I spent a lot of time working on digital mode configurations with my KX2 this weekend. I got involved in a thread on the Elecraft mailing list regarding FT8 configuration using a SignaLink USB. Even though I had a functioning configuration using a USB soundcard I pulled out my SignaLink USB, the jumper board, and cables in order to put that configuration together for use with my KX2 as well. I got it going for both WSJT-X and Fldigi. One thing led to another and as I was putting together a little document with notes for myself I decided to polish it up a bit and post it.
Here it is:

Understand that there are more than a couple of variables involved in setting this up. Your situation and\or needs may well differ from mine. It’s not an exhaustive document, there are other bits for you to sort out, but it may be useful to get you started. As I said, I was preparing a simple document for myself to keep track of my configurations and it sort of took on a life of its own. I’m early into my experience with these modes and the KX2. Also, I only have a KX2 with which to test but I’m pretty sure that all of this works the same for a KX3. If you find this useful, great. If not, so be it. As they say, YMMV.
Ps – If you find any errors please let me know and I will correct them and re-post.
