The UVB-76 radio station, known as “The Buzzer”, again aroused anxiety among international observers, after sending four cryptic messages within 24 hours, on April 15, 2025, writes The Sun. This short -class station, uninterruptedly active from the 1970s, is operated on by the Russian armed forces and is considered a secret Kremlin communication channel.
It is assumed that it could be the last line of defense of an empire that does not want to be forgotten.
Since its early 1970s, when it was used by the KGB to send secret messages during the Cold War, the UVB-76 radio station has never ceased to pamper 4625 kHz, except that recently, this humming has become more sinister. On April 15, during only 24 hours, “The Buzzer” sent four cryptic messages: “Neptun”, “Timus”, “FoxCloak” and “Nootabu”. The signals, closely monitored by the UVB-76 Logs Telegram channel, are particularly rare and leave room for many speculation.
Even if the significance of these words remains a mystery, many bind them with secret military operations or even nuclear protocols. There is talk of UVB-76 as a military communication tool, intended to reach isolated stations or to activate special units in a moment of extreme crisis. Some go further, suggesting that they may be part of a system known as the “death switch”, meant to automatically trigger a military response in an attack on Russia.
UVB-76 constantly transmits its signal, a continuous buzz, 24 hours a day, 7 days a week. This may seem trivial to some, but it's not. It is a signal that goes through the space, transmitted on a high frequency frequency (HF) and available to be listened to by anyone in the signal coverage, stretching for a long distance, from Indochina to the big cities of European Russia. Without satellites, without the Internet, this type of transmission remains a radar communication path, a channel that can be used to transmit sensitive information in the case of a major crisis.
Professor David Stuples, an expert in military electronics, first heard about this mysterious frequency in the 1990s. He explains that the UVB-76 operates on a high frequency tape (HF), which can be received throughout Russia, without depending on satellites or internet.
“The signal does not leave the atmosphere, but is reflected by the ionosphere, covering the whole country”, said Stuples.
In the case of a nuclear war, when other methods of communication could be destroyed, this frequency could work normally, giving the Kremlin a safe way of transmitting orders.
The recent activity of the UVB-76 station deepens the mystery around it, fueling speculation on its role in the Russia's defense strategy. In the absence of official information, it remains a fascinating enigma for radio enthusiasts and international observers.
Conspiracy theories about UVB-76
Spy communications: One of the most widespread theories is that UVB-76 is used by Russian information agencies to communicate with spies. The repetitive sound of the buzz could be a marker to maintain the occupied frequency, the occasional vocal messages being coded instructions for undercover agents.
The nuclear switch of the deadI: Another theory proposes that UVB-76 be part of a “dead man switch”, which could automatically trigger a nuclear response if the station were disconnected. This would act as a discouragement factor, ensuring a respondent attack even if the control and control system were destroyed.
Mental control experiments: Some believe that the station is involved in psychological operations or mind control experiments. It is believed that the strange buzz and periodic vocal messages are part of an attempt to influence or control the minds of the listeners, either generally or of particular persons.
Time trips and parallel universes: Among the strangest theories are the idea that UVB-76 is a timely communication tool or access to parallel universes. The mysterious and apparently absurd shows of the station are interpreted as messages from other times or dimensions.
Extraterrestrial communications: A more marginal theory suggests that UVB-76 is a communication with extraterrestrial beings. Unusual sounds and sporadic messages are considered by some to be attempts to communicate with aliens or receive messages from them.
Scientific experiments: There are also speculation that the station is part of scientific research, possibly related to ionospheric studies or the modification of the time. The consistent signal could be used to study atmospheric conditions or to experience time control technologies.
