A radio station that no one claims to run (2017)

While you’d be hard pressed to listen to a local station such as BBC Radio London in a neighbouring county, shortwave stations like the BBC World Service are aimed at audiences from Senegal to Singapore. If you want to absolutely guarantee that your station can be heard on the other side of the planet – and if you’re using it as a cue for nuclear war, you probably do – it’s important to change the frequency depending on the time of day, to catch up. Enter the “numbers stations” – radio stations that broadcast coded messages to spies all over the world.
