Radio Nacional de Venezuela: October 11, 2004


Many thanks to SRAA contributor, Dan Robinson, who shares the following recording and writes:

With the news over the past few years, and especially over the last few weeks, of the rapid decline of Venezuela, it’s interesting to recall that there was a day when that country was a powerhouse on the shortwave band, with numerous private radio stations that SWL’s around the world could hear in the 90, 60, 49, 31, and 19 meter bands.
There was also a brief attempt to put Venezuela on the map as an international broadcaster, with Radio Nacional de Venezuela which was audible at good signal levels.

Our thanks to Dan for this 45 minute recording from 2004 when Radio Nacional de Venezuela was on the air (October 11, 2004 starting around 20:20 UTC):

NIST Radio Station WWVH as it sounded in the 1980s


Many thanks to SRAA contributor, Myke Dodge Weiskopf, who shares the following recording and notes:

NIST Radio Station WWVH as it sounded in the 1980s. To contrast with other recordings of the WWVH station ID, note that announcer Jane Barbe does not say (her now-famous) “Aloha!” at the end of this version.
This recording was found at WWVH in 2015 on an undated cassette labeled “JB on Old Audichron TCG” (which stands for Time Code Generator, the device which reconstructs and plays back Jane’s voice over the air). As such, the precise broadcast year is not known, but it is consistent with the voice and broadcast format of the 1980s, until the introduction of the short-lived digital voice in 1991.
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.

WWV Time Station (15 MHz): November 3, 2017


Many thanks to SRAA contributor, Emilio Ruiz, who shares the following recording of WWV and notes:

Sad for the news, the closing of WWV is like close a park, a comunity place where scientifics and enthusiast of radio could learn and experiment not only about time, radio propagation too. I not have much money for bought radiofrecuency equipment for repair or make my own radios, i use WWV for that. 
To go to the future it is not necessary to destroy the past, I'm teaching to children about science and technology and when talk about radio share with they the listen of WWV with old radio receiver (BC-548Q), for they the sound of ticks and the history about radio and time is a amazing topic.
I wrote this review (in Spanish) about WWV for those SWListeners and Radio Amateurs who do not spoke English,--I think can be useful.
I hope radioamateurs of U.S. can reverse the decision.

Radio Netherlands (Media Network): April 9, 1982


Many thanks to SRAA contributor, Tom Laskowski, who shares the following recording and notes:

Along with RCI's Shortwave Listener's Digest, Radio Netherlands Media Network was another favorite DX program of mine. Here is a recording of an episode from April 9, 1982 which is the first recording of this program from my archive. The show highlights are: media coverage of the Falklands War from the British and Argentinian sides, Pete Meyers with a report that Radio New Zealand did not shut down, the US-Cuban media war, Richard Ginbey with African media news and John Campbell with a clandestine radio report. Audio quality is only fair for this recording. I will try not to post recordings of Media Network which are already available on Jonathan Marks' Media Network Vintage Vault website.

Radio Trans Mundial (final shortwave broadcast and English transcript): August, 08 2018

Radio TRansmundial.jpg

Many thanks to SRAA contributor, Dan Robinson, who shares the following notes about the final transmission of Radio Trans Mundial (RTM).

Dan writes:

FYI — I am monitoring Radio Transmundial via [the PY2BS KiwiSDR in] Brazil. They are in the midst of a final discussion in Portuguese between two announcers, mentioning advances/changes in technology, Internet, etc. that are forcing the station off the air. Many mentions of shortwave.

See attachments…..audio files are of studio discussion in Portuguese about their decision to end SW….then another file going right up until 1900 UTC or thereabouts when they went off.

At about the 9:36 mark in the 1st audio file announcer introduces a technical person (sounded like someone from TWR, but also mentioned was “director of communications”) to begin a discussion about their decision to end shortwave — that discussion lasts until about the 34:30 mark when they go into full IDs.

Second audio file you can hear Zanzibar gradually fading up and dominating the frequency, then in the clear after Transmundial goes off 11,735.

Many thanks to SWLing Post contributor, Fabiano Barufaldi, who kindly volunteered to translate the conversation between the RTM Director of Communication and the Director of Studios and Technical Affairs in this final shortwave broadcast of Radio Trans Mundial (RTM).


Hello Dear Listeners! It’s 2:46pm.

With us are André Castilho, our director of communication and also Samuel Marcos, director of studios and technical affairs, live.

