[Elecraft] USB Sound Card for digital modes.

[Kenneth A. Christiansen]

Hi from Ken

I put Windows7 on my computer and for the most part everything is 
working well but now I got around to using PSK31 and have a problem. The 
waterfall will show a signal for just a couple of seconds but then the 
signal goes away. I thought I had it fixed by turning off the noise 
reduction feature in Windows7 but now as I try to use it I notice that 
the signal input drops off just as though there is an auto gain feature 
that holds the audio too low for the digital programs to work properly. 
I can increase the gain in either the computer or the K3 but after about 
2 seconds the gain drops off.

My question is what USB sound card works best and if I change to a USB 
sound card will it work the way the old Windows sound cards worked or 
will I still be up against the new AGC action.

Thanks in advance for any advice I get.
