I too tried to receive, but is ineffectual. It is necessary to improve RX..

Paul,
 
Stefan's signal is clearly there on your spectrogram.
 
WOW! A dream came true.

Here is an interesting peak on the spectrum,

 http://abelian.org/vlf/tmp/ss100315a.png

Frequency is 8970.0098 Hz +/- 2.5mHz.

Bearing of this signal was 117/297 deg.  Frankfurt is on 114.

I've added a spectrogram to

 http://abelian.org/vlf/nb.shtml

There's a very faint line building up as Stefan continues
his transmission.  Looks like the transmission is modulated
now so the signal has spread a little.

Stefan,
 
congratulations, this is excellent!
 
The distance between us should be a bit over 180 km. I'm amazed at the strength of your signal.

...will be most probably tomorrow, the 15. March.

Due to best wind forecasts, no rain and moderate temperatures i plan to do my 2nd VLF TX test in the afternoon on 8,9700 kHz. It is the first time that the new coil is tested. The variometer part and shielding paint hasn't been attached yet but it will not take much time.

Perhaps there will be some resonating problems but i do not expect them. I try to measure the antenna current and/or the voltage.

The TX starting time is not exactly sure but perhaps arround 14 UTC. Hopefully one can see something on the DF6NM's VLF grabber.

Bernd/DF8ZR will be QRV in abt 16km Distance. 

Marco/DD7PC, will you be QRV in the evening? Our QRB is 53km, that would be a moderate distance ;-)

Bernd told me that many stns have become QRV in the last weeks in the local region. They will be informed by him and maybe they produce some nice screenshots.

Maybe i do not reach the full planned 20kV rms but it will be more than the 1,6kV from the last test ;-)

So, hpe to report something new from the VLF front next :-)

vy 73, Stefan/DK7FC
