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!


Inmate-produced radio station streams beyond prison walls (NBC News)

Inside Wire, available 24/7 to incarcerated people in Colorado and to online listeners around the world, is said to offer a chance for prisoners and those they harmed to heal.

LIMON, Colo. — Herbert Alexander stares at the sound waves jumping on the computer screen in front of him, his shaved head partially covered by headphones. He’s editing a short audio feature on incarcerated fathers, a subject with which he is intimately familiar.

His two sons will soon hear his voice and his story because Alexander, 46, an inmate at Limon Correctional Facility, is preparing a segment for Inside Wire: Colorado Prison Radio, billed as the first radio station to be produced inside a prison and available to the world outside.

Other radio stations created in prisons generally air only within the walls of their lockups, but Inside Wire, which premiered March 1, reaches all 21 prisons in the state and beyond, online and by app, making the first of its kind in the country, organizers said.

“In spaces where isolation continues, this medium can cut through that,” said Ryan Conarro, general manager and program director of Inside Wire and creative producer for the University of Denver Prison Arts Initiative, which oversees the program in partnership with the Colorado Department of Corrections.

A case for the Belka-DX and cautionary tale!

Many thanks to SWLing Post contributor, Steve Allen (KZ4TN), who shares the following guest post:


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.)

Watch it here:

Czech Radio sends broadcasting gear to Ukraine

Many thanks to SWLing Post contributor, Chris Greenway, for sharing this story via Twitter:

Czech Radio helping Ukrainian public broadcaster’

At the request of the Ukrainian public broadcaster UA: PBC, Czech Radio is sending technical equipment essential for broadcasting to Ukraine. Thanks to this donation it will be possible to set up temporary Ukrainian radio stations in the event that the current broadcasting facilities are occupied or destroyed by Russian troops. Czech Radio has also launched an internet stream of the UA:PBC radio broadcast in Ukrainian. The stream will be available on the audio portal and in the mobile application mujRozhlas.cz. The aim of the project is to make information about the war in Ukraine available daily to refugees and Ukrainians in the Czech Republic.
