Hello Stefan,

 

I still do not have a proper VLF= setup, sri.

But an hour ago I did a "qui= ck and dirty" test:

just connected the 500kHz antenna to= the mic in of the soundcard, using an old PC (pentium 400MHz) as I didn't= wanted to risk the good soundcard.  I did set the sample rate= to 22.1kHz and FFT bin to 524288. The resu!t was a clear trace on 8970Hz, so a positive id of your signal. An attemt to improve SN= R by increasing the FFT bin to 2097152 resulted in a PC crash. Most likely= due to insiffucient memory rather than the PC speed.

I know, after being copied in Isreal my report is not very spectacular,= but you can add another country to your "being heard" list= .
