[CQ-Contest] Webinar - A Long Overdue Review of Gray Line Propagation on the Low Bands

[Ken Claerbout]

The World Wide Radio Operators Foundation (WWROF) is pleased to present A Long Overdue Review of Gray Line Propagation on the Low Bands with Carl Luetzelschwab, K9LA.  Carl will trace the origin of gray line propagation, and show that there is a problem with the current explanation that propagation along the terminator is efficient.  He will then provide an alternative explanation for gray line that satisfies both observations and ionospheric physics.
