Radio Waves: Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

The fascinating story of the first overseas broadcasts BNR (Radio Bulgaria)

In 1936 BNR, then under the name of Radio Sofia, started broadcasting on short waves via the ELZA transmitter (the abbreviation coming from the radio station’s international code – L-Z-A). The same year the radio started broadcasts to abroad.

In 1936, information about Bulgaria could only be heard in Bulgarian and in the artificially created language Esperanto. It was after 1 May 1937, when programs began to be broadcast in French, German, English and Italian.

In the spring of 1938, broadcasts for foreign audiences were further developed to include “Special Broadcasts for Some European Countries”.

What was special about these was the advance publicity which the radio made in the countries for which the broadcast is intended. Such publicity was carried out through the legations, business representatives, foreign radio stations and newspapers so as to attract the attention of listeners abroad in advance.

Authors and hosts of the first broadcasts abroad were free-lance collaborators, among whom were legendary Bulgarian journalists and intellectuals like Petar Ouvaliev, Georges Milchev, Bory Ganchev, Mikhail Hadzhimishev and others.

After 9 September 1944, when the communist regime seized power in Bulgaria, Radio Sofia’s foreign language broadcasts continued to air news bulletins and commentaries on events in Bulgaria and around the world. From 1945 to 1950, Bulgarian Radio Sofia broadcast 10-minute news bulletins in Romanian, Serbo-Croatian, Macedonian, Greek and Turkish.

The Bulgarian Radio began broadcasting in Turkish language in July 1945. The programme targets the Turkish population in this country as well as listeners from neighbouring Turkey. It was run by Chudomir Petrov, BNR Deputy Director and head of the Foreign Information Department.

There were two 10-minute broadcasts each day. Editor was Boris Pilosoff, who then also led the French-language broadcasts. The first hosts of the program in Turkish were Ulfet Sad?kova, R?za Mollov, Mustafa Bekirov, Sali Baklaciev among others.

The Greek-language emissions started in the first half of 1948. By then, democratic power had already been installed in Greece under US and Western European pressure. The Greek Communist Party’s resistance movement was destroyed and many Greek functionaries found refuge in Bulgaria. Curiously, it was with their help that the Greek editorial board was set up.

Similarly, after the political events in Yugoslavia and Albania in 1948, political immigrants seeking protection from the Bulgarian communist government created broadcasts in Serbo-Croatian and Albanian.

The first editors and speakers of Serbo-Croatian language had their quarters at 10 Danube Street in Sofia. There they prepared and translated the material for the Bulgarian radio broadcasts.

Based on historical accounts collected by Bozhidar Metodiev – founder and curator of the BNR Museum.

How does Ukraine keep intercepting Russian military communications? (NPR)

Russia is regarded as one of the world’s most advanced countries when it comes to anything and everything related to spying, and that includes secretive, high-tech military communications.

For Russian leader Vladimir Putin, a former intelligence officer, this is a particular point of pride. Yet Russia’s reputation has taken a major blow with the often bumbling way the military has handled communications in Ukraine.

Here’s a look at how the Ukrainians have effectively countered the Russians on multiple fronts:

Q. Ukraine keeps publicly releasing what it says are intercepted Russian communications from the battlefield. Wouldn’t Ukraine want to keep this under wraps?

Ukraine feels there are huge public relations benefits in releasing intercepted material that’s either embarrassing to Russia or points to Russian wrongdoing, possibly even atrocities.

Ukraine’s military intelligence recently put out audio on social media, saying that as two Russian military members were speaking, one called for Ukrainian prisoners of war to be killed.

“Keep the most senior among them, and let the rest go forever. Let them go forever, damn it, so that no one will ever see them again, including relatives,” a voice says on the tape. [Continue reading at NPR…]

Hot rocks, smouldering ash: Community radio a vital source of information around Indonesia’s Mount Merapi (Channel News Asia)

YOGYAKARTA, Indonesia: With a soft, soothing voice, Mujianto greeted his listeners before reading out an important update from the volcanologists at Indonesia’s Center for Geological Disaster Research and Technology Development (BPPTKG).

Mount Merapi, located just 4km from Mujianto’s village in Boyolali Regency, Central Java province, continued to show signs of heightened activity, he warned.

