A great article, Mark. Thanks for sharing with us. There was a new term that I had never heard of before, and perhaps someone smarter than me can explain it further: Gyrofrequency. The map didn't have much information for North America compared to other places in the world, and was quite high, into the X-band here. I'll have to re-read it to see whether I grasp that concept. Ducting, which we were all familiar with in MW DXing is prominent in the article I'm not quite finished all of it, yet....Walt
