Abductees’ relatives record radio messages for broadcast to North Korea (NHK)

Family members of Japanese nationals abducted by North Korea have recorded encouraging messages for a radio broadcast aimed at the country.

The messages were recorded in Tokyo for Free North Korea Radio, a shortwave broadcaster. Its daily radio program is run by a group of people who defected from the North to South Korea.

The abductees’ relatives called on their loved ones never to give up until they are rescued.

The leader of the relatives’ group, Yokota Takuya, is a younger brother of Yokota Megumi, who was abducted in 1977 at the age of 13. He asked his sister how she is doing. He also said he is sorry that she has had to spend a long time in North Korea without freedom.

He added that the relatives will never give up until they achieve the return of all the abductees.

His twin brother, Yokota Tetsuya, told his sister about their parents. He said that their father, who died three years ago, thought about rescuing his daughter every day.

He added that their 87-year-old mother often falls over, but is doing well. He vowed to get back his sister and asked her to stay healthy until she can be reunited with her mother.

Japanese Prime Minister Kishida Fumio said last month that he wants to start high-level talks under his direct control to hold a summit with North Korea at an early date.

Yokota Takuya said after the recording that he wants the Japanese government to continue its steady diplomatic efforts until all the abductees are returned.

He expressed hope that a Japan-North Korea summit can be held and that North Korean leader Kim Jong Un will decide to hand over all the abductees. [Read the full story and watch the video here…]

New Book: Exploring Space Weather with DIY Magnetometers (Amazon)

Many thanks to SWLing Post contributor, Sten Odenwald, who writes:

Hi Thomas!

Thanks so much for your contribution to the History of Space Weather book I published several years ago!

I have just published a new book I think you might be interested in. It’s called Exploring Space Weather with DIY Magnetometers, and it’s now available at amazon.com (see below). It provides step-by-step designs for building six sensitive instruments for under $60.00 that can measure real-time changes in Earth’s magnetic field.

If you are interested in such a building project, or you know of a family member, teacher, or even a student looking for a science fair project, this book will show you how to build these instruments. I also provide examples of storm events that were actually detected by each design so you can see what typical data looks like. For additional examples and updates, visit my blog page at http://sten.astronomycafe.net/diy-magnetometers/

Thanks again for your help!

WMLK on the air (Paul Walker)

Many thanks to SWLing Post contributor, Paul Walker, who shares the following tip:

It appears they are now operating at US night times now. For the longest time, as you may be aware, they were only on 9275 kHz during the day.

Sometime around mid last week, they were being reported on 15150 kHz as well.

And I finally logged them too.. nice signal on 15150 kHz here just after 0400!!

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 Kim Elliott and Dennis Dura for the following tips:

Opinion: My father may be gone, but ‘our’ radio is still going (LA Times)

My most prized possession was once somebody’s trash.

It’s a blocky, black radio that was manufactured in 1941, the year my father was 12 years old. I snatched it from the county landfill when I was 13, in 1978.

The person who threw it away must have determined they couldn’t fix it, though it seemed they thought someone else might. They had set the radio off to the side of the dumpster, safe in plain view, just in case some industrious person with know-how appeared.

That person was my father, who ran an electronics repair business from our garage. Though at first reluctant to save “that ugly old thing,” he seemed pleased hours later when he entered the kitchen announcing that the radio worked fine and had only needed a tube. For years after this, my father kept that radio on a shelf above his workbench, listening to country singers croon about lonesome truckers.

I like to think of myself as a minimalist, but since my father died in 1994, I’ve carried what I consider to be “our” radio thousands of miles from the Appalachian farm where I grew up, out to Los Angeles, and then many years later back home again. In California, I’d tune our radio to horse races being transmitted from Santa Anita or Hollywood Park while cleaning my kitchen. Or I listened to Paul Harvey, Casey Kasem or evangelists spouting “truths” about Jesus and cars. [Continue reading…]

AM Listenership by State, DMA (Radio World)

New analysis of AM reach provides market-level insight to listening habits

Following up its recent report on the 141 local markets where at least 20% of the market listens to AM radio, Nielsen has released a deeper look with new data at the state- and DMA-level.

Pierre Bouvard, chief insights officer of the Cumulus Media / Westwood One Audio Active Group, recently posted an analysis of the findings. The data comes from the Fall 2022 survey, but is based on all U.S. radio stations, not just Nielsen subscribers.

Nationwide, 30.9% of radio reach comes from AM stations, representing 82,346,8000 American radio listeners aged 12+ who listen to AM every month. At the state level it ranged from a high of 52.7% in North Dakota to a low of 4.6% in the District of Columbia. In 29 states, the percent of radio reach via AM is greater than 20%.

