Here are two more episodes from my collection of recordings of Shortwave Listener's Digest from Radio Canada International, this time from August 22, 1982 and September 04, 1982.

Vintage AM Radio Airchecks from 1973

Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

Ever wonder what it would be like to time travel? Well, just sit back and relax in your favourite armchair, put on the headphones and enjoy the short six and a half minute trip back to 1973. Here is a collection of 23 AM broadcast band radio airchecks / ID's from 23 U.S. states as recorded at Ancaster, Ontario, Canada. Equipment used was a Realistic DX150A hooked up to a long wire antenna. Please bear in mind these recordings were made using an open mike placed in front of the speaker. For example, WTMJ Milwaukee makes an NBC colour TV announcement (blooper) and you will hear a voice in the background ask "how can that be"?

DATE OF RECORDING: December 08, 1991




RECEIVER AND ANTENNA: Unidentified boombox


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.

Time signal station VNG Lyndhurst (Victoria, Australia): December 13, 1971

Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

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.

RTÉ Longwave End of Broadcasting: April 14, 2023

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.
