500kHz propagation from western europe sets in very late (early morning) her=
e
now, there is no complete nighttime darkness up here anymore so the D-layer
gets very little rest. Midsummer is about a month away and it will be August
before signals slowly start improving here again on MF.

DI2AM was weak too at the time I had the first copy of Rik.

2200z is local midnight here and mid-path midnight will be almost one hour
later.

So in fact 2125z was still "early" copy of Rik here. I expect signals would=20=
have
improved vastly from that. This is a very typical behaviour for DI2AM signal=
s
during recent weeks.

The opposite situation:

In mid winter I could copy GM4SLV 24/7 on the Shetland - Vaasa path during s=
ome
longer tests we ran.


Will keep an ear on 502.95kHz during the weekend when/if I'm in the shack
