[RTTY] Product Review: Computer Sound Cards for Amateur Radio

[Jim Reisert AD1C]

There is a product review in May 2007 QST, "Computer Sound Cards for Amateur
Radio".  ARRL members can read the article at:

Bottom Line

"There are clear performance differences between inexpensive 16-bit sound cards
and the more expensive 24-bit models. For most digital mode users, any of these
cards will perform well. Software defined radios and other high-performance
applications will benefit from a high-end card."

Conclusions

"Most Amateur Radio sound card applications should work perfectly well with the
lower-end models. The 24-bit devices do have better specs, but very few
digital-mode apps are designed to take advantage of the higher precision. On
the other hand, critical applications such as software-defined radios can
definitely benefit from the superior noise, dynamic range, and distortion
characteristics of the high-performance cards."

If you can, I suggest you read the section, "A Real-World Test".
