Is radio in a second golden age? Here’s what the first looked like. (MSN / Washington Post)

On. Oct. 30, 1938, America was rocked by shocking news: Aliens had been spotted crash-landing outside Grover’s Mill, N.J. Additional sightings were soon made across the Northeast, including reports of Martians unleashing poisonous gas on Manhattan and burning onlookers alive with ray guns. Periodically, the breathless news reports would be reduced to static.

Listeners reacted in real time; many of them flooded the streets wearing gas masks and wet towels over their faces. Stores were raided, bridges and expressways were inundated with traffic, and pregnant women reportedly went into early labor.

Of course, the alien invasion never actually happened. The news bulletins were part of a live Halloween program a young producer and a cast of talented actors were presenting over the radio. The producer was 23-year-old Orson Welles, and the name of the episode was “War of the Worlds.” The H.G. Wells-adapted story had been produced for radio as part of Welles’s regular Sunday night broadcast, “The Mercury Theater on the Air” — a program that had hitherto been largely ignored, as it was up against a wildly popular variety show starring comedians Edgar Bergen and Charlie McCarthy.

Only this Sunday was different, as millions of Americans who had tuned in to listen to Bergen and McCarthy changed their dials when the duo introduced a guest opera singer. “No one was in the mood for opera that night, and much of the country stumbled onto Welles’s broadcast by mistake, not knowing the news bulletins they heard were part of a radio drama,” explained Carl Amari, a syndicated radio host and the founder of Radio Spirits, a large distributor of classic radio programs.

The Kremlin tries to stifle Radio Free Europe — and its audience surges (Washington Post)

As the U.S.-funded broadcaster is forced to shut most of its Russian operations, its Web traffic indicates that Russian people are eagerly consuming its stories

Radio Free Europe, the U.S.-funded operation that got its start by piping American-flavored news through the Iron Curtain in 1950, could see big trouble brewing for its Russian operation in recent years.

The Kremlin kept putting the screws to its Russian-language broadcasts, throwing up ever more regulatory hurdles. But it was in late 2020 that the hammer really came down. The “media regulator” demanded that every broadcast, digital story and video carry an intrusive disclaimer at the top stating that what followed was the product of a foreign agent.

“Basically, it was like telling our audience to go away,” said Jamie Fly, the CEO of Radio Free Europe/Radio Liberty, as the organization has been known since a 1976 merger.

That labeling would interfere with the private nonprofit’s mission at a core level. So, Fly told me, “we refused to comply.” [Continue reading…note that this content might be behind a paywall for some readers.]

New radio station helps Ukrainian refugees adapt in Prague (AP)

PRAGUE (AP) — This is Radio Ukraine calling.

A new Prague-based internet radio station has started to broadcast news, information and music tailored to the day-to-day concerns of some 300,000 Ukrainian refugees who have arrived in the Czech Republic since Russia launched its military assault against Ukraine.

In a studio at the heart of the Czech capital, radio veterans work together with absolute beginners to provide the refugees with what they need to know to settle as smoothly as possible in a new country. Continue reading

Voice heard ’round the world: Voice of America museum near Cincinnati a historical marvel (The Columbus Dispatch)

WEST CHESTER, Ohio — Imagine, if you will, a voice so strong that it shakes the very foundations of global tyranny.

In the early days of World War II, a group of Americans, including President Franklin Roosevelt, actor and director John Houseman and Cincinnati entrepreneur Powell Crosley Jr. imagined such a voice, one that could counter Nazi propaganda in Hitler’s own backyard.

They named it The Voice of America.

Today, the National Voice of America Museum of Broadcasting, 8070 Tylersville Road, occupies the site from which the service beamed its message around the world for 50 years beginning in 1944, recounting its history and remembering the people, especially Crosley, who made it possible.

