LF, =

Last=20 evening there was excellent LF propagation from EU to VK. Edgar J. = Twining=20 (SWL) was watching the LF DX window for several weeks now. The season = on that=20 path in spring (EU) 2013 was very poor and we already thought that the = season=20 is over. However yesterday the path was open for a exceptional long = time and=20 the S/N was very good! Transmissions were done in DFCW-180. I've been = on air=20 for several days now and such a result is most probably possible for 1 = time in=20 the year or maybe 2 years.

These are the results:
