That’s ‘Comrade’ To You! North Korea Fights To Purge Outside Influences On Language (NPR)

SEOUL — In the show Crash Landing on You, a rich South Korean woman accidentally paraglides into North Korea, where she is rescued by an army officer and falls in love with him. The series, which was released on Netflix in 2019, was a hit across the Korean Peninsula — including in the North, where it circulated on smuggled thumb drives.

“It created quite a stir, with Kim Jong Un even forbidding people from watching it,” says Kang Nara, a North Korean defector in Seoul who served as a consultant to the show.

That’s not surprising, as all South Korean content is effectively banned in North Korea.

Kang says she found Crash Landing on You appealing for its realistic depictions of life in the North, including the language. As in real life, North Koreans in the drama, for example, call their intimate partners “comrade” instead of “honey.”

But differences in language from the South are a sensitive issue for the North Korean regime. It has fought for more than half a century to purge North Korea’s language of foreign influences, and for roughly two decades to keep out southern-style expressions that northerners are gleaning from bootlegged South Korean TV dramas, movies and K-pop music.

Microsoft catches hackers using Morse Code to help cover their tracks (CyberScoop)

Clever hackers use a range of techniques to cover their tracks on a target computer, from benign-looking communication protocols to self-erasing software programs.

It’s not very often, though, that digital attackers turn to Morse Code, a 177-year-old signaling system, for operational security. Yet that’s exactly what played a part in a year-long phishing campaign that Microsoft researchers outlined on Thursday.

Morse Code — a method of representing characters with dots and dashes popularized by telegraph technology — was one of several methods that the hackers, whom Microsoft did not identify, used to obscure malicious software. It’s a reminder that, for all of their complexities, modern offensive and defensive cyber measures often rest on the simple concept of concealing and cracking code. Continue reading

The Buzzer (Twenty Thousand Hertz podcast)

This episode was written and produced by Olivia Rosenman.

Since World War I, countries around the world have been broadcasting mysterious numerical messages via shortwave radio. Though concrete evidence is hard to come by, the general consensus is that these coded messages are meant for undercover agents operating abroad. And one particular Russian station may have an even more sinister purpose. Featuring computer engineer Andrus Aaslaid, historian Maris Goldmanis, and documentary photographer Lewis Bush.

Cuba Jamming Ham Radio? Listen For Yourself (IEEE Spectrum)

A public SDR network triangulates the island as the source of mystery signals

By Stephen Cass

As anti-government protests spilled onto the streets in Cuba on July 11, something strange was happening on the airwaves. Amateur radio operators in the United States found that suddenly parts of the popular 40-meter band were being swamped with grating signals. Florida operators reported the signals were loudest there, enough to make communication with hams in Cuba impossible. Other operators in South America, Africa, and Europe also reported hearing the signal, and triangulation software that anyone with a web browser can try placed the source of the signals as emanating from Cuba.

Cuba has a long history of interfering with broadcast signals, with several commercial radio stations in Florida allowed to operate at higher than normal power levels to combat jamming. But these new mystery signals appeared to be intentionally targeting amateur radio transmissions. A few hours after the protest broke out on the 11th, ham Alex Valladares (W7HU) says he was speaking with a Cuban operator on 7.130 megahertz in the 40-meter band, when their conversation was suddenly overwhelmed with interference. “We moved to 7170, and they jam the frequency there,” he says. Valladares gave up for the night, but the following morning, he says, “I realize that they didn’t turn off those jammers. [Then] we went to [7]140 the next day and they put jamming in there.”[]

New school at home of former radio station on track for autumn launch (Coventry Telegraph)

Houlton School, where Rugby Radio Station once stood, is set take its first influx of pupils in September

Plans for a new school at the historic former home of Rugby Radio Station are being fine-tuned and remain on track for a September start.

Houlton School, which will be named after the town in America that received the first transatlantic voice broadcast from Rugby Radio Station in 1927, will take its first influx of 180 Year 7 pupils this autumn.

