Topband: Webinar - "Grayline Propagation, or Florida to Cocos (Keeling) on 80m"

[Ken Claerbout]

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."
