Egil is pleased with his new Belka-DX and Tecsun ICR-100 cases
Many thanks to SWLing Post contributor, Egil (LA2PJ), who writes:
Hi Thomas,
In the middle of march, Steve Allen (KZ4TN) posted this article showing a case for the BELKA-DX.
I found his idea so good that I ordered two of the small boxes, using the Amazon link given in his article.
The boxes arrived here in Norway just twelve days after ordering, and was delivered to my door by a local transporter.
Never before have I experienced that kind of service on any purchase via Amazon!
While packing the BELKA-DX in one of the boxes, I discovered that my Tecsun ICR-100 speaker/audio recorder fit snugly in the other box. The two boxes also contains a six meters long wire antenna, charging cables for both units, earphones, and even an USB charger, just in case I get the opportunity to recharge the batteries.
The attached pictures show my new setup. Two items are not shown in that picture: a wire antenna plus a 20Ah powerbank from Anderson. We are going to an off grid cabin for the Easter holidays, and hope that when leaving home with everything fully charged, the powerbank will keep this setup plus my smartphone happy for a whole week.
73s Egil – LA2PJ
Thank you so much for sharing this, Egil! It’s absolutely amazing that the shipping service to Norway was so efficient.
I think you’ll have no problem at all enjoying hours upon hours of DXing with the Belka-DX in your off-grid cabin. No doubt you’ll be escaping the RFI and enjoying much lower noise floors while on vacation–this will give you an opportunity to truly take advantage of the Belka-DX receiver. You’ll have to report back with your experience and photos (hint, hint!).
You and the ionosphere: Share your propagation stories!

You and the ionosphere . . . a reader participation post
By Jock Elliott, KB2GOM
Here’s a shocker for you: we live at the bottom of the sky. Above us there are multiple layers of the atmosphere, pressing down on us at 14.7 pounds per square inch.
Of particular relevance to us as shortwave listeners and hams, there is a special layer of the atmosphere, not shown on the chart above called the ionosphere. The ionosphere starts around 30 miles above us and extends up to about 600 miles and includes parts of the layers above.
The Sun’s upper atmosphere, the corona, is very hot and produces a constant stream of Ultra-Violet and X-rays, some of which reach our atmosphere. When the high energy UV and X-rays strike the atmosphere, electrons are knocked loose from their parent atoms and molecules, creating a layer of electrons.
Now, here’s the cool part: this layer – the ionosphere – is important because radio waves bounce off of it.
The sun, however, is not constant in its action on the ionosphere. The amount of UV and x-ray energy (photon flux) produced by the sun varies at by nearly a factor of ten as the sun goes through an 11 year cycle. The density of the ionosphere changes accordingly, and so does the ability of the ionosphere to bounce radio waves. When the sun is at peak activity, and the ionosphere is “hot,” SWLs and hams are likely to experience excellent long-range propagation. When the sun is quieter, long-range propagation diminishes.
Every 11-year solar cycle is unique, but early indications are that we may on the verge a cycle that favors long-range propagation: https://swling.com/blog/2022/03/termination-event-may-indicate-solar-cycle-strength/
The results can be spectacular. Decades ago, during a particularly hot solar cycle, I once spoke from my station near Albany, NY, to a station in the state of Georgia on a mere 4 watts. On another occasion, I conversed with a ham in Christchurch, New Zealand – a distance of over 9,000 miles – with 100 watts single sideband transmit power. During that same period, I would routinely listen to shortwave stations halfway around the world.
And now, it’s your turn – what’s your favorite long-range propagation story, either as an SWL or ham? Please comment!
Antiques Roadshow Radio and “The changing sound of radio”
Many thanks to SWLing Post contributor, Pete Madtone, who writes:
[L]ast night while I was having my dinner, a lovely Marconi crystal set came on Antiques Roadshow that a chap had rescued from a skip! In the end it was valued for £1000-£1500. A sort of radio you’d love in a museum cabinet at home.
Nice pics of radio in that time too in the little piece.

[Also,] I just got a recommendation about a wonderful series on the BBC called The changing sound of radio with Chris Watson (wildlife sound recordist and original member of Cabaret Voltaire). The first one is all about recording natural sounds which is wonderful but episode 2 has shortwave radio, binaural sound and tape loops in music. It is very very interesting!

Thank you so much for these tips, Pete!

