Lemons into Lemonade: Nick is taking advantage of Texas power outage to play radio

Many thanks to SWLing Post contributor, Nick Booras, who writes:

I am stuck in the house in Texas, bored and with no power. So I decided to make a couple videos with my phone. One nice thing about a power outage… no RFI [Radio Frequency Interference].

This Icom 705 is an awesome radio! Perhaps your viewers might like these.

Thank you for sharing these, Nick! Yes, as we’ve noted before, power outages are an ideal time to play radio and indulge in a low-noise environment! And I agree with you: the IC-705 is a superb shortwave broadcast receiver.

I hope our readers in Texas will have power restored soon–this has been a rough week for many.

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 Mike, Troy Riedel, David Iurescia, and Bob Janney for the following tips:


Ham Radio Signals From Mars (Spaceweather.com)

Ham radio operators are doing something that until recently only big Deep Space Networks could do. “We’re monitoring spacecraft around Mars,” says Scott Tilley of Roberts Creek, British Columbia, who listened to China’s Tianwen-1 probe go into orbit on Feb. 10th. The signal, which Tilley picked up in his own backyard, was “loud and audible.” Click to listen:

The signal Tilley received from Tianwen-1 is dominated by a strong X-band carrier wave with weaker side bands containing the spacecraft’s state vector (position and velocity). Finding this narrow spike of information among all the possible frequencies of deep space communication was no easy task.

“It was a treasure hunt,” Tilley says. “Normally a mission like this would have its frequency published by the ITU (International Telecommunications Union). China did make a posting, but it was too vague for precise tuning. After Tianwen-1 was launched, observers scanned through 50MHz of spectrum and found the signal. Amateurs have tracked the mission ever since with great accuracy thanks to the decoded state vector from the probe itself.”[]

Open letter to PM, Ministers calls for international service to be strengthened, not cut (RCI Action Committee)

The following open letter was sent February 15, 2021 to Prime Minister Justin Trudeau, Deputy Prime Minister Chrystia Freeland, Foreign Affairs Minister Marc Garneau, and Canadian Heritage Minister Steven Guilbeault asking them to maintain the integrity of Canada’s Voice to the World, Radio Canada International (RCI).

Thirty-two signatories, including former Prime Minister Joe Clark, former Canadian ambassador to the United Nations Stephen Lewis, author-composer-songwriter-film director Richard Desjardins, author Naomi Klein, and actor Donald Sutherland, ask that the CBC/Radio-Canada policy announcement of December 3, 2020 be blocked, as well as any changes to RCI, until RCI staff, along with an assembled group of qualified people outside CBC/Radio-Canada, can propose a plan to rebuild the international service.

The signatories say the plan should devise a form of financial and editorial autonomy for RCI. And outline a path to follow to restore the international mandate and effectiveness of Radio Canada International in the context of today and the future.

Prominent Canadians rally to save Radio Canada International one more time (Toronto Star)

OTTAWA – A group of prominent Canadians is calling on the CBC to rethink its decision to significantly cut staff and rebrand the globally focused Radio Canada International to focus on domestic news.

Wojtek Gwiazda, spokesman for the group trying to save RCI, says the CBC is planning to cut 13 full-time staff and three contract jobs from a staff of about 20.

They’ve sent Prime Minister Justin Trudeau a letter signed by 32 prominent Canadians, including former prime minister Joe Clark, former Canadian ambassador to the United Nations Stephen Lewis, author Naomi Klein and actor Donald Sutherland asking for the decision to be reversed.

Gwiazda says the new CBC policy will focus almost exclusively on producing programming for ethnic communities and the ethnic media inside Canada, instead of directing programming to an international audience.

Gwiazda says the move is a violation of the Broadcasting Act and order-in-council that created RCI in 1945.

In the December memo to RCI staff, the CBC said it was “modernizing” the news service for the 21st century by offering more translated CBC content in new languages such as Punjabi and Tagalog, which is spoken in the Philippines.

