Remember the “Woodpecker” noise on the shortwave bands during the 70’s, 80’s and 90’s? The Soviet Union or U.S. were using some type of over-the-horizon radar that made a woodpecker like noise across multiple shortwave frequencies. It use to mess up shortwave reception or at least make it difficult to listen to programs as the woodpecker noise faded in and out along with the program.

Someone earlier in the thread posted pics of the radar that caused the "woodpecker" sounds and a link to the article on Wikipedia, which has a recording.

To me it sounded more like a helicopter than a woodpecker.

To me it sounded more like a helicopter than a woodpecker.

I think that's because it was mixed with the WWV signal.

I heard it many times during the 80's, in an otherwise clear band. It was a much sharper impulse noise.