Good morning all. It’s a pleasure to be in front of such important microphones in the history of Brazilian gospel radio.

First of all, I’d like clarify that we’re not the founders of Radio Transmundial, which was founded in 1970 in Brazil, initially transmitting from Bonaire in the Antilles in the Caribbean Sea, covering the entire Brazil’s territory in shortwave and mediumwave, reaching most of South America. They decided to discontinue the shortwave operation in the early 1990’s; they have recently resumed the 440KW power transmission from Bonaire, now with better quality, reaching the Amazon region and even listeners in the southern Brazil in MW 800kHz.

When the Trans World Radio (TWR) shut down its shortwave transmission, the Radio Transmundial (RTM) decided to invest in shortwave in the 1990s acquiring a transmission site in Santa Maria – RS, Southern Brazil, in three shortwave frequencies, covering up to 80% of the Brazilian territory. Recently, the Bonaire site increased the MW transmission power, reaching a greater territory share.

Talking about the 1990’s, a new, powerful transmitter was acquired for the Brazilian Santa Maria site, we always have been praised because of the quality of the transmissions. Our site was built with great diligence and care, mainly by Mr. Walter Wilke, who did excellent work during 20 years of dedication to our shortwave site, with the best equipment and sound, using three shortwave frequencies during these years that are now coming to an end.

That’s sad news, we’re not happy to say that but it’s an important, necessary announcement that the RTM shortwave transmissions are being shut down this midnight. We had ended the 31 meters transmission, now we’re ending the 25 meters, 49 meters also, and we are so sorry about that.

We have been asked by our listeners the reason, and it’s important to notice that this decision wasn’t made yesterday. We’ve been studying this matter since at least an year ago, considering the reach and audience and, of course, the financial aspects of it. The RTM has been keeping the shortwave transmission site and the equipment in excellent codition and, until now, Lord has provided the financial ways to maintain the operation but considering the low audience, the return of Bonaire to shortwave in high power, and elevated power expenses; all those factors contributed to take the decision some time ago of ending the operations – a decision that was matured – and now comes the time that we are finally shutting down the shortwave transmissions.

The summary of our decisions was that the audience was too low so it was not being worth to keep such expensive shortwave structure. To give our listeners a rough idea, when we increased the power (50kW to 25 meters, 10kw to 31 meters and 7.5kW to 49 meters) we had to hire a custom, special grid with the local power company – and that costs!! We are a non-profit organization, funded by voluntary donations, so we need to be very careful with our budget. It’s sad to say that, because we love the radio, but the audience was very low, not being worth expending that amount of money.

We are living a new tech era, so we as a mass media organization must be care about of our own survival, that’s why we took that decision and also because we’re experiencing over the years great increase in audience through the internet and by the local affiliates network as well.

Still talking about costs, our transmission equipment is nearly 20 years old, although it was bought brand new and being well kept by Mr. Wilke, it’s an old equipment that demands expensive maintenance because it’s imported equipment running on valves. To give you listeners and idea, a burnt valve had to be recently replaced and costed nearly 5,300 USD, so that give us an idea of how expensive is to keep that, beside the monthly power costs.

We have brainstormed on how to reach poor, isolated communities (Indian, forest people) with no access to new technologies for example by providing them our content stored in memory cards – we received reports of missionaries, social workers assuring that this is being welcomed. We’re also working to increase partnership with local stations to relay our content.

…[now they list some of the local affiliates currently relaying content throughout the Brazilian territory]…

There is a reason for us to be ending the shortwave transmissions on this particular day (August 8, 2018) – this is because our shortwave broadcasting license is expiring today, so due to the reasons explained above and also because the government’s bureaucracy, we are not going to renew it.

We are sorry for the listeners who have in the radio the only way of getting our content, the DXrs as well, but that’s a cost vs audience matter.

We’re having an average of 50,000 unique listeners over the Internet, some others through local affiliates, so we have to be responsible with our budget and focus on getting return over the investment, providing accountability to the donors.

[… now they explain how to listen over the station website or from the mobile app.. “ask your nephew how to do it LOL :-)” ]

[the host greets them by the detailed explanation on how the broadcast license process works, the costs and bureaucracy]

We thank our listeners for the support, care and understanding. We’ve been passionate shortwave listeners forever and that’s probably the reason why we do this for a living today.

