A case for the Belka-DX and cautionary tale!

My Belka-DX: A Cautionary Tale

One of the most amazing SW radios I have ever owned and listened to is the Belka-DX. Its size to performance ratio is without equal, IMHO.

Late last year I dropped it on the floor and was emotionally traumatized when I picked it up and found the LCD to be broken (see photo above). It still received but most of the display was damaged and not readable. I tried to open it up with the intent of replacing the LCD myself (if I could source one) but I could not figure out how to remove the circuit board.

I contacted Boris at MobiMax in Bulgaria from whom I purchased the little squirrel. It took a few weeks of back and forth as he worked to get pricing for the replacement LCD. Eventually he had a very reasonable quote put together and I mailed the Belka-DX off to Bulgaria. Now the wait began. It took almost four weeks for it to finally arrive at MobiMax. Boris had the repair turned around in about a week and I made payment via PayPal. Just like before it took about four weeks transit time and I worried that it would disappear somewhere on the way.

It arrived safe and sound and I am very glad to have it back. I’ve been missing my bedtime SWLing.

So…moving forward I will now always store the radio in a hard case. After digging around in my box of assorted cases I found nothing that was the right size.

After twenty minutes on Amazon I found a hard case that was originally for a small point and shoot digital camera. It was a bit larger than the Belka-DX and it also had room for earbuds, the charging cable and power adaptor, and a small wire antenna.

I glued some foam in the case to hold the radio in place and it’s now nice and snug.

Now I can safely carry it in my daypack or other travel luggage without fear of damage.

“It’s magic, but it’s real”: The joys of listening to the ham bands

The joys of listening to the ham bands

By Jock Elliott, KB2GOM

            “It’s magic, but it’s real.” That statement was uttered recently by an amateur radio operator – a ham – from South Carolina. He was on the 20-meter band (around 14,187 USB), operating in upper sideband (USB), chatting with a British ham from the Isle of Wight off the coast of England, and another US ham located about 60 miles south of Chicago, Illinois.

The South Carolina ham was expressing his delight that a ham from the United Kingdom could deliver a loud signal at such a distance with a mere hundred watts of transmit power, and that they could talk as easily as two people chatting on the telephone. A little later in the conversation (a QSO in ham lingo), the South Carolina ham related how he run a special events ham station from a vintage B17 bomber while in flight! He said it was very noisy, even with headphones.

Listening to the ham bands is just plain fun. You never know what you might encounter. During the same monitoring session, I tuned up the spectrum to the 10 meter band (around 28,400 USB) and heard a ham loud and clear from Santiago, Chile. According to that ham, the climate there is apparently similar to California.

You don’t need a lot of fancy gear or a ham license to listen in on the fun. A shortwave receiver with single-sideband capability will do the trick. If your radio came with an auxiliary wire antenna, deploy it. It will help to boost faint signals. If your radio did not come with an auxiliary wire antenna, it is easy to make one. Get yourself 20 feet of insulated wire (any type will do, but thinner is easier to coil up when not in use), attach an alligator clip (available from most hardware stores) and clip it to the whip antenna on your shortwave portable.

A couple of cautions: do not go nuts with the length of wire. 20 feet is plenty. In addition, do not EVER deploy your antenna where it could fall on a power line or a power line could fall on it. And, finally, if you deploy your wire antenna outdoors, be sure to disconnect it and/or bring it in when foul weather threatens.

For the record, to intercept the ham communications above I listened with headphones on my Satellit 800 receiver, using my horizontal room loop antenna and the BHI Compact In-Line Noise Eliminating Module.

What can you hear? Lots of times, you will hear hams swapping signal reports and telling each other what kind of ham radio transceivers and antennas they are using. During contests, you’ll hear hams making contact after contact, as quickly as they can. But other times you will hear conversations of all types.

Three decades ago, when I was actively DXing as a ham, I once had a conversation with a UK ham who was a falconer. He had flown the birds for the movie Lady Hawke. No kidding. Another time, I worked a station in Christchurch, New Zealand, from Troy, New York, on just 100 watts. If you were a shortwave listener back then, there’s a chance you could have heard those contacts, and it’s a good bet that interesting contacts are taking place today on the ham bands, if you are willing to accept the challenge of tuning around to find them . . . so join the fun!

