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

[Don Wilhelm]

David,

A regular 16 bit soundcard will do well when being used for digital 
modes.  Yes, the better soundcards have a lower noise floor which can 
help, but great bandwidth and bit rates are not required for those 
applications.
OTOH, if you are looking at panadapter applications, a good soundcard is 
important to get 192 kHz span width with low noise, and you sill want to 
use it at the higher bit rates unless you are satisfied with a 96 kHz span.

Select your needs and then select the soundcard that will fulfill those 
needs.  Even the lowly 16 bit cards are adequate for data mode applications.

73,