“By becoming more relevant, more visible or more widely available in the languages spoken by the largest number of new Canadians, the new offering will allow Radio Canada International to better connect and engage with its target audience. RCI will also make all this content freely available to interested ethnic community media,” says the CBC statement.

RCI is used to fighting for its survival since the CBC cut its shortwave radio service in 2012, which severed the broadcaster from its Chinese audience, said Gwiazda.[]

Save and rave! How a compilation of pirate radio adverts captures a lost Britain (The Guardian)

Fashion boutiques, shop-fitters and others advertised alongside raves on early 1990s pirate radio. Now, a new compilation is rediscovering a slice of the underground

ave you got that record that goes ah-woo-ooo-ooh-yeah-yeah?” It’s a scene familiar to anyone who spent time in a hardcore rave record shop in the 1990s – a punter asking for a tune they’ve heard on pirate radio or at a rave but they don’t know the title of, so they mimic the riff or sample hook hoping someone behind the counter recognises it.

A relic of pre-Shazam life, the ritual is preserved in an advert for Music Power Records aired on the pirate station Pulse FM in 1992. Nick Power, owner of the north London shop, recalls that no matter how mangled the customer’s rendition, “nearly always, you’d be able to identify the exact record they were looking for”. In the advert, Power plays the roles of both sales assistant and punter, pinching his nose to alter his voice. Almost 40 years later, the comic skit commercial has been resurrected alongside others on two volumes of London Pirate Radio Adverts 1984-1993, by audio archivist Luke Owen. Power is pleasantly bemused by this turn of events: “I can’t see there’d be a demand for radio ads, but there’s got to be someone out there who’s interested enough to buy it. I don’t see it being a platinum release, though!”

Released via his label Death Is Not the End, Vol 1 is available digitally at a name-your-price rate and for £7.50 as a limited-edition cassette tape – an echo of the format on which pirate listeners captured transmissions of hardcore and jungle. Back then, most fans pressed pause when the ad break started, which means that surviving documents of the form are relatively scarce. But what once seemed ephemeral and irritating has acquired period charm and collectability.[]

A preliminary look at the Tecsun TU-80 FM Tuner

Many thanks to SWLing Post contributor, Mei Tao, who writes:

Hi Thomas:

I saw one reader had asked about Tecsun TU-80 FM Tuner several days ago, Fortunately, I have had this machine for only a couple of weeks.

Tecsun’s Chairman, Mr Liang Wei has told us that TU-80 was not designed for the pure Bclers not for the pure audiophiles either, but for the person who is both Bcler and audiophile. We have to use it with high quality external speakers. That’s it.

Let me show you some pictures I took yesterday:

Additionally, one reader misunderstood me as a seller, absolutely no, I am just a radio enthusiast and a college teacher, I major in western philosophy, especially American Pragamatism.

Yours sincerely.

Mei Tao

Thank you, Mei Tao. We truly appreciate your early access to these various models of portable radios. The TU-80 appears to be a truly unique model and I’m sure FM DXers are following it carefully. Thanks again!

Thank you, Mei Toa! The HRD-747 certainly offers a wider frequency range that we’re used to seeing in small portable radios. I’m very curious how sensitive and selective it is in those higher VHF/UHF bands and if imaging or poor selectivity are issues.

Thank you so much for the preliminary info!

Desheng retailing the Tecsun H-501 at 1500 Yuan

Many thanks to SWLing Post contributor, Robert Richmond, who writes:

You probably have seen the info months ago, but I just noted Tecsun China has officially launched the Tecsun H-501 receiver in China priced at 1500 Yuan, which is about $230 USD. Add shipping.

The Chinese domestic market H-501 model on AliExpress and Bangood has been averaging $400+ USD. I have no idea if the Desheng/Tecsun store ships outside China, but it seems like a considerable savings for customers outside of China if actually capable of ordering there.

