Tens of thousands of ordinary Russians are joining the resistance
n a bedsit in Vologda, a Russian city 500 miles north of Moscow, a man sat at a desk surrounded by recording equipment. In his early 60s, tall and thin with long grey hair, glasses and a moustache, he looked like an ageing rock star making a new album. His name was Vladimir Rumyantsev. He lived alone, and his day job was as a stoker, tending a furnace in a factory boiler-room. In the evenings he was the dj of his own pirate-radio station, broadcasting anti-war diatribes against Putin’s “special military operation” in Ukraine.
Rumyantsev set up the station before the war as a hobby. Radio Vovan (a play on a nickname for Vladimir) mainly broadcast music from the Soviet era that he found in online archives. He said he needed a break from oppressive state propaganda. “Some kind of ‘patriotic’ hysteria started on the airwaves, and as the sole occupant of the flat I voted unanimously to ban the broadcasting of federal tv and radio channels in my home. Well, I had to create something of my own to replace it,” he wrote to me. [Continue reading. Note that this article may be behind a paywall from your location…]
Jabrallah Tia was a teacher in Sudan in 2011 when a brutal war forced him to flee to a refugee camp in newly established South Sudan. Thirteen years later, Tia is still in a camp but with a new career: journalist.
The Ajuong Thok camp in the Ruweng Administrative Area is home to almost 40,000 refugees and displaced people, most from Sudan. Another influx is expected soon, after a fresh conflict broke out in April.
“It’s terrible now when Sudan has started another war. … We’re expecting more people to come from Sudan, as they’re fleeing the war there,” Tia told VOA in a video interview over Zoom.
He knows what that’s like. Tia had to leave everything behind when he fled his home in South Kordofan state. But he said he has found new meaning in his journalism work. Continue reading →
Having a big bookshelf of ham radio books and magazines used to be a point of bragging right for hams. These days, you are more likely to just browse the internet for information. But you can still have, virtually, that big shelf of old ham books, thanks to the DLARC — the digital library of Amateur Radio and Communications.
A grant from a private foundation has enable the Internet Archive to scan and index a trove of ham radio publications, including the old Callbooks, 73 Magazine, several ham radio group’s newsletters from around the globe, Radio Craft, and manuals from Icom, Kenwood, Yaesu, and others.
There are some old QST magazines and the index to newer ones. You can find catalogs and military documents. We miss a lot of these old magazines and newsletters. For example, RCA’s “Ham Tips” is something you won’t find anything like anymore. Most of the material is in English, but there are some other languages represented. For example, the Dutch version of Popular Electronics is available. There’s also material in Afrikaans, Japanese, German, and Spanish. [Continue reading at Hackaday…]
Ham Radio operators, we’re calling you! Members of the Ham Radio Science Citizen Investigation (HamSCI) will be making radio contacts during the 2023 and 2024 North American eclipses, probing the Earth’s ionosphere. It will be a fun, friendly event with a competitive element—and you’re invited to participate.
Both amateur and professional broadcasters have been sending and receiving radio signals around the Earth for over a century. Such communication is possible due to interactions between our Sun and the ionosphere, the ionized region of the Earth’s atmosphere located roughly 80 to 1000 km overhead. The upcoming eclipses (October 14, 2023, and April 8, 2024) provide unique opportunities to study these interactions. As you and other HamSCI members transmit, receive, and record signals across the radio spectrum during the eclipse, you will create valuable data to test computer models of the ionosphere.
The Canadian pop music station PopShopRadio in British Columbia has just announced that they will use the DRM standard to broadcast their best pop music towards Europe on the 5th March 2023 at 2000-2100 CET (GMT+1) on 5875 kHz (85kW) from Wooferton in the UK.
This radio station is specialised in transmissions of well-known pop music from the 60s and 70s or even before that. They are collecting the best tunes from various countries and offer them to the world using shortwave. This time round they wish to also use the DRM standard in SW to be able to reach distant parts of the globe in much better sound quality.
