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,
