Chris’ Seoul AM Radio Listening Guide now live

Many thanks to SWLing Post contributor, Chris Kadlec, who shares the following announcement about his Seoul AM Radio Listening Guide:

After a long 14 months of work, I’m happy to present the completed Seoul AM Radio Listening Guide, a three-hour documentary broadcast exploring the Seoul AM band one frequency at a time, plus a look at the radio war on the Korean peninsula accompanied by a 115-page guide.

In addition to radio broadcasts from across East Asia, the broadcast includes Korean noise jammers and AM, FM, shortwave, and television propaganda broadcasts from both the north and the south, additionally outlined in a 25-page broadcast transcript and 115-page informational guide. It also includes:

* A comprehensive list of 260 East Asian AM stations, including station names, tower locations, distance and direction from Seoul, parallel FM frequencies, broadcast hours, and station website links.

* A full bandscan of 235 regular nightly skywave signals as heard after the sun sets over Seoul.

* Daytime groundwave bandscans taken from eleven different locations in the Seoul metro area, along the North Korean border, beside the sea, and in Korea’s mountainous interior with background information about each location.

* A guide showing stations organized by their network affiliations in addition to privately-owned stations and networks. Alternatively, stations are also shown organized by country, region, and city.

* A chart showing signal strength for each bandscan – day and night – in bar graph format.

* A full colour-coded regional station map covering both skywave and groundwave signals.

* A view of some of Korea’s signal jammers as seen on an SDR (software-defined radio).

* Plus, a complete transcript of the three-hour audio broadcast with additional information on the featured audio clips as well as the songs featured in those clips.

Brilliant, Chris! I can only imagine the amount of time and effort you’ve put into this guide. Thank you!

Korean jammers and propaganda stations

Many thanks to SWLing Post contributor, Chris Kadlec, who has kindly (and upon my request) shared this interesting audio survey of Korean jammers and propaganda stations.

This is the final 45 minutes of my 3-hour – exactly 3 hours – broadcast of East Asia AM radio (skywave as heard from Seoul, frequency by frequency).

Click here to download or play in a new window.

This includes jammers and propaganda stations on TV, FM, AM, and SW, though the AM band is covered in the first 2 hours. Some stations covered include Voice of the People, Echo of Hope, Jayuui Sori, Jayu FM, and Korean Central Television, as well as a look at the sounds of more than 30 Korean jammers one frequency at a time.

At the end of this month, the first 2 hrs. 15 min. will be released with a 60+ page guide, broadcast transcript with all song titles from the broadcast, and station map and all audio will be posted in a (somewhat) visible location. This project has taken 14 months to complete, so I truly hope you’ll take the time to become educated on the radio wars on the Korean peninsula. And if you’re too busy now, this part will be included in the full broadcast coming soon, so do not fret!

This is fascinating, Chris.  Thank you for taking the time to share this with us–I imagine you’ve put in a number of days recording, editing, and narrating this fine spectrum survey. I’m also certain our community member, Mark Fahey, will love this (if he hasn’t already discovered your work)!

Please keep us updated on your project!

Numbers Stations and the two Koreas

A little after midnight, early on the morning of July 15, as most of the Korean peninsula slept, were North Korean spies up late listening to the radio?

This was the big question after a strange sequence of numbers was read out on a North Korean radio station. It sounded a lot like the coded messages previously used to relay instructions to spies during the Cold War and perhaps that was the point.

The broadcast began at 12:45am, according to the Joong Ang Ilbo.

“From now on, I will give review work for the subject of mathematics under the curriculum of a remote education university for exploration agents of the 27th bureau.”

It continued, “On page 459, question number 35, on page 913, question number 55, on page 135, question number 86, on page 257, question number 2,” and so on. It lasted for 14 minutes.[…]

North Korean numbers station in the press

SWLingPost-Spy-Numbers-Station

I’ve been offline and off-grid this week and have accumulated quite the backlog of email.

One news item that caught the attention of a large number of readers (thanks to all for the tips–!) was North Korean spy numbers. I’m very curious if any readers have logged and recorded this station–if so, please comment and consider sharing your recording!

The news was featured on at least two prominent news sites:

North Korea’s radio broadcast of string of mysterious numbers is possible code

Numbers read on state radio may be cold war-era method of sending coded messages to spies in South Korea – or an attempt to wage psychological warfare

North Korea’s state radio has recently broadcast strings of indecipherable numbers, according to officials in Seoul, in a possible resumption of a cold war-era method of sending coded messages to spies operating in South Korea.

A female announcer at the radio station read numbers for two minutes on 24 June and 14 minutes on Friday, according to Seoul’s unification ministry and national intelligence service (NIS). A copy of those comments provided by the ministry included phrases such as “No 35 on Page 459” and “No 55 on Page 913”.[…]

North Korea is criticised by South Korea for ‘spy broadcasts’

South Korean officials have criticised North Korea after it apparently resurrected a Cold War-era method of contacting spies.

In recent weeks, mysterious strings of numbers have twice been broadcast over the radio from the North.

A spokesman for the South’s Unification Ministry said it couldn’t be sure about North Korea’s “hidden intentions”.

But it urged the North to “desist from such outdated practices”.[…]