Radio stations in several Russian cities were disrupted on Feb. 22 by the sound of air raid sirens and a warning of imminent missile strikes.
The broadcasts were reportedly heard in Belgorod, Chelyabinsk, Kazan, Magnitogorsk, Nizhny Novgorod, Novouralsk, Pyatigorsk, Stary Oskol, Syktyvkar, Tyumen, Ufa, and Voronezh, among other cities. Recordings of the broadcast were shared on the social media network Telegram and reported on by Meduza.
Meduza, an independent news agency now based in Latvia, was forced to move its operations out of Russia during the media crackdown that followed Russia’s February 2022 invasion of Ukraine. [Continue reading at Radio World…]
Only 223 stations remain on air 18 months after Taliban regained control of the country
In the 18 months since the Taliban retook full control of Afghanistan, 177 radio stations have gone off the air in the country, displacing about 1,900 journalists and other employees.
In a statement released on World Radio Day 2023, the Afghan Independent Journalists Association noted that during the Islamic Republic period from 2004–2021, there were as many as 401 radio stations operating in Afghanistan. As the Taliban Insurgency increased its control of the country, about 56 stations went off the air before the Taliban took control and reinstated the Islamic Emirate of Afghanistan in August 2021.
Since then, around 120 stations have ceased broadcasting due to economic pressures. The AIJA stated that only 223 stations currently operate in the country.
With these stations going dark, more than 1,900 journalists and media workers are now unemployed in the country, include 1,075 women. [Continue reading at Radio World…]

Radio and Peace: Tim’s Essay for RRI
Many thanks to SWLing Post contributor, Tim Brockett, who writes:
Hello Thomas,
Radio Romania recently requested that listeners submit comments on the topic “Radio and Peace”. Radio Romania selected several submissions and read them on their North American broadcast on February 12, 2023 UTC at 04:50. I was honored to hear that they enjoyed my short essay and read it over the air:
Radio and Peace
Shortwave radio presents a unique opportunity to engage listeners and build pathways for understanding other cultures. Like reading a book, listening to the radio involves just one sense. Thus it is possible for the undistracted listener to be completely immersed in the broadcast. If the broadcast is educational, cultural, and fact-based the listener may devote 100% of their attention to that show. If encouraged, the listener may also request a QSL which is a valuable opportunity for the broadcaster to communicate with them again. The listener’s curiosity may be piqued about a particular subject they can later research. Or they may store away their colorful QSLs and/or pleasant memories of tuning into a faraway station until they have a chance to visit the country they spent so many hours listening to.
Just as the author of a good book can form a lifelong bond with the reader, so can shortwave radio. I am amazed at the number of listeners who started with shortwave half a century ago and are often featured on DX program segments. DXers frequently mourn long-gone radio stations as they do close friends who have passed on. Shortwave radio is a powerful medium that can emotionally connect with listeners for many decades.
Shortwave radio can vastly broaden the horizons of individuals around the world. Radios are inexpensive and broadcasts reach every point on the globe. Powerful broadcasts cross international borders with ease. Radio frequently offers a voice different from what the listener hears in their local community. That can lead to a deeper understanding of distant countries and cultures. Better understanding and the freedom to hear new ideas is a building block for the antonym of war; peace.
Radios to Ukraine

Hi Thomas,
Following World Radio Day on the theme “Radio & Peace”, I draw your attention to this article online on the Radioworld website: http://www.radioworld.com
I am aware that this is a politically very sensitive subject… But I wonder why the receiver that is distributed does not allow listening to short waves? Nowadays, there are affordable receivers that allow shortwave listening
This example is a good illustration of the indispensable role that radio still plays in today’s world.
Kind regards.

Many thanks to Tracy, Tim, and Paul for sharing these World Radio Day items!
