good catch. This is Voice of Korea in Korean , I've also seen it listed as Pyongyang Broadcasting Service. its 50 kw from Kanggye, North Korea. It's non directional so I guess it targets the south or maybe this is what North Koreans hear on their untuneable radios that only recieve one station. I've read about North korean police shutting off power to buildings in Pyongyang & going door to door checking to see if people have contraband video tapes or cd's in their players or have tuned the built in radios illegally.
No, the shortwave stuff is for the South Koreans (which Seoul tries to jam)....there is a large black market in S. Korean DVDs in China; North Koreans sneak across the shambolic Chinese/DPRK border for work/food and they buy the stuff and el cheapo DVD players.
The one-station radios work for AM only. Actually they have FM too, so it must be an issue where the radios are channelized and you only get two AM, one FM, and one SW station.