100th Anniversary Celebration of the First Trans-Atlantic Radio
Transmission of a Message by Amateur Radio (1BCG.org)

Saturday, December 11, 2021

On a cold winter night on December 11, 1921, members of the Radio Club of America were able to send the first amateur radio message from a small shack in Greenwich, CT to be received by American Paul Godley in Ardrossan, Scotland. This transatlantic test proved the value of shorter wavelengths – long considered worthless to long distance communications and through their success ushered in the age of global shortwave radio communications. The 1921 message was sent one-way. Acknowledgment of Paul Godley’s reception of 1BCG’s massage was sent back to the US via the Marconi high power radio transmitter in Wales.

The Antique Wireless Association, in association with the Vintage Radio and communications Museum of Connecticut (VRCMCT) in Windsor, CT, the Radio Club of America, the American Radio Relay League, and the Radio Society of Great Britain, participated in the 100th Anniversary special events held Saturday, December 11, 2021.

For the 75 th anniversary celebration of the 1BCG accomplishment in 1996, AWA members Bob and Mike Raide constructed a replica of the 1921 transmitter. For this 100th celebration, AWA Museum Staff restored the replica. The VRCMCT in Windsor CT has graciously offered to host AWA operation of the replica transmitter during the evening of December 11th. The 1BCG replica transmitter was placed on public display at the VRCMCT Museum during the day of Saturday December 11, 2021. [Continue reading the full report at the 1BCG website…]

Celebrations to mark the BBC’s Centenary began at midday today (1/1/2022) via shortwave radio (Southgate ARC)

BBC Radio 4 announcer/newsreader, Jim Lee, launched special event amateur radio station GB100BBC, from the BBC’s Broadcasting House, in London, at exactly midday.

Listen to the broadcast:
GB100BBC launches 1st Jan 2022
With thanks to the London BBC Radio Group

Within minutes amateur radio stations around the UK and throughout Europe were clamouring to contact the special BBC station and secure a prized entry in the logbook.

The London BBC Radio Group was granted an extended special event radio licence by the regulator OFCOM, to operate the station throughout 2022.

The amateur radio activity is one of many events organised to celebrate 100 years of the BBC, which began broadcasting from Savoy Hill in 1922 as the British Broadcasting Company, moving to the iconic Broadcasting House in 1932, gaining a Royal Charter as the British Broadcasting Corporation.

The London BBC Radio Group has a growing membership which includes engineers, journalists, producers and on-air talent in both TV and Radio. The group is independent but hosted and supported by the Corporation.

The group was launched in 2017 by a handful of radio enthusiasts to revive a long and rich history of amateur radio at the BBC dating back to the Second World War.

The ‘radio shack’ at the BBC’s headquarters, Broadcasting House in central London, was officially opened by the then Director General, Lord Tony Hall, with an over-the-air message of congratulations. Lord Hall was subsequently bestowed Honorary membership of the club. [Click here to read at the Southgate ARC…]

Czech radio switches off MW and LW as 2022 starts (Mike Terry via the Southgate ARC)

Prague (dpa) – Radio reception on medium wave (MW) and long wave (LW) has been history in many parts of Europe for years.

Now, in the Czech Republic, at least the public broadcaster will stop transmitting on MW and LW as the new year starts on Saturday.

The powerful transmitters on the frequencies 270, 639 and 954 kilohertz could also be received in large parts of Germany.

The reason given for the move was the widespread availability of terrestrial digital radio DAB+ and the high costs of broadcasting.

Those still listening using medium waves were to be persuaded to switch with a campaign. The radio station Cesky Rozhlas set up a telephone hotline to answer questions.

It was not known at first whether the transmitters would be retained or used for other purposes.

The antenna of the medium-wave transmitter Liblice B east of Prague is considered the highest structure in the Czech Republic, with a height of 355 metres.

Impuls, the most-listened to private radio station, wants to remain faithful to medium wave for the time being. It broadcasts its second programme, with pop and country music, on analogue transmission.

Alike, but Not Alike: Broadcast vs. Ham Radio (Radio World)

Experience in amateur radio can be a boon to the radio engineer

Starting in the 1920s and through the ’60s, almost every broadcast engineer was a licensed amateur radio operator. That has changed a bit, but the importance of being a ham has not.

Both environments involve getting an RF signal from Point A to Point B. But it is interesting to note that radio broadcast and amateur radio are similar and yet so different.

