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.

Broadcaster: Time signal station VNG Lyndhurst Victoria Australia

Date of recording: December 13, 1971

Frequency: 4.500 MHz

Recption location: Ancaster, Ontario, Canada

Receiver and antenna: Hallicrafters S-52 using a longwire antenna

Mode: AM

Notes: Recorded on December 13, 1971, here is the announcement given by station VNG in Lyndhurst, Victoria, Australia transmitting with 10 kw on 4.5 MHz shortwave. This station was active from 1964 to 1987. Receiving location was Ancaster, Ontario, Canada. Amazingly, the recording was made on a cheap Demonstration Musicassette that had tape placed over the ends so it could be reused. It still plays today and was used to produce this digital version. The announcement is given twice and goes: "This is an Australian Post Office standard frequency and time signal transmission from VNG, Lyndhurst, Victoria on 4.5, 7.5, or 12 Megahertz." This was given during the 15th, 30th, 45th and 60th minute of each hour according to their QSL card.

Date of recording: May 21, 2023

Starting time: 1530 UTC

Frequency: 15.67 MHz

Reception location: Northern Vietnam.

Receiver and antenna: TECSUN PL-380 with long wire

Notes: An audio recording of Wavescan- the international DX program from World Adventist Radio on May, 21st, 2023. It is produced by WRMI in FL, USA. This recording was made by connecting the mic in port of my Android phone to my radio (Tecsun PL-380) tuned to 15670 kHz with a 5-meter-long wire as an antenna. The signal was transmitted from KSDA- Guam with a power of 100 kW. My radio has a band-width changing function so I used it to optimize audio quality, which resulted in the audio being muffled a little bit at the beginning. QTH: Northern Vietnam

Note that the frequency announcement at the beginning did not match with the actual frequency I tuned to.

Time signal station WWVH in Kekaha, Kauai, Hawaii was occasionally heard over WWV in Fort Collins, Colorado from my receiving post in Ancaster, Ontario, Canada in the 1970's, particularly on 10 MHz or 15 MHz. Here is a recording of their voice announcement from 1971, when they were still using the term Greenwich Mean Time as opposed to Coordinated Universal Time. The familiar "Aloha" is heard at the conclusion of the announcement.

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.
