    A quick how to guide on getting setup with your Elecraft KX series radio and WSJT-X to take advantage of the super efficient JT modes developed by K1JT.

    Using a simple inexpensive USB sound card dongle as your interface, you can be up and running in no time!

    Stay tuned for more videos on the Elecraft KX3 from SignalSearch & K5ACL.net!

    Excellent Johnny. Thank you for posting this. I wonder if I can do the same with my kx2. I have the same little USB audio interface you show there. I'll have to check this out and see. I have not worked WSJT-X as yet. I will though, in time. Very simple to follow instructions. Appreciate you taking the time to create these videos.

    An inexpensive usb dangle will work on the KX2 just fine. I use one purchased during the Radio Shack liquidation with no problems encountered.

    Thank you for us dummies...:)

    At the risk of sounding REALLY dumb, can you be more specific about the dongle sound card? I am using Windows 10 with a Surface, for example. Lotsa lotsa choices on amazon--makes it a bit confusing for an old brain...

    Excellent video! Thanks! I do a lot of JT65 and other soundcard modes using Fldigi with my KX3 and you've done a fine job.

    However...I think you'd be better off using the KX3's Data A mode instead of Upper Sideband. According to the KX3 manual, when you select Data A, compression and RX/TX equalization are disabled. This is documented on Page 18 of the latest KX3 manual.

    What is the software you're running that shows JT65 contacts on the globe?

    That is MacLoggerDX from DogPark Software. I don't think it is showing just JT65 contacts. Rather, it is showing the DX cluster reports.

    Thanks! I do use a Mac at times and I have a copy of MacLoggerDX so I will have to take a look at that.

    Thanks for the video, I have downloaded the WSJT package and will be playing about with it soon. I already have WSPR and Winmor, which work well from my 8 inch Windows tablet. One thing that might be of interest to KX3 owners is the LP-Pan website:


    In the table of sound-cards, towards the bottom, is this usb soundcard:

    The advantage of the SYBA card is that it has stereo line in, whilst most other mini usb cards are only mono line in. That works fine for digi-modes, but if you have stereo line in you can also use the RX I/Q output on the KX3 for a pan-adapter or SDR radio program like HDSDR. As the table shows, it gives a very useful 92KHz of bandwidth. One thing to be aware of, is that very small low-spec tablets will not have sufficient usb resources to run at the full 24 bits; I find 16 bits works fine. The price is also very reasonable for both pan-adapter and digi-mode capabilities. Beware of sound-cards that look like the SYBA in every way but do not have stereo line in. No new information here, obviously, just re-sharing for those new to the exciting world of the KX3 ; )

    'it gives a very useful 92KHz of bandwidth'
    Sorry, I meant 96KHz.

    I have KX2 I tried to use with JT - yes it's working in similar way but radio is really getting hot even at 5W. A cooling solution would be welcome although finals are directly attached to the right side so not that easy like in KX3 when you put radiator on the top.
    So not using it often for that purpose. To get DX you need really efficient antenna and on clear/high - for SOTA like should be pretty perfect with a dipole for 20m.
