Hi Stefan, good, the conditions have been "fair" over the last month but no
really big geomagnetic events. My thought is that it will get better, if
this "quiet" continues, up to the end of next month or maybe a little
longer. The equinox probably gives the best night-time conditions for a
N-toS hemisphere path. Stick with it!

Subject: LF: Improving LF path to VK
LF,
It looks like the LF path to VK is now much more promising than a few
weeks ago.
I just got informations and images from Edgar J. Twining, a well equipped
SWL in VK7. He is the one who does the TOP-5 LF DX over a distance of
16805 km (http://136.73.ru/h_qso/index.htm). Edgar is continually
monitoring the LF EU DX window and provides plots and spectrograms of
DCF-39 over that distance.
Today i started the TX very late, as the band already closed again. But i
was wrong. The DCF level dropped but the noise too. So i stopped although
there have still been chances. Anyway he got some traces on the right QRG
to the right time and i was actually transmitting the displayed dashes
(parts of a D), see

to compare the transmitter side to that time is here

This is Edgar's DCF spectrogram, showing an open path to that time:

It is not a very clear proof that these are my traces so we have certainly
to repeat this. However it looks promising :-)
Others may comment.
Just want to pass this info to those who are interested in LF DX, if
receiver, transmitter or lurker :-)
Tomorrow i will start to transmit DFCW-180 on 136.172 kHz again, 18 UTC.
73, Stefan/DK7FC
