ABC Melbourne (3AR & 3LO) Closedowns: Circa 1950s & November 23, 1978

Many thanks to SRAA contributor, Sarah Boucher, who shares the following recordings of two ABC Melbourne radio closedowns, captured via the ABC's domestic inland shortwave relays:

Recording 1

Broadcaster: 3AR Melbourne (ABC)

Date of recording: Circa 1950s

Shortwave relay: VLH-9 on 9.68 MHz (30.99 metres)

Notes: This is a 3AR Melbourne closedown announcement, relayed on shortwave via VLH-9 (9.68 MHz) as part of what the announcer describes as the ABC's "Northern Australian Service." During the sign-off, 3AR identifies itself as also transmitting through the regional stations 2CO Riverina, 3GI Gippsland, and 3WV Western Victoria, alongside the VLH-9 shortwave relay. The announcer then previews the following morning's shortwave frequencies: VLR-6 (6.15 MHz), VLH-11 (11.88 MHz), and VLG-15 (15.21 MHz).

The real highlight is the use of the ABC's network chimes (or "gongs") immediately before the sign-off — a once-familiar feature of ABC presentation that is rarely preserved in surviving recordings. The recording concludes with the national anthem (God Save the Queen) and a formal station closedown.

Recording 2

Broadcaster: 3LO Melbourne (ABC)

Date of recording: 23 November 1978

Shortwave relay: VLR-6 on 6.15 MHz (48.78 metres)

Mode: AM

Notes: This 3LO Melbourne closedown, relayed on shortwave via VLR-6 (6.15 MHz), is historically significant because it captures the night of Australia's nationwide AM frequency realignment to the new 9 kHz channel spacing plan, on 23 November 1978. The announcer — identified as Don Smire — advises listeners of the frequency changes taking effect that day:

Station Old frequency New frequency

3LO 770 kHz 774 kHz

3AR 620 kHz 621 kHz

3WV 590 kHz 594 kHz

3GI 830 kHz 828 kHz

The announcement also notes that the shortwave relay VLR-6 on 6.15 MHz is closing down with the network. Unlike the earlier recording, this closedown ends with Advance Australia Fair rather than God Save the Queen — reflecting the gradual transition in Australian broadcasting practice through the 1970s.

3LO Melbourne (ABC) closedown: 23 November 1978

A little background: what were VLH-9 and VLR-6?

These callsigns belonged to the ABC's domestic inland shortwave network. Before satellite distribution and widespread FM coverage, the ABC used shortwave transmitters to relay its state radio services to remote parts of Australia. Victoria's network used the VLR, VLH, and VLG callsign families to rebroadcast Melbourne programming for listeners in rural and remote areas. Contemporary shortwave enthusiasts often refer to these collectively as the ABC's "Inland Shortwave Services."

A note to readers

Very little context came with these recordings, so the details above have been pieced together from the announcements themselves and what we know of ABC history. If you can add any further detail — or spot something that needs correcting — please leave a comment below. Corrections and recollections are very welcome.

Radio Sofia, Bulgaria: Circa 1984-1985

Many thanks to SRAA contributor Bruce MacDonald, who shares the following recording and notes:

Broadcaster: Radio Sofia, Bulgaria

Date of recording: Unknown

Starting time: Unknown

Frequency: not recorded

Recorded in Hounslow, west London

Receiver and antenna: Sony portable stereo radio cassette player

Notes: A snippet from an old-school DX programme from the English service of Radio Sofia, Bulgaria. This comprises mainly listening tips for rare stations as heard in Europe. Some mention made of the time of year and solar cycle conditions as Solar Cycle 21 was drawing down to minimum, and the need for a good antenna.

I was a teenager when I made this recording, still new to the geeky hobby of shortwave listening, so I didn't log the time, frequency or date of the recording. I recorded this on a Sony radio-cassette player which had a shortwave band on the radio and had yet to save up for a Sony ICF-SW7600D.

Many thanks to SRAA contributor, Andy Wang, who shares the following recording and notes:

Broadcaster: BBC4

Date of recording: June 26, 2026

Starting time: 19:58UTC

Frequency: 0.198MHz

Your location: Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands

Your receiver and antenna: "Mini-Whip" antenna in AM mode with 9.09 kHz RF filtering

Mode: AM

Safe for children?: Yes

Notes: BBC4 on longwave 198KHz was shutdown on 27 June 2026 at 00:00 UTC.

