The silence of Radio Canada International (Open Canada)

The former head of CBC News laments the evisceration of CBC’s international service and Canada’s shrinking voice in the world

For a country that once regarded itself as one of the world’s leading middle powers, Canada’s voice on the international scene is a strikingly quiet one these days. It reminds me of the line from that famous “dead parrot” sketch in Monty Python: “bereft of life, it rests in peace.”

The latest sign of this is the decision by CBC/Radio-Canada to implement changes that have effectively smothered Radio Canada International (RCI), its fabled global audio and online service that has helped serve as “Canada’s Voice to the World” for more than a half century.

In a December announcement replete with CBC doublespeak, the CBC unveiled a “major transformation” of RCI that, it claimed, would ensure RCI remains “a strong and relevant voice” in this century’s media landscape. Not surprisingly, the practical impact of these changes is precisely the opposite.

Flipping RCI’s historic mission on its head, the service will now focus more on ethnic minorities within Canada rather than on continuing to produce programs tailored uniquely for international audiences. More than half of RCI’s beleaguered staff have been laid off.

This latest CBC battering of RCI — a pattern that has gone on for decades — triggered considerable criticism. In February, a group of 32 prominent Canadians sent an open letter to Prime Minister Justin Trudeau and other senior government ministers urging that the CBC scrap its planned strategy and appoint an independent committee to plan a rebuild of the international service: “In an interconnected world in search of truth, facts and honest journalism, countries like Canada cannot abdicate their role on the world stage.” Its signatories included former prime minister Joe Clark, former foreign affairs minister Lloyd Axworthy, former UN ambassador Stephen Lewis, actor Donald Sutherland and author Naomi Klein.

Live streams go down across Cox radio & TV stations in apparent ransomware attack (The Record)

Live streams for radio and TV stations owned by the Cox Media Group, one of the largest media conglomerates in the US, have gone down earlier today in what multiple sources have described as a ransomware attack.

The incident took place earlier this morning and impacted the internal networks and live streaming capabilities for Cox media properties, such as web streams and mobile apps. Official websites, telephone lines, and normal programming remained running but some live programming could not go on air as scheduled.

“This morning we were told to shut down everything and log out our emails to ensure nothing spread. According to my friends at affiliate stations, we shut things down in time to be safe and should be back up and running soon,” a Cox employee shared in a private conversation earlier today.

Asheville Radio Museum reopens to public after months-long pandemic closure (WLOS)

The Asheville Radio Museum reopened to the public Saturday, June 5, following a months-long closure due to the pandemic.

The museum, located on the campus of A-B Tech, and closed in November to follow the campus’s COVID-19 protocol to protect students and staff.

Asheville Radio Museum boasts a premier collection of vintage radios with the goal to educate, demonstrate and fascinate visitors about the importance of the radio, which was named the second most important invention of the twentieth century on the Science Channel.

Saturday’s reopening was highlighted by the addition of newly-procured radios as well as refreshed displays throughout the museum. Continue reading…

Aluminium-Ion battery development (Southgate ARC)

The Graphene Manufacturing Group in Brisbane, Australia together with the University of Queensland have according to the GMG website developed a Graphene Aluminium-Ion Battery energy storage technology that has up to three times the capacity of a lithium-ion battery and can charge up to sixty times faster.

The battery was created by inserting aluminium atoms into perforations made in graphene planes.
The company claims that because the batteries lack an upper Ampere limit that would otherwise cause spontaneous overheating, the batteries are also safer. The stable base materials also facilitate their recycling later.

The company hopes to bring these cells to market by the end of 2021 or early 2022

Radio Amateur’s Vintage Home Movie Film Sheds Light on Hindenburg Disaster (ARRL News)

Vintage home movie film provided by New Jersey radio amateur Bob Schenck, N2OO, was the highlight of a PBS documentary about the Hindenburg disaster. The film, shot by his uncle Harold Schenck, may provide clues as to what initiated the disastrous 1937 fire that destroyed the airship Hindenburg and claimed 35 lives as the German zeppelin was landing at Lakehurst, New Jersey. Harold Schenck tried to interest government investigators in his film, shot from a different angle than newsreel footage that begins only after the fire was well under way, but it was largely overlooked. “Nobody ever asked for it,” Bob Schenck explains in the documentary.

