I cannot agree with your recommendation of the Syba sound card. Clicking on the link you provided tells me that I purchased this from Amazon on February 18, 2017. It therefore lies in a box with all the other USB sound interfaces that I purchased and spent WAY too much time playing with to try and get working with my KX3.
Instead, I have the SignaLink USB along with the Elecraft KX3 personality module and interface cable, and once I got over my initial hesitation to use it (a hesitation borne of the comments of "everybody says it's an inferior sound card"; because of that, I was loath to put it in service) I find that it is a satisfactory solution; it doesn't have nearly the fiddle factor and instabilities that I faced with the other interfaces and it satisfies my needs admirably. So I guess the one phrase I can use is "Different strokes and all that" when it comes to interfaces. :) --- 72, Rich Hurd / WC3T / DMR: 3142737 PA Army MARS, Northampton County RACES, EPA-ARRL Public Information Officer for Scouting Latitude: 40.761621 Longitude: -75.288988 (40°45.68' N 75°17.33' W) Grid: *FN20is* On Mon, Sep 4, 2017 at 10:24 PM, Walter Underwood <wun...@wunderwood.org> wrote: > I cannot agree with the Signalink USB being inexpensive.
