It is dark long enough anyways now in Europe and I beleive the sea-water path should enable 24/7 reception if being part of the equation here.

The longer darkness and sea-water path perhaps not being the most important factors. It is dark long enough anyways now in Europe and I beleive the sea-water path should enable 24/7 reception if being part of the equation here. I put my bets on higher QRN and background noise, although there must be some places in central Europe where the man-made background noise is unsignificant. My QTH also has a noise handicap in the order of at least 10dB when it comes to daytime reception on MF, I would not know what the empty band sounds like daytime, had I never brought some RX-gear along to more remote places. Same antenna and RX used in both cases just to be sure. Those who swear by large wire antennas for RX on MF should know they are lucky, because that is probably a good sign of living in a relatively RFI-free environment.