The school, which forms part of the 6,200-home urban extension in Houlton, east of Rugby town centre, will take a new year group of 180 pupils every 12 months.

Michael McCulley, the school’s Principal Designate, said: “Whilst building a fantastic £39m new school during three lockdowns has had its challenges, we are also acutely aware that we have had a completely blank page from which to develop our exciting curriculum and pastoral programme.

“This freedom has been important as we have needed to evolve to the changing needs of our first group of students.[]

Ham Radio Outlet to open store in Florida (Amateur Radio Newsline)

Ham Radio Outlet, the nationwide amateur radio retailer in the US, has announced that its ongoing expansion plans will include a store in the state of Florida. The new store will join 12 already open in such states as California in the West, where the company is based, to Delaware in the East, Arizona and Texas in the South, New Hampshire in the North. The company’s announcement on social media set off a wave of speculation about the new location, especially on Instagram where the company wrote, “We’re not telling yet! We’re open to suggestions.” The closest Ham Radio Outlet to Florida is in Atlanta, Georgia. The company, which calls itself the world’s largest supplier of amateur radio equipment, is also known for shipping internationally.

Old is gold: In times of satellite & internet, Pune cops keep Morse Code in use as a robust stand-by communication mode (The Indian Express)

Every Sunday, an operator with Pune Police’s wireless wing sends a Morse Code message to the office of the Director General of Police, Maharashtra.

IN THE era of satellite communication, which involves transmitting signals into space and back, and internet based systems transferring gigabytes of data in a flash, police have kept alive the age-old system of Morse Code – a primitive method of sending messages in the form of dots and dashes.

Every Sunday, an operator with Pune Police’s wireless wing sends a Morse Code message to the office of the Director General of Police, Maharashtra. While this is their way of paying tributes to one of the earliest modes of telecommunication, it is primarily a way of maintaining a robust stand-by mode of message delivery in case all other means of communication fail.

Pune City police have recently started a series of tweets featuring the communication systems used by the police and their evolution till date. On Sunday, Pune Police Commissioner Amitabh Gupta tweeted, “As an ode to the beginning of wireless communications, the Commissioner’s Office still uses Morse Code to transmit Messages every Sunday.”[]

Antiques Roadshow: Spy radio disguised as toolbox found in garden shed worth huge sum (The Express)

ANTIQUES ROADSHOW saw a World War II spy radio which was disguised as a toolbox fetch a huge valuation when it travelled to Kenilworth Castle.

Antiques Roadshow’s expert Mark Smith marvelled at the ingenuity of a spy radio which was used in World War Two in a recent episode. The item, from the outside, was made to look like a toolbox but when opened, displayed a detailed radio which could be “powered by any source”. So how much was it worth? Mark put a £10,000 to £15,000 price tag on it.[]

Einstein Listened (WNYC)

Former WNYC director Seymour N. Siegel suggested that WNYC once received fan mail from Einstein. As I continue to look far and wide for evidence of this alleged bit of praise, I can’t help but wonder, what broadcast prompted the great man to write? Alas, so far, the document has eluded me. But, we do know that the father of the theory of relativity was a subscriber to both the WNYC and WQXR program guides. And we have no less than Erwin Panofsky, the noted German-American art historian and friend of Einstein’s, to thank for that.

It all began when the distinguished gang at the Institute for Advanced Study in Princeton, New Jersey decided to chip in and build the Nobel laureate a “high-fidelity” radio for his 70th birthday. The 1949 gift included subscriptions to the WNYC, WQXR, and WABF program guides.[]

G6QA’s Slow Morse Morning Club

While some SWLs and radio listeners dislike Web-based SDRs because they don’t feel like “real radio” there’s no denying that they do offer up listening opportunities you might not otherwise be able to enjoy from home.

Case in Point

Friend and SWLing Post contributor, Pete Madtone, has been enjoying dropping in on a local Slow Morse Morning Club via the G0XBU WebSDR. He’s shared a bit of recorded audio with me in the past, but this morning he sent me a link to the SDR with the frequency of the class in progress.

