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!

The DJ Who Broadcast to One Listener for 40 Years (Narratively)

The Deke Duncan show on Radio 77 had it all — the latest hits, bouncy jingles, and a DJ who was born to be on the airwaves. In the 1970s it ran around the clock, several days a week, playing to the smallest audience in the world: Deke’s only listener was his wife. Radio 77 was based in a shed in Duncan’s backyard in a small English town, and everything on the show was a figment of his imagination. “My ultimate ambition would be to broadcast my radio station to the rest of Stevenage,” he told the BBC’s Nationwide TV show, when they visited his shed in 1974.

In a new podcast episode from Snap Judgement and Narratively, Duncan, now 75, reveals how he made up the news, the weather, and even the commercials — and kept Radio 77 alive for over forty years. It was Britain’s ‘pirate’ radio stations that inspired him, he said, recalling the rock’n’roll ships that broadcast illegally from international waters in the 1960s. But the young DJ’s dreams had been dashed when the BBC turned down his job application.

“They said, ‘I suggest you go away and get yourself a real job,’” Duncan recalled. (Check out an original Radio 77 show, recorded in 1974.) [Continue reading…]

Why UNESCO Believes in Radio (Red Tech)

Chief, Media Development and Media and Information Literacy at UNESCO Mirta Lourenço shares insight on radio’s evolution and challenges. She explains how the international organization is working to support radio stations around the world to ensure they’re able to accomplish their crucial mission.

RedTech: How do you view the role of radio in our society?

Mirta Lourenço: Thanks to radio, we benefit from many essential public services that we seldom reflect on. These include global positioning systems, satellite navigation, environmental monitoring, intelligent transport systems, space research, etc. Radio broadcasts offer information and the possibility for people to participate, regardless of their literacy levels and socio-economic situation.

The medium is also especially suited for multilingualism. Audiences may need to hear programs in their primary language, particularly if said language is local and endangered, or in the case of refugee radio or isolated communities. Also, when literacy levels are low, local languages are crucial to the populations’ access to information, as radio constitutes the main source for reliable journalism. History has shown us that radio is the most effective emergency communication system and in organizing disaster response.

All this does not mean that radio broadcasting is free from challenges. Continue reading →

Radio Waves: Stories Making Waves in the World of Radio

Can Radio Really Educate? (JSTOR Daily)

In the 1920s, radio was an exciting new mass medium. It was known for providing entertainment, but educators wondered if it could also be used for education.

It was mid-1922 and America was in the midst of the radio craze. Commercial broadcasting had emerged in a handful of cities in 1920, but at that time, few people had a receiving set—except for amateur radio operators, who knew how to build one. It wasn’t even called “radio” back then—newspapers referred to it as “radiophone” or “wireless telephone.” But only two years later, there were several hundred radio stations on the air, and you could purchase a radio in a store—although hobbyists still had fun trying to build their own, with varying degrees of success. Meanwhile, the word “radio” had become the common term for that wonderful new invention that everyone wanted in their home.

Today, we tend to take radio for granted; it is one of many ways to hear music or news or sports. But in 1922, radio was unique: it was the first mass medium to take people to an event in real time, and listeners were amazed by it. Suddenly, they could hear a popular orchestra coming through the radio set. Without leaving their home, they could listen to a baseball game, or an inspirational talk from a preacher; some stations even had the latest news headlines. In an era when traveling from one city to another could take hours (the popular Model T Ford had a top speed of 40-45 mph, and superhighways had not yet come along), listeners could travel by radio, hearing stations from distant cities. Before radio, only the wealthy could attend a concert featuring a famous vocalist, but now, anyone who had a receiving set could hear that singer’s music. And in an America that was still racially segregated, radio gave some musicians of color the opportunity to be heard by thousands of listeners. In magazines and newspapers, radio inspired “utopian hopes and bold predictions.” Writers referred to it as a cure for loneliness—especially for people living in rural areas or on the farm. It was also praised for helping the blind gain greater access to the world around them. More than one writer claimed radio would bring world peace, since everyone would unite around their favorite programs. And of course, as a sign of American progress, it was something no home should be without, not even the White House: President Harding was an enthusiastic radio fan, and had a set installed near his desk, so he could listen whenever he wanted to.

Psychics once ruled the airwaves thanks to the Texas-Mexico border and the magic of radio (KUT)

A new book includes details of how powerful radio stations along the border helped former vaudeville actors reach larger audiences.

In the 1920s and ’30s, some of the most popular radio programs in the United States featured radio psychics. The most successful among them made hundreds of thousands of dollars reading the minds and predicting the futures of eager listeners. To do it, they took advantage of a new and mysterious medium: radio. Continue reading →

Significant X-class solar flare (Southgate ARC)

There was a global eruption on the sun today. It started with a powerful X1-class solar flare from sunspot AR2887.

The blast created a massive tsunami of plasma in the sun’s atmosphere, which rippled across the entire solar disk. A CME is probably heading for Earth, raising the possibility of a geomagnetic storm on Halloween. More information and updates @ Spaceweather.com.

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.

CBQM

This feature-length documentary pays tribute to CBQM, the radio station that operates out of Fort McPherson, a small town about 150 km north of the Arctic Circle in the Canadian Northwest Territories. Through storytelling and old-time country music, filmmaker and long-time listener Dennis Allen crafts a nuanced portrait of the “Moccasin Telegraph,” the radio station that is a pillar of local identity and pride in this lively northern Teetl’it Gwich’in community of 800 souls.

