At least that one was a real decode last night, see attachment.
MF WSPR TA detections are only possible in deep winter (long deep
darkness) or in deep summer (along the grey line) :-) At least this is
WD2XSH/17 is the best hearing MF station there, having the best location
and likely the best equipment too (?).
While the chances for a detection in winter are best during the sunset
on the RX side, the best time during the summer period seems to be just
when the grey line is symmetric between TX and RX.