Washington maintains a waterfront radio tower in the Florida Keys to broadcast programming aimed at encouraging democracy and press freedom in Cuba, and on Sunday that area in Marathon was the landing spot for a group of migrants fleeing the island. A boat of 25 migrants arrived on the shores of Sister Creek, home to a Radio Martí transmission station on Sunday morning, said Adam Hoffner, assistant chief patrol agent for U.S. Customs and Border Protection’s Miami operations. The landing was one of two known migrant arrivals in the Keys on Sunday, with another 28 Cubans arriving on private property in Key Largo. While the government-run broadcasting agency targets Cuban listeners with Spanish programming, Radio Martí reports typically discourage the kind of voyage that reportedly landed some Cubans on or near Martí property, said Tomás Regalado, the former Miami mayor who also recently ran the agency that oversees Radio and TV Martí. “Historically, the migrant situation was something that was treated as news,” Regalado said. “But with the caveat that it’s a very dangerous trip and not recommended.” [Read more here…]
A nonprofit organization based in the U.S. is supplying Ukrainian forces with advanced electronic warfare gear assembled from simple off-the-shelf components. The secret is a new technology known as Software Defined Radio (SDR) which can locate Russian radio emitters, from command centers to drone operators. Previously this sort of capability required expensive, high-grade military equipment.
Serge Sklyarenko says his organization, American Ukrainian Aid Foundation, based in New York, is supplying Ukrainian intelligence with a number of the versatile SDR radio kits.
“The beauty of them is they are software defined, meaning they can be reprogrammed in the field to suit a multitude of use cases,” Sklyarenko told me.
In a traditional radio set, the signal from an antenna is processed by dedicated hardware – amplifiers, filters, modulator/demodulators and other components. This means that each radio set is dedicated to one particular type of radio signal, whether it is a 5G cellphone, AM radio, digital television or WiFi. In Software Defined Radio, the only dedicated hardware is the antenna. All the signal processing is carried out digitally with a computer. Simply by changing the programming, an SDR can extract the signal for cellphone, radio, Bluetooth, or any other defined waveform. One device can do everything. [Continue reading…]
On January 10, 1991, the U.S. Army Intelligence School Devens (USAISD) introduced the Basic Morse Mission Trainer to the 98H Morse intercept operator and 98D emitter identifier/locator advanced individual training courses. This system revolutionized the training of Morse code copying skills for both students and instructors, reducing course attrition, and turning out better trained operators faster. Continue reading →
The clear and periodic pattern of fast radio bursts may originate from a distant neutron star.
Astronomers at MIT and universities across Canada and the United States have detected a strange and persistent radio signal from a far-off galaxy that appears to be flashing with surprising regularity.
The signal is classified as a fast radio burst, or FRB — an intensely strong burst of radio waves of unknown astrophysical origin, that typically lasts for a few milliseconds at most. However, this new signal persists for up to three seconds, about 1,000 times longer than the average FRB. Within this window, the team detected bursts of radio waves that repeat every 0.2 seconds in a clear periodic pattern, similar to a beating heart.
The researchers have labeled the signal FRB 20191221A, and it is currently the longest-lasting FRB, with the clearest periodic pattern, detected to date.
The source of the signal lies in a distant galaxy, several billion light-years from Earth. Exactly what that source might be remains a mystery, though astronomers suspect the signal could emanate from either a radio pulsar or a magnetar, both of which are types of neutron stars — extremely dense, rapidly spinning collapsed cores of giant stars.
“There are not many things in the universe that emit strictly periodic signals,” says Daniele Michilli, a postdoc in MIT’s Kavli Institute for Astrophysics and Space Research. “Examples that we know of in our own galaxy are radio pulsars and magnetars, which rotate and produce a beamed emission similar to a lighthouse. And we think this new signal could be a magnetar or pulsar on steroids.”
The team hopes to detect more periodic signals from this source, which could then be used as an astrophysical clock. For instance, the frequency of the bursts, and how they change as the source moves away from Earth, could be used to measure the rate at which the universe is expanding. [Continue reading…]
Transmission company CRA looks at possibility for reusing analog transmission facilities
Czech transmission services company ?eské Radiokomunikace (CRA) is testing the DRM medium-wave digital radio system on 954 kHz.
