N4II's very informative Webinar has been posted to the World Wide Radio
Operators Foundation (WWROF) web page.
"The 2013 VK9CZ DXpedition to the Cocos (Keeling) Islands made 51 QSOs with
US Zone 5 on 80m. 21 of these QSOs – more than 40 percent – were with
stations in Florida. This presentation discusses several possible
propagation mechanisms for this grayline event, and concludes that
propagation through the dark ionosphere, rather than along the grayline
itself, was the responsible mechanism."