New technologies arise in an incredible speed in these days–getting cheaper too, enabling more people to benefit from them.

Some people understand that in a near future the technologies will be unified and we will end on having a single media device for all content (TV, radio, internet, communications, etc), mostly cheap or even for free.

That will not be a happy day…that’s a sad day instead – we’d like to continue with shortwave broadcasting but we’re getting empathy and understanding from most of our listeners – we’re not stopping, the RTM keeps on going.

Thank you all for understanding and for your care; keep following us over the Internet, we’ll also be broadcasting every hour the list of local affiliates network.

… now they play the station’s identification jingle

… resuming the regular programming…


Thank you, Fabiano, for taking the time to write up this excellent translation. This commentary was insightful and without your help, I would have never been able to understand or appreciate it.

And thank you, Dan, for making and sharing these historic off-air recordings.

Radio Veritas Asia Final Transmission: June 30, 2018

Radio Veritas Asia Adhesiu.jpg

Live, off-air recording of the final transmission of Radio Veritas Asia, broadcasting from Quezon City, Republic of the Philippines. The broadcast, in Filipino (a standardized form of Tagalog), was transmitted on 30 June 2018, beginning just before 15:00 UTC, on the frequency of 11675 kHz using a 250-kW transmitter at Palauig in the Province of Zambales, north-east of Quezon City. The transmission had an antenna beam direction of 300° and was directed to Filipinos living in the Middle East.   

The broadcast was 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 total bandwidth RF filtering. Reception of the broadcast was fair with some noise.

Radio Guinée: May 30, 2018


Live, off-air, approximately one-and-a-half-hour recording of Radio Guinée, an outlet of the government broadcaster Radio Télévision Guinéenne, broadcasting from Conakry, Guinea, on 30 May 2018 beginning at about 17:34 UTC. The broadcast was on a shortwave frequency of 9650 kHz using a transmitter at Sonfonia, a suburb of Conakry, with a reported power of 50 kW and with an omnidirectional antenna.

The transmission was received on a Tecsun PL-880 receiver with a Tecsun AN-03L 7-metre wire antenna in Meloneras, Gran Canaria, Canary Islands, in AM mode with 5 kHz RF filtering. Reception was quite good initially although interference from what is believed to be Saudi Arabian jamming (siren style) directed against an Iranian broadcast in Arabic earlier on the same frequency can be faintly heard. The jamming signal ends at about 18:26 UTC but adjacent channel interference begins a couple of minutes later and continues at varying levels through to the end of the recording.

The recording starts with a program of indigenous Guinean music in progress. Station identification at 17:58 UTC is followed by a news bulletin and then a sports program discussing mostly football. This was followed by a talk program. The spoken-word programs are primarily in French with some indigenous language segments.

The Radio Guinée shortwave transmission is a relay of the Radio Guinée Conakry FM station on 88.5 MHz.

New Bransfield House, Rothera Research Station, British Antarctic Territory (BAS Photo)

Two live, off-air, half-hour recordings of the BBC World Service special Antarctic Midwinter Broadcast on 21 June 2018 beginning at 21:30 UTC. The broadcast features special messages and music for the staff of the British Antarctic Survey overwintering in Antarctica.

The first recording is of the transmission on a frequency of 7360 kHz from the BBC's Ascension Island relay station (250 kW transmitter power, antenna beam 207 degrees). The transmission was received on a Tecsun PL-880 receiver with a Tecsun AN-03L 7-metre wire antenna in Hanwell (just outside Fredericton), New Brunswick, Canada, in AM mode with 5 kHz RF filtering. Reception was fairly good, albeit a bit noisy and with noticeable transmitter hum.

The second recording is of the transmission on a frequency of 5985 kHz from the BBC's Woofferton, England, transmitting station (250 kW transmitter power, antenna beam 184 degrees). The broadcast was 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. Reception of the broadcast was very good.

The program started slightly late for both transmissions with parts of the first one or two sentences missing. The program actually starts with "This is the BBC World Service in London calling Antarctica. Welcome to the Antarctic Midwinter Broadcast, a special ..."

Voice of Korea: June 13, 2018


Live, off-air recording of the Voice of Korea broadcast in English on 13 June 2018, beginning at 18:00 UTC on 15245 kHz. The broadcast was transmitted from Kujang, Democratic People's Republic of Korea (North Korea), with a transmitter power of 200 kW.