Since 2019, the mountain has been hurling glowing hot rocks from deep inside its magma chamber. Occasionally, Merapi erupted, spewing a column of smouldering ash high into the air and blanketing nearby villages in black and grey soot.

“People are advised not to conduct any activity in potentially hazardous areas,” Mujianto, who like many Indonesians goes with one name, told his listeners, concluding his announcement.

A farmer by day and an amateur radio DJ by night, Mujianto and six others at MMC FM have been providing residents of Samiran village with information about the dangers posed by Merapi, Indonesia’s most active volcano, as well as educating them on disaster mitigation since 2002.

MMC stands for Merapi Merbabu Community, with Merbabu being another volcano north of Merapi. Mujianto’s MMC FM is one of eight community radios run by people living on the slopes of Merapi, which straddles along the border of the Central Java and Yogyakarta provinces. [Continue reading…]

Oldest radio station in Saskatchewan turns 100 (Discover Humboldt)

It is thought to be the fourth oldest radio station in Canada, and it is the oldest radio station in Saskatchewan. This weekend, Moose Jaw’s CHAB is celebrating 100 years on the air.

The story started in 1922 – April 23rd, 1922 when, after many meetings, planning and anticipation, 10-AB began broadcasting. According to Broadcasting-History.com, the Moose Jaw Amateur Radio Association “had planned originally to operate the station, but found they couldn’t afford to run it, so handed it over to the Kiwanis Club. 10-AB was licensed as a non-commercial station at 1200 kHz with 50 watts of power.”

One hundred years later in 2022 the signal at 800 on the AM radio dial booms across the province and into the northern United States with 10,000 watts of power with studios located atop Main Street in Moose Jaw, Saskatchewan, broadcasting through a transmitter located near Pasqua, just southeast of Canada’s “Most Notorious City”.

It was in the fall of 1922 that the Kiwanis Club turned 10-AB back to the re-organized Moose Jaw Radio Association and in 1924 the studio was moved from the old YMCA building to the top floor of the Bellamy Furniture Store, a building which still stands to this day, having been turned into an apartment block on Main Street, downtown.

In 1931 there was another move to new studios at The Grant Hall Hotel, a lovely, historic building that has been completely refurbished.

Financial struggles in 1933 would lead to 10-AB leaving the air on November 11th. The history books tell us that Rudy Vallee “provided the background to the sign-off singing I’m Heading for the Last Round-Up”. It was just a few weeks later when 10-AB returned to the air as CHAB after being issued a commercial broadcasting license by the federal government. Carson Buchanan, the secretary of the Amateur Radio Association, would own the radio station with partners and become the general manager at CHAB.

It was in 1937 that one of the first true radio stars to come out of Moose Jaw would begin his career. Elwood Glover got his start at CHAB, working for $5.00 a week. Glover would later move on to become CBC Radio’s Chief Announcer.

In fact, CHAB was an affiliate of the CBC from 1933 through 1962 when CBC’s Dominion Network folded and they became an independent station. [Continue reading…]

Matt’s 2022 Rooftop Receiver Shootout!

Many thanks to SWLing Post contributor, Matt Blaze, for the following guest post:

2022 rooftop receiver shootout

by Matt Blaze

I realized it’s been long past time for me to do another head-to-head receiver comparison “shootout”, where you can compare the audio from multiple radios receiving the same signal at the same time. Long time readers of Thomas’ blog may remember I’ve posted a few of these before.

So I took advantage of the nice weather and brought a bunch of radios, recording gear, and an antenna up to the roof to listen and record signals under an open sky. My neighbors, no doubt, wondered what I must have been up to. (Don’t tell them I’m just a harmless radio nerd.)

