"Numbers stations" are real-life phenomena that arose in the Cold War era and are far too bizarre for fiction to pass up on.
Simply put, numbers stations are shortwave radio stations that broadcast long strings of numbers, usually read by a synthesized female (or occasionally male) voice. It is generally assumed that the numbers are messages encoded using the one time pad technique, sent by intelligence agencies to their agents in the field. No agency has acknowledged these transmissions, and decryption of a one-time-pad encoded message without the key is impossible. Mostly.
Aside from their use in Spy Fiction, many works of fiction will try to explain these broadcasts as part of some secret plan by a government or other sinister organization, and the Conspiracy Theorist or radio hobbyist will be obsessed with decoding them. Beyond that, they can be used for the creepy effect of having a static-y radio with a lone automated voice repeating gibberish endlessly. One popular theory has it that the creepiness is their entire purpose: plant one next to a country you don't like, and their paranoid government will waste a lot of time and money decrypting total nonsense.
- In Banshee Chapter, numbers stations are broadcasted from another dimension and contain the chemical formula of DMT-19, a (non-existent)note drug that was used in the MK-Ultra experiments. DMT-19 turns the brain into a radio receiver so that otherworldly beings can inhabit humans and "wear them".

- In Lost, the Island has a radio tower that broadcasted a man's voice reading the Arc Numbers 4 8 15 16 23 42 over and over, until Danielle replaced it with her distress call. The Alternate Reality Game The Lost Experience explains that the numbers are the core numerical values in the Valenzetti Equation, an equation that predicts the amount of time remaining until the human race destroys itself. The DHARMA Initiative built the broadcasting tower to transmit the numbers to their backers and if the numbers changed it would prove that DHARMA's work on the island could manipulate the equation.
A radio transmitter has also been erected on the island broadcasting in a frequency and encryption known only to us. The transmitter will only broadcast the core numerical values of the Valenzetti Equation. When, through your research, you manage to change the numerical value of any one of these factors, when you have created through science the [inaudible] ... We will know that the one true way has been found.