CBQM, Dennis Allen, provided by the National Film Board of Canada

This is wonderful, Ted, thank you for sharing!

FM Radio, the choice of an old generation (Hackaday)

Had the pandemic not upended many of this summer’s fun and games, many of my friends would have made a trip to the MCH hacker camp in the Netherlands earlier this month. I had an idea for a game for the event, a friend and I were going to secrete a set of those low-power FM transmitters as numbers stations around the camp for players to find and solve the numerical puzzles they would transmit. I even bought a few cheap FM transmitter modules from China for evaluation, and had some fun sending a chiptune Rick Astley across a housing estate in Northamptonshire.

To me as someone who grew up with FM radio and whose teen years played out to the sounds of BBC Radio 1 FM it made absolute sense to do a puzzle in this way, but it was my personal reminder of advancing years to find that some of my friends differed on the matter. Sure, they thought it was a great idea, but they gently reminded me that the kids don’t listen to any sort of conventional broadcast radio these days, instead they stream their music, so very few of them would have the means for listening to my numbers stations. Even for me it’s something I only use for BBC Radio 4 in the car, and to traverse the remainder of the FM dial is to hear a selection of easy listening, oldies, and classical music. It’s becoming an older person’s medium, and it’s inevitable that like AM before it, it will eventually wane.

There are two angles to this that might detain the casual hacker; first what it will mean from a broadcasting and radio spectrum perspective, and then how it is already influencing some of our projects. [Continue reading…]

New observations challenge popular radio burst model (Sky and Telescope)

Strange behavior caught by two radio observatories may send theorists back to the drawing board.

Fourteen years ago, the first fast radio burst (FRB) was discovered. By now, many hundreds of these energetic, millisecond-duration bursts from deep space have been detected (most of them by the CHIME radio observatory in British Columbia, Canada), but astronomers still struggle to explain their enigmatic properties. A new publication in this week’s Nature “adds a new piece to the puzzle,” says Victoria Kaspi (McGill University, Canada). “In this field of research, surprising twists are almost as common as new results.”

Most astronomers agree that FRBs are probably explosions on the surfaces of highly magnetized neutron stars (so-called magnetars). But it’s unclear why most FRBs appear to be one-off events, while others flare repeatedly. In some cases, these repeating bursts show signs of periodicity, and scientists had come up with an attractive model to explain this behavior, involving stellar winds in binary systems.

However, new observations by European radio telescopes may rule out this model.

Astronomers knew that FRB 20180916B, located in a galaxy some 475 million light-years away, produces multiple bursts about every 16 days, during a ‘window’ that lasts for a few days. “The idea was that the magnetar is part of a binary system with a 16.29-day period,” says Inés Pastor-Marazuela (University of Amsterdam), the first author of the new paper. If the companion star had a thick stellar wind that absorbs radio waves, the bursts would only be visible when the magnetar was on ‘our’ side of the orbit, she explains. [Continue reading…]

New WebSDR in Iceland (Southgate ARC)

Iceland’s IRA reports on August 24 Karl Georg Karlsson TF3CZ connected a new receiver over the internet covering 24-1800 MHz

A translation of the IRA post reads:

QTH is Perlan in Öskjuhlíð in Reykjavík. These are Airspy R2 SDR receivers for 24-1800 MHz (on VHF and UHF). The antenna is a Diamond D-190.

Karl Georg stated the following on FB:
The extension is not just for 2m, it can only be on one band at a time. So if one user switches, others who are connected also move between bands. (However, you can listen to each frequency within the same band). The receiver automatically tunes to APRS QRG 144.800 MHz, see the APRS website: http://SDR.ekkert.org/map

URL of the receiver
http://perlan.utvarp.com/#freq=24890000,mod=usb,sql=-150

Thanks to Karl Georg for his valuable contribution. This is an important addition for radio amateurs who experiment in these frequency ranges, as well as listeners and anyone interested in the spread of radio waves.

WZRH/KVDU Tower Destroyed By Hurricane Ida (Radio Insight)

The nearly 2000 foot tower utilized by Cumulus Media Alternative “Alt 92.3” WZRH LaPlace and iHeartMedia Variety Hits “104.1 The Spot” KVDU Houma LA was toppled by the winds of Hurricane Ida.

The 1999 foot structure was constructed in 1988 to host both signals. Only the bottom 150 to 200 feet remain standing. Both stations are licensed to operate with 100kW/591m, but have low powered auxiliary sites in downtown New Orleans. WZRH is located on the roof of Place St. Charles with 630w/200m. KVDU is on the Hancock Whitney Center with 1.2kW/220m.

In addition to KVDU, iHeartMedia Gospel 940 WYLD is silent at its cluster. The company reports that the remainder of its signals are now operational after all but 93.3 KQUE and 98.5 WYLD-FM were off the air on Monday.

Cumulus Media states that its entire cluster of WZRH, Adult R&B 102.9 KMEZ Belle Chasse, Country “106.1 Nash-FM” WRKN Picayune MS, and Hot AC “106.7 The Krewe” KKND Port Sulphur LA are off the air. [Continue reading…]
