I'm in the middle of listening to "At The Tone", a CD full of recordings of the signals that National Bureau of Standards broadcast on short wave stations WWV and WWVH.
http://dodgeblog.nfshost.com/wordpress/?p=435 http://www.myke.me/ This is golden stuff for shortwave time nuts. It contains records of service changes, service failures, and implicitly the technological and political forces which drove them. It has the change from local standard time as UT2 (first Eastern, then Mountain as the station moved from Maryland to Colorado) and then to GMT rather than try to follow the 1966 law mandating daylight time. It has the announcement of a 4 hour interruption in broadcasts. It has numerous recordings of the Morse code broadcasts of the difference between the broadcast time and UT2. It has the 1973 announcements acknowledging that despite the voice announcments saying GMT the signals were already UTC, and the change as of 1974. Alas, what it does not have is a recording of the first leap second. -- Steve Allen <s...@ucolick.org> WGS-84 (GPS) UCO/Lick Observatory Natural Sciences II, Room 165 Lat +36.99855 University of California Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com http://six.pairlist.net/mailman/listinfo/leapsecs