According to a tweet from Marcel Prochazka, director of legal and regulatory affairs for CRA, the transmissions are originating from ?eské Bud?jovice in South Bohemia and operating at a power of 3.16 kW from a 107-meter HAAT antenna. Continue reading →
Yaesu is introducing a new 100 watt SDR transceiver to their product line: the Yaesu FT-170.
The Yaesu FT-710 will cover 160-6 meters with 100 watts output. There are two other Japanese market versions: the FT-710M and FT-710S which are 50 and 10 watt respectively.
This general coverage rig will feature “AESS”–Yaesu’s ‘Acoustic Enhanced Speaker System’ which “creates the high-fidelity audio output.” Yaesu notes that the FT-710 utilizes, “the advanced digital RF technology introduced in the FTDX101 and FTDX10 series.”
KYIV, Ukraine — During the early morning hours of Feb. 24, as Russian missiles struck targets across Ukraine in the opening hours of the full-scale war, the Ukrainian military’s Army FM radio station went underground.
The team of seven army officers and about 10 civilian personnel abandoned their studio on the top floor of a downtown Kyiv building and relocated into a nearby basement. Inside the dank and dark underground space, they connected a mixing board and a couple of laptops to a mobile radio system, which the station’s reporters had previously used to report from the Donbas trenches.
“I just grabbed my Kalashnikov and went to work,” said Oleksandr Yurchenko, 32, a Ukrainian army second lieutenant assigned to Army FM.
While a Russian invasion force advanced to the outskirts of Kyiv in the war’s perilous first few days, the Army FM team stayed at their posts and worked in six-hour shifts to keep their programs running 24/7. They constructed makeshift beds from shipping pallets and stocked the basement studio with food and water. Body armor vests and Kalashnikovs occupied all available shelves and empty corners.
From this jury-rigged basement studio, Army FM continued to transmit information and entertainment programs to listeners across Ukraine — including into territories Russian forces invaded and occupied. [Continue reading…]
On Hackaday Chris Lott WD4OLP writes about DL1DN’s aluminum foil 20cm antenna for 28 MHz (10m) operation
David DL1DN, is an Amateur Radio enthusiast with a penchant for low-power (QRP) portable operations. Recently he was out and about, and found that 10 m propagation was wide open. Not discouraged by having forgotten his antenna, he kludges up a makeshift one using a 20 cm length of aluminum foil.
ATS-25 with Binns 4.1 firmware Review Now Posted. […] There were 7 different versions in the beta stage. New audio file added as well (Sync when it does not work so well, which is NOT all the time). Might be one more update before release (not sure right now).
Every so often, our star fires off a plasma bomb in a random direction. Our best hope the next time Earth is in the crosshairs? Capacitors.
TO A PHOTON, the sun is like a crowded nightclub. It’s 27 million degrees inside and packed with excited bodies—helium atoms fusing, nuclei colliding, positrons sneaking off with neutrinos. When the photon heads for the exit, the journey there will take, on average, 100,000 years. (There’s no quick way to jostle past 10 septillion dancers, even if you do move at the speed of light.) Once at the surface, the photon might set off solo into the night. Or, if it emerges in the wrong place at the wrong time, it might find itself stuck inside a coronal mass ejection, a mob of charged particles with the power to upend civilizations.
The cause of the ruckus is the sun’s magnetic field. Generated by the churning of particles in the core, it originates as a series of orderly north-to-south lines. But different latitudes on the molten star rotate at different rates—36 days at the poles, and only 25 days at the equator. Very quickly, those lines stretch and tangle, forming magnetic knots that can puncture the surface and trap matter beneath them. From afar, the resulting patches appear dark. They’re known as sunspots. Typically, the trapped matter cools, condenses into plasma clouds, and falls back to the surface in a fiery coronal rain. Sometimes, though, the knots untangle spontaneously, violently. The sunspot turns into the muzzle of a gun: Photons flare in every direction, and a slug of magnetized plasma fires outward like a bullet.
