wonder if they took the russian woodpecker grid down. . . Duga (Russian: ะ”ัƒะณะฐ, literally "arc" or "curve") was a Soviet over-the-horizon radar (OTH) system used as part of the missile defense early-warning radar network. The system operated from July 1976 to December 1989. Two operational duga radars were deployed, one near Chernobyl and Chernihiv in the Ukrainian SSR (present-day Ukraine), the other in eastern Siberia.

 

The duga systems were extremely powerful, reaching over 10 MW, and broadcast in the shortwave radio bands. They were nicknamed Russian Woodpecker by shortwave listeners for their emissions randomly appearing and sounding like a sharp, repetitive tapping noise at 10 Hz rate.[1] The random frequency hops disrupted legitimate broadcasts, amateur radio operations, oceanic commercial aviation communications, and utility transmissions, resulting in thousands of complaints by many countries worldwide. The signal became such a nuisance that some receivers used on amateur radio and television, began including "Woodpecker Blankers" in their circuit designs.[2]

 

The unclaimed signal was a source for much speculation, giving rise to theories such as Soviet mind control and weather control experiments. However, because of its distinctive transmission pattern, many experts and amateur radio hobbyists quickly realized it to be an over-the-horizon radar system. NATO military intelligence had already given it the reporting name STEEL WORK or STEEL YARD likely based on the massive size of the antenna which spanned 700 metres (2,300 ft) in length and 150 metres (490 ft) in height.[3] While the amateur radio community was well aware of the system, this theory was not publicly confirmed until after the dissolution of the Soviet Union.
