  Hello Alan,


  Thank you for the information.
  That implies at least two hops and the second reflection point in full =
daylight.
  However, at this time of the year "full daylight" is something =
different than in June.
  I gather that in December/January the density of the D-layer is less =
than in June.


  There is also daytime reception, up to the daily solstice of the sun, =
over a much longer path than 4000 km.
  YQ-305, Churchil, Canada Manitoba, is about 5700 km away and YEK-329, =
Arivat/Eskimo Point, Canada, Nunavit 5500 km.
  This should be all multi-hop propagation.


  73,
  Roelof, PA0RDT
