Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: 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 L, Pete Eaton, David Iurescia, and Troy Riedel for the following tips:

Podcast #294 – Reading the PIRATE Act / FCC & the Supremes Pt. 2

The PIRATE Act was signed into law more than a year ago, but the rules governing increased fines for unlicensed broadcasting are about to go into effect on April 26. The Act is intended to give the FCC additional tools for tamping down pirate radio activity in hot beds like Boston and Brooklyn, NY, but there are reasons to be skeptical.

Brooklyn-based writer, post-production mixer and field recordist David Goren joins to help us tease out the real-world implications. Goren is also the creator of the Brooklyn Pirate Radio Sound Map and has been monitoring and recording unlicensed radio activity in the borough for decades.

Also joining the show is Dr. Christopher Terry from the University of Minnesota. A professor of media law, he helps illuminate some of the legal and bureaucratic elements that complicate the Commission’s efforts. He also catches us up on the latest development in the battle over media ownership rules, with the Supreme Court issuing a narrow unanimous ruling in favor of the FCC’s most recent changes, but not quite addressing the decades-long gridlock in that policy area.

WSPR May Hold The Key To MH370 Final Position (Hackaday)

The disappearance of Malaysia Airlines flight MH370 after an unexplained course change sent it flying south over the Indian Ocean in March 2014 still holds the mystery of the wreck’s final location. There have been a variety of efforts to narrow down a possible search area over the years, and now we have news of a further angle from an unexpected source. It’s possible that the aircraft’s path could show up in radio scatter detectable as anomalously long-distance contacts using the amateur radio WSPR protocol.

WSPR is a low-power amateur radio mode designed to probe and record the radio propagation capabilities of the atmosphere. Transmit beacons and receiving stations run continuously, and all contacts however fleeting are recorded to an online database. This can be mined by researchers with an interest in the atmosphere, but in this case it might also provide clues to the missing airliner’s flightpath. By searching for anomalously long-distance WSPR contacts whose path crosses the expected position of MH370 it’s possible to spot moments when the aircraft formed a reflector for the radio waves.[…]

Bob Fass, Pioneer of Underground Radio, Dies at 87 (NY Times)

His provocative “Radio Unnameable,” long a staple of the New York station WBAI, offered a home on the FM dial to everyone from Abbie Hoffman to Tiny Tim.

Bob Fass, who for more than 50 years hosted an anarchic and influential radio show on New York’s countercultural FM station WBAI that mixed political conversation, avant-garde music, serendipitous encounters and outright agitation, died on Saturday in Monroe, N.C., where he lived in recent years. He was 87.

His wife, Lynnie Tofte, said he had been hospitalized with Covid 19 earlier in the month, but he died of congestive heart failure.

Vatican Radio celebrates 30th International Marconi Day

The Dicastery for Communication marks the 30th International Marconi Day with a celebration at Vatican Radio’s historic broadcast station outside Rome.

International Marconi Day is held every year on the Saturday closest to the birthday of the inventor of the radio, Guglielmo Marconi, on 25 April 1874.

This year’s commemoration fell a day earlier, and saw dozens of radio stations exchange messages, including Vatican Radio, which Marconi himself helped found in 1931.

The 30th iteration of Marconi Day was celebrated at Vatican Radio’s broadcast center at Santa Maria di Galeria, outside Rome.

Day for those who love radio

According to Dr. Paolo Ruffini, the Prefect of the Dicastery for Communication, it was “a day spent in a family spirit” for those who love the Radio and the man who invented it.

He noted that the broadcast station forms both the center and periphery of Vatican Radio, since it is the place where radio waves are emitted which carry the Gospel and the words of the Popes throughout the world.

Marconi’s favorite Radio

The 30th Marconi Day falls within the 90th anniversary year of the founding of Vatican Radio.

The great Italian inventor’s daughter, Princess Elettra Marconi, who was present for the celebration, recalled that the station was her father’s favorite, though he had founded several others.[…]

SpaceX Encrypts Falcon 9 Telemetry After Amateur Radio Operators Download Data (Extreme Tech)

SpaceX doesn’t operate like a traditional aerospace company. For one, the CEO is usually hamming it up on Twitter during launches and providing details that would usually go in a press release. SpaceX also live streams almost all of its launches, even the prototypes that have an unfortunate tendency to blow up lately. It wasn’t even encrypting the Falcon 9 telemetry feed… until now. Unfortunately, some digging by amateur radio tinkerers seems to have convinced SpaceX to step up its security.

