UVB-76 - "The Buzzer", recorded on 24 March 2022
UVB-76 (Russian: УВБ-76; see other callsigns), also known by the nickname "The Buzzer", is a shortwave radio station that broadcasts on the frequency of 4625 kHz.[1][2] It broadcasts a short, monotonous buzz 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 start date of broadcasting is disputed. However, it was allegedly reported to have started broadcasting in the late 1970s,[4] possibly 1976.[5][6]