This year, our focus is on eight “dream receivers” from the 1980’s to the present. Each radio is at or near the top of the line in its class at the time of its release. Our radios include, in roughly reverse chronological order:

Icom R-8600, a current production “DC to Daylight” (or up to 3 GHz, at least) general coverage communications receiver, with highly regarded shortwave performance.
AOR AR-ONE, another DC to Daylight general coverage radio, less well known due to the high price and limited US availability. Excellent performer, but a terrible (menu-driven) user interface for shortwave, in my opinion.
Reuter RDR Pocket, a very cute, if virtually impossible to get in the US, small production, high performance SDR-based shortwave portable receiver. It’s got an excellent spectrum display and packs a lot of performance into a surprisingly small package.
AOR 7030Plus, an extremely well regarded shortwave receiver from the late 90’s; designed in the UK. It’s got a quirky menu-driven user interface but is a lot of fun to use.
Drake R8B, the last of the much-beloved Drake receivers. Probably the chief competitor to the 7030.
Drake R7A, an excellent analog communications receiver (but with a digital VFO) from the early 80’s. It still outperforms even many current radios.
Sony ICF-6800W, a top of the line “boom box” style consumer receiver from the early 80’s. Great radio, but hard to use on SSB.
Panasonic RF-4900, the main competition for the Sony. Boat-anchor form factor, but runs on batteries. Excellent performer, but also hard to use on SSB.

The radios were fed from my portable Wellbrook FLX-1530 antenna, using a Stridsberg Engineering HF distribution amplifier. So every radio was getting pretty close to exactly the same signal at its RF input.

Recordings were taken from the line output, if one was available, or the external speaker/headphone output otherwise. In either case, the audio was then isolated and converted to a balanced signal for recording.

For each signal, I recorded monaural “solo” tracks for each radio, as well as a narrated stereo track in which I compared the audio from each radio (one after the other) against the Icom R8600, with the audio from the R8600 on the left channel and the audio from the other radios on the right channel. This gives you a quick overview of what all the radios sound like.

The stereo recording requires some explanation. For it to make any sense, you MUST listen in stereo, using decent headphones if at all possible. You can switch earpieces back and forth (with your finger on pause and rewind) to get a quick idea of what each radio sounds like compared with a modern receiver, and how they handle things like fades and static.

The solo tracks, on the other hand, consist entirely of the continuous audio from a single radio, with no narration or interruption.

I recorded three different signals, for a three part comparison. (Parts four and up will come, hopefully, soon). I think both the differences and similarities will surprise you.

Part One

Our first signal was the BBC on 9915 KHz, broadcasting from Madagascar to western Africa. This signal was extremely marginal here, intended to show how each receiver can or can’t handle signals down in the noise. It’s definitely not “armchair copy”.

The stereo overview is at:

The individual receiver solo tracks can be found here:

Icom R-8600:

AOR AR-ONE:

Reuter RDR Pocket:

AOR 7030Plus:

Drake R8B:

Drake R7A:

Sony ICF-6800W:

Panasonic RF-4900:

Part Two

Our next signal was the Shannon (Ireland) aviation VOLMET broadcast on 5505 KHz USB. This synthesized voice gives the latest meteorological conditions at airports around Europe. The signal was not strong, but entirely readable. It shows how the radios handle a weak SSB signal. Note that the Sony and Panasonic consumer radios, though equipped with a BFO, were VERY hard to tune properly.

The stereo overview is at:

Receiver solo tracks can be found here:

Icom R-8600:

AOR AR-ONE:

Reuter RDR Pocket:

AOR 7030Plus:

Drake R8B:

Drake R7A:

Sony ICF-6800W:

Panasonic RF-4900:

Part Three

Our final signal was a stronger, though occasionally fading, shortwave broadcaster, Radio Romania International on 13650 KHz AM. This gives you a sense of how the receivers performed on a typical “average” signal that you might actually want to enjoy listening to. Because the radios have different filters and other capabilities, I tuned each radio to whatever sounded best; I did not attempt to use comparable settings (since no common settings existed).

The stereo overview can be found at:

And the individual solo tracks are here:

Icom R-8600:

AOR AR-ONE:

Reuter RDR Pocket:

AOR 7030Plus:

Drake R8B:

Drake R7A:

Sony ICF-6800W:

Panasonic RF-4900:

Subsequent comparisons, hopefully soon, will focus on receiver performance on signals in crowded bands and under various kinds of interference and noise.

A quick note on production: The recordings were made with a 12 channel Sound Devices 833 recorder with a Sound Devices SL-16 mixing console. The audio was isolated and converted to balanced output with Switchcraft 318 direct interface boxes (highly recommended for recording radios with pro audio gear).