The Tecsun homage currently features a H-501 banner:

The homepage link for more info takes you to a Desheng/Tecsun sales page including specs, multiple pics, consumer reviews, etc. here:

Best Regards,

Robert Richmond

Thank you for the tip, Robert! I’ll be waiting for Anon-Co to distribute the export version of the H-501, but the 1500 Yuan/$230 USD price point is much closer to what I expected rather than those early inflated AliExpress prices.  Thanks again!

Frank’s advice for dealing with SDR clones

Many thanks to SWLing Post contributor, Frank Howell (K4FMH), who shares the following post published on AmateurRadio.com:

Many of us hams, SWLs, and makers buy inexpensive electronics from China. It’s become a bonanza for small, cheap and surprisingly good radio-related gadgets and parts on eBay and other vendors. I buy a fair amount, most recently a recommended project box for a set of HF bandpass filters I purchased from a small company in Australia. It finally arrived and is superb for a very cheap price!

But there’s a dark side. I love a bargain more than most. But when it’s an illegitimate clone of another genuine manufacturer’s product, that’s no fair. Yep, there’s ways to legitimately copy another design with various hardware licenses and beaucoup software licenses (if that’s relevant to the product). One of the ongoing issues in the Pacific Rim to the rest of the world has been the taking of the intellectual property from others, making a cheaper product offered for sale, and using the trade naming and hardware/software designs of the originating manufacturer. In short, stealing for profit.

So be careful. The fake copies may not work with the latest SDRplay software including SDRuno. There will be no technical support even if you get some limited functionality using out of date software.

Jon Hudson SDRPlay.com

For those in or interested in the SDR receivers available, there are a number of prominent names. I’ve had an Italian Perseus SDR for over a decade. Paid the asking price (a lot by today’s standards). It’s a terrific product although aging in the technology of the design. The SDRPlay company in England has risen to the top in terms of performance, continued innovation and the software they purchased for a free download to their legitimate customers. SDRUno is a terrific software package which they continue to update. They have an API so other software makers (like Simon Brown with SDR Console) can drive the SDR car, too. Their price points are very good and appropriate for the various receiver models they have on the market. A third-party individual has written code for a continually updated package that implements a Spectrum Analyser for most of the SDRPlay receivers. I’ve used an old (no longer in production) RSP1 with it and it’s very cool! And don’t get me started on their tech support and education. Mike Ladd KD2KOG is the Dude on social media for SDRPlay and related products. Mike creates new markets for SDRPlay products by educating hams and listeners on creative new ways to use them.

Individual preferences for one SDR product or another aside, SDRPlay is a legitimate company that plays more than fair in the marketplace. They do a lot to support the various elements of the radio hobby that we all enjoy. We should return that favor so that they can continue without the eroding effects of illegal clones undercutting their market, n’est-ce pas?

Continue reading Frank’s article at AmateurRadio.com where he describes how to report a clone to eBay…

Thank you for sharing this, Frank.

I’m with you. While I love saving money, I also enjoy supporting companies who innovate and invest in our radio world. SDRplay is a top-shelf company and, along with Airspy, have made high-performance SDRs affordable for everyone. When you buy from SDRplay and Airspy or one of their authorized distributors, you’re investing in the company and their ability to fund research and development. When you buy a clone, you’re lining the pockets of a manufacturer who copies from industry leaders and has no interest in innovating or even supporting radio enthusiasts over the long haul. It’s merely a profit opportunity for them built on the hard work of others.

Plus, SDRplay and Airspy SDRs are so affordable, how much are you really saving by buying a clone? $25-50? That savings will disappear when SDRuno and SDR# develop new app tools that leave a clone behind.

I know of a number of readers who have purchased SDRs without realizing they were buying clones. Don’t be too frustrated–it happens because the market is so saturated with clones. Next time you purchase, however, go straight to the source!

I have no respect for clones and that’s why I don’t actively link to clone products like the Malahit/Malachite variants or MSI.SDR.  Believe it or not, some of these are actually clones of clones!

Consider purchasing from companies and retailers who invest and innovate in our radio space. Skip the clones.
