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, http://no.nonsense.ee/qthmap/?qth=FK81BD&from=jn49ik00wd