The Schenck film is the highlight of a PBS “NOVA” documentary, Hindenburg: The New Evidence, that investigates the issue in considerable depth in an effort to unlock the secrets of the cold case. The program aired on May 19 and remains available for streaming.

“My dad had bought this nifty Kodak camera — a wind-up movie camera, 8 millimeters — and he couldn’t come [to the Hindenburg landing] because he worked,” Bob Schenck recounted during the documentary. “So, he asked my uncle and my mom if they would take some shots and see the Hindenburg land.”

Bob Schenck approached Dan Grossman, an expert on airships, including Hindenburg, in 2012 during a commemoration of the disaster that forever memorialized radio reporter Herbert Morrison’s plaintive on-air reaction, “Oh, the humanity!” The NOVA documentary not only shares Schenck’s footage, which provided new clues to re-examine the cause of the explosion. The documentary also reviews scientific experiments that helped investigators come to a fresh understanding of what set off the fire. [Continue reading…]

Will chip shortage hit ham radios ? (Southgate ARC)

Glenn O’Donnell K3PP of Forrester Research notes the chip shortage may have a more serious impact than first thought and gives Amateur Radio rigs as an example of what might be affected

Self-described as a “ham radio nut,” O’Donnell discussed one of his hobbies to explain how the sway of tech titans could impact smaller companies as industries compete for limited resources.

“In this hobby, the newer radio “toys” are advanced technology, but the hottest radio might sell 5,000 units per year. If Apple wants 100 million chips, but the little ham radio company wants 5,000, Apple wins!” O’Donnell said.

NPR at 50: A Highly Selective History (Washington Post)

The network’s half-century evolution from an audio experiment to a media powerhouse

Today NPR is one of Washington’s most familiar and influential media companies, operating out of a gleaming, ultramodern broadcast facility on North Capitol Street. Its radio programs, online content, and podcasts reach millions of people around the world. But when it launched 50 years ago, in April 1971, National Public Radio was a decidedly scrappy enterprise.

How did a modest radio project from a bunch of audio idealists evolve into the multimedia behemoth that we now spend countless hours listening to? To celebrate NPR’s anniversary, we’ve put together a look at its history and transformation. Please note: If you would like to imagine the whole thing being read to you in the voices of Nina Totenberg and Robert Siegel, we won’t object. Click here to read the full article…

Radio Waves: The Woodpecker, Gutter Antenna, Air Travel With Radios, and “A Spy in Every Embassy”

The Russian Woodpecker: Official Bird Of The Cold War Nests In Giant Antenna (Hackaday)

On July 4th, 1976, as Americans celebrated the country’s bicentennial with beer and bottle rockets, a strong signal began disrupting shortwave, maritime, aeronautical, and telecommunications signals all over the world. The signal was a rapid 10 Hz tapping that sounded like a woodpecker or a helicopter thup-thupping on the roof. It had a wide bandwidth of 40 kHz and sometimes exceeded 10 MW.

This was during the Cold War, and plenty of people rushed to the conclusion that it was some sort of Soviet mind control scheme or weather control experiment. But amateur radio operators traced the mysterious signal to an over-the-horizon radar antenna near Chernobyl, Ukraine (then part of the USSR) and they named it the Russian Woodpecker. Here’s a clip of the sound.

The frequency-hopping Woodpecker signal was so strong that it made communication impossible on certain channels and could even be heard across telephone lines when conditions were right. Several countries filed official complaints with the USSR through the UN, but there was no stopping the Russian Woodpecker. Russia wouldn’t even own up to the signal’s existence, which has since been traced to an immense antenna structure that is nearly half a mile long and at 490 feet, stands slightly taller than the Great Pyramid at Giza.[]

Air Travel With Amateur Ham Radio Q&A (Ham Radio Crash Course)

A Spy in Every Embassy (Southgate ARC)

‘The intelligence coup of the century’. The extraordinary story of the longest running and most successful secret intelligence operation of the 20th Century.

