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.

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.
Live off-air recording of some of the last day of programming from the Raidió Teilifís Éireann (RTÉ) Radio 1 longwave station on 14 April 2023 beginning at 11:55 UTC on the frequency of 252 kHz. The signal originated from a transmitter located at Clarkestown/Summerhill, County Meath, in the Republic of Ireland, reported to operate with a power of 150 kW during the day (and 60 kW during the night). The transmitter was capable of operating at 300 kW. The station used a 248-metre high single-mast antenna.
RTÉ Radio 1 is a general-interest, news, talk, and music station. It now uses FM, satellite, streaming, and cable services.
The recording starts with the final minutes of the "Louise Duffy Show," followed by the "RTÉ News at One" (which featured reports on U.S. Pres. Joe Biden's visit to Ireland) and then the first 13 minutes or so of "Liveline," an interview and phone-in chat show. The recording ends with an announcement of the shutdown of the longwave service.
Reception of the 252 kHz signal was reasonably good but it suffered from slight co-channel interference from a station in Algeria and local noise at the reception site.
RTÉ Radio 1 programming on 252 kHz ended at 23:03 UTC on 14 April 2023 and was replaced with a repeated announcement of the cessation of broadcasting on longwave and information about other ways to hear RTÉ Radio 1. It begins with the RTÉ Radio 1 interval signal "O’Donnell Abú." Examples of the announcement are included in the second three-and-a-half-minute recording which starts at about 12:34 UTC on 15 April 2023. In this recording, most of the interference has been removed by an audio filtering technique. The closedown announcements ended on 18 April 2023 at 09:59 UTC and the transmitter then fell silent.
The broadcasts were received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in synchronous AM mode with 5.08 kHz RF filtering.

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.
