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

[k3ndm at comcast.net]

David, 

I've been using the external USB Steinberg UR22. It's 192KHz sample rate at 24 bits. It's listed as have a 120 db SNR. It's ASIO compliant and cost is around $130 from Sweetwater. I don't know if Linux supports this card or not.

Hi, 

Splitting off from the Signalink thread, since it's actually a different 
question, what are the current external sound cards that people suggest 
(that are supported in Linux if known - if not - that's ok)? 

I see the Tascam mentioned in the PDF in the other thread, so I'm looking 
into those (the ones that support 192kHz now, that is) - are there any 
other suggestions to look into? I operate on a lot of digital modes, but my 
Lenovo Thinkpad T400's built in sound card adds a lot of noise to the 
signal I'm receiving. I have a Native Instruments Audio Kontrol 1 which 
works much better, but it is USB powered (it seemed to be indicated this 
was a no-no for best decoding in digital modes in the other thread). 

There are a lot of options out there now, so it's hard to sift through them 
all, and make a guess as to which are best for HF radio digital 
communication, so I thought a thread would be helpful in getting some ideas 
on what is tested/true. If Linux support is unknown, that's ok - I can do 
that research - but it would be great to have a list to start looking at 
that are known good performers with low noise. 

Thanks!
