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.

Reception location: Ancaster, Ontario, Canada

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

Prior to July 1, 1971, time and standard frequency station WWV in Fort Collins, Colorado was giving ID's in Morse code as well as voice every five minutes. They were best heard here in southern Ontario, Canada on 10 and 15 MHz.

Reception location: Ancaster, Ontario, Canada

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

Early in 1973, WWV made this announcement that they would make regular broadcasts of planned ATM (Apollo Telescope Mount) schedules by the new Skylab space station.

Reception location: Ancaster, Ontario, Canada

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

Radio Delta broadcasting in English and Dutch on the shortwave frequency of 6060 kHz. Recording made in Europe July 8, 2023 at 1836 UTC using portable SONY ICF SW07 receiver operating on bateries. Receiver has been utilised outdoors to evade noise from building interference. As antenna only 1 meter telescopic internal antenna was used. Please note that in the recordings two short parts have been removed because of strong noise which covered these parts of station's signal (the noise has been generated by a bulb from a street lamp).

Radio WMLK broadcasting in English on the shortwave frequency of 15150 kHz. Recording made in Europe July 5, 2023 at 0416 UTC using portable SONY ICF SW7600G receiver operating on bateries. As antenna only 2 meters of wire was used put on a tree outdoors.

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.