It all started a few weeks ago when several Redditors managed to lock onto the 2232.5 MHz telemetry downlink from a Falcon 9 upper stage. Right away, they were able to pull out a few interesting plaintext snippets from the unencrypted feed. With a little more work, the radio enthusiasts were able to capture some amazing images from the spacecraft’s cameras.

After that discovery was public, other SpaceX fans tried to grab some data from the Starship during its prototype tests. However, SpaceX had chosen to encrypt that data. Even with the right wireless equipment, the decoded signal was just noise. Now, it appears the same thing is happening with the Falcon 9. When attempting to pull data from the most recent Falcon 9 launch, the original signal snoopers discovered it had also been encrypted. A series of tweets from SpaceX engineers suggest the decoding of the telemetry signal was the reason for the change.[…]

Postcard from Titanic’s radio operator is being sold at auction (Stars And Stripes)

BOSTON — A postcard written by the Titanic’s senior radio operator just weeks before the ocean liner sank in the North Atlantic in 1912 has been put up for auction.

The card, with a glossy image of the ill-fated ship on the front, was written by Jack Phillips to his sister, Elsie Phillips, in March 1912 while awaiting the ship’s first sea trials, according to RR Auction in Boston.

“Very busy working late. Hope to leave on Monday & arrive Soton Wednesday afternoon. Hope you quite OK. Heard from Ethel yesterday,” he wrote. It’s signed “Love Jack.”

It is postmarked Belfast, where the Titanic was built, and has a canceled halfpenny stamp.

“Soton” is a contraction of Southampton, the English port city from where the Titanic departed on its maiden voyage. It sank in the early morning hours of April 15.

Phillips, who turned 25 on board, stayed at his post after the Titanic struck an iceberg to send calls for assistance to other ships in the area until water was lapping around his feet, according to RR Auction.

He made it off the ship after being told by the captain that he had done his duty, according to his biography in the British National Archives, but died of exposure in the frigid North Atlantic, according to RR Auction.

The postcard is being sold by the estate of Vera and John Gillespie, longtime members of the Massachusetts-based Titanic Historical Society, said Bobby Livingston, executive vice president at RR Auction.[…]

Radio Survivor Podcast #292: The History of Sound Art (Radio Survivor)

What is sound art? And what do we know about its origin story? We explore this question and more with our guest this week, artist and educator Judy Dunaway. An adjunct professor in the History of Art Department at Massachusetts College of Art and Design, Dunaway’s recent article, “The Forgotten 1979 MoMA Sound Art Exhibition,” is a fascinating look at the history of sound art and highlights important contributions by female artists. In our wide-ranging discussion, we also hear about Dunaway’s own artistic practice, from her work with latex balloons to transmission art to a “phone improv” show over BlogTalkRadio a decade ago.

Overcoming the Limitations of Time (From the January/February 1940 WNYC Masterwork Bulletin)

A MATTER OF RECORD: Mighty useful gadgets are WNYC’s four new recording machines. They were used in a variety of interesting ways during the past year, so we decided that the how and the why of recording would be an appropriate subject for this, the third of our Behind the Microphone series dealing with the technical side of things at the Municipal Station.

One of the most valuable uses of the recording units is that they have partially enabled us to overcome the limitations of time — have made it possible to make available to our listeners important evening programs which we could not broadcast directly because of our fluctuating time allotment.

For instance, we could not pick up the ASCAP Music Festival Concerts from Carnegie Hall last Fall because WNYC was not on the air after 8:30 P. M.[1] What to do? The recorders to the rescue! The concerts were “broadcast” over our regular Carnegie Hall lines to the Municipal Building where they were transcribed on our two standard studio-type recording machines. Each transcription[2] was put on the air on the afternoon following the original perfor

Similarly, our two mobile recording units made possible an afternoon broadcast of the official opening of La Guardia Field which took place at midnight. Recording equipment is also used frequently to transcribe major programs “off the air” so that they may reach a larger audience through rebroadcast. There was the time, for example, when the Mayor’s office was the scene of a final report on the new Police and Fireman’s pension plan. Official reports on the balloting were recorded and rebroadcast at a time when the majority of the policemen and firemen affected could listen in.