We both listened live with Pete and the repeater in the UK, and me in the States.

The class is wonderful and what I consider an ideal use of local repeaters.  Linda serves up a sentence of slow code, then reads back what she sent. The others on the repeater then chime in with their copy–what they copied and what they missed. There really is no better way to build up your CW chops in the beginning than to do this–it’s interactive, supportive, and the audio very clear via FM on the repeater. It’s proper distance instruction using my favorite medium: radio!

Plus, well, the whole thing has some serious charm. I started an audio recording of the class this morning. Here’s it is for your enjoyment:

Thanks for the tip this morning, Pete!

Sources on Cold War Radio, Paradoxes, Maoism, and Noise (Wilson Center)

Radio Tirana emerged as a global Communist voice in the 1970s, reaching Brazilian guerillas in Araguaia, Maoist factions across Asia, Africa, and Latin America, and many other listeners around the world. Elidor Mëhilli explains how this came to be.

“Dear Radio Tirana,” the letter begins, “here in the Alps we can hear you well, and we are especially fond of your propaganda directed at the Italian Communist Party.” The letter is dated April 12, 1976 but its Italian authors are not named. After a final greeting “Viva Mao e Viva Stalin,” they have simply signed off “a group of true Communists.”[i]

Two months earlier, in Entroncamento, Portugal, someone has penned a letter to the same station. “Camaradas,” his note begins, “I am a worker (a porter) who listens regularly to your Portuguese-language broadcasts.” The letter then proceeds with complaints about the fate of Communism in Portugal, with questions about Albania’s foreign policy, about why Radio Tirana spoke so infrequently about Portugal, about sports, about whether a trip to the Balkans might be possible.[ii]

By March, in Arequipa, Peru, a thirty-year-old places the recipient’s address on a small envelope: Señor Director, Radio Tirana, Albania.

He is among early Peruvian intellectuals who have been drawn to Mao Zedong’s ideas. Having completed a thesis on the topic, he is on his way to becoming a professor within a few years. “Unfortunately, I have to tell you that it’s been over a year that I do not receive your broadcasts,” he writes, “I think that it might due to the interference of the imperialist Yankees or perhaps the Soviet social-imperialists.”[iii]

Once a modest station, Radio Tirana had become a global Communist voice by the 1970s, reaching Brazilian guerillas in Araguaia, teeny-tiny Maoist factions across Asia, Africa, and Latin America, far-flung dots scattered across oceans and seas. This turned the station into a kind “of superpower of its kind” as author Ardian Vehbiu has put it. Officials embraced this role, broadcasting in numerous languages—English, Arabic, French, Italian, Greek, Portuguese, German, Indonesian—and beaming anti-capitalist and anti-Soviet messages day after day.[]

World Wide Waves: The Sounds of Community Radio (BBC World Service)

We think we live in a digital age, but only half the world is currently online. Across the globe, small radio stations bind remote communities, play a dazzling array of music, educate, entertain and empower people to make change. Cameroon’s Radio Taboo, in a remote rainforest village 100 miles off the grid, relies on solar power; its journalists and engineers are all local men and women, and some of its audience listen on wind-up radios. In Tamil Nadu, Kadal Osai (“the sound of the ocean”) broadcasts to the local fishing community about weather, fishing techniques—and climate change. In Bolivia, Radio Nacional de Huanuni is one of the last remaining stations founded in the 1950s to organise mostly indigenous tin miners against successive dictatorships; its transmitters are still protected by fortified walls.

For World Radio Day, we visit community stations around the globe and celebrate the enduring power, possibilities and pleasures of the airwaves.

New phishing attack uses Morse code to hide malicious URLs (Bleeping Computer)

A new targeted phishing campaign includes the novel obfuscation technique of using Morse code to hide malicious URLs in an email attachment.