The stereo track narration was done by me in real time, as the signals were being recorded. I made some comments about which receivers I thought sounded best that were not always the same as what I would later conclude after carefully listening to the solo tracks once back inside. But judge for yourself. I used a Coles “lip” microphone, an amazing ribbon mic designed decades ago for the BBC for use in highly noisy environments. It was very effective in reducing the sometimes considerable street noise and other ambient outdoor sounds.

Thanks for listening and 73!

Many thanks to SWLing Post contributor, Wlodek, who writes:

I just saw the news [below] that the antennas of the transmitter that broadcast Russian propaganda Vesti FM and Radio Russia on 1413 kHz, 999 kHz and 621 kHz were destroyed.

Ministry of the Interior of the Pridnestrovan Moldovan Republic

April 26, 2022

In the early morning of April 26, two explosions thundered in the village of Mayak, Grigoriopol district: the first at 6:40, the second at 7:05.

Law enforcement officers and emergency services of Pridnestrovie were immediately sent to the scene. Grigoriopol militiamen cordoned off the territory of the Mayak radio and television center, sappers of the Ministry of Defense began to examine all the objects of the PRTC.

As of 9 am, it is known that the two most powerful antennas were out of order: one – megawatt, the second – half-megawatt. Both rebroadcast RF radio.

None of the PRTC employees and local residents were injured.

PRTC – Pridnestrovian radio and television center. This is one of 14 radio transmitting centers of the former USSR.

The signal from the PRTC can be relayed to the USA, the Middle East and Latin America. The radio center was built in the late 60s.

World War II Radio Letters: a real-life shortwave story – Part II

World War II Radio Letters: a real-life shortwave story – Part II

By Jock Elliott, KB2GOM

That so many people have been moved by Part I has been heartwarming. Since writing it, there have been further developments. Tecsun Radio Australia asked (and was granted) permission to reproduce the article for Anzac Day (April 25), when all fallen personnel in all wars are remembered in Australia.

In addition, I became aware of two books – World War II Radio Heroes Letters of Compassion and Waves of Hope (thanks, Bill Hemphill!) – that are all about World War II radio letters. We’ll get to those books in just a bit.

But first, I wanted to tell you something you might find surprising: I did not set out to write about how shortwave listeners had reassured my Mom that my Dad was alive during WWII. Not at all. In fact, in my 50 years as a writer, I found the process of how this came to be written, well, a little strange.

The night before, I had drifted off to sleep thinking about a radio and antenna comparison I had been fooling around with during the day (and which I plan to write up in the future). But in the morning – Holy Smokes! – completely out of the blue, my mind was seized by the following thought: Wasn’t it a shortwave listener in New Jersey that first informed my Mom that my Dad was a prisoner of War? (It turned out that wasn’t quite correct.) It’s in a scrapbook in the basement . . . go find it!

Now, I had not thought about those old scrapbooks in at least two decades, maybe more, but I could picture a particular scrapbook in my mind. Rooting around in the basement, I found it, but it didn’t contain anything about my Dad going missing in action or my Mom being informed he was still alive. Maybe I was wrong, I thought.

Back upstairs in my easy chair, the thought would not leave me alone, kept nudging me: Go find it. More digging in the basement produced the right scrapbook with the right information. Reading it, I found tears running down my face at the kindness of strangers.

As I completed writing World War II Radio Letters Part I and sent it off to Thomas, it struck me as curious that, in all my years writing about radio subjects, I had ever seen an article, or even a mention, of the shortwave monitors of WWII. I thought perhaps no one had ever written on the subject, but I was wrong.

I was poking around the internet and came across World War II Radio Heroes: Letters of Compassion Second Edition by Lisa Spahr. It is a 212-page 10-inch by 7-inch book that details her discovery of her grandfather’s WWII trunk, which contained dozens of letters and postcards from shortwave listeners who wrote to Spahr’s great-grandmother to let her know that her son had been captured and was a prisoner of war.

The book, which contains photos of the original correspondence from the SWLs, chronicles her attempt to contact those shortwave listeners or their families, her discovery of the Short Wave Amateur Monitors Club – which turned the monitoring for POWs names into an organized effort – and a lot else besides. If you enjoyed my first post on this subject, I am pretty sure you will enjoy this book.