For more than half a century, governments all over the world trusted a single company, Swiss-based Crypto AG, to keep the communications of their spies, soldiers and diplomats secret. But what none of its customers ever knew was that Crypto AG was owned for over 20 Cold War years by the CIA in partnership with the BND, the German Intelligence Service. The machines that many customers bought had deliberately weakened security – a window through which the CIA and BND could read the diplomatic traffic between their embassies, their trade negotiators and their own spies.

The BND sold out its share in 1993 for a tidy profit while the CIA continued until the company was broken up in 2018.

Crypto AG’s own secret was only cracked last year in a combined investigation by German ZDF television, Swiss SRF and the Washington Post following the discovery of a secret history, Operation Rubicon, that had been assembled by some of the operatives who had been involved in the deception.

A Spy in Every Embassy is the story of the story, presented by German intelligence journalist Peter F Muller, who produced last year’s television programme for ZDF, and British journalist David Ridd.

It gives the chronology of the manoeuvrings, arguments, successes and deceptions of the partnership that remained secret for a quarter of a century. Its revelations offer a new perspective on some of the landmark events of those decades – the Falklands War, the US bombing of Libya from British airfields, the negotiations that lead to the Camp David Accords and the Iranian Hostage crisis, as well as the daily churn of intelligence information from around the world about both friends and opponents.

The programme considers the collateral damage of deception on a grand scale. Most employees of Crypto AG knew nothing of the built-in weaknesses of the machinery they were building or trying to sell to governments in some very dangerous parts of the world.

Radio Waves: More RCI Services Come To An End, Pirate Radio Sound Tour, Shortwave Guitar Pedal, and Voyager 1 Detects Plasma “Hum”

Radio Waves:  Stories Making Waves in the World of Radio

RCI English section: goodbye (Radio Canada International)

Canada’s international broadcast service from the English language team of Radio Canada International has come to an end.

RCI, (originally the International Service, CBC-IS) was initially created towards the end of the Second World War. The purpose was to broadcast news and information from home via shortwave to Canadian military personnel fighting in Europe. It also began providing reliable news and information to recently liberated countries and to Germans still in the war.

That reliable news and information was considered of great value during the subsequent Cold War years, as several more languages were added to the service such as Russian, Ukrainian, Czech, Hungarian and Polish. Other languages sections included as Brazilian Portuguese and Japanese. With 14 language sections in 1990, and some 200 staff, the full English and French newsroom provided news of interest and importance for each language section specifically targeted to each of the various broadcast regions around the world.

Following a major budget cut of some 80 per cent in 2012, the shortwave and satellite service was terminated along with the majority of staff including the newsroom and some language sections. In recent years, only Chinese (Mandarin), Arabic, and Spanish remained along with English and French. RCI was transformed into a much smaller internet-based operation consisting of three people per language section.

In December 2020, the domestic public broadcaster CBC / Radio-Canada announced that the English and French sections of RCI would close for good in May. In their place curated stories from the domestic English and French public broadcaster will be provided.

A manager will now oversee the staff of eight who will adapt curated stories from the CBC and Radio-Canada into Mandarin, Arabic, and Spanish, along with Punjabi and Tagalog.

An effort was and is being made by the RCI Action Committee to preserve and even expand the service which has garnered great support from a former prime minister, former diplomats and many academics, but the end date has come. This is the last entry by the RCI English section.

From the English Section consisting of Lynn, Marc, and Levon, faithful and long-time popular replacement Terry Haig, and recently also Vincenzo Morello, and the many others over the all those years, we thank you for having shared our stories over these many years.[]


The Pirate Radio Capital: A sound tour with David Goren, radio producer and audio archivist (CRJ.org)

In 2018, David Goren, a radio producer and audio archivist, created the Brooklyn Pirate Radio Sound Map to collect the sounds of dozens of pirated broadcasts from across the borough. Pirate stations earn their name by hitching a ride on already licensed radio frequencies that typically cost commercial stations millions of dollars to acquire and set up. Nowhere in the country are there more pirate radio stations than in New York, where they provide a vital service to immigrant populations.

