Morse Code is making a comeback! Children as young as FIVE are learning the once groundbreaking form of communication – spurred on by K-Pop bands who use it to leak hints about upcoming songs to fans (Daily Mail)

Despite being created 180 years ago and not being a requirement for amateur radio operators to learn since 1990, it has been kept alive by radio enthusiasts – and now more young people are getting involved.

A combination of pandemic lockdowns forcing youngsters to learn something new, and the use of Morse Code by popular K-Pop bands, has led to ‘a renaissance’ in teens wanting to learn the once groundbreaking form of communication.

From five-year-olds to 99-year-old war veterans, people all over the world are tapping in to communicate with others on the radio. [Continue reading…]

Ham radio tunes in to a new generation (The Times)

As he sits in a shed on the outskirts of Cambridge, Martin Atherton twists a radio dial and picks up a message being sent in Morse code. The audio dots and dashes, familiar from black-and-white war films, might seem to be relics of a past era.

But more than a century after it was first used, this mode of communication appears to be making a comeback. Since 2006 the number of amateur radio licences, which allow holders to send Morse and voice messages, has increased by almost 60 per cent, according to the Radio Society of Great Britain.

Last year the number of 13 to 44-year-olds viewing the society’s online tutorials, which cover topics such as “improving your Morse skills” and how to build your own equipment, more than tripled.

Allowing people to reach out to distant lands on a shoestring budget, the hobby could have been tailor-made for lockdown. The Netflix series Stranger Things, in which a “ham” radio set is used to contact another dimension, has also been linked to an increase in interest.

“Teenagers are picking it up, so are retirees,” said Atherton, 69, a member of the Cambridge University Wireless Society. [Continue reading…]

Pirate Radio (Twenty Thousand Hertz – The stories behind the world’s most recognizable and interesting sounds.)

In the 1960s, the BBC had a vise grip on British radio, and rarely played the pop and rock music that was all the rage. So a group of rebellious radio DJs decided to give the people what they wanted, and started broadcasting popular music from boats stationed in international waters. Soon enough, these young DJs became national superstars… until the British government decided it was time to sink these pirates once and for all. This story comes from the History This Week podcast.

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)

On January 10, 1991, the U.S. Army Intelligence School Devens (USAISD) introduced the Basic Morse Mission Trainer to the 98H Morse intercept operator and 98D emitter identifier/locator advanced individual training courses. This system revolutionized the training of Morse code copying skills for both students and instructors, reducing course attrition, and turning out better trained operators faster. Continue reading

Absolute Radio to switch off all AM transmitters across the UK (Radio Today)

Bauer is removing Absolute Radio from Medium wave this month as it turns off all AM frequencies for the station across the country.

Absolute Radio launched exclusively on AM (as Virgin Radio) 30 years ago in 1993 using predominantly 1215 kHz along with fill-in relays on 1197, 1233, 1242 and 1260. Some of these have been turned off in recent years in places such as Devon, Merseyside and Tayside.

Whilst this is a historic milestone for the radio industry, it shouldn’t affect many listeners as just two percent of all radio listening currently takes place on AM.

Absolute Radio also lost its FM frequency in London in 2021 in favour of the ever-expanding Greatest Hits Radio network.

The move makes Absolute Radio a digital-only service, broadcasting nationally on DAB and online. [Continue reading…]

Coffee and Radio – with Carlos Latuff (Radio Heritage)

[…]Carlos Henrique Latuff de Sousa or simply “Carlos Latuff”, for friends, (born in Rio de Janeiro, November 30, 1968) is a famous Brazilian cartoonist and political activist. Latuff began his career as an illustrator in 1989 at a small advertising agency in downtown Rio de Janeiro. He became a cartoonist after publishing his first cartoon in a newsletter of the Stevadores Union in 1990, and continues to work for the trade union press to this day.

