Nice,,,Everyone can du this with only your pc soundcard...connect a long wire to line or mic input and run a FFT program like the Italian Spectran program....very fun...LA3EQ Jan

Hi,

But how can you control/see the frequency ? Or doesn the audio frequency equals the station frequency ?

[cutterschoicenotmine]

@merasanam no

[ballm0use]

koss får du informasjon fra dataen? (dvs tale, tall)

[merasanam]

Is there any software that can decode the incoming data?

I wish my area (eastern USA) used VLF more, There is only 3 stations at 24 kHz and below. If you are somewhere where there is very good VLF reception and you don't have a computer, but you have a Linear PCM recorder like the Sony ICD-SX700, you can record in Linear PCM mode and analyze the signal later. I found a station at 21.3 kHz and a really weak one about 200 cycles higher. Of course, just touching the phone plug to my 96kHz laptop sound card with my finger picks up 24kHz.
