For decades, numbers stations have been a staple of espionage (allegedly), characterised by monotonous voices reading out numeric sequences believed to be instructions for undercover intelligence officers.
This new Iranian signal follows that haunting tradition, with reports from monitors like IZ0KBA Lorenzo identifying a male voice – likely synthetic – delivering sequences in Farsi. Listeners have noted a distinct dual-tone beep occurring every three seconds beneath the voice, a signature of modern clandestine transmissions.
The signal has been logged with surprising clarity across the UK and Europe, bouncing off the ionosphere to reach listeners on the frequency of 7910 kHz (7.910 MHz) in what is known as the Upper Sideband mode.
According to reports from the Covert Access Team and other signals intelligence monitors, the broadcasts typically occur twice daily at 2am and 6pm. While the station is being labelled an "Iranian" numbers station due to the language used, technical analysis suggests a more complex reality.
This has led some experts to speculate that the station might actually be operated by a foreign intelligence agency sending messages to assets or resistance groups inside Iran during the current instability.
The appearance of V32 is particularly significant because 7910 kHz sits outside major broadcast bands, typically reserved for military and diplomatic traffic – experts have claimed in various online blogs.
As the mysterious voice continues its daily broadcasts, the amateur radio community remains on high alert, logging every sequence in hopes of spotting a pattern.
For now, the transmission on 7.9 MHz remains a ghostly, coded reminder that in the shadow of a fallen regime, the most sensitive communications are still being whispered across the radio waves by enemy nations such as Iran and even sometimes Russia.
