[Elecraft] USB Sound Card

[Terry Posey]

I use an Asus XONAR U7 with NAP3 and CW Skimmer on a Lenovo Windows 10.x machine , attached to the K3 IF via LP-PAN2.  Almost all USB sound cards are quirky to set-up with your particular computer and your particular audio applications.   As for the "stuck" 48k sample rate:  make sure the little switch under the XONAR U7 is in the USB Audio 2.0 position, then follow the guidance for loading the correct driver - do not let Windows load the default driver.

I hope this helps.

Tom,

If the problem is only happening when the Asus U7 is the default soundcard, then how do you deal with the tendency of the Windows operating system to set any newly installed soundcard as the default?  
Seems like a "catch 22" to me.
Yes, the specs on the Asus U7 are very good, but for panadapter use, it needs the 192 kHz bandwidth.
