Howdy Wes, I may be reading something wrong, but it sounds to me like you don't need an external sound card - you need a faster computer with more RAM. Or you need to disconnect LP-PAN when you are using sound card intensive applications. The problem sounds to me like you are pushing the limits of your computer when you run LP-PAN, and adding an external sound card will further tax your computer. The answer I think may be to either reduce the current load by eliminating LP-PAN when you run RTTY, or replace the computer with more horsepower. Just my guess...GL and VY 73, Lance
