LF,
A short amendment to the recent results by Edgar and me:
Edgar even recorded the session of that evening and provided a wav file
for me which allowed to reprocess the signal. I tried to get some
better view (adjustment of B, C sliders and colour palette) of the
signal, see attached image.
I also found that the best S/N was better than 15 dB in 10.2 mHz FFT
bin width.
BTW i would like to see the captures of the No.1...No.4 of LF record
distance detections which are shown in
http://136.73.ru/h_qso/index.htm. Where can i find these captures?
Maybe R7NT knows the answer?

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

The path is 16806 km,

It shows once again that it is always worth to transmit and to
receive/watch for exceptional conds(x) on the bands!
Many thanks to Edgar for his continuous patience and interest to
receive on 137 kHz from the other side of the world!
