Content preview: 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.

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 https://dl.dropbox.com/u/19882028/LF/DK7FC%2027-8-2012-204.jpg A capture to compare the transmitter side to that time is here https://dl.dropbox.com/u/19882028/LF/EU60_27.AUG_21.15UTC.jpg This is Edgar's DCF spectrogram, showing an open path to that time: https://dl.dropbox.com/u/19882028/LF/DCF39%20plot%2027-8-2012.jpg 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
