Paul, Markus,
Stefan,
thanks for report.
Stefan, any decode?
 
  I come up with the idea of  changing the antenna from TX… to RX…
   
  that means changing the
the matching point of from five Ohm to abt five kOhm and 
   
  retuning the antenna.
   
  question: should I do so?

  Hello Uwe,
  
It looks like i can see your transmission on my VLF forest remote
grabber, 
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html
The signal is well visible in the 'DFCW6000' window! In the city, i
just see QRN/QRM. That is a nice first trace of amateur signals there
(except my own of course).
1PPS+NMEA is running stable since a few days.
I'm now starting to try to decode you both.
  
73, Stefan
