How to find the Pyongyang numbers station (V15) including an off-air recording

Many thanks to SWLing Post contributor, Mark Fahey (our resident North Korea specialist)  who shares the following comment regarding our recent post about the re-activation of the North Korean Numbers station:

The Pyongyang numbers (designated V15) have either become less regular or changed their schedule since March. Its been a few months since I have personally received them – but I also haven’t been specifically tuning in for them lately so maybe I have simply missed noticing a timing change.

If you want to find the North Korean numbers, they are read out in a block between songs within the regular programing of the Pyongyang Pangsong radio station.

The choice of music immediately before the number block seems to indicate which recipient agent the transmission is directed to.

For Agent 27 “We Will Go Together with a Song Of Joy” is played, whereas Agent 21’s song is “Spring of my Hometown.”

The announcements typically take between 5 to 10 minutes to read dependent on the number of digits passed. The transmission schedule is variable; in early 2017 the broadcast alternated with a cycle of one week on Thursday night at 12:45AM Pyongyang Time (1615 UTC) and the following week on Saturday night at 11:45PM Pyongyang Time (1515 UTC).??

Pyongyang Pangsong can be heard on these shortwave band frequencies (it is also on MF & FM on the Korean peninsular):

  • 3250 kHz, Pyongyang 100KW Transmitter
  • 3320 kHz, Pyongyang 50KW Transmitter
  • 6400 kHz, Kanggye 50KW Transmitter

Mark followed up this morning with a off-air recording of V15 on 3250kHz. Mark comments, “I will leave the decrypted message content to your imagination!”

Mark: thank you for taking the time to write up this V15 tutorial and sharing this recording!

Gary DeBock’s Ultralight Radio DXpedition in Hawaii

Many thanks to SWLing Post contributor, Gary DeBock, who shares the following notes and recordings from an Ultralight DXpedition in Kona, Hawaii:

The Kona, Hawaii Ultralight Radio DXpedition was conducted from a sixth floor oceanfront motel room in the Royal Kona Resort Motel from April 9-12 (during an anniversary trip with my wife). A newly designed “airport friendly” 5 inch FSL antenna (designed to fit within hand-carry luggage, inside a plastic tote) and a 7.5 inch loopstick C.Crane Skywave Ultralight were used to track down and record Asian and South Pacific Medium Wave DX from such rare stations as 540-2AP (Apia, Samoa), 621-Tuvalu (Funafuti, Tuvalu) and 1440-Kiribati (Bairiki, Kiribati). Here are three extremely strong recording links for these exotic stations, including the daily sign off routines for 621-Tuvalu and 1440-Kiribati:

540 2AP Apia, Samoa Extremely strong Christian worship music (Samoan style) at 0931 UTC on April 9 (S9+ level)

621 Tuvalu Funafuti, Tuvalu Over 8 minutes of traditional island music at an S9 level, including the sign off routine (with national anthem) at 1000 UTC

1440 Kiribati Bairiki, Kiribati Over 7 minutes of traditional island music, station ID’s in English and the native language, and the national anthem (followed by a blistering 1000 Hz tone) at the 0936 UTC sign off– all at a strong level

David recommends the Sangean H201 AM/FM waterproof shower radio

A few weeks ago, SWLing Post reader, David Lang, asked for a radio recommendation–one to replace the shortwave receiver that once lived on his bathroom countertop. Since he primarily wanted to listen to a local AM broadcaster, I recommended he go a different route with his next rig to save money and extend the radio’s longevity.

I suggested the ($61 US) Sangean H201 which is specifically designed for humid environments. I had considered this receiver as a gift in the past, but had never actually used one myself. I felt like it was a pretty safe bet, though. David purchased the H201 and recently shared his review:

Well, I’m so glad that I was patient and waited for a reply before I bought a radio to replace the old one that I had in my bathroom. I think the Sangean H201 is going to be the perfect replacement. I don’t know if anyone has provided a review for this radio but here are my thoughts at the moment:

The H201 is compact. Not quite as small as my 909 but just the right size to sit on my bathroom countertop and not take up near as much room as the radio it replaced.

Its appearance is clean, simple and intuitive. It’s also waterproof, a feature that is comforting since it will spend most of its life in the humid environment of a bathroom. The display is large and easily read. The display includes battery strength indicator, band, memory preset, weather alert and frequency in the display. The buttons are just the right size and have a distinct but smooth action.

It might have been better for me if the power button had been on the top instead of the bottom right hand face of the cabinet but that is in no way a deal killer.

