N. Korea halts radio station known for sending coded messages to spies in Seoul (The Korea Herald)

North Korea is pressing ahead with measures to disband its inter-Korean organizations, apparently stopping a radio station previously used to send encrypted messages to its spies in South Korea.

As of Saturday, the North appears to have stopped broadcasting the state-run Pyongyang Radio and cut off access to its website.

The latest move comes after North Korean leader Kim Jong-un ordered “readjusting and reforming” its organizations in charge of inter-Korean affairs during a key Workers’ Party meeting last month amid growing cross-border tensions.

Pyongyang Radio is known for broadcasting a series of mysterious numbers, presumed to be coded messages, giving directions to its agents operating in South Korea.

The North resumed such broadcasts in 2016 after suspending them in 2000, when the two Koreas held their first historic summit. [Continue reading…]

Shiokaze Shortwave Radio Service Faces Crisis

Shortwave Radio for Japanese Abductees Faces Crisis

Tokyo, Dec. 31 (Jiji Press)—The Shiokaze shortwave radio service for Japanese nationals abducted to North Korea faces a crisis because it will be unable to counter jamming by Pyongyang during facility renewal work in fiscal 2024.

The situation “contradicts the government’s policy of giving top priority to the abduction issue,” said the group playing the leading role in the radio broadcasts.

Shiokaze, which means sea breeze, began broadcasting in 2005, operated mainly by the Investigation Commission on Missing Japanese Probably Related to North Korea. It conveys messages from family members of abductees and news from Japan and abroad.

The radio is constantly hit by jamming signals from North Korea. Since 2019, Shiokaze has been conducting double broadcasting using two frequencies as a countermeasure.

Shiokaze’s transmission base is within KDDI Corp.’s Yamata transmitting station in Koga, Ibaraki Prefecture, eastern Japan.

The number of transmitters at the station will be reduced by two from the current seven partly due to the aging facility. There will be a period when double broadcasting is not possible during the work.

Japanese public broadcaster NHK, which uses the KDDI station as a base for its overseas radio services, said that work related to the transmitters will last up to 10 months from the second half of fiscal 2024.

“For a while during the work, Shiokaze is expected to broadcast on one frequency,” said an official of NHK, formally called Japan Broadcasting Corp.

“We recognize that the work is necessary in order to continue the two frequency system although (Shiokaze) will be a single frequency service temporarily,” then Chief Cabinet Secretary Hirokazu Matsuno told a meeting of a parliamentary special panel on the abduction issue Dec. 4, 2023.

Meanwhile, a Cabinet Secretariat official expressed concern, saying that “the risk of obstruction will increase more than ever,” albeit temporarily. [Continue reading…]

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!!

Mark explores North Korean DRM broadcasts over shortwave

7 Replies

In the last issue of Radio Waves, we featured an article by Hans Johnson at Red Tech about DRM broadcasts originating in North Korea. This caused me to question exactly what these DRM broadcasts were (Voice of Korea?) and why they’ve chosen to use DRM as the mode.

Of course, who really knows? North Korea isn’t public about any of their activities, so we rely on information from enthusiasts who have taken it upon themselves to investigate and confirm. Johnson assumed, “The most likely use [of DRM] would be as an audio feed to other stations and sites.” He used Radio New Zealand’s DRM service as an example, but I felt this to be unlikely with North Korea who doesn’t seem to use FM, MW, or shortwave relay sites in other parts of the world.

Fortunately, our friend Mark Fahey is an expert on North Korean media, broadcasts, and propaganda. Mark is the author and curator of the dynamic Behind The Curtain project.

I reached out to Mark via text message regarding North Korea’s use of DRM. Here’s what Mark shared with me earlier this week. This roughly follows the string of messages we exchanged.

Mark writes:

[October 3, 2022] I have been turning into the North Korean DRM today on the new reported frequency in the [Red Tech] magazine: 6140kHz, though it’s not VOK, it’s a relay of 819kHz Pyongyang.

This service is called KCBS – Korean Central Broadcasting Service – it’s the main domestic service that is available on MW (a few FM outlets) and domestic SW across North Korea.

I will grab an audio ID off DRM for you at the top of the next hour – 0100 UTC. The DRM broadcast is only running one audio stream. It’s ACC audio 14.56kbps. As for purpose, maybe to feed the national AM relays, but also could be for North Korean ships, etc.

The other DRM frequency of 3205kHz is not on the air at the moment. I will check for it over the next 24hrs etc.

I just recorded the top of the hour. It was going in and out of DRM sync – I will send it now. I will grab a better sample tonight when there is a darkness path. The sun is well up in Pyongyang & Sydney at the moment (Noon Sydney – 10AM North Korea). Here is the Top Of The Hour ID from 10 minutes ago…

KCBS 6140 kHz (October 3, 2022)

I will record the station opening as well tomorrow morning – this domestic service also has an interval signal (the same tune as VOK–the first bars of “The Song (Hymn) of Kim Il Sung”). The opening is at 2000 UTC.

[October 4, 2022] OK here you go: both audio files (one from 6140kHz and the other from 3205kHz) are just from minutes ago as KCBS Pyongyang signed on. The signals go in and out of DRM lock here and this morning 3205kHz was the better–displayed at SNR at 13dB but still the DRM signal was breaking up.

Both DRM transmitters are running the same program: the main MW national service as heard on 819kHz in Pyongyang.

So I’m sure this DRM has nothing to do with the Voice Of Korea and is for domestic purposes.

I actually do not think it has anything to do with feeding remote transmitters as the DPRK has fibre and microwave links already in place for that purpose. I myself think it’s more likely intended for North Korean fishing vessels, navy, merchant shipping etc. But of course, nobody truly knows!

KCBS 3205 kHz (October 4, 2022)

KCBS 6140 kHz (October 4, 2022)

Thank you so much for your recordings and insight, Mark!

As I mentioned, Mark has a massive DPRK audio repository on his website Behind The Curtain. These are recordings you simply can’t find anywhere else, including hours of pristine Pyongyang FM recorded on a CC-Crane Witness Mark personally smuggled into Pyongyang.

In fact, the above photo is the CC Witness in Mark’s hand overlooking central Pyongyang.

Mark told me that the CC Witness was ideal–he used it on a number of content gathering trips to North Korea as it resembled an MP3 player or dictation recorder rather than a radio. Since it wasn’t suspected as being a radio recording device, it passed through the North Korean border each time without incident.

It’s an understatement to say that Mark took a number of risks to gather North Korean media from “Behind the Curtain.” Thank you, again, Mark, for sharing this info about DPRK DRM broadcasts.
