[Elecraft] Suggestions for good 192kHz external sound card fordigital modes

[David Orman]

KX3 == SDR == able to display large chunk of spectrum at a time. A 44kHz
card significantly limits this. My PX3 does 200kHz well. fldigi with some
source code edits can too.

Thank you for all of the responses, I'm reading up on every suggestion (and
site linked).

Thanks!
David
