I have a RigExpert TI-8 and Cable for the K3S that I bought new that does FSK with a built in Winkeyer as well. I thought I would use it on the K3S but instead I just went the USB route and do AFSK. It's still setting in the box looking lonely. I also have cables for the Ten Tec Orion II, and Kenwood 590SG which I have parted with recently and probably need to get rid of this much needed (Ya Right) stuff. Hi..
The USB route was the simplest and does all of the sound card modes. Ed..
