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 three such events have been noted.

Este plina lumea de aceste statii. Se presupune ca sunt sisteme Dead Hand. Daca se opreste transmisia se presupune ca patria mama a fost distrusa si rachetele automate nucleare se lanseaza. Din fericire e doar o teorie. Probabil ca sistemele dead hand folosesc o tehnologie mai complexa in zilele noastre.
De asemenea exista si asa zisele "Number Stations" care sunt folosite pentru a transmite mesaje spionilor.
