Topband: Amazing Video of an extremely large circular array

[Charlie Young]

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.

> The Soviet Krug array was a much smaller than the array in the video, nearly identical to the World War II German Wullenweber array. The Krug construction techniques were far different and much less expensive than those shown in the video.
