WWV/WWVH

At The Tone is the first comprehensive audio survey of NIST Radio Stations WWV and WWVH: two legendary shortwave radio broadcasters whose primary purpose is the dissemination of scientifically precise time and frequency. Comprised of a 74-minute audio CD and a 32-page, full-color booklet, the set represents a huge cross-section of the stations' "life and times," including recordings of obsolete formats, original voices and identifications, special announcements, format changes, "leap seconds," and other aural oddities from 1958 to 2005.

Better than excellent.
