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.
