Well done, and congrats to everyone involved in the 8.97 kHz test !
The spectral spreading in Stefan's signal looks similar in Todmorden and Nuremberg, maybe the TX has been turned on and off with a few times with incoherent phase ?

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

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.