With the advent of the Internet, Latuff began his artistic activism, producing copyleft designs for the Zapatista movement. After a trip to the occupied territories of the West Bank in 1999, he became a sympathizer of the Palestinian cause in the context of the Israeli-Palestinian conflict and devoted much of his work to it. He became an anti-Zionist during this trip and today helps spread anti-Zionist ideals.

His page of Instagram (https://www.instagram.com/carloslatuff/) currently has more than 50 thousand followers, where of course you can see his work as a cartoonist and also shows his passion for radio. [Continue reading…]

X-CLASS SOLAR FLARE (Speaceweather.com)

A large and potentially dangerous sunspot is turning toward Earth. This morning (Jan. 6th at 0057 UT) it unleashed an X-class solar flare and caused a shortwave radio blackout over the South Pacific Ocean. Given the size and apparent complexity of the active region, there’s a good chance the explosions will continue in the days ahead. Full story @ Spaceweather.com ( https://spaceweather.com)

Looking to Ditch Twitter? Morse Code Is Back (Smithsonian Magazine)

For almost 20 years, Steve Galchutt, a retired graphic designer, has trekked up Colorado mountains accompanied by his pack of goats to contact strangers around the world using a language that is almost two centuries old, and that many people have given up for dead. On his climbs, Galchutt and his herd have scared away a bear grazing on raspberries, escaped from fast-moving forest fires, camped in subfreezing temperatures and teetered across a rickety cable bridge over a swift-moving river where one of his goats, Peanut, fell into the drink and then swam ashore and shook himself dry like a dog. “I know it sounds crazy, risking my life and my goats’ lives, but it gets in your blood,” he tells me by phone from his home in the town of Monument, Colorado. Sending Morse code from a mountaintop—altitude offers ham radios greater range—“is like being a clandestine spy and having your own secret language.”

Worldwide, Galchutt is one of fewer than three million amateur radio operators, called “hams,” who have government-issued licenses allowing them to transmit radio signals on specifically allocated frequencies. While most hams have moved on to more advanced communications modes, like digital messages, a hard-core group is sticking with Morse code, a telecommunications language that dates back to the early 1800s—and that offers a distinct pleasure and even relief to modern devotees.

Strangely enough, while the number of ham operators is declining globally, it’s growing in the United States, as is Morse code, by all accounts. ARRL (formerly the American Radio Relay League), based in Newington, Connecticut, the largest membership association of amateur radio enthusiasts in the world, reports that a recent worldwide ham radio contest—wherein hams garner points based on how many conversations they complete over the airwaves within a tight time frame—showed Morse code participants up 10 percent in 2021 over the year before.

This jump is remarkable, given that in the early 1990s, the Federal Communications Commission, which licenses all U.S. hams, dropped its requirement that beginner operators be proficient in Morse code; it’s also no longer regularly employed by military and maritime users, who had relied on Morse code as their main communications method since the very beginning of radio. Equipment sellers have noticed this trend, too. “The majority of our sales are [equipment for] Morse code,” says Scott Robbins, owner of ham radio equipment maker Vibroplex, founded in 1905, which touts itself as the oldest continuously operating business in amateur radio. “In 2021, we had the best year we’ve ever had … and I can’t see how the interest in Morse code tails off.”

Practitioners say they’re attracted by the simplicity of Morse code—it’s just dots and dashes, and it recalls a low-tech era when conversations moved more slowly. For hams like Thomas Witherspoon of North Carolina, using Morse code transmissions—sometimes abbreviated as CW, for “continuous wave”—offers a rare opportunity to accomplish tasks without high-tech help, like learning a foreign language instead of using a smartphone translator. “A lot of people now look only to tools. They want to purchase their way out of a situation.”

Morse code, on the other hand, requires you to use “the filter between your ears,” Witherspoon says. “I think a lot of people these days value that.” Indeed, some hams say that sending and receiving Morse code builds up neural connections that may not have existed before, much in the way that math or music exercises do. A 2017 study led by researchers from Ruhr University in Bochum, Germany, and from University Medical Center Utrecht in the Netherlands supports the notion that studying Morse code and languages alike boosts neuroplasticity in similar ways.

