A Mysterious Code Is Being Broadcast on Shortwave Radio. Is It Iran?
www.theatlantic.com

... On February 28, the day that bombs started falling on the Islamic Republic, a man's voice began broadcasting in Farsi on a shortwave-radio frequency. He announced himself""Tavajjoh! Tavajjoh!" (Attention! Attention!)"and then read a string of seemingly random numbers. Anyone with a shortwave radio could hear him. But the announcer's intended audience was likely no more than a handful of people using a centuries-old system to decipher his otherwise incoherent message. ...

Random Numbers, Persian Code: A Mysterious Signal Transfixes Radio Sleuths -- And Intelligence Experts

... The radio signal first started broadcasting on February 28, about 12 hours after the United States and Israel began bombing Iran.

On a scratchy shortwave signal almost twice a day -- in the early morning and early evening on Coordinated Universal Time -- a man's voice can be heard speaking Persian, counting out a series of apparently random numbers. The numbers are read out for varying stretches of time, followed by a pause in which the word tavajjoh -- which translates as "attention" -- is spoken three times. ...

Numbers station
en.wikipedia.org

... A numbers station is a shortwave radio station characterized by broadcasts of formatted numbers, which are believed to be addressed to intelligence officers operating in foreign countries.[1] Most identified stations use speech synthesis to vocalize numbers, although digital modes such as phase-shift keying and frequency-shift keying, as well as Morse code transmissions, are also used. Stations may operate on set schedules and frequencies in the high-frequency band, while others broadcast at irregular times.[2]

Numbers stations have been documented since at least World War I and reached peak activity during the Cold War.[3] Several espionage prosecutions have confirmed the practice: the conviction of the Cuban Five in the United States in 2001,[4][5] and the arrest of members of the Russian Illegals Program in 2010,[6] both involved the use of shortwave number broadcasts to transmit instructions to agents.[7] Messages are typically encrypted using a one-time pad, a method considered theoretically unbreakable when applied correctly.[8]

Shortwave signals can propagate over intercontinental distances by reflecting off the ionosphere, allowing a single transmitter to reach agents worldwide. The receiving agent requires only an ordinary consumer shortwave radio, possession of which carries a degree of plausible deniability. These properties, combined with independence from satellite and internet infrastructure, have led analysts to argue that numbers stations retain operational relevance even in the 21st century.[9]

Numbers stations have long been monitored by shortwave listeners, and many are known by informal nicknames based on distinctive interval signals. Hobbyist groups including ENIGMA 2000 have also developed systems for classifying identified stations.[10][11] ...
