You're on to something here. I followed some information from the SSGeos website and found that they appear to use work done by a guy who is revered among astrologers, John H Nelson. I had never heard of the guy but it looks like he is a big cheese of early 20th century astrology believers who liked his studies on the effects on short-wave radio propagation under the influence of planetary alignments. I think this is another case of a blind squirrel finding a nut. It's bound to happen once in a while.