After the shutdown, the station is repeatedly playing the migration guide for the listeners.

I guess there are still some old electric meters that haven't been replaced, they rely on the longwave signal...

The noise in the recording is probably caused by lightning, the receiving time is in summer.

BBC Radio 4: "The Sound of Soft Power" (May 23, 2026)

Many thanks to SRAA contributor Andrew, who shares the following recording from Radio 4.

“I chose to record the programme on one of my old radios received on the soon-to-be-discontinued Droitwich 198kHz transmitter.

The radio is a Pye Mistral (picture attached) which was (almost) the first radio that I even had around 1972. It might even be tuned to the right place on the dial ("Radio 2", 1500m). That was the station that was broadcast on that wavelength back then.

It is not a well-performing radio, but it has a wide-ish audio bandwidth and the recording is probably as nice-sounding as it can be on LW - that warm AM sound that you refer to in the programme. Reception was on the radio's internal ferrite rod aerial in one of the rooms of the house here on the South Coast of the UK.”

This recording captures a special edition of BBC Radio 4’s The Sound of Soft Power, a documentary exploring the cultural, political, and emotional legacy of international broadcasting and shortwave radio. The programme weaves together archival recordings, listener memories, and contemporary reflections on a medium that once connected the world across borders and ideologies.

The documentary also makes extensive use of recordings preserved in the Shortwave Radio Audio Archive, highlighting the importance of preserving off-air recordings as historical documents. In addition, SRAA curator Thomas Witherspoon is interviewed during the programme, discussing both the archive itself and the enduring fascination many listeners still have with shortwave broadcasting.

While this is not an off-air shortwave recording in the traditional sense, it is very much connected to the history and culture of shortwave listening. Andrew’s decision to record the programme from BBC Radio 4 Longwave using a vintage Pye Mistral receiver adds another layer of radio history to the experience — capturing the broadcast with the characteristic warmth and ambience of longwave AM reception just as the Droitwich 198 kHz transmitter approaches the end of its service life.

For those interested in radio history, international broadcasting, and the sounds of the shortwave era, this programme is well worth hearing.

This recording is being published on 27 June 2026 to mark the closure of the BBC Radio 4 Long Wave service from Droitwich on 198 kHz, bringing to a close one of the United Kingdom’s longest-running and most historically significant AM broadcast transmissions.

BBC Midwinter Broadcast to Antarctica: June 21, 2026

This is the BBC Midwinter Broadcast to Antarctica recorded on June 21, 2026 at 09:30 UTC in Foulden, Scotland, UK. The radio was an Elecraft KX2 connected to a 31-foot 9:1 random wire antenna in the back garden. The broadcast starts on 9460 kHz, but I then move to 12070 kHz because it had slightly less local noise.

Thomas Witherspoon

Personal note

The BBC Midwinter Broadcast remains one of my favorite SWLing events of the year. I simply love the idea that the BBC would broadcast from two different sites on three different frequencies via shortwave to a relatively small audience of British Antarctic Survey scientists wintering over in Antarctica.

It's always a joy to listen live, knowing that they're celebrating midwinter with parties at their stations and hearing the voices, messages, laughter, and well-wishes of loved ones carried to them over the air by shortwave radio.

In an age of instant communications, there's still something magical about that.

Xing Xing Guangbo Diantai (Star Star Broadcasting Station): March 16, 2026

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

Broadcaster: Xing Xing Guangbo Diantai (Star Star Broadcasting Station)

Date of recording: March 16, 2026

Starting time: 2358

Frequency: 19.052

Your location: Thailand

Your receiver and antenna: Kiwi SDR with Wellbrook loop

Mode: Single Side Band

Safe for children?: Yes

Notes: This is a "numbers station" broadcasting in Mandarin Chinese, presumably sending encrypted messages to Taiwanese intelligence agents in mainland China, from Taiwan. It appears to follow a set daily schedule, and begins each transmission with the tune of a Chinese folk song played on a flute. This is followed by station ID, given twice, and a few announcements in Mandarin, then a sequence of numbers read in groups of four. An excellent article about this station can be found on the Mount Evelyn DX Report written by Rob Wagner VK3BVW in May 2025.

