A closer look
If you love the idea of a Cold War relic ominously buzzing into the void for decades just to prove it isn't dead, tune into 4625 kHz. The UVB-76 'Buzzer' is a Russian shortwave radio station that has been broadcasting an endless, monotonous drone since the 1970s. Every few years, a live voice interrupts to read a meaningless string of names and numbers. It operates as a 'Dead Hand' marker—a signal designed to let the military know the network is still active, or perhaps to trigger a doomsday response if the buzzing ever stops.
