Mysterious Radio Station Has Been Broadcasting Continuously Since 1982 and No One Knows Why

MDZhB is the name of a mysterious radio station that's been broadcasting for nearly four decades, and no one has ever claimed to operate it. For 24 hours a day, 7 days a week since 1982, MDZhB — pronounced MJB — has been broadcasting a dull, monotonous tone followed by a second, foghorn-like sound every few seconds. A couple of times each week, someone will also utter some random phrase in Russian, like “dinghy” or “farming specialist," and then the droning sound returns. The mystery of MDZhB has fascinated radio enthusiasts around the world for centuries, and theories regarding its purpose range from a nuclear war triggering device to communicating with aliens. The most plausible of all theories is that MDZhB acts as a ‘Dead Hand ” signal. In the case of a nuclear attack on Russia, the station would stop emitting, triggering an automatic nuclear response from the Motherland. All anyone knows for sure about MDZhB is that it’s emitting out of two locations in Russia — one in the area of St. Petersburg and another in Moscow. The radio operates at a relatively low frequency known as "shortwaves" that travels long distances, so virtually anyone in the world can listen to it by simply tuning a radio to the frequency 4625 kHz. So far, no one has been able to crack the mystery of the odd radio station.
