The video of the array begins at about half way through the video. It appears to be hundreds of phased verticals in front of a circular reflecting screen. Each element of the array appears to be a br

That is a Wullenwber (or Wullenwever) array. See: http://en.wikipedia.org/wiki/Wullenweber It would have probably made one heck of an 80/160 meter receive antenna <G>. The video appears to be one of

Frank: I think the antenna in the video is a former Soviet Union "Cold War" version of a German Wullenweber also known as a Circularly Disposed Antenna Array (CDAA) http://en.wikipedia.org/wiki/Wulle

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

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 st

Since some of these large antenna sites are no longer used it could be an ideal location for a SRD receiver feed (for 160 meters only) and with sufficient delay during contests to avoid their misuse,

Herb: If any organization or individual is fortunate enough to gain access to a CDAA there is no reason to limit use of SDR to 160 meters, any band 160 - 10 would benefit. 73, Jack Since some of thes

That would be great Lee but one system won't be enough, you will need to put up any number of systems so subscribers can be assured what is spotted can be heard in their area... Go for it... 73, Jack