We used to think recording an easy job: Just put the recording needle on the disk, turn a few buttons, and let ‘er go. After watching one of our expert recording engineers at work, we realized that it’s a delicate task, requiring special training and long practice.

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Eric McFadden, Mike Terry, for the following tips:

A “Perfect Coronal Mass Ejection” Could Be a Nightmare (ARRL News)

A new study in the research journal Space Weather considers what might happen if a worst-case coronal mass ejection (CME) hit Earth — a “perfect solar storm,” if you will.

In 2014, Bruce Tsurutani of Jet Propulsion Laboratory (JPL) and Gurbax Lakhina of the Indian Institute of Geomagnetism introduced the “perfect CME.” It could create a magnetic storm with intensity up to the saturation limit, a value greater than the Carrington Event of 1859, the researchers said. Many other spaceweather effects would not be limited by saturation effects, however. The interplanetary shock would arrive at Earth within about 12 hours, the shock impingement onto the magnetosphere would create a sudden impulse of around 234 nanoteslas (nT), and the magnetic pulse duration in the magnetosphere would be about 22 seconds. Orbiting satellites would be exposed to “extreme levels of flare and interplanetary CME (ICME) shock-accelerated particle radiation,” they said. The event would follow an initial CME that would “clear the path in front of it, allowing the storm cloud to hit Earth with maximum force.”

The Solar and Heliospheric Observatory (SOHO) has observed CMEs leaving the sun at speeds of up to 3,000 kilometers per second, and many instances of one CME clearing the way for another have been recorded.

The CME’s 12-hour travel time would allow little margin for preparation. The CME would hit Earth’s magnetosphere at 45 times the local speed of sound, and the resulting geomagnetic storm could be as much as twice as strong as the Carrington Event. Power grids, GPS, and other services could experience significant outages.

More recent research led by physicist Dan Welling of the University of Texas at Arlington took a fresh look at Tsurutani and Lakhina’s “perfect CME,” and given improvements in spaceweather modeling, he was able to reach new conclusions.

Welling’s team found that geomagnetic disturbances in response to a perfect CME could be 10 times stronger than Tsurutani and Lakhina had calculated, especially at latitudes above 45 to 50 °. “[Our results] exceed values observed during many past extreme events, including the March 1989 storm that brought down the Hydro-Québec power grid in eastern Canada, the May 1921 railroad storm, and the Carrington Event itself,” Welling summarized.

A key result of the new study is how the CME would distort and compress Earth’s magnetosphere. The strike would push the magnetopause down until it’s only 2 Earth-radii above Earth’s surface. Satellites in Earth orbit would suddenly find themselves exposed to a hail of energetic, and potentially damaging, charged particles.

Other research has indicated that phenomena such as the Carrington Event may not be as rare as once thought. A much weaker magnetic storm brought down the Canadian Hydro?Québec system in 1989.

Scientists believe a perfect CME will happen someday. As Welling et al conclude, “Further exploring and preparing for such extreme activity is important to mitigate spaceweather-related catastrophes.”

In July 2012, NASA and European spacecraft watched an extreme solar storm erupt from the sun and narrowly miss Earth. “If it had hit, we would still be picking up the pieces,” said Daniel Baker of the University of Colorado at a NOAA Space Weather Workshop 2 years later. “It might have been stronger than the Carrington Event itself.”

FCC To Auction Off 140 Radio Stations (Radio Ink)

The FCC has announced that on July 27th an auction will be held for 136 FM construction permits and 4 AM’s. In this auction, the 130 FM permits that were previously included in the March 2020 auction, that had to be canceled due to COVID, will be included plus an additional 6 permits. Anyone who applied for stations in the planned 2020 auction must reapply. All applications for the previous auction have been dismissed.

[…]You can see the FM stations to be auctioned off HERE.

The Commission is proposing a simultaneous multiple-round auction format. This type of auction offers every construction permit for bid at the same time and consists of successive bidding rounds in which qualified bidders may place bids on individual construction permits. Typically, bidding remains open on all construction permits until bidding stops on every construction permit.