Starting time: 2130 UTC

Frequency: 9.625 MHz

Reception location: Ancaster, Ontario, Canada

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

Mode: AM

Notes: The Israel Broadcasting Authority used to broadcast in various languages on shortwave in the early 1970's. Their English language transmission to Europe could often be heard well here in southern Ontario, Canada between 2045 and 2130 hours UTC on 9625 kHz. Here is a recording made circa 1971 as they concluded their program in English and switched to French at 2130 hours UTC.

Mode: AM

Notes: Here's a recording pulled from my radio archive of Radio Nacional da Amazonia from Brazil on the shortwave frequency on 11.780 MHz from July 16th, 2025. What's interesting is that this was recorded on a weekday, and usually, back-to-back music is not heard on weekday evening programming. Along with the announcers who are usually high energy are not in this recording. Around 20 minutes in, I stopped recording and resumed recording at 01:05 UTC until the end of the recording.

V32 Persian/Farsi Numbers Station: March 16, 2026

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

On March 16, I listened to V32 using the SV1BTL SDR in Athens, Greece. The voice came on at exactly 1800 UTC, but right up to 1759, the bubble jammer was being heard on that frequency. There did not appear to be any jamming during the actual "broadcast". The signal was very strong, averaging 20 dB over 9. At 1823 UTC, there were 12 users listening on this particular SDR, and 8 of them were tuned to 8742 kHz!

V32 Persian/Farsi Numbers Station: March 13, 2026

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

Broadcaster: V32 Persian/Farsi numbers station

Date of recording: March 13, 2026

Starting time: 0226 UTC

Frequency: 7.842 MHz

Receiver location: Israel

Receiver and antenna: Kiwi SDR with MLA-30+ Active antenna

Mode: Single Side Band

Notes: Background material obtained via Radio Free Europe / Radio Liberty.
This radio signal first started broadcasting on February 28, about 12 hours after the United States and Israel began bombing Iran.

A man's voice can be heard speaking Persian, counting out a series of apparently random numbers. The numbers are read out for varying stretches of time, followed by a pause in which the word tavajjoh -- which translates as "attention" -- is spoken three times. (around the 48 second mark in the attached recording)

Beginning on March 4, the signal started to be jammed, with a cacophonous screech of electronic noise that made it all but impossible to hear the numbers. The original transmission paused for a period of time, then moved to another shortwave frequency.

The transmission, that has been dubbed V32 by at least one group, is called a numbers station, a Cold War-era tool that employs radio transmissions and old-school cryptology to transmit secret messages, usually to spies around the world. It's location is suspected to be somewhere in central Europe.

The attached recording of V32 was made on March 13, 2026 around 0230 hours UTC on 7842 kHz upper sideband USB using a Kiwi SDR located in Israel. I began the recording on 7841.9 kHz, but switched after a few minutes to 7842 kHz. This will account for the change in voice pitch.

Also attached is a brief recording of the jamming signal, or “bubble jammer”, made on March 6, 2026 on 7910 kHz (V32’s original frequency) at 0218 UTC.

Polish Radio External Service (Via WRN and WRMI): September 26, 2025

Many thanks to SRAA contributor Liam Spencer, who shares the following recording and notes:

Broadcaster: Polish Radio External Service (Via WRN and WRMI)

Date of recording: September 26, 2025

Starting time: 02:59 UTC

Frequency: 9.455 MHz

Reception location: Berthoud, Colorado, USA

Receiver and antenna: Sihuadon D-808 with telescopic antenna

Notes: After the withdrawal of most Overcomer Ministry broadcasts in the Summer of 2025. WRMI began relaying the World Radio Network North American stream to fill the empty hours. While this is great for many shortwave listeners, as we get to hear stations that used to broadcast on shortwave again. WRMI isn't making any money from broadcasting the World Radio Network, and it is unknown how long these will last. On September 26th, I recorded the Polish Radio External Service, as they became part of my daily listening thanks to WRMI. I used a cassette tape to record the broadcast. Sometime during the recording, a few seconds of the broadcast were cut as I had to flip over the tape to continue recording.
