Hi Warren,

Yes, I had an internal (on main board) & used it for a while for my grabber when 73kHz was first allocated to USA.
It was good to about 94kHz.

The SB0490 I suggested is only 96kHz :-((

What I am seeking is are some sound cards more stable with respect to sampling rate and calibration? Also, any advantage to 24bit A/D =C2=A0for LF data modes?
=C2=A0I wonder if anyone has tried 192kHz sample rate for direct reception of 73kHz?

73 & Tnx Warren

Seems that there is a problem with the internal sound card, but everything else checks out FB.
I plan on using it with WSPR and other digital modes, am thinking of an external USB sound card - will any old sound card do ? Or do I need one with a calibrated sampling rate? I suspect that I will need something really good for Spectrum Laboratory if I want to sample at microHertz rates.
