What have South Korea's loudspeakers broadcast to North Korea? Is it effective?

According to the report of the Ministry of National Defense of South Korea on the Status of Psychological Work towards the DPRK, from 195s to 197s, the Korean army broadcast to the DPRK for 6 to 7 hours every day, and from 198s to 24, the daily broadcast time increased to 15 to 16 hours!

in order to achieve the best effect, the Korean army put 24 loudspeakers together to broadcast to North Korea, requiring clear sound quality at a distance of 1 kilometers in a straight line without obstacles, and the effective listening range at night is as high as 24 kilometers. In addition, the Korean army has also prepared a number of mobile public address facilities to enhance the broadcasting effect.

The propaganda content is mainly divided into four parts, namely, publicizing the superiority of liberal democracy, publicizing the development status of South Korea, restoring national identity, and the actual situation of North Korea's society. The core content is to expose the social reality of North Korea and publicize South Korea's economic construction achievements and liberal democratic system.

in addition to political propaganda, Korean military broadcasts to the DPRK include weather forecasts, radio and TV dramas and popular songs, such as "Heart" by IU, "Speak Your Wish" by girlhood and "BANG BANG BANG" by Bigbang.

A South Korean military officer who was in charge of broadcasting to the DPRK recalled that they often observed that if it was going to rain, the Korean army on the other side would take away their clothes. According to the Central Daily News, this means that the Korean people are not turning a deaf ear to the Korean military broadcast.

Psychological warfare has become a weather forecast, and this effect is probably unexpected in South Korea.
