"The best way to control the opposition
is to lead it ourselves."
The Russian Woodpecker was a Soviet radar system used as part of the Soviet ABM early-warning network, located in the Exclusion zone of Chernobyl. The system operated from 1976 to 1989.
During the Cold War, this system was designed to track the launch of missiles with atomic charge and gave this information within two to three minutes to the Soviet leadership. It 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 trapping noise, at 10Hz. The random frequency disrupted legitimate broadcast, amateur radio, and utility transmissions and resulted in thousands of complaints by many countries worldwide.
The town next to the Russian Woodpecker was mostly composed of army buildings, where the workers of the antennas lived alongside their families. It was a very secret military installation and the residents had to apply for visas to leave this zone.
