Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Richard Cuff, Dennis Dura,

In 1924, a magazine ran a contest: “Who is to pay for broadcasting and how?” A century later, we’re still asking the same question (NiemanLab)

Radio Broadcast received close to a thousand entries to its contest — but ultimately rejected them all.

After yet another day reading about audio industry layoffs and show cancellations, or listening to podcasts about layoffs and show cancellations, I sometimes wonder, “With all this great audio being given away for free, who did we think was supposed to pay for it all?”

I find some consolation in the fact that that question is more than a century old. In the spring of 1924, Radio Broadcast posed it in a contest called “Who is to Pay for Broadcasting and How?”The monthly trade magazine offered a prize of $500 (more than $9,000 in today’s dollars) for “a workable plan which shall take into account the problems in present radio broadcasting and propose a practical solution.”

The need for such a contest more than 100 years ago is revealing enough, but the reaction of the judges to the prize-winning plan turned out to be even more so — and it says a lot about why business models for audio production and broadcast remain a struggle. [Continue reading…]

The Rich History of Ham Radio Culture (The MIT Press Reader)

Drawing on a wealth of personal accounts found in magazines, newsletters, and trade journals, historian Kristen Haring provides an inside look at ham radio culture and its impact on hobbyists’ lives.

Every night thousands of men retreat to radio stations elaborately outfitted in suburban basements or tucked into closets of city apartments to talk to local friends or to strangers on the other side of the world. They communicate by speaking into a microphone, tapping out Morse code on a telegraph key, or typing at the keyboard of a teletypewriter. In the Internet age, instantaneous, long-distance, person-to-person communication seems ordinary. But amateur radio operators have been completing such contacts since the 1910s. The hobbyists often called “hams” initially turned to radio for technical challenges and thrills. As the original form of wireless technology became more reliable and commonplace in the 1930s, ham radio continued as a leisure activity. Hams formed a community through the same general practices of other social groups. They set conditions for membership, established rules of conduct, taught values, and developed a specialized vocabulary known only to insiders. What made hams’ culture different was its basis in technology. In her book “Ham Radio’s Technical Culture,” excerpted below, historian of science and technology Kristen Haring draws on a wealth of personal accounts found in radio magazines and newsletters and from technical manuals, trade journals, and government documents to illustrate how ham radio culture rippled through hobbyists’ lives.

CarnationFM: A Decentralized Radio Playing Songs With Encrypted Hidden Messages (Coin Desk)

CarnationFM emerged from EthBerlin 2024 and won the award for Best Social Impact.

Berlin, Germany: A music-focused radio FM which allows songs to act as a transport vessel for hidden messages has emerged from EthBerlin 2024. CarnationFM was created by five hackers and a mentor as a defensive, decentralized and encrypted communication tool enabling private messaging that safeguards anonymity.

The project, which won the award for the Best Social Impact at EthBerlin 2024, is focused on creating real world use cases factoring in privacy in the aftermath of the Alexey Perstev verdict. Alexey Perstev, one of the co-founders of Tornado Cash, was sentenced to 64 months in prison in May.

The verdict rattled the decentralized community because it suggested that a coder could be held responsible for everything that happens using that code. Perstev was found guilty because his open-source mixer Tornado cash allowed North Korea’s infamous Lazarus group to launder millions in crypto. [Continue reading…]

Nation’s last Morse code station comes back to life on annual ‘Night of Nights’ in Point Reyes (The Mercury News)

KPH, established in Point Reyes and Bolinas in 1913, will exchange messages with Morse code enthusiasts around the world

On July 12, 1999, the nation’s final message in Morse code was sent out to sea from a remote Bay Area radio station. The end of an era, the room’s mood was mournful. Grizzled old men wept.

“We wish you fair winds and following seas,” it said, offering a seafarers’ traditional farewell in a staccato stream of dots and dashes. And then the station went silent.

But every July 12, the golden age of maritime radio comes back to life. [Continue reading…]

Navy researchers ask Envisioneering to support over-the-horizon radar that relies on HF radio signals (Military Aerospace Electronics)

Over-the-horizon radar typically uses HF radio signals at frequencies between 2 and 30 MHz to reach beyond the horizon in open-ocean areas.

WASHINGTON – U.S. Navy researchers needed to help develop a new prototype High Frequency (HF) over the horizon (OTH) radar system. They found a solution from Envisioneering Inc. in Alexandria, Va.

Officials of the Naval Research Laboratory (NRL) in Washington announced a $45.4 million contract to Envisioneering Inc. on Monday for design, development and integration of a mobile over-the-horizon radar (MOTHR).

Over-the-horizon radar typically uses HF radio signals at frequencies between 2 and 30 MHz to reach beyond the horizon in open-ocean areas. HF signals bounce off the ionosphere to achieve long distances and operate beyond the curvature of the Earth.

Envisioneering will work alongside the NRL research team to support key areas such as refinement of system requirements; system and subsystem design; mechanical analysis; specifying and procuring long-lead items; integration; testing; and signal processing. [Continue reading…]

Radio Waves: Switzerland to End Analog Radio, AM For Every Vehicle Act, AM v Safety, and Electromechanical Radio Transmitters

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Paul and Dennis Dura for the following tips:


Switzerland to end 2024 with an analog FM broadcast-killing bang (The Register)

Time to upgrade that receiver if you’re one of the few Swiss that still don’t have one able to receive DAB+ signals

Swiss radio listeners will soon have to toss out their old sets, as the country plans to end analog FM broadcasting on December 31, 2024, in favor of a total conversion to digital.

