Hello Jim,

Based on the coordinates the Saarlouis TX should be in JN39IG and according
to the Buckmaster callbook ZL2CA is in RE78JQ.
That makes the distance 18630km and direction 51 degrees for the short path
and 21370km / 231 degrees for the long path (directions seen from Europe).
Assuming the better propagation over the night side of the earth shortpath
should occur in the EU evening (= ZL morning) and longpath in EU morning (=
ZL evening).

The Europe 1 antennas should favour longpath, but Bob's copy (at ZL
sunrise) would be shortpath ?

Dear LF Group,

Looking at the Europe 1 web pages suggested by F1TAY, and if my understanding of the french is correct, the 183kHz signal is transmitted using a 4 element array beaming south west on a bearing of 220degrees. This would seem to favour propagation via a long path to ZL - is this consistent with ZL2CA's reception in the morning? The ERP of the signal going the other way over the north pole must be much lower.
