Stefan and Martin, really a fine job!
I hope to be QRV soon on 137 KHz on my summer beach QTH on the border
of Atlantic Ocean, Long : -50.20297 W (-50° 12' 11'' W) Lat :
-30.17688 S (-30° 10' 37'' S) QTH locator : GF49VT.

Subject: LF: DK7FC in South America
LF!
I just wrote to Martin/YV7MAE:
May, the 15th 2012! 00:12 UTC. YV7MAE received first traces of DK7FC
on 136.172 kHz in DFCW-180. Excellent reception of DCF39 too and low
QRN/M, after several antenna system improvements!
This is a first detection of a German amateur radio signal in South America!
Congratulations!
I can see it live via the remote link, the grabber is still not
updated (each 10 minutes).
After another change in the antenna wire location (higher,
longer..., i can't stop him to improve each day), DCF39 showed up
about 30 dB S/N in 1 Hz NBW (without noise reduction). I started the
TX immediately. After a few minutes i saw my K just 0.1 Hz below
136.172 kHz, as Markus mentioned in the recent days.
It is still the long wire, about 80m, matched with a resonant
circuit on a ferrite rod which Martin is using. If this path works
in the middle of May, what will it look like in winther? And what
when a directional antenna is used?
I still can't belive it!
The capture is now on the grabber and will be saved in the archive
site which a added today.
My God, now the 7 is coming in!!!!!!!!!!!!!!! That is worth ALL the
effort, by far!!!!
The path is 7818 km distant,
