Coming from somewhere in Russia, a radio station has been baffling interested parties for decades. With its slightly changing, but constant broadcasts, UVB-76 has revealed very few, if any, of its secrets. Sure, its purpose may be as innocuous as a weather station, but the mystery surrounding it is irresistible. Description UVB-76 is named for the start of most of the voice transmissions, at least in its first few decades. More recently, each transmission has begun with the presumed designation MD2hB. This change corresponded with a change in the radio station's rough transmission location. The location is definitely in Russia and was first traced to Povarovo. Now, it is transmitting somewhere near Pskov. The so-called UVB-76 is a radio station operating on the shortwave frequency 4625 kHz. The Russians call it "The Hummer" and others know it as "The Buzzer" because of the sound it currently makes, which started as a blip. It emits about 25 buzz tones per minute at a near-constant rate
