Today is the 80th anniversary of a well known Shortwave broadcaster: The Voice of Vietnam.
My 1980s QSL for the Voice of Vietnam
The Voice of Vietnam started broadcasting on September 7th, 1945 from Hanoi in what was then called the Democratic Republic of Vietnam. The station was established shortly after the August Revolution of 1945 at the end of World War II. The communist-led Việt Minh sought indepence and defeated the French in 1954.
The Voice of Vietnam was one of my first real DX QSLs when I started the hobby in 1979. I received a reply in 3 months. The 10040 kHz they were broadcasting on just outside the formal 31m band made that they suffered less from interference. With the formal QSL leaflet came a more friendly postcard.

In yesterday’s English broadcast the Voice of the Vietnam spent some time on military parades celebrating the August Revolution. But there was also a special topic on the history of the Voice of Vietnam:
I like chasing DX stations. But I also like listening to producers that offer something special on shortwave. For that reason I regularly check the Channel 292 calendar. But Shortwaveradio.de also offers nice programs.
This weekend I listened to SURF, a program from Imaginary Stations via Shortwave Gold. My report was confirmed by DJ Frederic Moe with a nice eQSL:
Imaginary Stations is a shortwave radio program producing creative broadcasts with themed music and content. One of these is around surf classics (SURF series). Another theme is analog music archives (The Ancient Analogue Archive). They are on air via Shortwave Gold (Shortwaveradio.de) and WRMI. In the program I listened to they invited people to become member of their Pen Pal club, and the Japanese “Surf” music played was by recommendation of a member from Tokyo.
You can find more info about Imaginary Stations on this Factsheet:
By the way, the Facebook page of Imaginary Stations and Radio Skybird features Shivering Sands Army Forts in the Thames, from which Radio City was broadcasting. A place full of radio history as I explained in an earlier post.
The Moosbrunn shortwave antenna is no more since January this year. Fortunately I was able to get a confirmation of my reception of ORF Radio Ö1 broadcasting via Moosbrunn. It is sad to see the destruction of the Moosbrunn facilities just after the celebration of 100 years radio in Austria. CARO, the Club Amateur Radio ORF, aired a special centennial broadcast on 6055 kHz in October 2024. It took a while (no problem, after all it is all volunteers work), but this week I received the beautiful eQSL.

I listened to a rebroadcast of an interview with Prof. Harranth who was the curator of the Dokumentationsarchiv „Funk“ (Radio) with 6 million items about Austrian radio history.
CARO sent the following accompanying message with the QSL:
The ORF Amateur Radio Club (a division of the ORF Sports Association, known as CARO) organized a series of broadcasts following the announcement of the demolition and decommissioning of the large shortwave transmitting station in Moosbrunn. These broadcasts paid tribute to the station’s decades-long successful operation. Some of these audio programs can be replayed via CARO’s website: https://www.oe1xrw.radio
Additionally, the website offers a comprehensive documentation of the former station’s history for those wishing to read or view more about it.
For many years, Moosbrunn stood as a symbol of Austria’s positive global image and the voice of its people. The station housed a dedicated shortwave editorial team — first under Radio Österreich International (ROI), later under a modified retransmission of standard ORF radio content.
Among the broadcasts were several historical retrospectives, including a program commemorating 100 years of radio in Austria. A particularly notable feature was an unpublished interview with the late Prof. Wolf Harranth, who passed away in 2021. In it, Harranth candidly explained the political, social, and technical background of the founding of ORF’s predecessor, Radioverkehrs AG (RAVAG).
Following the final transmission by Radio Dessau on 31 December 2024, deconstruction of the Moosbrunn site began in early 2025. First to be brought down was the globally unique, 70-meter-high and equally wide rotatable curtain array antenna, followed by other remaining structures like the log-periodic antenna and the “Reusenantenne”. The transmitter building was cleared. Discussions are underway regarding future use of the property, including possible 5G technology experiments.
In total, nearly 1,000 reception reports were received across the two final broadcasts (October and December 2024), including several hundred written and email confirmations. Because it was initially unclear whether the site might be preserved, the sending of QSL confirmations was delayed. Eventually, a dedicated CARO QSL team was formed, with Wolfgang OE3OBB managing electronic confirmations.
CARO sincerely thanks everyone for their confirmation reports and long-standing loyalty to the Moosbrunn transmitter — many of which spanned several decades.
We wish you good health and continued success. Club Amateur Radio ORF, Vienna
Not my first QSL of this station. I received one earlier in 2023. But there is no harm in sending an additional report to a station that keeps a tradition alive. I heard them during the Easter weekend. As last time the QSL was part of a lengthy PDF with lots of history… I sent my report to wmrscotland@mail.com and got a reply after 16 weeks. Hey, it’s a hobby after all, so things can take a bit of time.
A hand drawn QSL used in 1981. That’s when I ran my own Radio Arcadia pirate station and for a teenager the costs of printing a QSL card was quite something.
Like last year the German service of Radio Taiwan International ran a few test transmissions to find the best frequencies for their summer broadcasts from Tamsui. My reception report to deutsch@rti.org.tw was awarded with a beautiful QSL that arrived 6 weeks later by mail.

