Russian Buzzer on 4625kHz
UVB-76
https://en.wikipedia.org/wiki/UVB-76
UVB-76, also known as "The Buzzer", a nickname given by radio listeners to a shortwave radio station that broadcasts on the frequency 4625 kHz.[1][2] It broadcasts a short, monotonous About this soundbuzz tone (help·info), repeating at a rate of approximately 25 tones per minute, 24 hours per day.[1] Sometimes, the buzzer signal is interrupted and a voice transmission in Russian takes place.[3] The first reports were made of a station on this frequency in 1973.
Location and function
The purpose of the station has not been confirmed by government or broadcast officials. However, the former Minister of Communications and Informatics of the Republic of Lithuania Rimantas Pleikys has written that the purpose of the voice messages is to confirm that operators at receiving stations are alert.[6][21][22] Other explanations are that the broadcast is constantly being listened to by military commissariats.[23]
There is speculation published in the Russian Journal of Earth Sciences which describes an observatory measuring changes in the ionosphere by broadcasting a signal at 4625 kHz, the same as the Buzzer.[24]
It is also speculated that the voice messages are some sort of Russian military communications, and that the buzzing sound is merely a "channel marker" used to keep the frequency occupied, thereby making it unattractive for other potential users.[1] The signature sound could be used for tuning to the signal on an old analogue receiver. The modulation is suitable to be detected by an electromechanical frequency detector, similar to a tuning fork. This can be used to activate the squelch on a receiver. Due to the varying emission properties on short-wave bands, using a level-based squelch is unreliable. This also allows a signal loss to be detected, causing an alarm to sound on the receiver.
Another theory, described in a BBC article, states that the tower emits a “Dead Hand” signal that triggers a nuclear retaliatory response if Russia were hit by a nuclear attack.[4]
There are two other Russian stations that follow a similar format, nicknamed "The Pip" and "The Squeaky Wheel". Like the Buzzer, these stations transmit a signature sound that is repeated constantly, but is occasionally interrupted to relay coded voice messages.[1]
The former transmitter was located near Povarovo, Russia,[1][25] at 56°5′0″N 37°6′37″E which is about halfway between Zelenograd and Solnechnogorsk and 10 kilometres (6.2 mi) northwest of Moscow, near the village of Lozhki. The location and callsign were unknown until the first known voice broadcast of 1997.[26] In September 2010, the station's transmitter was moved to the nearby city of Saint Petersburg, near the village of Kerro Massiv. This may have been due to a reorganization of the Russian military. Prior to August 9, 2015, the station is not transmitted from the Kerro Massiv transmitter site ("Irtysh") anymore, possibly due to a reorganization of the Russian military for the particular area which may cause the frequency to be used only in the Moscow Military District. At present, The Buzzer appears to be broadcast only from the 69th Communication Hub in Naro Fominsk, Moscow.[3] In 2011, a group of urban explorers explored the abandoned buildings at Povarovo.[27][28] They claim that it is an abandoned military base. A radio log record was found, confirming the operation of a transmitter at 4625 kHz.[27][29]

'Dead Hand': Russia's Nuclear Weapon System with 1 Terrifying Feature
It would automatically launch missiles—without the need for a human to push the button—during a nuclear attack.