The other book – Waves of Hope by Ronald Edward Negra – is about how his mother, Agnes Joan Negra, was a shortwave monitor during WWII who sent out more than 300 letters and postcards to families to inform them that their loved ones were captured and still alive. This is a larger format book (8.5 inches by 11 inches) running to 124 pages that reproduces the letters that Agnes received back from grateful families after receiving the news from Agnes. At the time of this writing, Agnes is still alive, about to celebrate her 102nd birthday!

I found Waves of Hope to be a moving and compassionate book, and I think any SWL will appreciate having it on his or her bookshelf.

Finally, you will find a great deal of additional information here: https://www.ontheshortwaves.com/history-III.html#POW

At the end of it all – the strange process of writing the story, the response of the readers, the books telling the story of WWII radio letters – I come back to the place I started as a grade school boy. It was then that I discovered monitoring the radio can be an almost magical activity . . . and you never know when something you heard may touch another’s life in a profound way.

So keep listening!

Radio Waves: Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

In border radio’s early days, psychics and mystics ruled the airwaves (Mexico News Daily)

Charlatans originally built powerful ‘border blaster’ stations to evade scrutiny by US authorities

In radio’s early decades, among the oddball attractions found on the airwaves from 1920 to 1940 included a husband-and-wife team of psychics broadcasting from the U.S.-Mexico border under the stage names of Koran and Rose Dawn who became so popular that their extensive following helped them create a secondary income source: an organization called The Mayan Order.

Those who applied for membership and received its periodicals, the founders suggested, could harness the ancient Mesoamerican civilization’s secrets.

The pair were just two of the many psychics and other broadcasters of questionable integrity on the airwaves along the Rio Grande during radio’s beginnings. These characters built “border-blaster” stations of such epic size and scope that they could transmit from the Mexican side of the border into the United States.

Author John Benedict Buescher’s new book, Radio Psychics: Mind Reading and Fortune Telling in American Broadcasting, 1920–1940, unearths Koran and Rose Dawn’s forgotten story, as well as those of about 25 other border-blaster radio personalities on the Rio Grande who were heirs to a longtime American fascination with the occult.

“I was surprised how really dominant this stuff was in the early days of radio,” Buescher said. “Radio historians typically have just waved it off, not really focused on it, didn’t really take it seriously.” [Continue reading…]

Why Well-Dressed Towers May Wear Flared Skirts (Radio World)

Cox, Dawson explore the benefits of umbrella-spoke feed for MW towers

Ben Dawson and Bobby Cox will talk about flared skirts at the NAB Show.

“A flared skirt is a set of symmetrically spaced cables around the tower, which attach electrically near the top of the tower, extend outward from the tower along a path similar to the top guy cables, and then turn back in toward the tower base at a point roughly halfway down the tower,” said Cox, senior staff engineer at Kintronic Labs.

“Insulators at this midpoint insulate the cables from ground. The cables terminate on an insulated feed ring encircling the tower base above ground level, similarly to a conventional skirt feed. The antenna is driven between this feed ring and RF ground. The resulting flared skirt takes the shape of a diamond, looking rather like umbrella spokes.”

These systems are used to provide a feed arrangement for grounded towers that is mechanically simple but has certain attractive aspects.

“The wide bandwidth characteristics of the flared skirt make these antenna designs extremely useful for multiplexing several AM stations onto a common antenna,” said Dawson, consultant engineer at Hatfield & Dawson. [Continue reading…]

Palau restores AM radio service (RNZ)

After erecting a new tower Palau’s state broadcaster has restored its AM radio service.

The previous AM tower was destroyed during Typhoon Bopha, in 2012.

Rondy Ronny, head of programming said that the new AM tower and radio service will benefit all the 16 states of Palau.

“A lot of the outlying states are not able to connect into the internet and just don’t have that capability or have very high tech phones like how we do here in Koror. People don’t expect people from Angaur, from Babeldaob to be on their phones all the time.”

Ronny said that the new tower will be crucial to Palauans during natural disasters. [Continue reading at RNZ…]
