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!

I would give this a SINPO Rating of 66666!

Check out this image taken of the front of the Tecsun PL-880 while listening to this broadcast, showing just how strong the signal is.

I was a bit surprised, never seen something this high before, especially on shortwave!

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”.[…]

North Korea intensifies shortwave jamming

North Korea has been from the beginning of March continually signal jamming radio broadcasts on the shortwave frequency used by the South Korean non-profit broadcaster Unification Media Group (UMG). Given the present situation, in which North Korean residents might be influenced by outside information condemning the regime and explaining the purpose of the sanctions imposed by the United Nations, the regime has showed the will to block sources of outside information that might cause unrest.

The shortwave frequency […] in question, 7515 [kHz], has been actively jammed starting on March 1st making it extremely difficult for North Korean listeners to tune in. On the 15, UMG organization began using three receivers to test out reception at that and adjacent frequencies on a daily basis and was able to confirm that the exact signal is being jammed.

The blocking effort is being concentrated on the time period from 10pm- midnight. Specifically, from 10-11pm the jamming is very strong. The signal jamming is undetectable from midnight to 1am. The signal blocking became weaker at midnight on March 15, from which point onward the entire three hour broadcast was audible. Starting on the 17, UMG moved the frequency, but the jamming operators seemed not to notice because the interference continued on the old wavelength.