The sun has played this game of Russian roulette with the solar system for billions of years, sometimes shooting off several coronal mass ejections in a day. Most come nowhere near Earth. It would take centuries of human observation before someone could stare down the barrel while it happened. At 11:18 am on September 1, 1859, Richard Carrington, a 33-year-old brewery owner and amateur astronomer, was in his private observatory, sketching sunspots—an important but mundane act of record-keeping. That moment, the spots erupted into a blinding beam of light. Carrington sprinted off in search of a witness. When he returned, a minute later, the image had already gone back to normal. Carrington spent that afternoon trying to make sense of the aberration. Had his lens caught a stray reflection? Had an undiscovered comet or planet passed between his telescope and the star? While he stewed, a plasma bomb silently barreled toward Earth at several million miles per hour. [Continue reading at Wired…]

As Vladimir Putin tightens his stranglehold on what his citizens see and hear, will radio once again become an effective way to get outside voices into Russia?
For the time being, U.S. broadcasting officials believe the best way to get their content to Russia’s population is still through the internet, despite all of Putin’s attempts to control it. Activists in the United States and Europe, however, are convinced that in a wartime situation, those wanting to reach Russians should be trying everything – including shortwave radio, the mainstay of Cold War broadcasting by the Voice of America (VOA) and Radio Free Europe/Radio Liberty (RFE/RL).
The U.S. government’s reluctance to return to shortwave has led to the odd spectacle of American volunteers taking broadcasting into their own hands. Activists have crowdfunded projects to transmit on shortwave channels programs produced by VOA and RFE/RL that the government declines to broadcast with its own transmitters.
Shortwave broadcasting uses high frequencies that can reach across continents. During Soviet rule, VOA, RFE/RL, the British Broadcasting Corporation (BBC) and other stations used shortwave to punch news, religious programs and forbidden Western music through the Iron Curtain. Soviet jamming stations tried to drown out the broadcasts, but much of the content got through.
With the collapse of the Soviet Union and the rise of the internet in Russia, foreign shortwave broadcasting tapered off. Boris Yeltsin let RFE/RL open local stations in some 30 Russian cities, but under Putin they were forced to close because of Russian laws. The United States then switched its radio and video services for Russians almost entirely to the web and social networks.
Since the war began, however, Russian authorities have increasingly blocked from the internet any content that criticizes the war or Putin’s rule. Many Russians use VPNs and other software to get around the blocks, and have come to the US broadcasters’ websites and social network feeds in droves. But Russian officials are working feverishly to block these circumvention tools, and may be able to determine which citizens are using them. [Continue reading on the IPA website…]
With music consumption having long ago moved to a streaming model in many parts of the world, it sometimes feels as though, just like the rotary telephone dial, kids might not even know what a radio was, let alone own one. But there was a time when broadcasting pop music over the airwaves was a deeply subversive activity for Europeans at least, as the lumbering state monopoly broadcasters were challenged by illegal pirate stations carrying the cutting edge music they had failed to provide. [Ringway Manchester] has the story of one such pirate station which broadcast across the city for a few years in the 1970s, and it’s a fascinating tale indeed.
It takes the form of a series of six videos, the first of which we’ve embedded below the break. The next installment is placed as an embedded link at the end of each video, and it’s worth sitting down for the full set.
The action starts in early 1973 when a group of young radio enthusiast friends, left without access to a station of their taste by Government crackdowns on ship-based pirate stations, decided to try their hand with a land-based alternative. Called Radio Aquarius, it would broadcast on and off both the medium wave (or AM) and the FM broadcast bands over the next couple of years. Its story is one of improvised transmitters powered by car batteries broadcasting from hilltops, woodland, derelict houses, and even a Cold War nuclear bunker, and develops into a cat-and-mouse game between the youths and the local post office agency tasked with policing the spectrum. Finally having been caught once too many times, they disband Radio Aquarius and go on to careers in the radio business.
The tale has some tech, some social history, and plenty of excitement, but the surprise is in how innocent it all seems compared to the much more aggressively commercial pirate stations that would be a feature of later decades. We’d have listened, had we been there!
