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design requirement, certain carmakers may need to scrap advanced safety features, with engineers having to prioritize outdated technology over current or future safety innovations,” they wrote.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:

Biggest change for CBs in four decades as FM mode gets approved by FCC (CCJ Digital)
The biggest change for CB radios in the U.S. since the late 1970s is coming and it looks to be a good thing for improved voice quality and cutting through frustrating background noise common at the peak of day.
The Federal Communications Commission (FCC) recently approved FM to join alongside AM and single-sideband (SSB) modes on CBs. It’s a big change to old technology that offers some clear advantages.
On the plus side, FM will provide users with improved audio quality and greater ability to circumvent background signal noise typical on CB’s long-standing AM side. The Department of Electrical Engineering and Computer Sciences at U.C. Berkeley reports that FM will provide an “improved signal to noise ratio (about 25dB) with regards to man-made interference” over AM. That kind of reduction in background noise could prove popular with truckers who remain among the top users of CBs in the U.S.
Live video of startup, tuning, and transmitting from Alexanderson Alternator SAQ
Hats off to the crew at the UNESCO World Heritage Grimeton Radio Station!
Today is Sunday July 4, 2021. Besides being Independence Day here in the States, it’s also Alexanderson Day in Sweden!
This morning, I discovered a video on the Grimeton Station YouTube channel: a recording of their live stream live stream starting around 08:30 UTC today.
In the video, you can watch the crew of the Grimeton station startup, tune, and transmit on their 1924 Alexanderson Alternator with the callsign SAQ. Their message is sent in CW on 17.2 kHz. The video is absolutely fascinating and I highly recommend watching it. The startup and tuning procedure are simply amazing. I can only imagine the dedication and resources it takes to keep this marvel of 1920s engineering fully functional today:

Happy July 4th, everyone!

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…