Supermarket delivery driver saves 90-year-old after ‘SOS’ Morse code signal on car horn (ITV)

A 90-year-old widower was saved by an supermarket delivery driver when he broke his hip – and used his car horn as Morse code.

Retired panel beater Keith Turner was left injured when he slipped on his driveway before he dragged himself to his car.

The quick-thinking pensioner then used the horn to sound out the SOS message in Morse code in a cry for help.

And it was heard by delivery driver Sam Speechley, 45, as she pulled up in her van in the Garden City village in Flintshire, North Wales.

Keith was taken to hospital where he spent three weeks with a broken hip before he was finally allowed home. [Click here to read at ITV…]

Vatican Radio hosts ‘G9’ of short wave media as ‘missionaries of peace’ (Vatican Radio)

Gathered at the historic headquarters of Vatican Radio in the Vatican Gardens, representatives of the nine primary western radio broadcasters meet with Monsignor Lucio Ruiz opening the meeting by recalling the importance of short wave in sending messages of hope and mercy all over the world.

By Michele Raviart

The “G9” group of the primary western radio broadcasters met at the Vatican on Tuesday focusing on a number of issues.

These included the use of short-wave radio in order to render the jamming of international broadcasters less effective through common efforts to coordinate how broadcast frequencies are used and technical cooperation between members.

This marked a key item on the agenda of the meeting which brought together the representatives, including Vatican Radio, in the historic building of the Pope’s radio, located in the Vatican Gardens, a place that housed the first radio station built by Guglielmo Marconi.

Andy hears Morse Code in B52s concert

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

Thomas,

I was just listening  to an old B52’s music gig on YouTube when it got
to 51:57 mins in.

You can clearly hear NAWS DE CFH and some other stuff.

How did that get there–?

73 de Andy

Thanks for sharing, Andy!

Ah yes, Planet Claire! I actually heard the eB52s play this one live at a concert in the early 90s.

The “CHF” that you hear is the callsign of the Canadian Forces Station Mill Cove. This is a partial recording of a CHF broadcast listing frequencies for RTTY transmissions. The B52s have been known to incorporate radio feedback and snippets in their work. You can hear CW more clearly in this video:

In fact, when I saw the B52s live, Fred Schneider used a walkie talkie Morse Code button (the type that you could find on kids’ walkie talkies) for audio feedback in at least Planet Claire and Rock Lobster

I bet there are some other B52s fans out there who will have even more insight! Thanks again, Andy!

Interview about Brooklyn pirate radio (Irish Pirate Radio Audio Archive)

Although Irish pirate radio is our main interest, today we explore the lively pirate scene in the Brooklyn area of New York City. The Brooklyn Pirate Radio Sound Map is a fascinating project established by radio producer and audio archivist David Goren and provides interactive maps and historical and contemporary recordings of the many unlicensed stations in Brooklyn.

This is a longer version of an interview by John Walsh with David Goren first featured in Wireless, a series about radio, audio and media on Flirt FM in Galway. It covers the history of pirate radio in Brooklyn and New York generally, attempts to crack down on the unlicensed stations, the role of low-powered FM, the background to the Brooklyn Pirate Radio Sound Map itself and plans for the future. Many thanks to David for taking the time to explain this fantastic project for us. [Read the full article and listen to the interview on the Irish Pirate Radio Audio Archive…]

The Evolution of the Emergency Radio (Radio World)

From AM-only portables to multi-function machines

With the advent of the 9V battery-powered transistor radio in the 1950s, the “Emergency Radio” was born.

Unlike vacuum tube receivers with heavy batteries or unpowered crystal radios, these handheld AM portables were small and simple enough to keep in a drawer. They could then be retrieved whenever man-made or natural disasters knocked out the power, providing listeners with lifeline connections to news, weather and relief information. Continue reading
