BROADCASTER: WWV
DATE OF RECORDING: December 08, 1991
STARTING TIME: 0218
FREQUENCY: 5000 kHz
RECEPTION LOCATION: Rockford, Illinois, USA
RECEIVER AND ANTENNA: Unidentified boombox
NOTES:
NIST Radio Station WWV as it sounded on 8 December 1991 at 0218 UTC.
Due to the high cost of maintaining the aging drum-based voice announcement machines, NIST implemented a digital voice announcement system in 1991. The new male voice, belonging to Eric Smith, started at WWV on 13 August. The voice of WWVH belonged to Johanna Stahl. The voices were sorely lacking in high EQ at first, but were sharpened with an audio filter on 27 August. The modification did not help, and after months of equipment failures and complaints about the poor quality, NIST retired both voices on 11 August 1992.
An excerpted version of this recording is found on "At the Tone: A Little History of NIST Radio Stations WWV & WWVH." This unedited version is being shared by special arrangement for the Shortwave Archive.
Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:
KC2XIO was an experimental radio station operated by the National Bureau of Standards in Boulder, Colorado between July 1970 and May 1971. This was to gather information in preparation of the format change for WWV and WWVH which happened in July 1971. Here are two recordings of their voice announcement (one male and one female) as heard in Ancaster, Ontario, Canada on a Hallicrafters S-52 receiver that was hooked up to an outdoor longwire antenna. The frequency used for these test transmissions was 13560 kHz shortwave.
Reception location: Ancaster, Ontario, Canada
Receiver and antenna: Hallicrafters S-52 using a longwire antenna