For those who don’t know much about ham radio, I’ll tell you that communicating locally or internationally, via licensed amateur radio, can be a fascinating and challenging hobby. There are about 700,000 hams in the U.S. and an equal number worldwide.

Physics

Broadcast and amateur radio operate under the same laws of science. Transmitters, transmission lines, antennas and receivers make up an RF path to convey a message.

Broadcast engineers know that signal propagation on AM and FM bands is dramatically different. It is because our FM band is roughly 100 times the frequency and 1/100th the RF wavelength of that on the AM band. Engineers also know that 950 MHz STL signals are line-of-sight and roughly a 10-times jump in frequency from FM broadcast frequencies. Each band has its own challenges in getting a useable signal through. [Continue reading…]

A Canadian opens up about her secret wartime work — eavesdropping on Japan (CBC)

Retired sergeant remembers what it was like on the ‘front line of the radio war’

At age 97, Marjorie Stetson has never told anyone her secret code number — until now.

That’s the identity code — 225 — that she typed on every page of her highly classified work for the Canadian Armed Forces during the Second World War.

The retired sergeant’s wartime work was so covert, she said, she had to sign 15 separate copies of Canada’s Official Secrets Act.

“Nobody knew where I worked,” Stetson told CBC News from her home in Massachusetts ahead of Remembrance Day. “Nobody knew what we did. Even my parents never knew what I did in the service.”

Her husband, an American sailor she met at a celebration marking the end of the war, passed away a decade ago. She never told him what she really did during the war.

Today, Stetson herself is only now learning about the true scope of her role and the significance of all those sheets of white paper she filled with encrypted messages from Japan. [Continue reading…]

Czech Republic: MW Switch-Off by 2021 (Radio Reporter)

Czech public radio ‘?eský Rozhlas‘ is stepping up its information campaign for listeners receiving mediumwave programmes, ahead of the planned switch-off of transmitters by the end of 2021. Since 1 November, more announcements have been broadcast to warn users and a call centre has been set up to explain the possible listening alternatives (from FM to DAB). In the run-up to Christmas, public radio will launch an intensive advertising campaign in the print media and online magazines on 22 November to promote the purchase of digital DAB receivers to replace analogue radio.

The impact of photovoltaics (Southgate ARC)

Seamus Ei8EP reports on the IARU Region 1 website that the 358 page Final Report on the Study on the evaluation of the Electromagnetic Compatibility Directive has now been published.

It is publicly available, free of charge, from the Publications Office of the European Union. The Political Relations Committee of the IARU Region 1 responded recently to a European Commission Roadmap on the environmental impact of photovoltaics.

The radio spectrum is an important finite natural resource which must be protected. While PV technology of itself is to be welcomed, the IARU submission pointed out the inherent problems of non-compliant installations, particularly the installation or retro-fitting of optimisers which can produce significant spectrum pollution for very limited efficiency increase.

As Disasters Roil Earth, A New Sun Cycle Promises Calmer Weather — In Space (NPR)

Giant flares and eruptions from the sun can cause space weather, and stormy space weather can interfere with everything from satellites to the electrical grid to airplane communications. Now, though, there’s good news for people who monitor the phenomenon — the sun has passed from one of its 11-year activity cycles into another, and scientists predict that the new cycle should be just about as calm as the last.

That doesn’t mean, however, zero risk of extreme weather events. Even during the last, relatively weak solar cycle, drama on the sun triggered occasional weirdness on Earth like radio blackouts, disruptions in air traffic control, power outages — and even beautiful aurorae seen as far south as Alabama.

Over each solar cycle, the roiling sun moves from a relatively quiet period through a much more active one. Researchers monitor all this activity by keeping an eye on the number of sunspots, temporary dark patches on the sun’s surface. These spots are associated with solar activity like giant explosions that send light, energy, and solar material into space.

Counting of sunspots goes back centuries, and the list of numbered solar cycles tracked by scientists starts with one that began in 1755 and ended in 1766. On average, cycles last about 11 years.

