13dka Reviews: The new 2022 “Belka” (generation 3) general coverage receiver

The new 2022 “Belka” (generation 3) general coverage receiver

by 13dka

Since its introduction in 2019, the super-tiny Belka (back then called “Belka DSP”) shortwave receiver sure gained an enthusiastic followership among SWLs and hams. The main reason for this is certainly the way how the Belka is incredibly small yet playing in a different league than the various consumer grade, Chinese mass-production radios, particularly the DSP-based ultraportables: The Belka is an all-mode shortwave communications receiver with a completely different (direct conversion SDR) architecture, developed and produced by a radio enthusiast (Alex, EU1ME) in a small mom&pop shop in Belarus.

In case you’ve never heard about it amidst all the buzz about more popular brands, here’s the skinny:

The Belka offers true allmode (including NFM and CW) reception with a proper 400 Hz CW filter and individual settings for the low and high filter slopes for AM, FM and SSB. It has an AM sync detector and comes with a 0.5ppm TCXO-controlled local oscillator for absolutely spot-on, calibration-free frequency precision and stability, which makes SSB or ECSS reception of broadcast stations a pure joy. The second iteration “Belka DX” brought a slightly extended coverage down to 1.5 MHz and an I/Q output for panadapter display and/or processing via your favorite SDR software.

All Belkas are quiet and very sensitive radios with a surprisingly robust front end, the filters are better and its AGC works like you’d expect it from a communications receiver, without the artifacts and distortion the DSP radios are infamous for, and of course smooth, non-“muting” tuning in variable steps down to 10Hz.

The Belkas have no built-in speaker (available as option tho) but really excellent audio on headphones and external speakers and they actually give my Icom IC-705 a run for its money in terms of reception quality, and they do that for up to 24 hours on a single charge of the internal Li-Ion battery. This stunning feature set is crowned by the best performance on a telescopic whip antenna ever – the Belkas have a high-impedance (>10 kOhm) antenna input optimized for this whip and taking it on a walk is (really!) like having a big rig with a big antenna in tow…

Despite all this goodness setting the Belka(s) quite fundamentally apart from most (if not all) current and former, even much higher priced portables and simultaneously putting it solidly into pricey tabletop territory, it hasn’t put Tecsun et al out of business for a couple of reasons: One reason is that it can only be obtained from Alex in Belarus, which is now often assumed to be impossible (it isn’t, more on that later). Another reason is that it doesn’t try to compete with aforementioned multiband radios from China, so there is no FM broadcast band and – until now – no AM BC band, but most owners and potential buyers particularly in the US really wished it had at least the latter. Well, Alex obviously heard us! After the Belka DSP and the Belka DX, the new Belka is just called “Belka”, so in order to avoid any ambiguity I’m going to refer to this model as “Belka 2022”.

What’s new?

The most prominent addition to the Belka 2022 is the extended 0.1-31 MHz coverage, the previous version only started receiving at 1.5 MHz. With LW and MW included, its “pseudosynchronous” detector (as featured in venerable radios from Harris, Racal or Drake), the great filtering and the great frequency precision for hassle-free ECSS reception are promising that the “squirrel” is now an ultra-ultraportable companion for MW DXers as well.

C.Crane’s new CC Skywave SSB 2

If, like me, you received your latest C.Crane catalog, you’ve no doubt noticed the new C.Crane CC Skywave SSB 2 on page 3.

The CC Skywave SSB is one of my favorite all-time travel portables. I love it for its versatility, frequency coverage, and overall performance. Click here to read my review.

Version 2 of the Skywave SSB includes the following upgrades per C.Crane:

The new The Skywave SSB 2 has several improvements: The new Shortwave antenna jack can significantly improve SW reception when used with an external antenna. The new micro-USB connector now works well from any USB port along with improved in-circuit battery charging for optional “AA” NiMH rechargeable batteries. Other upgrades include a higher quality speaker along with slightly more audio amplification. Longer feet on the bottom of the radio for better stability.

All of these are welcome iterative upgrades. I especially love any improvement to the built-in speaker–travel portables are small, so any speaker improvements are most welcome.

Here’s the full copy from their catalog:

We will plan to review the Skywave SSB 2, of course! Stay tuned!

Alex shares details about the latest Belka portable and upgrades

After posting information about the new Belka upgrades yesterday, Belka designer, Aleksandr Buevskiy, reached out to me and shared the following details and clarification about the latest design: 

I would like to share some more details/photos about Belka so that there is clear understanding of what features the new version has.

First, regarding its name. Now there’s no “DX”, “DSP” or something else. Belka is just named “Belka”. As simple as that 🙂

Second, frequency range was extended with the same parameters and performance. It’s now 0,1-31 MHz.

In previous versions there were 32 memory cells, we’ve now added a few more – 36 is exact number now to be precise.

One more thing about memory cells is that now there is a possibility to listen to memory cells before loading. See attached how it looks like (I’ve added video illustrating memory cells listening just because there were questions).

I also attach several photos of new version and add block diagram. You’ll find attached also PCB photo of new version:

Cheers,
Alex
EU1ME

Thank you for sharing all of this detail, Alex. I believe your new Belka will be a hit! I’m sure readers reach out with their reviews and we will share them here on the SWLing Post!

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….
