Russian Woodpecker
photo: Duga-3 array within the Chernobyl Exclusion Zone. The array of pairs of cylindrical/conical cages on the right are the driven elements, fed at the facing points with a form of ladder line suspended from stand-off platforms at top right. A backplane reflector of small wires can just be seen left of center, most clearly at the bottom of the image.
The Russian Woodpecker was a notorious Soviet radio signal that could be sporadically 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, commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. Because of its extremely high power output (over 10MW in some cases), the signal became such a nuisance that some receivers such as amateur radios and televisions actually began including ‘Woodpecker Blankers’ in their design.
The mysterious and unclaimed signal was a source for much speculation, giving rise to theories such as Soviet mind control and weather control. However, after careful study, many experts and amateur radio hobbyists long believed it to be that of an extremely powerful 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 (Russian: Дуга-3) [1] 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.
