"UVB-76 is the callsign of a shortwave radio station that usually broadcasts on the frequency 4625 kHz (AM full carrier). It's known among radio listeners by the nickname The Buzzer. It features
a short, monotonous buzz tone (help·info), repeating at a rate of approximately 25 tones per minute, for 24 hours per day. The station has been observed since around 1982. In rare occasions, the
buzzer signal is interrupted and a voice transmission in Russian takes place. Only four such events have been noted. There is much speculation; however, the actual purpose of this station remains
unknown." Inspiration for Lost?
