The generated noise is well above the noise of the soundcard+the noise of the antenna. And the noise of the soundcard+the noise of the antenna is well a; /rsgb_lf_group-archives/html/rsgb_lf_group/2010-11/msg00332.html (21,572 bytes)

Maybe he is right about the generator. I am wondering too, why the maximum gain is at 2 kHz.
