It turns out that Russian names, numbers and mysterious phrases were being transmitted on the mysterious Russian shortwave broadcast 'UVB-76'



Russian shortwave radio station UVB-76 , commonly known as 'The Buzzer,' has been broadcasting mysterious messages since the 1970s. The station broadcasts a monotonous buzzer sound 24 hours a day on a frequency of 4625 kHz, but a new, cryptic voice was confirmed to have been broadcast on UVB-76 on September 8, 2025.

The audio broadcast by UVB-76 is shown below. The audio includes not only the buzzer sound, but also Russian names like 'Nikolai,' 'Zhenya,' and 'Tatyana,' as well as several numbers, phrases like 'soft sign' and 'reception,' and code words like 'NZHTI' and 'HOTEL.' 'NZHTI' is the station's call sign, which has been in use since December 30, 2020.



UVB-76 is believed to be a command network belonging to the Western Military District of the Russian military. Its call signs have changed frequently throughout its history, including 'UZB-76' and 'MDZhB.' The name 'UVB-76' is a misnomer of 'UZB-76.' Its transmitter has also moved; it was formerly located in Povarovo, near Moscow, but was relocated to the St. Petersburg area in September 2010. As of this writing, UVB-76 is believed to be controlled from St. Petersburg and broadcast from multiple transmitters in and around Moscow and St. Petersburg.

There are three main formats for the voice messages broadcast: 'Monolith,' 'Uzor,' and 'Komanda.' The most common 'Monolith' format consists of a call sign, a five-digit ID group, a code word, and an eight-digit number. The broadcast confirmed this time appears to have been in this 'Monolith' format.

The true purpose of UVB-76 broadcasts has never been officially revealed, but several theories have been put forward. One is that it is a military communication to ensure that receiving station operators are always paying attention. Another is that it serves as a 'channel marker' to keep the frequency occupied and prevent other broadcasters from using it. There are also rumors that it may be related to the 'Hand of Death' system, which would automatically launch a retaliatory strike in the event of a nuclear attack, but this is considered unlikely due to the frequent interruptions in broadcasts.



In recent years, there have been reports of pirate broadcasts disrupting the network, including popular songs being played. In May 2024, a pirate broadcaster attempted to talk to an operator, who responded with two beeps, saying 'no.' UVB-76 was livestreamed by volunteers on YouTube, and you can listen to it below.
