Hello Alan,

Thank you for the information.

<= div>However, at this time of the year "full daylight" is something diffe= rent than in June.

There i= s also daytime reception, up to the daily solstice of the sun, over a mu= ch longer path than 4000 km.

YQ-305, Churchil, Canada Manitoba= , is about 5700 km away and YEK-329, Arivat/Eskimo Point, Canada, Nunavi= t 5500 km.

This should be all multi-hop propagation.
