There’s a Russian radio station that has been buzzing for decades
On 4625 kHz, a shortwave station nicknamed The Buzzer broadcasts a monotonous buzzing sound almost continuously.
Every once in a while, the buzzing stops and a voice reads strange combinations of names, words and numbers in Russian.
The station has been heard for decades and appears to be connected to Russian military communications, but its exact purpose has never been publicly confirmed.
People have attached all kinds of conspiracy theories to it, including the famous “Doomsday Radio” story, but there’s no evidence that it controls nuclear weapons.
What I find creepy is much simpler: you can still tune a radio to the frequency and hear it.
