Mysterious Radio Messages and Covert Communication in the Iran-US-Israel Conflict

As tensions escalate between Iran, the United States, and Israel, a peculiar phenomenon has emerged: the broadcasting of coded messages via short-wave radio. These transmissions, reminiscent of Cold War-era spycraft, have sparked curiosity among radio enthusiasts and intelligence experts alike, raising questions about their purpose and intended recipients.

The Emergence of “V32” and Other Signals

Since shortly after the US and Israeli strikes on Iran on February 28, 2026, a mysterious signal labeled “V32” has been detected. The broadcast begins with the Farsi word “Tavajjoh!” (Attention!), repeated three times, followed by sequences of numbers read aloud according to reports. Another signal, broadcasting since February 28th – approximately 12 hours after the start of the bombing campaign – consists of a man’s voice counting out a series of apparently random numbers in Farsi, also prefaced with “tavajjoh” as detailed by Radio Free Europe/Radio Liberty.

Echoes of the Cold War: Numbers Stations

These broadcasts bear a striking resemblance to “numbers stations” – encrypted one-way communication systems historically used by intelligence agencies to send instructions to covert agents. Former intelligence officials suggest these transmissions could be a backup communication method for sources operating within Iran as noted by the Financial Times. The technique involves converting numbers into letters using a pre-shared “one-time pad,” creating an unbreakable code if properly implemented as explained by The Atlantic.

Jamming and Signal Origins

The Persian-language transmission began experiencing jamming on March 4, 2026, with electronic noise disrupting the signal. This suggests an attempt to prevent the intended recipient from receiving the message according to Akin Fernandez, an authority on numbers station technology. Signal triangulation suggests the transmission originates somewhere in Western Europe, though the exact source remains unconfirmed .

Why Radio in the Age of AI?

In an era dominated by digital communications, the resurgence of short-wave radio as a covert communication tool may seem counterintuitive. However, it offers a resilient and potentially untraceable method of communication, particularly valuable in a conflict zone where digital infrastructure may be compromised or monitored. It serves as a “perfect fallback” for maintaining contact with agents when other methods are unavailable .

The Broader Context of Asymmetric Warfare

The use of numbers stations points to a broader pattern of asymmetric warfare employed by Iran, involving unconventional attacks and reliance on covert operations . While digital encryption and internet-based systems have largely replaced traditional methods, the enduring utility of numbers stations demonstrates the continued relevance of low-tech, high-security communication strategies.

The broadcasts run twice daily at 5:30 am and 9:30 pm Iranian time and last around 90 minutes.
