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
