Voice of Korea
In the past, the station broadcast coded messages to North Korean spies. This practice ended with the 2000 June 15th North–South Joint Declaration. In 2006, Voice of Korea started broadcasting on 11545 kHz, the same frequency as the former Lincolnshire Poacher numbers station. While it is unknown whether this was an intentional effort to interfere with Poacher's propagation or an accident, it is not unknown for Voice of Korea to unintentionally jam its own signal by transmitting programmes in different languages simultaneously on the same frequency.