Samuel Morse and Alfred Vail invented morse code as a way of transmitting messages across telegraph wire. When using Morse code, each letter and number is encoded as a series of dots (short sound) and dashes (long sound).

Starting last week, a threat actor began utilizing Morse code to hide malicious URLs in their phishing form to bypass secure mail gateways and mail filters.

BleepingComputer could not find any references to Morse code being used in phishing attacks in the past, making this a novel obfuscation technique

The novel Morse code phishing attack
After first learning of this attack from a post on Reddit, BleepingComputer was able to find numerous samples of the targeted attack uploaded to VirusTotal since February 2nd, 2021.

The phishing attack starts with an email pretending to be an invoice for the company with a mail subject like ‘Revenue_payment_invoice February_Wednesday 02/03/2021.'[]

Father Lombardi: Mission of Vatican Radio in service of the Pope (Vatican News)

We reproduce excerpts from an article written on the 90th anniversary by the former Director of Vatican Radio, which were published in the latest issue of La Civiltà Cattolica.

By Fr Federico Lombardi, SJ

On 12 February 2021 it will be exactly 90 years since Pope Pius XI inaugurated the new Vatican Radio Station – built at his request by Guglielmo Marconi and entrusted to the care of Jesuit Father Giuseppe Gianfranceschi as its first director. The “mission of Vatican Radio was clear from the beginning: to be an instrument at the service of the Pope for his ministry of proclaiming the Gospel in the world and guiding the universal community of the Catholic Church. This mission has been preserved over time and has been reaffirmed several times by the Popes, guaranteeing a strong identity of the institution. […]

The voice of the Pope
Vatican Radio […] was founded in 1931, in the context of the rapid establishment of the new Vatican City State […]. The radio station built by Marconi was at the forefront of the technology of the time, and was able to provide telegraphic and radio service completely independently from Italy. Thanks to short-wave technology, in an “ether” not yet overcrowded with countless transmissions, it was possible to be heard on other continents with a rather low power. At the beginning of its existence, Vatican Radio was the instrument thanks to which the Catholics of the world could hear the voice of the Pope directly for the first time. […]

The 1930s were years of the power of totalitarianism. Pius XI’s positions were courageous and, in the thickening of the storm, he looked to the Church with confidence. The demand for broadcasts in different languages to guide and support the faithful in European countries grew rapidly. Father Filippo Soccorsi, appointed to lead the Radio in 1934 (at 34 years old!), after the untimely death of Fr. Gianfranceschi, not only dedicated himself to improving the technical structures — such as the new antenna towering over the Vatican gardens, known as “The Pope’s Finger” — but promptly grasped the expectation to make the Radio grow also in the content of its programming. Thus, in 1936, the Vatican Broadcasting Corporation was accepted into the International Broadcasting Union with a recognition of its special nature, which authorised it to carry out radio activities without any geographical limitations. Because of the limited means available, Fr Soccorsi asked for the collaboration of Jesuit brethren from various countries for the editing and presentation of the texts. The German-language broadcasts were particularly important.

In the tragedy of war: for peace and solidarity with the suffering
[…] On the eve of the war, in 1939, there were regular broadcasts in Italian, French, English, German, Spanish, Portuguese, Polish, Ukrainian, and Lithuanian, and the station was able to be a point of reference for the Church in the immense tragedy, playing its role of denouncing violence, supporting victims and members of the resistance, and encouraging hope. The “Radio-messages” of Pius XII in wartime, eagerly awaited and listened to with great attention throughout Europe, remain famous. His was the loudest and most authoritative voice rising above the warring parties in those terrible years, calling for justice and peace.