Goren estimates that New York has about a hundred pirate stations, transmitting from rooftops and attics to listeners seeking news from around the city and back home, as well as

entertainment and religious programming. The broadcasts bypass socioeconomic barriers and provide a means to seize control of the flow of information. But they are now at risk of extinction: Before Donald Trump left the White House, he signed the Pirate Act, which increased the authority of the Federal Communications Commission to fight pirate operations through mandatory sweeps in cities with high concentrations of pirate radio use. Pirate stations today face fines of up to two million dollars. “The people running these stations, they don’t have two million dollars,” Goren said. Broadcasters that don’t make it onto his sound map could be lost forever.

In the emptiness of space, Voyager 1 detects plasma ‘hum’ (Cornell.edu)

Voyager 1 – one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space – still works and zooms toward infinity.

As the craft toils, it has long since zipped past the edge of the solar system through the heliopause – the solar system’s border with interstellar space – into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves), according to Cornell-led research published May 10 in Nature Astronomy.

Examining data slowly sent back from more than 14 billion miles away, Stella Koch Ocker, a Cornell doctoral student in astronomy, has uncovered the emission. “It’s very faint and monotone, because it is in a narrow frequency bandwidth,” Ocker said. “We’re detecting the faint, persistent hum of interstellar gas.”

This work allows scientists to understand how the interstellar medium interacts with the solar wind, Ocker said, and how the protective bubble of the solar system’s heliosphere is shaped and modified by the interstellar environment.

Launched in September 1977, the Voyager 1 spacecraft flew by Jupiter in 1979 and then Saturn in late 1980. Travelling at about 38,000 mph, Voyager 1 crossed the heliopause in August 2012.

After entering interstellar space, the spacecraft’s Plasma Wave System detected perturbations in the gas. But, in between those eruptions – caused by our own roiling sun – researchers have uncovered a steady, persistent signature produced by the tenuous near-vacuum of space.

“The interstellar medium is like a quiet or gentle rain,” said senior author James Cordes, the George Feldstein Professor of Astronomy (A&S). “In the case of a solar outburst, it’s like detecting a lightning burst in a thunderstorm and then it’s back to a gentle rain.”

Ocker believes there is more low-level activity in the interstellar gas than scientists had previously thought, which allows researchers to track the spatial distribution of plasma – that is, when it’s not being perturbed by solar flares.[]

New Solar Radio Is an Emergency Kit too (Radio World)

Solar-powered portable radios that put audio quality second are nothing new. But a solar-powered portable radio that sounds as good as a non-solar high-fidelity radio: This is worth talking about.

The new CCRadio Solar from C.Crane fits this double-barreled description. With its generous top-mounted solar panel (3.75 by 1.5 inches) plus back-mounted generator crank for recharging its Lithium-Ion battery pack, this is a radio for blackouts and other emergency situations.

After an initial conditioning charge-up of the Lithium-Ion battery from a 5V DC adaptor, just leave it in a sunny window, and the radio is always ready to go.

In non-emergency situations, the CCRadio Solar can be powered with three AA batteries or a 5V DC charger plugged into its micro-USB port.[]

Congress Seeks to Designate National Amateur Radio Operators Day (In Compliance)

The U.S. Congress is reportedly taking steps to officially recognize the important contributions made by amateur radio operators.

According to an article on the website of the ARRL, Congresswoman Debbie Lesko (AZ) has introduced a bipartisan resolution to designate April 18, 2022 as National Amateur Radio Operators Day. April 18th is the anniversary of the founding of the International Amateur Radio Union (IARU) which was established in 1925.[]

An Inside Job (IEEE Spectrum)

YOUR GRANDPARENTS’ ancient transistor radio might still turn on and tune in to stations broadcasting conventional AM or FM signals. But in this Internet age, a blizzard of content is available from sources accessible only via the Web. What’s more, instead of speakers that flood a room with sound, we’ve grown accustomed to personal listening using earbuds and headphones. Now engineers like Guillaume Alday, founder of Les Doyens in Bordeaux, France, have come to the radio’s rescue. Alday keeps old-school radios from slipping into obsolescence by retrofitting their innards with components that transform them into Wi-Fi- and Bluetooth- enabled devices.[…]

Bletchley Park: WW2 secret agent’s messages remembered (Southgate ARC)

The BBC reports the first message sent back to Britain by a ‘trailblazing’ special agent in World War Two has been commemorated, 80 years on, by radio amateurs using GB1SOE

Georges Begue, of the Special Operations Executive, was parachuted into occupied France in 1941 to set up wireless communications with the UK.

