    The Russian Woodpecker

    Post by DX-er on Mon 23 Aug 2010, 00:20

    The soviet over-the-horizon radar "Duga-1" near Chernobil.









    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. This was something that NATO military intelligence was well aware of all along[citation needed], having photographed it and given it the NATO reporting name Steel Yard.
