“The numbers parks have been calling out to you automatically since less than the first World War. Given that the issue of operating a numerical station is technically a state secret, there have been very few confirmations on the part of government organizations.
Even if the encryption method used for the majority of numerical stations is unknown, some have used and it is believed that others use a libretto of a single use: sum mathematics of a set of random numbers (the key) for the text in the format, that can only be used once, and must be destroyed after use.
It is believed that some stations will transmit predefined code instructions. The numerical parks offer a powerful advantage in our modern world: practically complete anonymity. The recipient of the message could be in any part of the world and receive instructions without fear of being tracked through a telephone call or Internet connection. Everything that the recipient needs is a cut wave radio and in the right place at the right time.