During the war, however, Vatican Radio became famous for another service: it was in fact a fundamental instrument of the great commitment desired by Pius XII with the “Information Office of the Secretariat of State,” set up in 1939 to track down missing civilians and soldiers and prisoners; to provide information to their families and, if possible, to re-establish among them at least a link of greeting and remembrance. […]

Vatican Radio devoted specific broadcasts to requesting news about the missing and broadcasting short messages from the families to the prisoners, whose names were slowly spelled out by the “metallic” voice of the speakers. These broadcasts reached 70 hours per week, with peaks of 12-13 hours per day. Between 1940 and 1946, a total of 1,240,728 messages were broadcast in 12,105 hours of actual transmission time. In some cases, the transmissions were broadcast over loudspeakers in prison camps. The testimonies of gratitude for this service were numerous and moving. This is one of the most beautiful pages in the history of Vatican Radio.

A voice for the “Church of Silence”
With the end of the war, Vatican Radio accompanied with its broadcasts the climate of moral and spiritual reconstruction of the countries devastated by the conflict, while preparations were in full swing for the great Holy Year of 1950, a time of renewed vitality of the Church.

But in the meantime, most of Eastern Europe fell under the oppression of the communist regimes, and the Catholic Church became the object of harsh persecution in many countries. This was an historic challenge for Vatican Radio, which was practically the only way through which the faithful could nurture their bond with the Pope and the universal Church and receive support for their faith. Even with limited resources, programmes in the languages of Eastern European countries became more numerous and were given more airtime. At the end of the 1940s, the programme in Polish — which together with Italian, English, French, Spanish and German had always been one of the main languages of transmission — was joined by those in Czech, Slovak, Hungarian, Lithuanian, Latvian, Russian, Croatian, Slovenian, Ukrainian, Romanian, Bulgarian, Belarusian and, shortly afterwards, Albanian. For decades, throughout the time of oppression, the broadcasts of Vatican Radio offered a regular and sure appointment for the faithful, religious, priests and bishops deprived of the freedom to express and live their faith.

There would be countless stories to tell about those years. In certain countries and in certain periods of the harshest persecution, listening to Vatican Radio was absolutely forbidden and seriously dangerous: it could be the cause of serious penalties, up to imprisonment and even — in some cases — the death sentence. For some languages, such as Polish or Slovak, the audience was high, while for others, where Catholics were a minority, there were not many listeners. But the principle that guided the fathers of the Radio, according to the Pope’s intention, was not the vastness of the audience, but the situation of need of the listeners. That is why the languages of broadcasting to Eastern countries have always represented more than half of the languages used by Vatican Radio. When, after many years, the walls fell, the gratitude of the faithful and the people could finally express itself in moving forms, such as the more than 40,000 letters that arrived at the Ukrainian Section in the first year after the fall of the Soviet regime, or the bestowal of the award of the Albanian State for the work of Vatican Radio. […]

Communication for communion
In 1970 the editorial offices and studios of Vatican Radio moved to Palazzo Pio, in front of Castel Sant’Angelo, providing adequate space in what would become the main headquarters of the station for decades. In 1973 Father Roberto Tucci […] succeeded Father Martegani in the general direction. We were on the eve of the Holy Year 1975 and the Radio was completely mobilised. It was not only a matter of broadcasting live the great papal celebrations, audiences and events, and of giving adequate information in all languages so that the universal Church felt involved, but also of providing a service for pilgrims arriving in Rome from all over the world. […]

Pasquale Borgomeo, who would become a dynamic and creative director of programmes; and Father Félix Juan Cabasés, in charge of the “Central Editorial Office,” later the “Documentation Service”: The former would greatly cultivate the valuable international relations of the station, in particular with the European Broadcasting Union (EBU); the latter would leave a lasting mark in the organisation of documentation and editorial programming. […]

Vatican Radio thus reached maturity, with increasing professional and journalistic quality, which makes it not only the beating heart of daily communication in the universal Church — “communication for communion”, as the Council hoped — but also an active protagonist in the wider world of Catholic and lay communication in the life of the Church.[]

New quantum receiver the first to detect entire radio frequency spectrum (Phys.org)

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.

Army researchers built the quantum sensor, which can sample the radio-frequency spectrum—from zero frequency up to 20 GHz—and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.