Amateur radio enthusiasts have marked his achievement by sending and receiving messages at Bletchley Park.

On Thursday and Friday May 6-7, Milton Keynes Amateur Radio Society is using replica equipment to transmit Morse code messages from the National Museum of Computing at Bletchley to fellow radio enthusiasts in central France, stationed less than a mile from where Begue landed.

Turkey marks 94th anniversary of its first radio broadcasting (Hurriyet Daily News)

Turkey celebrated Radio Day on the 94th anniversary of the start of radio broadcasting in the country.

“Radio broadcasting in Turkey started 94 years ago today with the first announcement,” Turkey’s Presidential Communication Director Fahrettin Altun wrote on Twitter.

“Our radios, which have been working devotedly to bring our beloved nation together with the truth for years, have become one of the most important parts of our lives,” he added.

Altun also congratulated all radio workers on Radio Day too.

Türkiye Radyolar? (Radios of Turkey) has started first radio test broadcasts in 1926, with a studio built in Istanbul. The first radio broadcast in the country, however, began on May 6, 1927.[]

Internet radio with real buttons using Stream Deck (Bjørn Erling Fløtten)

How I used a Stream Deck Mini from Elgato in order to give my mother-in-law a super easy Internet radio experience.

By Bjørn Erling Fløtten, Trondheim, Norway. April 2021.

See also comments on Hacker News

Background

My mother-in-law is from Poland. When she stays in Norway in order to help us with babysitting she misses Polish radio. In principle this is easily accessible through the Internet now from all kind of devices.

BUT, my mother-in-law is not PC-literate, nor does she use a so called ‘smart’-phone. With my long experience in teaching people far younger than her simple mouse and keyboard techniques, I knew that operating Windows and finding Internet radio stations on her own would just be too cumbersome. I therefore had to create a super simple setup for her, and my hacker mind started to think.

(I did of course consider special purpose Internet radios. They should in theory be quite simple to operate, but they all have som kind of quirks that I did not like. And besides, constructing something of your own is of course always more satisfying.)

I want Real Buttons!

What I really wanted was big buttons with tactile feedback. I had earlier experienced with some Behringer products (sound mixing board) in order to demonstrate mathematical functions. The idea then was to use turning knobs and sliders in order to see how changing parameters changed the outcome of the function, especially graphs in 2D and 3D.

I thought this would be useful also for an Internet radio, but then I remembered having read about the Optimus Maximus keyboard (keyboard with programmable led icons on each key), and I thought such a product would be even better. This search led to Elgato and their Stream Deck Mini. This has 6 buttons, just enough for a radio. I might have preferred the bigger version with 15 buttons but their products are ridiculously expensive, so I had to be content with just 6 buttons.

In addition to the Stream Deck Mini my son donated his old school laptop with Windows 10 installed. It was a cheap ThinkPad L-series which, although 3 years old and somewhat battered from daily use to and from school, was quite capable of streaming some audio from the Internet. My son created a guest account in Windows 10 with auto login. He set ‘Fn lock’ as default, meaning that keys F1, F2 and F3 was volume off, down, up without having to press Fn. We also found a pair of speakers lying around in the house.

No programming necessary *

(* But understanding of HTML, URLs and Windows command line arguments is a requisite.)

Initially I thought I would make a Windows application for controlling which radio streams to play. But it turned out that Elgato’s accompanying software was quite capable by itself.

I assigned five of the six available buttons to launch the standard web browser (Google Chrome in this case) with a corresponding streaming URL (radio channel).

Annual Armed Forces Day Cross-Band Test set for May 7 – 8 (Southgate ARC)

The US Department of Defense will host this year’s Armed Forces Day (AFD) Cross-Band Test, Friday and Saturday, May 7 – 8, in recognition of Armed Forces Day on May 15. The event is open to all radio amateurs.

For more than 50 years, military and amateur stations have taken part in this exercise, designed to include amateur radio and government radio operators alike.

