The Shortwave Radio Number Station is a myth in Grand Theft Auto V. According to many player reports, while driving through any part of Blaine County late at night, but especially on the border of Los Santos, one will hear Blaine County Talk Radio abruptly turn to static, followed by a robotic female voice reciting random strings of number in monotone. Players report that while driving as Trevor, military chatter can be heard about his past as a Canadian Air Force pilot.
Number stations can also be heard while in the sea in the north.
A number station is a type of shortwave radio station characterized by unusual broadcasts, reading out lists of numbers, or incomprehensible morse code messages. The voices are often created by speech synthesis and are transmitted in a wide variety of languages. The voices are usually female, although sometimes men's or children's voices are used. Some voices are synthesized and created by machines, however, some stations used to have live readers.
In the 1960s, Time magazine reported that the numbers stations first appeared shortly after World War II and were imitating a format that had been used to send weather data during that war. It is widely assumed that these broadcasts transmit covert messages to spies. The Czech Ministry of Interior and the Swedish Security Service, have both acknowledged the use of numbers stations by Czechoslovakia for espionage, with declassified documents proving the same. With a few exceptions, no QSL responses have been received from numbers stations by shortwave listeners, who sent reception reports to said stations, which is the expected behavior of a non-clandestine station.
The Number Station usually appears in Blaine County, particularly on the border of Los Santos County (where Blaine County Talk Radio automatically switches into WCTR). It also appears while flying or sailing out to sea in the far north of San Andreas off the coast of Blaine County. All reports place the event after 23:00, feature white noise lasting longer than usual, and describe a monotonic machine female voice listing off seemingly random strings of numbers under a soft static. The last string of numbers is always '6669', a mixture of the number of the beast and Rockstar's tradition of using the sexual number, 69. Some players report hearing a Microsoft Sam voice listing off numbers and letters.