With the start of a new solar cycle conditions appear to be changing to favor long-range propagation. It seems like the perfect time to start monitoring the ham bands. You never know what you might find.

AWA Presentation: The origin of breadboarding

Many thanks to SWLing Post contributor, Mark (AE2EA), who writes:

Hi Thomas,

FYI, The AWA just posted a presentation by Andy Flowers, K0SM, about amateur radio transmitters from the 1920s & early 30s. Andy is a builder of beautiful early transmitters, among other ham radio pursuits like 10GHz and up microwave work.

Here’s the latest blurb from the AWA:

If you were an amateur radio operator 100 years ago, and wanted a transmitter, you had one choice, you built a breadboard transmitter from scratch, often with components you made yourself. Today, some hams still do this, with designs from the early years of ham radio. AWA member Andy Flowers, K0SM, is one of those modern day vintage transmitter breadboarders.

Join Andy as he explains how early radio amateurs built their own breadboard transmitters with handmade parts, and put them on the air without killing themselves (well, most of the time.)

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!


RNZ and TVNZ to merge (RadioInfo)

New Zealand’s Minister for Broadcasting and Media Kris Faafoi has announced the government’s decision to create a new public media entity by merging RNZ and TVNZ.

According to Faafoi, ensuring New Zealanders continue to have access to reliable, trusted, independent information and local content sits at the heart of the decision.

“The public media sector is extremely important to New Zealanders in providing them with high quality, independent, timely and relevant media content,” Faafoi said.

“But we know the media landscape is changing and the sector is having to adapt to increased competition, changing audience demands and ways of accessing media, falling revenue, and new and emerging digital platforms. We need public media which is responsive to these changes and can flourish.

“RNZ and TVNZ are each trying to adjust to the challenges, but our current public media system, and the legislation it’s based on, is focused on radio and television.

“New Zealanders are among some of the most adaptive audiences when it comes to accessing content in different ways; like their phones rather than television and radio, and from internet-based platforms. We must be sure our public media can adapt to those audience changes, as well as other challenges that media will face in the future.”

“The new public media entity will be built on the best of both RNZ and TVNZ, which will initially become subsidiaries of the new organisation. It will continue to provide what existing audiences value, such as RNZ Concert, as well as better reaching those groups who aren’t currently well served; such as our various ethnic communities and cultures,” Faafoi said[…]

Technologies old and new keep Ukrainians in touch with the world (The Economist)

Battery radios and satellite internet both have jobs to do

In communist Eastern Europe a shortwave radio was a vital piece of equipment for anyone wanting to stay ahead of the censors. Stations such as the bbc World Service, Radio Free Europe and Voice of America broadcast news, entertainment and rock-and-roll across the Iron Curtain.

After the cold war ended, shortwave radios gave way to television and the internet, and the broadcasts were wound down. But on March 3rd, in the aftermath of Russia’s invasion of Ukraine, the bbc announced their return. The World Service has begun nightly news broadcasts into Ukraine and parts of Russia (see map).

Sony ICF-2001 and ICF-2010: Choice radios for spies

Many thanks to SWLing Post contributor, Zack Schindler, who writes:

I have been watching a series on the Science Channel called Spycraft. It is about the “business” and history of modern spycraft and is quite interesting.

The most recent episode (3/8/2022) was called “the Perfect Recruit” and was about spies inside US agencies. One case was about Ana Belén Montes who worked for the DIA and was spying for Cuba. In the story they showed that she used a Sony 2010. Per the article below she was listening to a Cuban Numbers Station on 7887 kHz. A number of other cases are mentioned in there too that involved a Sony 2001 or 2010.

Thank You
Zack Schindler

Thanks for sharing this, Zack! I do believe I remember the Sony being mentioned back when Ana Montes was arrested. Fascinating stuff!

These days, I bet spies would turn to the super compact and durable Belka series receivers