Not All Those AM Listeners Are in Cars, Bozzella Argues (Radio World)

Auto group also says it would take two decades for fleet to turn over and AM to phase out

“Whether or not AM radio is physically installed in vehicles in the future has no bearing on the multiple methods of delivering those emergency communications alerts to the public.”

So writes the president and CEO of the Alliance for Automotive Innovation. John Bozzella used a blog post this past week to summarize the auto industry’s case against a mandate to include AM radio in cars.

It’s simply not necessary, he wrote; and government shouldn’t be propping up a particular technology that’s competing with other communications options, either.

“It’s tempting to take a cheap shot at misplaced government priorities and unnecessary mandates or make light of the whole thing with a jab about laws for hand-crank windows or cassette players,” he writes, calling the legislation a bipartisan solution searching for a problem. [Continue reading…]

A Hallicrafters SX-28/A in “Battle of the Bulge”

3 Replies

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

Not a false alarm this time — one of the most striking appearances of a classic shortwave receiver was in Battle of the Bulge, the 1960’s movie about the great battle between German and U.S. forces during World War II, lasting five weeks between the end of 1944 and beginning of 1945. This movie had some of the biggest stars of the time, including Henry Fonda, Robert Ryan, Telly Savalas, and Charles Bronson. Robert Shaw played the German commander of the offensive in the Ardennes and scenes in his command trailer showed a beautiful Hallicrafters SX-28/A which audiences are led to believe was both a transmitter and a receiver.

In this scene, the radio is shown as Shaw is chewed out by his superior in the trailer for not making more progress on the battlefield.

The SX-28 is one of the most amazing radios Hallicrafters made. Thanks for sharing this, Dan!

Many thanks to SWLing Post contributor, Dan Robinson, who asks if anyone can identify the receiver in the screenshot below from the final season of The Marvelous Mrs. Maizel (click image to enlarge):

The image isn’t super clear because there isn’t a close-up of this radio in the episode.

If you recognize this model, please comment!

Mark spots radios in the original “Hawaii Five Oh”

5 Replies

Many thanks to SWLing Post contributor, Mark Hirst, who writes:

Thomas,

I recently picked up a couple of DVD boxsets of Hawaii Five Oh from my local charity shop.

These old shows are always an interesting watch, giving insights into fashions, cars, cultural norms and story lines from the time.

I spotted these radios, sometimes used for exposition or just props in various episodes.

Mark

Thank you for sharing, Mark! I bet readers can recognize all of these fine vintage radios! The top photo might be the trickiest in terms of narrowing down the exact model.

I haven’t watched Hawaii Five Oh in decades. It would be fun to rewatch a few episodes–I loved that show in my youth!

Grayhat discovers the RME-6900

Many thanks to SWLing Post contributor, Grayhat, who shares the following:

The RME-6900: A Nice Boat Anchor from the sixties

Photo Source: wa3dsp.org

Let me start by thanking my dear friend Kostas (SV3ORA) since he was the one who sent me a link to the rig asking me if I liked it, and you bet, as soon as I saw the image I loved that rig; the receiver I’m talking about is the RME-6900 and the link Kostas sent me is the following one: https://wa3dsp.org/RME/RME6900/

Now, just look at that front panel, the design is a classic and somewhat resembles the Hammarlund and Collins ones from the same period, reading the information via the above link, and some others found on the internet:

The receiver doesn’t seem to be “top notch” yet, it’s a good one, and I really love the look and the “drum dial” at the top, also, the RME has an interesting history; it was founded by two hams and later on, after a merge with Electrovoice, it gave birth to the TEN-TEC company. RME apparently was only active for a relatively short timeframe and built rigs in pretty low quantity

https://rigreference.com/manufacturers/rme

Bottom line, do you have any further information about this receiver (or even own one)–?

I’m also curious to know if I’m alone or if someone else here likes its look as much as I do.

Mark’s collection of vintage micro radios

Many thanks to SWLing Post contributor, Mark Pascoe, who writes:

Hi, Thomas.

I rarely see photos of micro radio collections, so I thought some of your subscribers may be interested in seeing my little collection.

These are all late 50s to 60s radios made in Japan and hand soldered. Just over 50% of them are still working ( Deoxit is my best friend) l live in Adelaide Australia and recently retired doing the customary downsizing thing. Now I live in a small townhouse and have what must be one of the smallest radio shacks, 1m x 1/2 metre!

With a 50 ft long wire running front to back above my roof. I’m not an overly experienced SWL, and I have a question. I have 3 SW radio’s with 5 antenna attachment points. Is there a recommended antenna splitter that goes 1 into 5 without any interference ? I currently manually connect/disconnect my antenna’s.

Thanks Mark Pascoe.

These are simply amazing, Mark! I don’t believe anyone has ever shared photos of their micro radio collection before, so we’re most appreciative. There are some amazing designs in this collection!
