UVB-76 is the callsign of a [[sho
There is much speculation; however, the actual purpose of this station remains unknown. , and a male voice speaking Russian announced: "Ya — UVB-76. 18008. BROMAL: Boris, Roman, Olga, Mikhail, Anna, Larisa. 742, 799, 14." The same message was repeated several times before the beep sequence repeated and the buzzer resumed.
- A similar voice message was broadcast on September 12, 2002, but with extreme distortion (possibly as a result of the source being too close to the microphone head) that rendered comprehension very difficult. This second voice broadcast has been partially translated as "UVB-76, UVB-76. 62691 Izafet 3693 8270."
- A third voice message was broadcast on February 21, 2006 at 7:57 GMT. (recording of the third voice transmission) Again, the speaking voice was highly distorted, but the message's content translates as: "75-59-75-59. 39-52-53-58. 5-5-2-5. Konstantin-1-9-0-9-0-8-9-8-Tatiana-Oksana-Anna-Elena-Pavel-Schuka. Konstantin 8-4. 9-7-5-5-9-Tatiana. Anna Larisa Uliyana-9-4-1-4-3-4-8." These names are found in some Russian spelling alphabets, similar to the NATO phonetic alphabet.Cite error: A

UVB-76 is widely believed to be used to transmit encoded messages to spies, as is generally assumed for the many numbers stations that populate shortwave frequencies. Transmitter sites for some numbers stations have been triangulated to military and/or intelligence installations in several countries, although no nation's government will confirm or deny the existence of the stations or their purpose. Another possibility is that the constant transmission of its characteristic sound is supposed to signal the availability, operation or alertness of some kind of installation, a kind of dead man's switch of a military or other installation, possibly for the Dead Hand system.
Another explanation for the constant buzzer is the High-frequency Doppler method for ionosphere research described in the Russian Journal of Earth Sciences, in which radio waves are reflected from ionosphere inhomogeneities. Changes of an ionosphere state can be caused by solar geophysical or seismic events. This method involves comparing a continuous radio transmission which is reflected by the ionosphere with a stable basic generator. The continuously transmitted carrier frequency currently used for this research matches that of the Russian Buzzer (4.625 MHz).
