Re: LF: USB Sound Card?

Hi Warren,

Cheap devices for 3 EUR (or $) will do most jobs very well. But it may be worth to spend some more money. 192 kHz sampling rate is available for a low price.
But you may first try to install a new driver for the existing one. Look for the name of the mother board and search in google for driver packages. Maybe it helps.
Or install Teamviewer software and let someone of "us" check if something can be done if you are not sure that everything is set correctly but doesn't work anyway...
It is likely that the internal one runs at 96 kS/s or maybe even 192. And the internal ones are often a bit better than the USB cards.

I guess I should have been more specific .

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  for LF data modes?

 I wonder if anyone has tried 192kHz sample rate for direct reception of 73kHz?

I just acquired a Windows Vista tower computer - the price was right it was free!

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.
