Duga 3



his gigantic radar system was build in the early 70's as an missile detection system.

As for sure it has many manes like Chernobyl 2 or the Woodpecker because of it's repetitive tapping noise at 10 Hz.



"The Russian Woodpecker was a notorious Soviet signal that could be heard on the shortwave radio bands worldwide between July 1976 and December 1989. It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name. The random frequency hops disrupted legitimate broadcast, amateur radio, utility transmissions, and resulted in thousands of complaints by many countries worldwide. The signal was long believed to be that of an over-the-horizon radar (OTH) system. This theory was publicly confirmed after the fall of the Soviet Union, and is now known to be the Duga-3 system, part of the Soviet ABM early-warning network. NATO military intelligence had photographed the system and given it the NATO reporting name Steel Yard."
