but I think the Inmarsat birds are in Clarke orbit, so you'd have to pick your ground station location (essentially in line with the sun and the bird) to do the test. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
