I started hearing the Woodpecker on 20M at NSGA Bremerhaven, on the North Sea coast, in the late 1960's. It would completely peg the S Meter and wipe out every signal on the band. Even the Italian stations on 20M SSB, who were usually 20 to 40 over S9, could not make it through. I don't know if the system was operational that early or if they were just testing it. 73 Charlie N8RR
