Radio Waves: AM/FM Receiver Sales Stabilize, Asheville Radio Museum Adds Model HS2, Legacy remains of WSY, and Farewell to WCFW

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


AM/FM Receiver Sales Have ‘Stabilized’ Even As Audio Turns Up On More Devices. (Inside Radio)

Anyone who has tried to find an AM/FM receiver in a big box retailer knows they are not as easy to find as they once were. It is little surprise then that the Consumer Technology Association expects fewer to sell this year. But at roughly five million units now sold each year, CTA expects that number to hold steady in the years to come, in part due to the role radio plays during emergencies.

“That category has stabilized,” said Rick Kowalski, Director of Industry Analysis and Business Intelligence at CTA. “It’s a low number relative to other categories, but there’s a steady demand, just in terms of people having an AM/FM radio for those situations where you might need a battery-powered radio as a backup.”

CTA forecasts 4.7 million traditional radio receivers will be sold this year in the U.S. That is six percent lower than the five million units sold in 2021. “Looking out in the next five years. It’s not going to get much lower than that,” Kowalski said in an interview.

CTA projects 24.5 million smart speakers will sell this year, or roughly five-times as many as traditional radio receivers. But in what may be a surprise to many, that estimate is actually two percent lower than the 25 million smart speakers that CTA says were sold last year. [Continue reading…]

“Bringing it home” Asheville Radio Museum adds local piece of history to its collection (WLOS)

ASHEVILLE, N.C. (WLOS) — The Asheville Radio Museum has added a new piece of history to its’ collection!

It’s a 1922 radio receiver built by an Asheville-based business.

The model HS2 radio the museum procured is only one of two known to exist.

Collector and restorer Robert Lozier found that it was the first name brand radio built in North Carolina.

News 13 spoke to the director of media communications Peter Abzug about why this radio is so significant.

“Having this radio here, in Asheville, where it was built is really significant,” he said. “It’s bringing it home. Although the company itself didn’t last for years and years, it did employ people and it was a significant part of Asheville’s history, and something we can be very proud of.”

Legacy remains of WSY, Alabama’s first radio station (Alabama News Center)

Innovation is at the historic heart of Alabama Power, beginning with its founding in 1906 and Capt. William Patrick Lay’s vision of electrifying the state by harnessing the power of Alabama’s rivers.

But the company’s embrace of another cutting-edge technology, just 16 years after Alabama Power’s incorporation, is also historic.

One hundred years ago this year, on April 24, 1922, Alabama Power hit the airwaves with the state’s first operating radio station. WSY (an acronym for “We Serve You”) began broadcasting from rented space in a building on Powell Avenue in Birmingham.

The 500-watt AM station was initially designed as a company tool, to provide better communications among employees – especially those in the field and at remote generating plants. In fact, radio technology was so new – regularly scheduled radio programming in the United States started only in 1920 – Alabama Power engineers had to design and build most of WSY’s transmitting equipment.

“We began assembling the set … with intentions of using it for purposes of operation of the system exclusively,” wrote George Miller, the employee in charge of the station, in the July 1922 issue of the company’s Powergrams. “The broadcast feature came up, though, and materially changed our plans.”

Indeed, a month before the station went on the air, The Birmingham News published a do-it-yourself piece about “how to make your own radiophone receiving set” so local residents could pick up WSY when it began broadcasting.

Interest in the station was so strong that within weeks it began offering entertainment programs, according to “Developed for the Service of Alabama,” the centennial history of Alabama Power, written by noted historian Leah Rawls Atkins.

Dee Haynes, with the Alabama Historical Radio Society, recalled one story that underscores WSY’s popular embrace. Soon after WSY went on the air, earpieces began disappearing from the handsets of payphones all over Birmingham, apparently because people were swiping them to use in home-built receiving sets.

