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!

Many thanks to SWLing Post contributors Adrian Korol, Richard Cuff, and Dennis Dura for the following tips:


Radio Nacional Arcangel San Gabriel picked up around the world (Radio Nacional)

Radio Nacional Arcangel San Gabriel broadcasts on the short wave on Wednesdays from 21 to 23 UTC and on Saturdays from 21 UTC until 03:00 on Sunday on frequency 15476 Khz (USB).

Due to improvements in the audio chain and transmission line and good propagation, we are receiving messages from listeners who had not been able to listen to it for decades and also reception reports from countries such as India, Iceland, Japan, United States, Spain, Italy, United Kingdom, Mexico, Chile, Brazil, Uruguay and all the National territory.

During the summer we broadcast a program called “Uniendo Voces”, a production of the Joint Antarctic Command, the University of Quilmes and RAE, with the presentation of Juan Carlos Benavente.

We also share with you videos and posts in which listeners from around the world share their reception of LRA36. [Continue reading…]

Morse Code Clock For Training Hams (Hackaday)

It might seem antiquated, but Morse code still has a number of advantages compared to other modes of communication, especially over radio waves. It’s low bandwidth compared to voice or even text, and can be discerned against background noise even at extremely low signal strengths. Not every regulatory agency requires amateur operators to learn Morse any more, but for those that do it can be a challenge, so [Cristiano Monteiro] built this clock to help get some practice.

The project is based around his favorite microcontroller, the PIC16F1827, and uses a DS1307 to keep track of time. A single RGB LED at the top of the project enclosure flashes the codes for hours in blue and minutes in red at the beginning of every minute, and in between flashes green for each second.

The Changing Face of Tabletop Radios (Radio World)

While some still offer OTA reception, the specialty segment is dominated by online connectivity

There was a time, of course, when radios were fixtures in people’s homes. But according to Edison Research’s “Infinite Dial 2022” report, the percentage of U.S. homes with “zero” radios inside went from 4% in 2008 to 39% in 2022.

Among the radios that remain, clock and emergency radios have the best chances of justifying their presence to internet-centric consumers. But good ol’ fashioned tabletop radios? AM/FM receivers housed in eye-appealing laminated wood cases with big speakers and hefty knobs?

Mass-market companies such as Panasonic and Sony have abandoned such products. But specialty/quality brands such as C. Crane, Grace Digital, Sangean and Tivoli Audio have not.

These brands bring fresh approaches to the tabletop radio segment through innovation and the harnessing of streaming technology. Still, it’s an uphill battle in a world obsessed with all things internet.

There are several reasons conventional AM/FM tabletop radios have been disappearing from homes.

The first and most obvious is that even by the beginning of this century, radio had long ceased being a destination medium around which the family gathered to listen. In recent decades, the more common uses were morning wakeups, rush-hour commutes, sports on the go and weather emergencies, all well-served by portable radios, though there was still some degree of at-home listening.  [Continue reading…]

Who Benefits By Removing AM From Cars? (Radio World)

Three perspectives on this hot potato threat

Car manufacturers claim they cannot suppress noise getting into the AM signals in their electric vehicles. This article presents the viewpoint of three people who beg to disagree.

Tom King, the chairman of Kintronic Labs Inc., is an expert on AM transmission and noise interference. His company manufactures most of the phasing cabinets for directional arrays on AM stations around the world. Continue reading

Chuck Rippel “Sweetens the deal” on The Great Medium Wave Daylight DX Challenge!

by Jock Elliott, KB2GOM

After yesterday’s post appeared, Chuck Rippel reached out to me and offered:

To whomever logs the most stations using a GE SR-I or SR-II, I will donate that person, a >free< SR-I or SR-II restoration.  Includes, parts, alignment, cleaning, etc….   The winner’s only cost will be shipping.  Should the winner already have a radio I restored, I have an alternate “reward” in mind.

That is a very generous offer, Chuck, and I am sure someone will be the delighted recipient.

In the meantime, there is a very slight modification to the procedure for the challenge: I will be posting a reminder about The Great Medium Wave Daylight DX Challenge on Friday, and then on Saturday, I will post another The Great Medium Wave Daylight DX Challenge blog. That Saturday blog will be the place to post your results in The Challenge . . . .in the Comments section.

