DLARC: The Radio Geek’s Doomscrolling Antidote (Radio World)

The internet has aged to the point where it is easy to fall into a rabbit hole, reminiscing about websites from decades past.

The site that fuels those scrolling endeavors is the Internet Archive — a nonprofit that hosts a digital library of internet sites and other artifacts in digital form. The project began in 1996 to archive the web.

Today, it contains one trillion web pages through its “Wayback Machine,” as well as 56 million books and texts. It also works with approximately 1,400 libraries through its Archive-It program to identify and preserve important digital history.

Kay Savetz (K6KJN) freely admits to having been an Internet Archive power user. Savetz used not just the archive.org website, but also its command line interface to upload many documents. [Continue reading…][Continue reading…]

Solar Cycle 25 Gives Amateurs and Shortwave a Boost (Radio World)

Beyond their love of radio, amateur radio operators and shortwave radio broadcasters have one thing in common: They rely on the ionosphere to refract or bend their signals back to Earth, so that they can travel beyond line-of-sight distances.

In turn, the ionosphere’s ability to refract radio signals depends on its level of ionization or charge. The more ionized the ionosphere is, the more likely it is to bend signals back to the ground rather than let them pass through.

Here’s where the sun comes in. The number of sunspots on the solar surface rises and falls over an 11-year period, during what is known as a solar cycle. The more sunspots, the more solar radiation comes to Earth. [Continue reading…]

City of Delano plans to sell Voice of America property, keep portion for ‘future park purposes’ (KGET)

BAKERSFIELD, Calif. (KGET) — The city of Delano is looking to keep a portion of the former Voice of America property for “future park purposes” and sell the rest, according to the Delano City Council agenda for Monday.

The property is on about 800 acres bordered by West Garces Highway, Woollomes Avenue, Melcher Road and Casey Avenue.

It was home to the Delano Transmitting Station, built in 1944 to broadcast Voice of America programming worldwide. It stopped operating in 2007 and was demolished shortly after.

The City Council is set to consider whether it should retain about 20 acres of that property for park-related reasons and designate the remainder as “surplus land” and approve selling it. [Continue reading…]

Remembering CBS Radio’s Beginnings (Radio World)

The recent news that CBS is shuttering its radio network caused us to reflect on the glorious 99-year history of the company’s radio business, and gaze backward from this stretch of the road toward the media organization’s beginnings.

In the 1920s, Arthur L. Judson was a well-known manager of musical artists. After a meeting with RCA chief David Sarnoff, he thought he had a verbal agreement to provide musical talent for the new National Broadcasting Company, but he soon discovered that Sarnoff had instead set up his own NBC artist’s bureau. Furious over the humiliation of being outmaneuvered, Judson resolved to start his own radio network, to be called the United Independent Broadcasters.

He lined up a few investors, rented studio space at WOR in New York and signed up 16 stations. The network would pay the stations for carrying its programs, plus the talent costs and the hefty AT&T network line charges. All expenses would be paid for by advertising. The Columbia Phonograph Company agreed to provide an infusion of cash, and it became the Columbia Phonograph Broadcasting System. [Continue reading….]

After CBS: Let’s Take Back the Airwaves (Radio World)

It’s a wakeup call. Our future should belong to Main Street not Wall Street

The announcement of the pending shutdown of CBS News Radio isn’t just another media headline — it’s a wake-up call.

A clear example of what happens when decisions about our information, our communities and our voices are made in corporate boardrooms disconnected from real life.

This wasn’t a programming failure. It wasn’t a lack of audience. It was an accounting decision — made by people who don’t live in the communities radio serves, don’t rely on it and don’t understand its true value.

And that’s exactly why they got it wrong.

Radio has never been more important. In an era flooded with misinformation, algorithm-driven content and faceless digital noise, radio remains immediate, local and — most importantly — trusted. It’s the one medium that still shows up live, every day, in real time, for real people. [Continue reading…]

Empowering Airwaves: Women-Led Radio Stations Amplify Unheard Voices (Nieman Reports)

On March 8, 2021, a new radio station launched in Kabul: Radio Begum, run by women, for women. The timing was deliberate — the station opened on International Women’s Day, and just as the United States military was withdrawing from Afghanistan.

“I decided to launch this radio station in order to be ready for the day the Taliban takes power,” said Hamida Aman, the station’s founder. “We knew that as soon as they take power, it will be segregation, and again, it will be against women.”

Five months later, the Taliban retook Kabul and imposed new laws restricting women’s access to schools and their movements in public. Five years later, Radio Begum is still on the air. The station follows the letter of the law, even as restrictions tighten. It doesn’t cover politics or any subjects that are off-limits to public discussion among women under Taliban edicts. Instead, it focuses on health, religion, and providing educational programs to replace the schooling women are now prohibited from receiving.

“They banned schools, but not education,” Aman said. [Continue reading…]

Does a ‘Great Firewall’ loom? Why Russians are buying up walkie-talkies and road maps (SBS News)

Pagers, walkie-talkies and portable radios have reportedly been flying off the shelves of Moscow after the city’s roughly 13 million residents were hit with week-long internet disruptions, which some believe could be part of the Kremlin’s trial of a nationwide internet censorship system.

The blackout, which was first reported on 5 March, occurred initially in some of out suburbs in the capital, Moscow, before later spreading through the city’s downtown areas.

During the disruption, many foreign websites were blocked on mobile phones, while online government services, top banks and taxi apps also stopped working.

Russian media outlet Kommersant estimated that a five-day shutdown cost the city’s businesses between $54 million and $89 million. [Continue reading…]

An Audience Crisis at WLRH (Michael Krall – Blog)

The latest audience numbers from WLRH reflect a new reality — the audience that once listened for NPR programming is gone.

The station posted a 1.3 share for January 2026 (Nov-Dec-Jan).

This is a real loss caused directly by the format change.

Because WLRH dropped all NPR programming on October 1, 2025, this book represents the first full three months of the new format. (See my previous post for a more detailed explanation on how the Huntsville radio market is measured.) [Continue reading…]

Many thanks to SWLing Post contributor Dennis Dura, who shares this Radio World report on a proposed U.S. congressional spending bill that would include continued funding for the Voice of America and its parent agency, the U.S. Agency for Global Media. The bipartisan proposal would allocate roughly $653 million to support VOA’s international broadcasting mission and related services, signaling congressional backing for global news and information distribution even as the bill still must clear final approval: https://www.radioworld.com/news-and-business/business-and-law/proposed-congress-spending-bill-includes-voa-funding

Hackaday: The Cold War-Era Survivable Low-Frequency Communication System (SLFCS)

Many thanks to SWLing Post contributor Dennis Dura, who shares the following article about Cold War–era low-frequency communications, from Hackaday:

During the Cold War, the U.S. developed the Survivable Low-Frequency Communication System (SLFCS) — a radio network designed to function even after a nuclear attack. Using long-wavelength LF and VLF signals that can travel vast distances through ground and ionospheric waveguides, SLFCS provided a way to deliver emergency launch orders when all else failed. The system’s immense towers and buried loop antennas reflect an era when reliability was paramount — even under atomic conditions.