FAREWELL TO FM: A Grandson’s Recollections of His Family’s Legacy Radio Station, WCFW (Volume One)

For 54 years, WCFW has been a beloved independently owned radio station on 105.7FM. But for lifelong Eau Claire resident Parker Reed, it has been more than that: it’s his family’s life, love, and legacy.

A catchy jingle – featuring the melody “WCFW, where FM means fine music” – came across a young radio station owner’s desk in 1969.

It was short, simple, and it worked. The owner paid $25 for it, and more than 50 years later that same jingle – which has aired thousands of times on 105.7FM radio – exemplifies the values of WCFW in Chippewa Falls and the couple who have owned it for over half a century: simplicity and consistency.

My grandparents, Roland and Patricia Bushland, have owned and operated WCFW since its inaugural broadcast on the airwaves on Oct. 20, 1968. Earlier this summer, they decided to end their 54-year stint in radio, selling the legacy station to Magnum Media – a Wisconsin-based media organization owned by Dave Magnum who now owns 25 radio stations across the state and will take over operations of the quaint, easy-listening station later this fall.

It’s a bittersweet moment – for the community, yes, but especially for our family, for whom the station has been an integral part of our lives for decades.

“It’s hard to not have mixed feelings about it, because it was our life for so long,” said my grandmother, Patricia Bushland. “When you start something, and you’re the only people who ran it all those years, you get attached to it. But after so many years, I’m thrilled to death that someone new is coming in, and we can finally take a break.”

When my grandfather, Roland, was young, he would draw pictures of radio towers during school – as his life too began with radio, front and center. My great-grandfather Roy Bushland owned and operated multiple Bushland Radio Specialties storefronts in Chippewa Falls and Eau Claire since the early 1930s – a business where my grandfather got his start in 1952 after he graduated Chippewa Falls High School as salutatorian. [Continue reading…]

Eton Elite Satellite Update (August 20, 2022)

Eton Elite Satellit HD

Eton Elite Satellit Update (August 20, 2022)

As many SWLing Post readers have pointed out, Universal Radio has posted the following update to their product page for the Elite Satellit:

Our initial allocation of radios arrived 08/17/22. Our Q/C testing detected a problem with the radio. We are working closely with Eton to find a solution to the issue. We will begin shipping radios as soon we are satisfied the radio fully meets specifications.

Some early adopters noted that the receiver controls freeze when engaging HD radio stations. We suspect this may be one of the issues.

Universal Radio will no doubt post updates as soon as they’re available. For now, though, they are not shipping the Eton Elite Satellit. We assume this will be the case for other retailers as well.

Introducing the amazing SULA: An affordable unidirectional DX-grade loop antenna that you can build!

Many thanks to SWLing Post contributor extraordinaire, 13dka, who brings us a three part series about the new SULA homebrew antenna project. This first article describes this affordable antenna and demonstrates its unique reception properties. The second article will focus on construction notes. The third and final article will essentially be a Q&A about the SULA antenna. All articles will eventually link to each other once published.

This wideband unidirectional antenna is an outstanding and innovative development for the portable DXer. I love the fact that it came to fruition via a collaboration between Grayhat and 13dka: two amazing gents and radio ambassadors on our SWLing.net discussion board and here on the SWLing Post. So many thanks to both of them!

Introducing the Small Unidirectional Loop Antenna (SULA) 1-30MHz

A small and simple, unidirectional and DX-capable loop “beam” for SWLs!

by 13dka

In early June, Andrew (grayhat), SWLing Post‘s resident antenna wizard suggested a variation of the “cardioid loop” on the SWLing Post message board: The original “cardioid loop” is a small loop receiving antenna deriving its name from a cardioid shaped (unidirectional) radiation footprint. The design is strikingly simple but it has a few downsides: It relies on a custom preamp, it needs a ground rod to work and it is unidirectional only up to 8 MHz.

