A chilling new signal believed to be tied to Iran has begun appearing across the radio spectrum in Europe, with shortwave listeners in the United Kingdom reporting mysterious encrypted broadcasts shortly after the death of Iranian Supreme Leader Ayatollah Ali Khamenei.
Amateur radio enthusiasts say the transmissions resemble a classic “numbers station,” a type of coded broadcast historically associated with espionage and covert intelligence operations.
The signal has been designated “V32” by the monitoring group ENIGMA2000, which tracks suspected intelligence transmissions around the world.
Shortwave listeners say the station broadcasts strings of encrypted numbers late at night and early in the evening.
The transmissions have reportedly been heard clearly across the United Kingdom and parts of Europe, with signals bouncing off the ionosphere and appearing on the frequency 7910 kHz (7.910 MHz) in Upper Sideband mode.
Monitors have described the broadcast as a male voice, possibly synthetic, speaking in Farsi while reading out sequences of numbers.
