Hello Stefan. Sorry but I do not understand.
 
Can you explain to us scientifically why
you said that there is a difference enter winter and summer for day time groundwave mode of propagation ?
 
Also, an other question : can you tell us honestly which is your exact EIRP transmitting power, because on day time groundwave there is not usual to have a WSPR2 report on the 630 meters band of –17 dB S/N over 1500 km (Remember that he legal maximum power in DK is 1 Watt EIRP, and nobody can ignore the law ).
 
73 Andy.

Hi MF,

I just sent a single WSPR block and got the following results from distances above 300km.
 This is typical for the winter season.

73, Stefan
