Iran Interference in Secret Code Signal Transmissions - Jamming in Greece-Cyprus

A mysterious shortwave radio transmission, with a male voice reciting numerical sequences in Persian, has been detected, starting on the first day of the US-Israeli attacks on Iran. The transmission, which follows a repetitive pattern, appears to be emanating from a region in Western Europe and is experiencing strong interference (jamming). Experts suggest it may be a “numbers station,” an old Cold War espionage method used to send encrypted messages to agents. However, decoding these signals is practically impossible without the appropriate key. The use of jamming suggests state involvement. There are scenarios involving the US, Israel, or even Turkey as being responsible for the transmission. ABC News reports indicate that US authorities detected an encrypted transmission that may be related to the activation of “sleeper” agent networks. It has been observed that the transmission is receiving strong Iranian jamming from Cyprus and Greece, with the characteristic “bubble jamming” being evident. Additionally, analysts claim that Turkey interfered with electronic warfare means in encrypted signals sent from Europe to Iran.