“Tea With the Queen”

I asked the AI image-generator DALL-E 2 to create a an image based on this song title.

For those of you who attended David Goren’s Shortwave Shindig at the virtual Winter SWL Fest were treated to a song called Tea With The Queen. This was no ordinary song–as David notes:

This is what happened when I asked ChatGPT to write a country song about a trucker who has tea with Queen Elizabeth whilst they listen to BBC on shortwave radio. Then I got Chris Johnson, an extremely talented and savvy musician, to set it to music.

You can listen to “Tea With The Queen” via the embedded player below, or directly on David Goren’s Soundcloud Page.

Note that David has many more audio goodies on his website Shortwaveology.net.

Thanks for sharing this, David. I think it’s absolutely brilliant!

The Great Medium Wave Daylight DX Challenge

By Jock Elliott, KB2GOM

First a word of acknowledgement and thanks: it was Chuck Rippel who said (in part) — in response to this post — “We could make this interesting by restricting listening to the period 10AM – 2PM maybe 3PM.” And that got me to thinking that maybe a daylight DXing challenge might be fun.

It was Bill Hemphill, who said, responding to the same blog post:

Every year the New Jersey Antique Radio Club has a BCB DX contest for its club members. The main purpose is to encourage the members to put into operation some of the many old am radios that they own. This year’s contest was just completed this past Sunday. For any 24 hour period, using the same radio, you attempt to log the most distant stations. The contest score is the total mileage of the ten stations that are most distant.”

Reading that, I rather liked the idea of using mileage as one way to keep score.

Combining the two ideas, the result is The Great Medium Wave Daylight DX Challenge.

Here are the rules:

  1. Frequency rang is the medium wave band: 520-1710 kHz
  2. 10 am to 2 pm your local time on the Saturday after the post appears (Saturday, March 11, 2023).
  3. Any radio with any antenna, but must be the radio at your location (no using remote internet radios)
  4. The listener must hear the signal in real time
  5. The stations must be ID’ed by listening to the signal.
  6. Your report should include:
    • Your name (or Internet handle)
    • Your receiver and antenna (stay with the same setup from beginning to end; if you use multiple setups, provide a separate report for each).
    • Your location
    • The time, the frequency, and the ID of each station heard
    • The total mileage of your top five most distant stations.

A final point: this is not a contest; it is a challenge. The reward for every participant will be fun and fellowship.

UPDATE: Chuck Rippel did sweeten the pot, though! Check out his generous offer here.

Guest Post: Listening to LRA 36

Many thanks to SWLing Post contributor, TomL, who shares the following guest post:


Listening to LRA 36

by TomL

I finally had time to go outdoors to listen to LRA 36, Antarctica.  People were gushing about how well it is being received.  My location was a park across the street from the Forest Preserve I usually go to (the Forest Preserves are shutdown and gates locked after sundown).  Even though it was after sunset, this Park has no gate or chain to prevent people from parking there.  In the dark, I setup the trusty amplified Loop-on-Ground antenna, SDR, and laptop.  Solar Flux Index about 179, K index 2.

Started recording and, NOTHING! ARRGH.  But I had just heard it at home in the noise!?!?  Waited about two minutes and all of a sudden music started playing in the middle of a song.  S6 – S7 strength with lots of fading.  Very cool.  20 minutes later, went off the air.  Then 10 minutes later, came back on again in the middle of another song.  They must be tweaking the transmitter.  This feels like the 10 kW transmitter; no way could a 1.5 kW be this loud over 12000 kilometers!  Also, an advantage with IQ recording of a spectrum is I could tune into it later.  Good thing because between their tweaking the transmitter, my SDR, and the crazy propagation, I had to tune to 15475.983 kHz in order to get the USB signal perfectly in pitch.

For your listening enjoyment if you have not had a chance to hear it clearly, I have uploaded both recordings to archive.org where you can listen as long as you want.  Worth listening to, playing music of Argentina music bands.  Happy Listening!  Here is the link to Archive.org and the audio files are also embedded below:
