Hello Stefan,

It is a myth that DX on LF is only possible in winter.

I am running a quest to log at least one Canadian NDB every day in 
the Netherlands and the last outage was December 22, 2015 when we 
had a severe magnetic storm.

At present I am at day 1341 since I started and the rare occasions I 
did not succeed were due to geomagnetic storms or severe static!

In fact propagation is now better than last November!

73,
Roelof, pa0rdt