The Rydberg sensor uses laser beams to create highly-excited Rydberg atoms directly above a microwave circuit, to boost and hone in on the portion of the spectrum being measured. The Rydberg atoms are sensitive to the circuit’s voltage, enabling the device to be used as a sensitive probe for the wide range of signals in the RF spectrum.

“All previous demonstrations of Rydberg atomic sensors have only been able to sense small and specific regions of the RF spectrum, but our sensor now operates continuously over a wide frequency range for the first time,” said Dr. Kevin Cox, a researcher at the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory. “This is a really important step toward proving that quantum sensors can provide a new, and dominant, set of capabilities for our Soldiers, who are operating in an increasingly complex electro-magnetic battlespace.”

The Rydberg spectrum analyzer has the potential to surpass fundamental limitations of traditional electronics in sensitivity, bandwidth and frequency range. Because of this, the lab’s Rydberg spectrum analyzer and other quantum sensors have the potential to unlock a new frontier of Army sensors for spectrum awareness, electronic warfare, sensing and communications—part of the Army’s modernization strategy.

“Devices that are based on quantum constituents are one of the Army’s top priorities to enable technical surprise in the competitive future battlespace,” said Army researcher Dr. David Meyer. “Quantum sensors in general, including the one demonstrated here, offer unparalleled sensitivity and accuracy to detect a wide range of mission-critical signals.”

The peer-reviewed journal Physical Review Applied published the researchers’ findings, Waveguide-coupled Rydberg spectrum analyzer from 0 to 20 GigaHerz, co-authored by Army researchers Drs. David Meyer, Paul Kunz, and Kevin Cox[]

Virus and distance learning by radio (1937, 1946) (AE5X Blog)

Six to eight decades ago polio was one of the most feared diseases in the US. In 1952 alone, 60,000 children were infected, 3000 died and many more were paralyzed.
The most severe outbreaks were in 1937 and 1946. My father was a victim of the 1946 epidemic, suffering minor paralysis in one leg as a child.

In 1937, many schools around the country closed, as did public pools, movie theaters and parks. But the Chicago public school system took an innovative approach.

During that period, 80% of US households contained a radio. This allowed 325,000 children in grades 3-8 to continue their education at home via radio lessons aired by six Chicago radio stations (WENR, WLS, WIND, WJJD, WCFL, WGN) that donated time for the purpose.

Program schedules for each day were printed in the morning paper. Home with more than one radio & more than one child often set up radios in different rooms so that each child could hear the appropriate grade’s lesson.

This continued for one month…until schools reopened in late September of that year.

Curriculum was developed by teachers and monitored over the air by school officials. After each episode, a limited number of teachers were available for phone calls. A large number of the calls were from parents distressed that they could not clearly receive the broadcasts.[Continue reading…]

BBC Woofferton Early Days (Ludlow Heritage News) [PDF]

Very few structures are left in the Ludlow area which can be traced back to the Second World War. However, look five miles south of the town towards the rise of the hills and a tracery of masts can be seen. Go closer, and a large building can be found by the road to Orleton, surrounded now by a flock of satellite dishes, pointing upwards. The dishes are a sign of the recent past, but the large low building was made for the war-time radio station aimed at Germany.

This little history attempts to tell the story of the British Broadcasting Corporation’s transmitting station at Woofferton near Ludlow in Shropshire during the first years of its existence. When and why did the BBC appear in the Welsh border landscape with a vast array of masts and wires strung up in the air? The story begins in 1932, when the BBC Empire Service opened from the first station at Daventry in Northamptonshire. Originally, the service, to link the Empire by wireless, was intended to be transmitted on long-wave or low frequency. But, following the discovery by radio amateurs that long distance communication was possible by using high frequency or short waves, the plan was changed. Later in the decade, the BBC expanded the service by also broadcasting in foreign languages. Although Daventry had a distinguished name in the broadcasting world, it was never technically the best place for a short-wave site, being on a hill and close to a growing town.
