VLF,
Ossi is coming trough to across the Alps in Italy! See Renato Romeros
spectrogram at http://www.vlf.it/cumiana/livedata.html (scroll down)
The signal appears at 8970.03 Hz at about 10 dB SNR in 3.8 mHz.
The distance is 576 km! See:
http://no.nonsense.ee/qthmap/?qth=JN68RB&from=JN34RW
It's a day of very low QRN today!
Maybe Renato can adjust the color scale to allow better readability?
What a day!
73, Stefan

Excellent, Ossi and Halldór, this is quite impressive! And on top of that,
it looks like the signal is appearing on Chris' grabber in Haifa now as
well.
Comparing signal levels on my grabber, Stefan was -68 dB yesterday morning,
and you are about -83 dB today. As Nuernberg is pretty much in the middle
between the two of you, this can be related to a 15 dB difference in ERP. On
an absolute scale, Stefan mentioned that he had 1.2 A into his 300 m kite
wire, giving a radiated power of 46 mW EMRP. Thus you are radiating about
1.5 mW EMRP today - quite a good signal.
Best 73
Markus