The H201’s reception is fine for what I need it to do which is receive the primary AM radio stations for our metroplex area (Dallas/Fort Worth) which brings me to my next section of commentary; sound quality. The sound quality of the H201 is exceptional. It’s crystal clear and leans toward the warm side. I’m talking about timbre. My sangean 909 also has great sound but is brighter in timbre. Think about the difference between a French horn and a trumpet. The 909 is a trumpet, the H201 is a French Horn or perhaps a Euphonium. I like the amber display and the half circle carry handle that turns in or out of the cavity in the back of the radio is really convenient.

At times I have to adjust the position of the radio to eliminate a bit of static on AM but I think that’s pretty typical for AM. My comments here are not near as technical as some reviews I’ve read on other radios, particularly short wave models.

While I use and appreciate many of those types of features on my other radios, for my purposes I’m not sure the ‘technical’ is necessary to promote the positive aspects of this radio.

Bottom line: I like it because it fits perfectly for the purpose I needed. Even in a non-humid room, this little rig is a great, simple portable radio for AM/FM local station listening. Thanks so much for the suggestion!!

Cheers!
David Lang

Thank you for taking the time to share your thoughts, David! I’ve been very pleased with Sangean radios that employ this particular chassis style (like the Sangean PR-D5BK Sangean PR-D9WSangean PR-D7, and even the Sangean WFR-28). These models tend to have a durable feel, robust hard plastic body and the audio is pleasant from the built-in speaker(s).

The Sangean H201 can be purchased from a number of retailers including Amazon, NewEgg, WalMart and, of course, eBay.

Thanks again, David!

North Korea activates numbers station?

Many thanks to a number of SWLing Post contributors who’ve shared this particular item from The National Interest:

North Korea Broadcasts Really Strange Messages As New Nuclear Weapons Test Looms

Pyongyang is reportedly broadcasting encrypted messages reminiscent of those used to contact spies during the Cold War.

[…]As North Korea prepares to mark a key anniversary — the birthday of North Korean founder Kim Il-sung — a U.S. Navy carrier strike group led by the USS Carl Vinson is on its way to Korea.

[…]Radio Pyongyang began broadcasting peculiar messages at 1:15 a.m. (local time). The messages included numbers and pages, such as No. 69 on page 823, No. 92 on page 467, and No. 100 on page 957.“I’m giving review works in elementary information technology lessons of the remote education university for No. 27 expedition agents,” the broadcaster explained before repeating her message.

The messages are broadcast over shortwave radio.

Yonhap News Agency reports the numbers are different from past announcements. Since June of last year, Pyongyang has broadcast its messages 32 times.

Update: Since I haven’t gotten any direct listener reports regarding this numbers station’s reactivation, I’ve added a question mark in the title. Please comment if you’ve logged this station (and we’d all love a recording!).

One vintage radio in two classic films

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

This evening I watched the excellent Undercover: How to Operate Behind Enemy Lines on Netflix streaming. This is a 1943 training film for Office of Strategic Services personnel learning how be secret agents. The film was directed by the legendary John Ford who also took an acting role in the film. In this scene, Al is receiving his forged papers from an OSS agent before leaving for Germany. A radio may seen on a shelf in the background.

Undercover: How to Operate Behind Enemy Lines is also available on YouTube:

Click here to view on YouTube.

The next film is much better known. The same model radio makes a foreground appearance in Some Like it Hot. Osgood Fielding III has one of these on his yacht.

Maybe Osgood is laughing because the film takes place in 1929 and the company that made the radio was founded several years later.

I won’t spoil the secret of this radio’s maker and model. It will probably not take long for SWLing Post readers to come up with an answer.

Post readers: are you up for the challenge? 🙂 What model of radio do we see here? I’ll keep quiet, because it’s one of my favorite manufacturers.

And, Dan, many thanks. I really do owe you one because I was not familiar with Undercover: How to Operate Behind Enemy Lines. I can’t believe there was a WWII era Ford film I had missed. I, too, have Netflix but the YouTube copy you suggested is actually a better restored version in terms of audio.  Thanks again!

RNW: Video of Flevoland Shortwave station

Many thanks to SWLing Post contributor, Peter Veenendaal, who shares the following video and notes:

I am a former employee of Radio Netherlands Worldwide, which stopped broadcasting exactly 5 years ago next May.

Three years ago I made this short video of the Flevoland Shortwave station RNW used until 2007. It’s still there, idle and hoping for better times.

Many thanks, Peter–most impressive! The magnitude of those curtain antennas is simply amazing. Thank you for sharing.
