Hi Alberto,
You probable see in the picture Tavolara Italy which listed on 20.27 KHz. Most of the VLF stations use MSK modulation.

Hi all,
   I have just built a small indoor loop, and have connected
it to the sound card. No preamp, just a step-up transformer.
I see the signals visible in the attached picture. Is anybody
able to recognize them ?
Some of the signals seem to be spaced 100 Hz, but going
to higher resolution, the spacing is just a bit short of 100 Hz...
And the blurb at 20200 - 20300, is it an RTTY ?
