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 ?
