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
