KX2 Digital modes configuration examples

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.

  1. Tim,
    Just stumbled across this guide while looking for other things. I’ve been using my KX3 for digital modes since I first put it together in 2015. I’ve always used the external USB soundcard method using the accessory cable kit for the KX series.

    The setup is as easy as you have it there, and have never had a problem with any issues of ‘ground loops’, and really no need to use a Signallink with its issues of having to reset jumpers for different rigs.

    In fact my IC-718 uses the same soundcard, all I do is switch the audio in and out cables to the IC-718 interface cables.

    Great setup guide!!

    I am waiting on delivery of my KX2 and just happened across this site. I just checked your slides and I am both impressed and gratified that you took the time to put this together. Thanks for sharing, this will help me get the KX2 on the air and doing digital quick. Now to look for more KX2 info on the web.



    Got the KX2 a couple of days ago, made 1 contact via voice so all is good, the seller forgot to pack the KXUSB cable so waiting on that to arrive so I can do CAT control, I can receive WSJT-X (FT8) just fine on my laptop- just need the cable to do CAT…

  4. Thanks Tim. Very simple and no nonsense. Really appreciate your effort.
