A mystery Russian radio station has ‘buzzed’ every day since the 70’s and no one knows why

Since the 1970’s a mystersious—ghostly—Russian Radio station has been emitting a strange ‘buzzing’ noise along with the intermittent code of words and numbers. No one claims to run the station referred to as the Buzzer. The mysterious shortwave radio station broadcasts on the 4625 kHz band.

The exact purpose of the station has not been confirmed by government or broadcast officials.

Until this day, no one knows who or what is broadcasting the signal, which has resulted in countless theories ranging from secret Russian military bunkers to alien messages.

The station is commonly referred to as The Buzzer, UVB-76 and more recently MDZhB. The signal seems to originate from a mysterious station located in the middle of a Russian swampland near the city of St. Petersburg, but before being moved to St. Petersburg, the station’s transmitter was located near Povarovo, Russia, around 10 kilometers northwest of Moscow. The truth is that throughout the years, the radio station seems to have switched locations, perhaps in an effort to remain anonymous.

The radio signal occupies a frequency of 4625 kHz and has been transmitted by the mysterious Russian ghost radio since the late 1970s. Anyone can tune into the signal.

Since then, the shortwave radio has begun to emit a repetitive buzz. Rarely (once a week), the buzz stops, and a voice reads a mixture of Russian numbers and names. Nobody knows what the messages mean in Russian, nor does it emit whistles nor material from the Soviet Union’s golden age.

Over time, more and more people have become obsessed with discovering the mystery behind the signals, but not even today has anyone been able to crack the mystery.

There is much speculation about the nature and reason of the radio emissions, but nevertheless, the true objective of this radio station is still a mystery.

The station transmits a humming sound that lasts for about 0.8 seconds, pausing from 1 to 1.3 seconds and then repeating from 21 to 34 times per minute.

One minute before each hour, the repeat tone is replaced by a continuous tone, which continues for one minute until the tone repeats the sequence again.

It is known that from 7:00 to 7:50 GMT, the station transmits with low power consumption. Probably when transmitter maintenance occurs.

The sound generated by the station reminds one of a radio squeal along with the bustle of a boat.

Instead of silencing emissions with the fall of the USSR, the station has become even more active. For at least a couple of decades, voice messages on the radio are becoming more frequent.

It is easy to discard the signal as pre-recorded or looped.

The buzzing seems to be generated manually. The likely reason for the conversations is that the loudspeaker that creates the noise is constantly placed next to a microphone, giving the world a strange view of the mysterious signal source.

This phenomenon became worldwide, and all of those who love the paranormal became extremely interested in cracking the mystery behind the “Buzzer.”

While no one has been able to solve the mystery yet, many talk about alien activities in the area, and even of ghosts that generate the signal and strange voices.

Finding the Buzzer

The transmitter of the station was located in Povarovo, Russia, which was halfway between Zelenograd and Solnechnogorsk about 40 km from Moscow and 10 km north of Zvenigorod but was eventually moved to the middle of a Russian swampland near the city of St. Petersburg, where the station seems to operate from today. The location and call sign was unknown until the first voice transmission in 1997.

The only thing that seems certain is that there is too much speculation, but the purpose of the emissions remains a mystery even today.

    I could tell the author of the post, what is this station used for, but I’m afraid you could get a bit shocked 😉

      Omg, please do tell.

  • It’s a type of mores code, info is going out. To who and where from as well as the content may be a mystery. But I bet on a similar neighboring freq there is a return signal. Best way to transmit sensitive data is in plain sight. Of course without a code legend you wont know what that data means. Being it has been moved around. It most likely is counter intel, and also the known sending source is most likely a mirror. Hiding the origins of th signal. Still pretty weird in todays world.

      Seems you don’t know much about propagation of HF signals. And no, it’s not a “type of mores [sic] code”. The location of the transmitter(s) is known by simple direction finding outside Russia.

      The pulses have been laboriously analysed by many IT and communications experts. There appears to be no data, just repetitive pulsing.
