The Russian "Woodpecker" Returns

The International Amateur Radio Union's Region 1 Monitoring System is reporting the return of over-the-horizon radar signals originating from Russia on the 20, 15 and 10-meter bands. Similar signals disrupted the ham bands during the Cold War and at the time were dubbed the Russian "woodpecker" because of the rat-a-tat-tat sound the signals make. According to Newsline, the report also cites ongoing interference from Russian taxicab drivers using FM on the low end of 10 meters.