Andrew’s version had the components all shuffled around and it did not only lose the ground rod, it also promised a nice cardioid pattern over the entire shortwave, from a small, diamond shaped loop. Wait…what? It can be made using parts available on Amazon and your DIY store:

You need some 3m wire and PVC tubes to create a support structure to hold the wire, a 530 Ohm resistor and a 9:1 balun like the popular “NooElec One Nine”. Since it’s a “lossy” design, adding a generic LNA like the NooElec “LANA HF” would help getting most out of it. When you put that all together you have what sounds like an old shortwave listener’s dream: a small, portable, tangible, and completely practical allband shortwave reception beam antenna with some more convenient properties on top, for example, it is a bit afraid of heights.

That sounded both interesting and plain crazy, but the .nec files Andrew posted were clearly saying that this antenna is a thing now. Unfortunately Andrew suffered a little injury that kept him from making one of those right away, I on the other hand had almost all the needed parts in a drawer so I ended up making a prototype and putting it through some of its paces, with Andrew changing the design and me changing the actual antenna accordingly, then mounting it upside down. Let me show you around:

  •  Small, diamond shaped wire loop (with 76cm/29.92″ sides), needing as little space as most other small loops.
  • Unidirectional with a ~160° wide “beam” and one pronounced minimum with a front/back-ratio of typically 20dB over the entire reception range 1-30MHz.
  • Moderate height requirements: It works best up to 3m/10′ above ground, where it gives you…
  • …a main lobe with a convenient flat takeoff angle for DX
  • Antenna is comparatively insensitive to ground quality/conductivity.
  • Wideband design, works best on shortwave and is pretty good up to 70cm.

A functional small beam antenna for shortwave reception that’s just as small and possibly even more lightweight (prototype:~250g/9oz) than your regular SML, that can be easily made out of easy to obtain parts and easily carried around for mobile/portable DXing and due to its cardioid shaped directional pattern also for direction finding, a “tactical” antenna that’s also doing DX? Unlike conventional, Yagi-Uda or wire beams it can achieve a low takeoff angle at only 3m/10ft height or less, the front/back ratio is typically better than that of a 3-element Yagi, with a particularly useful horizontal pattern shape. That it’s rather indifferent to soil quality could mean that more people get to reproduce the good results and being a real wideband antenna is making the SULA an interesting companion for multiband radios and SDRs. Really? A miracle antenna? Is it that time of year again? If I had a dollar for every….

Eton Elite Satellit HD Receivers – Now Shipping

Eton Elite Satellit HD

Thanks to commenter Keith on my “Consistently Inconsistent” article, we learn that the Eton Elite Satellit HD receiver is now shipping. Keith purchased the receiver from Amazon.com and is expecting delivery on August 18.

Note that over the half-hour it took me to write this update article, Amazon’s stock of the Elite Satellit HD dropped from 19 to 10!

There are also updates on availability found on three other web sites:

  • Eton Corporation: No longer does their page say “Arriving this month – reserve yours today!”. Instead, the radio is shown as “available today!”
  • Hammacher Schlemmer: their web page indicates “In stock – available for immediate shipment”.   EDIT: Wow, that was quick! Just after I posted this article, HS changed their web page to “We regret that this item is no longer available”.
  • Universal Radio: Gone is the “available late August” statement, and the radio is available for adding to your shopping cart and checkout.

This is great news for those who have awaited the receiver since its announcement in 2019, and especially for those getting the radio at the original pre-order price (myself included :^)

Keith, thanks again for the heads-up on your Elite Satellit HD order. Please leave some first impression comments when you receive it!

Radio Waves: US Emergency Alert System Vulnerabilities, Tape Measure Antennas, Eight Year Old Chats with ISS, and Power of Prison Radio

Radio Waves:  Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


“Huge flaw” threatens US emergency alert system, DHS researcher warns (ARS Technica)

Hackers can disrupt legit warnings or issue fake ones of their own.

The US Department of Homeland Security is warning of vulnerabilities in the nation’s emergency broadcast network that makes it possible for hackers to issue bogus warnings over radio and TV stations.