Why There’s More Music on AM Now (Radio Survivor)

by Paul Riismandel

A number of months ago I was scanning around the AM dial late in the evening from my Portland, Oregon abode. I stumbled upon a station playing hard rock, which I thought to be an unusual find. As the AM dial has become mostly the domain of conservative and sports talk, I rarely encounter music that isn’t a bumper or part of some leased-time foreign-language programming.

In fact, at first I thought perhaps the music was a lead-in to just another talk show, but eventually I heard a full set of three songs. The station identified itself as “The Bear,” but curiously gave an FM frequency, not one on the AM dial.

An internet search the next day confirmed that “the Bear” is indeed an active rock formatted station located in Merced, California. Its logo features 105.7 FM prominently, with the 1660 AM frequency tucked in the corner. Yet, the AM signal is actually the primary one – the FM is a 250 watt repeater (translator) station.

Here’s a quick aircheck of the Bear’s station ID, during a break in the syndicated hard rock “Loudwire” program.

Now, AM stations have been permitted to get FM translators for a few years now as part of the FCC’s so-called “AM revitalization” initiative. But mostly I’ve heard sports and news/talk stations get repeated on FM.

I filed away this experience in memory, but kind of considered it a one-off. That was until my recent vacation in the Wallowa Mountains of Northeastern Oregon. Stowed away and social distancing in a mountainside cabin with limited internet and no cable, I spent quite a bit of time scanning the AM and shortwave bands in search of interesting sounds.

(Source: Radio Survivor)

Over the past few months, there’s been a flurry of media attention focused on the United States Agency for Global Media (USAGM). Some reports describe it as a “little-known” agency and, in fact, it may seem mysterious to many in the United States, since it oversees international broadcasting programs all over the world, including Voice of America and Radio Free Europe/Radio Liberty.

USAGM has been in the news following the appointment of new CEO Michael Pack, subsequent personnel changes, and even a congressional hearing on September 24. This week we explore the history of USAGM and talk about some of the recent changes at the organization. We are joined on the show by Jane Curry (Professor of Political Science at Santa Clara University), Mark Pomar (National Security Fellow at Clements Center for National Security at University of Texas, Austin) and Brandon Burke (Associate Archivist at the Hoover Institution Archives). Jennifer Waits and Eric Klein host this week’s episode.

Talking shortwave and spectrum on the Radio Survivor podcast

5 Replies

Last week, I had the honor of speaking with Eric Klein and Jennifer Waits on the excellent Radio Survivor podcast. It’s rare that in one show I get to spread so much shortwave radio love–thanks for making that happen Radio Survivor:

Perhaps you are like me and you have wished that you could go back in time and spin a radio dial and just listen to and browse the full radio spectrum from another time and place. Our guest on the show, Radio Anthropologist Thomas Witherspoon, is building a website for just such a thing. It’s called the Radio Spectrum Archive and it is not magic, it uses a piece of technology called a software defined radio that makes recording a full spectrum of Shortwave, AM and even FM radio (if you have the computing power to handle the load) a very real possibility. Thomas Witherspoon is also the primary contributor to The Shortwave Listening Post (www.swling.com) so we are going to learn a few things about the wonder that is shortwave radio on planet earth.

Radio Survivor podcast highlights “The FCC’s Effort To Decimate Community Media”

2 Replies

Many thanks to SWLing Post contributor, William Lee, who shares the Radio Survivor’s Podcast #166: The FCC’s Effort To Decimate Community Media:

The FCC has proposed to de-fund community media through an arcane rule that determines how contributions from cable companies to public-access, educational and government (PEG) stations are counted. Because it’s arcane, the effort is flying under the radar. But we have two community media advocates to help explain what’s at stake.

Martin Jones is the CEO of MetroEast Community Media in Gresham, Oregon, just one of hundreds of PEG stations that would be affected. Sabrina Roach serves on the board for the Alliance for Community Media Foundation, the charitable arm of the group that represents and organizes PEG stations across the U.S. They tell us how proposed changes to the “franchise fee” structure would deprive PEG stations, as well as internet access at libraries and schools, from direct funding. If passed, this would decimate both community media and digital equity in most communities that have it. They also explain what steps we can take to oppose this change.