The AFD Cross-Band Test is a unique opportunity to test two-way communications between military and amateur radio stations, as authorized under FCC Part 97 rules. These tests provide opportunities and challenges for radio operators to demonstrate individual technical skills in a tightly controlled exercise in which military stations will transmit on selected military frequencies and will announce the specific amateur radio frequencies being monitored.

The schedule of military/government stations taking part in the Armed Forces Day Cross-Band Test and information on the AFD message is available on the MARS website.

RAC Canadian Portable Operations Challenge Award (Southgate ARC)

The RAC Challenge Award: An Overview
Radio Amateurs of Canada is pleased to present a new Canadian Portable Operations Challenge Award for RAC members.

The objective of the new “RAC Challenge Award” is to recognize and encourage portable operations by RAC members from locations throughout Canada.

The new program will begin on Canada Day, July 1, 2021 and we hope it will become an annual event for RAC members.

Note: the following information is tentative as the new Awards program is still being organized so please stay tuned to this webpage for future updates.

Portable Operations
Portable operations are those in which Amateurs take their equipment, antennas and power supply to a location away from their home station to operate. This includes mobile stations, backpackers, DXpeditions and participation in events such as those described below:

Parks On The Air (POTA), a worldwide program of park activations – https://parksontheair.com/
Quebec Parks On The Air (QcPOTA) April 1 to December 31
Field Day: June 26-27
There are several other programs that celebrate portable operations including Summits on the Air (SOTA), Islands on the Air (IOTA) and the International Lighthouses and Lightships Weekend.

Features of the “RAC Challenge”
The new “RAC Challenge” will recognize all portable operations in which RAC members participate and will have similar features as a contest. Amateur Radio contests in VHF, UHF and the Microwave bands all have categories for “Rovers” – who move from grid square to grid square and “Backpackers” – who seek out hilltops from which to operate with highly portable equipment and antennas.

For many satellite operators, making contact with as many grid squares as possible is a mark of success. Some of those operators go on satellite DXpeditions to activate rare grids or operate from the intersections of grids to offer multiple grids with a single contact. In addition to being fun, these activities provide an opportunity for Amateurs to experience what is required to set up and operate under challenging conditions – valuable experience for emergency preparedness.

Sinclair Launches ATSC 3.0 Test Site; Partners With Fraunhofer On Mondiale Service Integration (ATSC)

HUNT VALLEY, Md.—Mark Aitken, senior vice president of advanced technology at the Sinclair Broadcast Group, flipped the switch on a 100w transmitter to begin broadcasting ATSC 3.0 from atop the station group’s corporate headquarters here with the express purpose of testing reception on small devices like its MarkONE 3.0-enabled smartphone and, in particular, integration of Digital Radio Mondiale (DRM) in its broadcast app.

The launch comes on the same day Sinclair and German technology research institute Fraunhofer IIS jointly announced they are working together to bring audio services using the DRM standard to ATSC 3.0. (Earlier this year, Sinclair rolled out 3.0 simulcasts of its Seattle radio stations with its DRM-based broadcast app.)

“We are actually building the DRM radio service into the [3.0] broadcast app environment,” says Aitken. “That means those [DRM] services will be carried in band and transported just like HEVC [high efficiency video coding] and [Dolby] AC-4.”[]

Clear Frequencies Requested for Net Providing 24/7 Coverage of St Vincent Volcanic Eruption (RAC Newsletter)

For immediate release:
April 20, 2021 –

The Caribbean Emergency and Weather Net (CEWN) has been providing round-the-clock coverage during the La Soufriere volcanic eruption on the island of Saint Vincent and the Grenadines.

Several neighbouring islands are also being affected by the disaster.

When responding to disasters and emergencies such as this, the CEWN utilizes 3.815 MHz LSB and 7.188 MHz LSB. CEWN is requesting that Radio Amateurs not involved in the volcano response to keep these frequencies clear.

Geomagnetic storm warning (Spaceweather.com via Southgate ARC)

A CME is heading for Earth and it could spark a geomagnetic storm when it arrives on April 25th.

NOAA forecasters say moderately strong G2-class storms are possible, which means auroras could dip into northern-tier US states from Maine to Washington.