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!
Good news for Pacific regional broadcasting – bad news for locals (Asia Pacific Report)
Good news — an Australian parliamentary review recommends a more “expansive” media presence in the Pacific.
Bad news — little of that expansion envisions a role for island media.
Instead, the committee endorsed a proposal for “consultation” and the establishment of an independent “platform neutral” media corporation, versus the existing “broadcasting” organisation.
That proposal was among several points raised at two public hearings and nine written submissions as part of Australia’s “Pacific Step Up” programme, aimed at countering the growing regional influence of China.
Former long-time Pacific correspondent Sean Dorney last month told the Joint Standing Committee on Foreign Affairs, Defence and Trade that Australia was previously leading regional media spaces.
“But the vacant space that was left there when Australia Network disappeared, as people have said, has really been taken over by China,” he said.
“Throughout my time as the Pacific correspondent for the ABC, I saw this Chinese influence growing everywhere.”
[…]Taking up ten of 176 pages, the report’s media section is nonetheless seen as relatively comprehensive compared with the dismantling of broadcasting capacity in recent years.
This includes the literal dismantling of shortwave equipment in Australia despite wide protest from the Pacific region.
Nearly three years previously, a 2019 Pacific Media Summit heard that discontinuation of the shortwave service would save Australia some $2.8 million in power costs.
A suggestion from a delegate that that amount could be spent on $100,000 for reporters in each of 26 island states and territories was met with silence from ABC representatives at the summit.
However, funding would be dramatically expanded if the government takes up suggestions from the submissions to the joint committee. [Continue reading the full article…]
Pay Your Respects To Radio, The Ancestor Of Podcasting (Rolling Stone)
In the 1890s, Italian inventor Guglielmo Marconi left a lasting legacy when he sent a wireless telegraph message via Morse Code to a recipient. By the turn of the 1900s, Marconi’s innovation would give rise to an entirely new industry, one focused on creating new ways for people to communicate even across vast distances: radio.
Throughout the first half of the 20th century, radio would not only play a major role in the international correspondence of countries fighting in both World Wars but it also became a widely popular phenomenon amongst the general public. By the mid-1920s, there were hundreds of licensed radio stations hosting news broadcasts, comedy shows, dramas, live music, sports programs and other forms of entertainment.
A century later, it’s not hard to spot the parallels between what made radio one of the most popular content mediums in history and the explosive growth of radio’s evolution in podcasting. Though there are some unique differences between the two mediums, I believe podcasters should still pay respect to how the evolution of radio gave rise to the advent of podcasting.
The Rise of Contemporary Audio Entertainment
On October 30, 1938 — the evening before Halloween — Orsen Welles hosted a radio adaptation of H.G. Wells’s science fiction novel, The War of the Worlds, “converting the 40-year-old novel into fake news bulletins describing a Martian invasion of New Jersey.” While Welles and his team reportedly had no intention to deceive listeners into believing the broadcast was in any way real, Welles would later go on to say in a 1960 court disposition about his desire to release the broadcast, “in such a manner that a crisis would actually seem to be happening…and would be broadcast in such a dramatized form as to appear to be a real event taking place at that time, rather than a mere radio play.” [Continue reading at Rolling Stone…]
Why Russian radios in Ukraine are getting spammed with heavy metal (The Economist)
Ukrainians are eavesdropping on the invaders and broadcasting on their frequencies
One of the many surprising failures of the Russian invasion force in Ukraine has been in radio communications. There have been stories of troops resorting to commercial walkie-talkies and Ukrainians intercepting their frequencies. This may not sound as serious as a lack of modern tanks or missiles, but it helps explain why Russian forces seem poorly co-ordinated, are falling victim to ambushes and have lost so many troops, reportedly including seven generals. What is going wrong with Russian radios? Continue reading
Wireless Flirt episode explores shortwave radio
I’m very honored to have been interviewed by John Walsh who produces the excellent program Wireless on Flirt FM in Ireland. John reached out to discuss the relevance of the shortwave radio medium, particularly through the context of the Russian invasion of Ukraine. Here’s the show description:
In the April 2022 edition of Wireless, we look at the part of the radio spectrum called shortwave, consider its importance in the past and continued relevance in a digital world. Founder of the SWLing blog Thomas Witherspoon discusses the historical development of shortwave, including its heyday during the Cold War, and explains how it continues to be used today, for instance to evade Russian internet censorship during the Ukrainian war. The programme also remembers Irish pirate shortwave operators of the 1980s as featured on our related site Pirate.ie.
Click here to listen to the full show at Wireless Flirt.
John is a true kindred spirit and devoted radio enthusiast. I would encourage you to subscribe to his monthly Wireless episodes via your favorite podcast player; here are links to iTunes, Spotify, and Stitcher.
In addition, John is the one of the founders and curators of Pirate.ie which is a brilliantly documented archive of pirate radio stations in Ireland. I highly recommend checking it out!
