It broadcasts primarily information in Chinese, Spanish, German, English, French, Russian, Japanese and Arabic.

Operated by the occupying Japanese forces, JBBK broadcast a first and second program as part of Japan's radio network that covered the Korean Peninsula from Seoul.

[citation needed] The station was founded in October 1945 as Radio Pyongyang,[2] and officially inaugurated programming on the 14th, with a live broadcast of the victory speech of Kim Il Sung when he returned to Pyongyang at the end of World War II.

It instead starts broadcasting the interval signal (the first few notes of the "Song of General Kim Il Sung") on the hour.

[citation needed] A typical program line-up begins with the interval signal, followed by the station announcement "This is Voice of Korea".

[2] In 2006, Voice of Korea started broadcasting on 11545 kHz, the same frequency as the former Lincolnshire Poacher numbers station.

Some frequencies are well out of the ITU-allocated shortwave broadcast bands, making them less susceptible to interference and less likely to be listenable on older receivers.

The interruptions have not been explained by Voice of Korea, but they are thought to be due to engineering works at the transmitter sites, faulty equipment or because of power outages.

[8] The off-air periods also affect North Korea's own jamming signals designed to prevent reception of South Korean stations such as Echo of Hope, Voice of the People, and KBS Hanminjok Radio.