Every year the BBC has a short program with family greetings to the staff of the British Antartic Survey. This year the program was aired for the 70th time. It’s a bit of a tradition as unlike 70 years ago the researchers have access to broadband internet enabling them to communicate with friends and family in the UK.
I heard them on 12065 kHz from Woofferton and on 9575 kHz from Ascension Island. A program with family greetings from the UK to the folks at South Georgia and Rothera Base. And with a brief message from King Charles as well. In the 90-ies I as able to receive these BAS stations on 9106 kHz, but I’m not sure whether they are still active on that frequency given modern communication tools.
Below the opening clip taken from the Woofferton broadcast as it was of better quality. The Ascension broadcast had a strange digital signal over it which almost seemed to originate from the station itself.
I sent a report to their eQSL service. Unfortunately it only returns random picture postcards without reception details. But fortunately mine was with a picture of Ascension Island facilities.

Last night I made my first reception of a SSTV station from Brazil. I picked up pictures from PY4XC, Rio Doce, Minas Gerais, about 200 kms north of Rio de Janeiro.
When I checked QRZ.com it was obvious that the picture received was that of the shack:
Shortwave Radio from Winsen is an easy catch here. For a little compensation they will confirm your report with a traditional QSL card. You can read the details on their website.

The station is located in Winsen “on the river Aller”. So that is the Winsen located 20 km north of Hannover, Germany (there is another Winsen south of Hamburg). They broadcast on 6160 and 3975 kHz. Next to their own program Shortwave Gold there are various other program producers that use the Shortwave Radio facilities.
I received a SSTV station with call sign UT1KWA from the Ukraine on 14230 kHz. It turned out to be the Rivne DX club, from Rivne, a city in the northwest of the Ukraine.
Pavlo (UT1KY) is running the station. He is a teacher by profession, but also teaches kids to how to run radio. A very nice initiative as I welcome anything that interests kids in technology! QSL manager for the station is Antonello IK2DUW.
Pavlo also shared some nice pictures of him and kids working at the club, showing some nice awards they got. Given privacy considerations I prefer to share a picture they posted on their website. I think this is Pavlo some years ago. His beard is a bit more grey today (as is my own hair).
The Rivne DX club
Thank you Pavlo for your kind reply, all the best with your initiative and the Rivne DX club. It’s these sort of connects that make our hobby so nice.
Since I resumed the hobby I spent quite a bit of time on maritime DX (DSC mode) and NDBs. But I didn’t do as much on HF Aero. So time to see what’s going on the aero-bands. I did already a couple of SelCal decodes (so nice that we have programs like MultiPSK that allow us to do so) when I discovered HFDL.
I first heard Shannon. On audio the pattern is a brief tone, and then a data burst, as in this audio clip. Using the Klingenfuss guide I started to look for other frequencies, decoded with MutliPSK, and got some Auckland decodes.
Receiving something from New Zealand is always nice, but what about a QSL? I decided to contact Airways New Zealand. Todd, who is operations team lead at Airways told me that they were truly interested in my reception, it wasn’t Auckland Radio that I heard (as they are responsible for voice), but he could confirm I received the HF data link from Auckland.
Meanwhile I’ve learned a little bit more about HFDL. Apparently it is a service called ACARS (Aircraft Communications and Reporting System) initially developed by ARINC (Aeronautical Radio Incorporated). ARINC is now part of Collins Aerospace. UDXF offers a nice information sheet about this service that allows aircraft to exchange date via a ground station with their operators.
Apparently there are 16 ground stations that provide HFDL. I’ve heard Hat Yai, Telde (Canarias), Shannon and Auckland by now. The beauty is that via this digital technique aircraft can for example broadcast their position in 2 seconds, something which would take 1 minute by voice. And during high solar activity periods the digital mode of communication proved to be much more reliable for aircraft flying over polar regions in particular.
