For those too young to remember, the "woodpecker" was a Soviet-era early warning radar system built to detect incoming nuclear missiles from the United States. Its tapping signals caused havoc on the HF ham bands as they swept through the shortwave spectrum. Chernobyl, of course, is the site of the world's worst nuclear power disaster in 1986 and the Duga-1 array is within the Chernobyl Exclusion Zone. It is speculated by some that the Chernobyl power plant was built primarily to provide electricity to the Duga radar.
