Paul spots an AOR AR-3000A in “20 Days in Mariupol”

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

Hi Thomas,

“20 Days in Mariupol” won this year’s Oscar for Best Documentary.
The movie is about the Russian siege to that city in the opening days
of the Ukraine invasion, as recounted by a filmmaker located there.

There is a segment of the movie about Russia’s use of propaganda to
demoralize the local population. The still photo shows an AOR AR-3000a
communications receiver playing a Russian broadcast, trying to
convince the city’s inhabitants that they cannot stop the invasion.

That radio was reviewed on The SWLing Post a few years ago:

A review of the AOR AR-3000A Wideband Receiver

The sad and grim movie is available for free viewing at PBS:

20 Days in Mariupol

The part showing the radio starts around the 35:16 mark.

Thank you for sharing this, Paul.

The pirate-radio DJ who took on Putin (The Economist)

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…]

In South Sudan, Refugees Train as Radio Hosts to Keep Residents Informed (VOA News)

JOHANNESBURG, SOUTH AFRICA —

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 →

Digital Library Of Amateur Radio And Communications Is A Treasure Trove (Hackaday)

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 Need Your Help During Solar Eclipses! (NASA)

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.

Hackers Disrupt Russian Radio (Radio World)

Air raid sirens broadcast in a dozen cities

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…]

Radio Closures Hit Afghanistan Hard (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

Many thanks to SWLing Post contributor, Paul Jamet, who writes:

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

Portable radios take overseas trip to Ukraine, local fundraising continues
https://www.radioworld.com/news-and-business/portable-radios-successfully-delivered-to-ukraine-local-fundraising-continues

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.

Radio Martí news: Migrants land by Keys broadcasting tower promoting Cuban democracy (Miami Herald)

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…]

Ukraine Uses Off-The-Shelf Electronics To Target Russian Communications (Forbes)

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…]

Innovation on Morse Code for the US Military (SOFREP)

Astronomers detect a radio “heartbeat” billions of light-years from Earth (MIT)

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…]

Ukraine’s ‘Army FM’ Radio Adapts To Full-Scale War (CoffeeOrDie)

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…]
