International FM DXing: North Korea FM radio jamming in South Korea

In Seoul, and Korea Demilitarized Zone (DMZ), there has some North Korea FM radio can be received there, transmitted from Kaesong and Hanju of North Korea.

Currently South Korea is jamming North Korea FM radio signal in South Korea territories.

- 92.5MHz: KCBS Pyongyang FM Pangsong from Kaesong is jammed by South Korea with beep signal.
- 97.8MHz: KCBS Pyongyang FM Pangsong from Kaesong is jammed by South Korea Jayu FM Bangsong from Cheorwon of Gangwon province FM 97.7MHz
- 103.7MHz: KCBS Pyongyang FM  Chosun Jungang Pangsong from Haeju is jammed by South Korea Military Jammer from Namsan, Seoul
- 102.3MHz KCBS Pyongyang FM  Chosun Jungang Pangsong from Kaesong


North Korea FM 103.7MHz is also jammed by SBS Love FM 103.5MHz from Seoul in Korean DMZ and Seoul metropolitan area, FM 103.5MHz by SBS Love FM is occupied with 10kW power.

In my opinion, South Korea still can jam North Korea signal by adding more FM stations in South Korea. Such as:

- FM 102.1MHz and FM 102.5MHz low power transmitters within Korean DMZ areas
- FM 92.5MHz in Seoul Korea with 10kW power to jam North Korea signal
- FM 103.8MHz low power transmitters within Korean DMZ areas

Jamming North Korea FM signal is not only done by playing beep sound, it can be done by launching commercial relay station, even can increase power of existing transmitter to jam North Korea signal.

==EBS Gyoyuk Bangsong parameter==
Frequency: FM 102.3MHz
Power: 10kW (suggested power)
Transmitting location: Weonhyobong (ccg)

==MBC Munhwa Bangsong==
Frequency: FM 92.3MHz
Power: 10kW
Transmitting location: Chuncheon/Daeryongsan (gan)

With increasing power of existing South Korea radio stations, the North Korea radio stations will face heavy co-channel interference within South Korea areas. So, listeners won't be able to receive North Korea stations there.