The move has been a long time coming in Switzerland, which has largely already transitioned to Digital Audio Broadcasting (DAB+, an evolution of standard DAB that was designed to address early issues). More than 99 percent of the country have access to a DAB+-compatible receiver and fewer than 10 percent of radio signals in the country still being broadcasted in analog FM, according to the Swiss Broadcasting Corporation.

AM Radio for Every Vehicle Act to Receive Minor Technical Update (Radio World)

There will be no substantive changes to the legislation

A bill in the House of Representatives that would mandate AM capability in new vehicles is about to be revised, according to a person familiar with the developments.

New information indicates that one of the original co-sponsors of the bill, Rep. Frank Pallone (D-N.J.), plans to introduce an amendment to the bill (H.R. 8449). Changes would only include minor technical updates.

The planned amendment to the AM Radio for Every Vehicle Act comes on the heels of last week’s last-minute cancellation of a planned vote by the House Energy and Commerce Committee, which could have advanced the legislation to the full House for a vote. [Continue reading…]

Would AM Mandate Force Carmakers to Scrap Safety Features?

Opponents play up the possibility that carmakers would have to choose

If Congress requires AM radio in new cars, vehicle manufacturers might have to drop safety features instead.

That’s the message from opponents of the proposed law in Congress. A guest commentary published by Automotive News restates the key points that opponents have been making since the legislation was introduced; but their blunt emphasis on a possible tradeoff with important safety features seems notable.

“To accommodate analog AM radio as a primary design requirement, certain carmakers may need to scrap advanced safety features, with engineers having to prioritize outdated technology over current or future safety innovations,” they wrote. [Continue reading…]

Did you know that 100 years ago there were electromechanical radio transmitters?

Many thanks to Paul who shared a link to this Mastodon thread discussing the technology behind the SAQ/Grimeton broadcast station: https://mastodon.social/@tubetime/110970146022678448

Here’s is a video (we’ve posted in the past) that gives even more detail about the design and operation:

“Music On The Move” explores portable audio technology developments over the decades

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

Last night on my bedside radio I heard on BBC World’s ‘The Forum’ a wonderful 49-minute piece about portable audio. Much of it covers the earliest portable electron tube radios and transistor radios, and their influences on society in different countries. Mediumwave, Shortwave and FM radios and stations are discussed, as well as evolving technologies. The societal impact of the Compact Cassette and digital audio players and recorders is also discussed. Probably all SWLing Post readers will find this worth listening to!

Cheers,

The Forum: Music On The Move

Released On: 22 Jun 2024

Many of us remember the first portable music device we owned: a transistor radio, a boombox, a Walkman or perhaps an iPod. We might even recall the songs we played on it. But we might be less aware of how profoundly audio technology developments from the 1950s to 2000s changed the ways in which we consume music and other audio outside of the home or concert venue. Transistor radios allowed outdoor sounds and noises to mix and compete with those coming over the airwaves, creating new auditory experiences; the cassette player gave the listener a cheap way of making and re-making their own playlists; and the advent of digital music players encouraged us to ‘own’ music recordings without possessing a physical copy of the audio.

Iszi Lawrence discusses the history of portable music with Dr. Annie Jamieson, Curator of Sound Technologies at Bradford’s National Science and Media Museum; American drummer and writer Damon Krukowski; Dr. Jahnavi Phalkey, science historian and Founding Director of Science Gallery Bengaluru, India; Karin Bijsterveld, Professor of Science, Technology and Modern Culture at Maastricht University; and World Service listeners.

“What connects the Finnish YLE station and Prague?”

Professionals at the station often had a background as radio amateurs or radio electricians. Photo from YLE’s archive.

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

Hi Thomas, a post on Reddit with a picture of radio stuff lead me to Google for its source.

It led me to this page https://yle.fi/a/3-11502533

My Finnish is not as good as Google’s, but even with its poor “auto” translation, the story can be fairly understood and bring to life the 1968 Soviet’s invasion to Prague from the YLE side.

That article was written in a book by an YLE broadcasting engineer for 40 years. A few pages of his book can be viewed here with more nice pictures.

As a child I do recall that event in the local news coverage and it was also immortalized few months later, in the Israeli music scene with an amazing song, very popular till today.

I’m sure many of SWL’ers can share some of their memories of that Soviet’s invasion to Prague in 1968.

Best regards, adi

Many thanks to SWLing Post contributor, Kris Partridge, who writes:

With the imminent approach, Thursday, June 6, 2024, of the 80th anniversary of D-Day, followed by operation Overlord.

Being both a radio amateur and in the broadcast industry , I have done a little research and find the two items, below, relating to D-Day and post-D-Day communications and broadcasters.

One, from the BBC Archives for a UK ‘view-point’

and Two, from RadioWorld for the US angle

But remember it was nearly a year away to VE-Day, so more research to be done on the effort of broadcasters to “bring the story home”

Also, one amateur radio related note: A SES (Special Event Station) with the callsign GB8ODD: https://g5fz.co.uk/up-coming-special-event-stations-by-the-lswc/

Being a WWII history buff, I really appreciate the links. Thanks, Kris!
