Propagation from Scandinavia was very poor/non-existant. Even close by stations e.g. from Poland were much weaker than usual. One of my propagation markers is NDB VM-375 from Iceland. It is very rare not to hear it, but yesterday evening it was completely gone. At 04:00 UTC this morning, I could only spot a weak trace. The band noise was also very low, which indicates that distant QRN was not propagated very well! All in all quite interesting! 73, Roelof, pa0rdt