“We recently became aware of certain vulnerabilities in EAS encoder/decoder devices that, if not updated to the most recent software versions, could allow an actor to issue EAS alerts over the host infrastructure (TV, radio, cable network),” the DHS’s Federal Emergency Management Agency (FEMA) warned. “This exploit was successfully demonstrated by Ken Pyle, a security researcher at CYBIR.com, and may be presented as a proof of concept at the upcoming DEFCON 2022 conference in Las Vegas, August 11-14.”

Pyle told reporters at CNN and Bleeping Computer that the vulnerabilities reside in the Monroe Electronics R189 One-Net DASDEC EAS, an emergency alert system encoder and decoder. TV and radio stations use the equipment to transmit emergency alerts. The researcher told Bleeping Computer that “multiple vulnerabilities and issues (confirmed by other researchers) haven’t been patched for several years and snowballed into a huge flaw.”

“When asked what can be done after successful exploitation, Pyle said: ‘I can easily obtain access to the credentials, certs, devices, exploit the web server, send fake alerts via crafts message, have them valid / pre-empting signals at will. I can also lock legitimate users out when I do, neutralizing or disabling a response,’” Bleeping Computer added. [Continue reading…]

Just how good is a tape measure antenna anyway? (Hackaday)

Amateur radio operators have played a longstanding game of “Will It Antenna?” If there’s something even marginally conductive and remotely resonant, a ham has probably tried to make an antenna out of it. Some of these expedient antennas actually turn out to be surprisingly effective, but as we can see from this in-depth analysis of the characteristics of tape measure antennas, a lot of that is probably down to luck.

At first glance, tape measure antennas seem to have a lot going for them (just for clarification, most tape measure antennas use only the spring steel blade of a tape measure, not the case or retraction mechanism — although we have seen that done.) Tape measures can be rolled up or folded down for storage, and they’ll spring back out when released to form a stiff, mostly self-supporting structure.

But [fvfilippetti] suspected that tape measures might have some electrical drawbacks, thanks to the skin effect. That’s the tendency for current to flow on the outside of a conductor, which at lower frequencies on conductors with a round cross-section turns out to be not a huge problem.

Broadstairs eight-year-old to feature on NASA website after radio chat with ISS astronaut (The Isle of Thanet News)

A Broadstairs eight-year-old has chatted with an astronaut aboard the International Space Station and a recording of the conversation will feature on the NASA website.

Isabella Payne spoke to Astronaut Kjell Lindgren as the ISS flew overhead last week.

The youngster was with dad Matthew who is a license holding amateur radio enthusiast and tutor. He and Isabella are both members of Hilderstone Radio Society.

Matthew said: “Isabella has been a member of the radio club ever since she was born and has been playing with the radio since she was six. Because I have the full licence she can sit on my knee and use the radio to speak to people as long as I am controlling it. Everyone at the club can do that. She has been involved in a few radio events, Children On The Air events, and will hopefully go for her own licence soon. [Click here to read the full article and view the photos.]

The power of prison radio in giving voice to the voiceless around the world (ABC)

“I plan my life by the radio these days, my contact with the outside world in a sense…”

The first ever international prison radio conference has just been held in Norway, bringing together representatives of prison radio shows from 19 countries, including Australia, where Indigenous people continue to be grossly over-represented in prison populations.

Prison radio shows, wherever they are in the world, all work to give voice to the voiceless and empower people by enabling them to tell their own stories.

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

The Erres KY-418 Radio set assembly line. You must watch this:

Click here to view on YouTube.

My heart goes to the poor guys who work under all that machinery noise with no ear plugs or with no mask when spray paint.

Everything is hand made in-house even the loudspeakers, coils or the rotary switches….

Just remember that WWII is on while it was made and I don’t think the KY-418 was a cheap radio…

Regards, Adi

Thank you for sharing this, Adid. You’re right: there were a few generations of folks who lost much of their hearing early on due to the constant noise on factory floors. 

That said, I’ve been enjoying these videos of early radio production lines. Thank you!