Based on recent sunspot data, researchers can now say that so-called “Solar Cycle 24” came to an end in December of 2019. Solar Cycle 25 has officially begun, with the number of sun spots slowly but steadily increasing.[]

WWJ in Detroit: A 2020 Centennial Station (Radio World)

Iconic AM station just celebrated the 100th anniversary of its first broadcast

It was shortly after World War I that Clarence Thompson, a partner of Lee de Forest, formed a new company Radio News & Music Inc. in New York. His goal was to encourage newspapers to broadcast their news reports by wireless, using de Forest transmitters.

The franchise offer — available to only one newspaper in each city — offered the rental of a de Forest 50-watt transmitter and accessories for $750. Just one newspaper signed up for the deal; it was the Detroit News, led by publisher William E. Scripps.

He had been interested in wireless since investing in Detroit experimenter Thomas E. Clark’s wireless company in 1904. Scripp’s son, William J. “Little Bill,” was an active ham radio operator, operating a station in the Scripps home.

People Might Laugh

Scripp proposed accepting the Radio News & Music offer and building a Detroit News radio station in 1919, but he met resistance from his board of directors. It was not until March of 1920 that he was given the go-ahead to sign a contract.

The de Forest transmitter was shipped to Detroit on May 28, 1920, but was lost in transit; a second transmitter was constructed and sent on July 15. This delayed the installation of the station until August.[]

Czech Radio has expanded DAB + coverage to 95 percent of the population and announced the switch-off of medium waves (Digitalni Radio)

NOTE: This is a machine translation of the original post in Czech.

Czech Radio has entered another, important phase of radio digitization. To date, the ?Ro DAB + multiplex signal has reached 95% population coverage. Ten new transmitters were launched in Bohemia and Moravia. You can find a detailed description of them below.

DAB + technology is becoming a common distribution channel for Czech Radio, which will be placed on the same level as analogue FM / FM broadcasting. All marketing activities will already include the “DAB + More Radio” logo. ?eské Radiokomunikace is planning to start certification of receivers next year in order to protect customers and facilitate orientation in the range for them and retailers.

According to the CEO of Czech Radio, René Zavoral, the public service media is proceeding in accordance with a long-term strategic plan. The head of communication and press spokesman Ji?í Hošna describes the step as a turning point that can affect the direction of the entire radio market.[]

UK amateur radio exam report released (Southgate ARC)

The RSGB Examinations Standards Committee (ESC) report covering 2019 is now available for anyone to download

The report contains statistics for the both the RSGB amateur radio exams and the Air Cadets Organisation (ACO) exam which Ofcom considers to be equivalent to the RSGB Foundation.

Ofcom has been concerned about the participation of women in amateur radio and STEM disciplines. They requested the ESC to publish figures for the number of women taking the exams. Unfortunately the results are disappointing with only 9.9% of all exams being taken by women.

Hear My Voice: Radio’s role in Hitler’s annexation of the Sudetenland

In January, when I first heard about David Vaughan’s book Hear My Voice, I knew then and there I would have to read it. So I picked up a copy on Amazon with the intention of doing so…well, soon.

However, I’ve got quite a number of books in my to-be-read stack at the moment, so Hear My Voice lay in wait on my bookshelf until this past Sunday, when I decided to read the first chapter––just to get a taste of it.

Although I had a very busy day in store––working on a home renovation and making several trips into town––nevertheless I struggled to pull it from the stack, and having rapidly consumed the first chapters, had a hard time putting the book down. By the day’s end, I found I had read the entire book.

While those who know me know I’m a bit of a WWII history buff, I only knew that Hitler’s seizure of the Czech Sudetenland was but a hint of what was to come. The history I’d read previously had provided a bit of insight into this crucial lead-up to the war, but not as Vaughan’s book does: in what feels like a first hand account, through the eyes of an interpreter and broadcaster. I was hooked.

Hear My Voice clearly indicates how transformative the medium of radio was in this era, and how deliberate and insidious Nazi propaganda became in the Sudetenland years before Czechoslovakia ever took notice.

All in all, it’s a great read. I think you’ll find Hear My Voice as intriguing as I did.
