Many thanks to SWLing Post contributor and noted political cartoonist, Carlos Latuff, who shares his radio log art of recent broadcasts from the Voice of Korea, NHK, and KBS.
Voice of Korea
Carlos notes:
Part of Voice of Korea news bulletin about floods in the DPRK:
“…Shortly ago, floods and heavy rains seriously and consecutively damaged some areas of the country, including North Phyongan and Jagang provinces. In this regard, the 22nd emergency enlarged meeting of the Political Bureau of the Eighth Central Committee of the Workers’ Party of Korea was held in an afflicted area in the city of Sinuiju, North Phyongan Province, from July 29 to 30 to take urgent rehabilitation measures.
Prior to the meeting, the respected Comrade Kim Jong Un inspected the flooded areas, together with the premier of the Cabinet and secretaries of the Central Committee of the WPK.
Many public buildings, facilities, roads and railways, including more than 4,100 houses and nearly 3,000 hectares of farmland, were flooded in the city of Sinuiju and Uiju County located on the lower reaches of the Amnok River…”
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.

Hello Thomas,
I hope everything is fine.
To complete Carlos Latuff’s contribution, here is a recording of the French language program of “La Voix de la Corée” made the afternoon of May 30, 2022 at 14h00 UTC on the frequency 13760 kHz with a TECSUN PL-365 connected to a 5m wire antenna of about 5 meters length.
Recording:
I attach the picture of the receiver on an old wall (see above); the screen displays the frequency and the signal characteristics: Signal strength unit: 27 dBu – Signal to Noise Ratio (S/N) unit: 08 dB
The other frequency used at the same time is 15245 kHz but I could not hear anything!
I hope that this information will hold your attention. See you next time. Sincerely yours.

The YouTube channel Phuong DPRK Daily recently posted a video titled Listeners to Radio “Voice of Korea” in Pictures. This video offers a look at photos of VOK Voice of Korea (DPRK) shortwave listeners. I recognize the voice of one of the VOK newscasters as the narrator of this video. It is interesting to take note of the shortwave receivers shown in the photos as well. This video was also posted on the Voice of Korea website on September 25, 2020.
I listen to the English Language Service of VOK Voice of Korea from my suburban listening post in Northern California, USA. The VOK English language broadcasts beamed to South America usually provide the best reception for me. Here is my most recent reception video of VOK. It was recorded on November 10, 2020.
There are more reception videos of VOK available at my website Willow Slough DX. These videos include newscasts read by the male announcer heard on the photo album video.
Happy SWLing! The shortwave broadcast bands are beginning to improve after the long nadir of solar minimum!
Many thanks to SWLing Post contributor, TomL, who shares a recording he made of the Voice of Korea on June 14, 2018. This English broadcast focuses on the Singapore summit and is, no doubt, historic in its content. [Note that we’ve posted other recordings on the Shortwave Radio Audio Archive.]
TomL notes:
Recorded on my noisy Lenovo laptop, SDRPlay RSP2, and an unamplified 18.5 foot antenna on the roof of my SUV.
I’m most impressed with the quality of his recording–VOK is not the easiest station to snag in the US midwest:
