Hi Markus,
Unfortunately you where = already QRT befor=20 the propagation got better. You'r right, perhaps propagation = to your=20 direction is differend in relation between Uwe and my QTH.
If you take a look (in my grabber) = at DJ8WX his=20 signal and you's, there is not much difference.

Perhaps it is possible for you to switch = on a few=20 hour between sunset and sunrise !
