WSJT-X FT8 and the Icom 7300 the Easy Way!

Are you looking for an easy way to try out the new WSJT-X FT8 mode? If you have the Icom 7300 I assure you this cannot get any easier or better. There’s no need for an external sound card (Signalink) or any other hardware. The Icom 7300 suffices. The only thing needed is a USB cable (install the driver from Icom before connecting a USB cable) and WSJT-X.

“WSJT-X implements communication protocols or “modes” called FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected from the Moon.Β  These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal conditions.” – WSJT Home Page

Stand Alone Preferred by Many

Over the past few weeks I have run across Hams who have been using WSJT-X just like this. No integration with any other programs. There is really no need for JTAlert, QSO Relay or any logbook. This is the preferred way to operate for many Hams.

Super Simple Installation

I’ll put the download link below. This is a safe, small and easy program to get running on your computer. Windows, Linux and Macintosh are supported. Go to the link below, click on it and download the file to your computer. From there it will vary, depending on computer OS, but in Windows just double-click the downloaded file and go through the installation prompts. It is super simple!


In WSJT-X there are just a few configuration settings to get the Icom 7300 on the air with FT8.

  • In the software, under File and Settings, on the General Tab enter your callsign and grid square.
  • On the Radio tab select the Icom 7300 for the Rig. You’ll need to know your COM port number.
  • On the Audio tab tell WSJT-X what your Soundcard Input and Output are. It’s going to be the Icom 7300 USB Audio CODEC for both.

The rest is in the video. There are just a few more things to look at and you’ll be on the air.

Here are screen shots from my Icom 7300.

WSJT-X The Easy Way!

In this video I cover the download locations for WSJT-X, how to run it and using the built in logging capability. Also included, additional settings, making a contact and finally importing WSJT-X log into HRD logbook.

Once you get it installed I have a few more videos on the Icom 7300 to improve reception, transmit and make the WSJT-X Wide Graph (waterfall) look its best. See below.

Thank you for stopping by and visiting my website. There will be more to come on the IC-7300 and IC-7610.

Have you been on FT8? What do you think about it?

  1. Thanks Rich. You ended several days of frustration trying to get my IC-7300 to transmit using PSK 31 and HRD. One stinking little setting was wrong in the 7300. Thanks for your efforts with the very informative videos.
    I was just ready to start setting up for FT8 when your latest video came out. Perfect timing.

    Have a merry Christmas and a happy and healthy new year.

    1. Rich,
      I so much enjoy the videos and learn a great deal when watching them.
      Re the Icom 7300 and the running of WSJTX software, I too have the problem with the
      with the “USB-D” jumping back to “USB” after transmission. The packet setting does not seem to make
      any change in correcting the fault for me.
      It faked me out for a while not transmitting and then I remembered your comment of the USB-DATA comment.
      Switching back manually sets it to one transmit then it goes and then back to usb.
      HELP !
      Happy New Year to you young man.

        Hi Jon,

        Just listening to your voice mail πŸ™‚ Long day here and -25f in Aberdeen, SD!

        I was using Rig for Split Operation and this can cause problems for some, as well as myself, so I am using “Fake it” for Split Operation. This works best.
        See if that does it for you Jon.

        File>Settings>Radio tab. Look underneath Split Operation and you’ll see “Fake it”. Use that.

        Nice to hear from you! See if that does it for you, let me know. HNY!

        Rich, K0PIR

  2. Very good
    Fixing to down load today and see what
    Happens. 1st attempt no audio. I’ll delete
    And start afresh.
    73 and all the best

  3. Hi Rich, tnx for the various informative videos on the 7300 and the one on FT8 and WSJT-X in particular. Triggered an interest in digital modes and got things quickly working without going through massive documentation. Which I’m now doing anyway one I’m really nterested πŸ™‚

    Happy New Year and best 73!

  4. When installing the driver, should I select bit version that matches the installed OS?

    1. Author

      Hi John,

      It’s nice to hear from you and that’s a great question because even some of our programs are 32bit when we have a 64bit OS.

      Yes choose the one that fits your system. I have a 64bit. In the Windows File Explorer if I right click on This PC and select Properties, it shows the system information.

      Thank you and best 73,

      Hi Alan,

      It’s nice to hear from you and thank you for commenting.

      Are you still seeing the waterfall and signals coming through? Verify you are on the correct freq. and mode. The radio is in USB-D mode too.

      It could be the time. Are you using something like Netime to sync your computer clock.


      Rich, K0PIR

  6. Hi Rich
    no i wasn’t using netime i have downloaded it and everything seems to be running ok now
    Thanks for your help and i enjoy the videos keep up the good work

  7. Hi Rich,

    Dan here…WA2BTR. I just got the Icom 7300 for Christmas so thank you for the excellent videos. You might have covered this, but when I plug the USB cable in I lose the computer audio. I am trying to follow along with your videos but can’t since the audio goes when I am connected! It’s probably a simple setting I am missing, but any help would be greatly appreciated! I do see the waterfall display on my computer screen by the way using N1MM Logger, but that’s as far as I have gotten.

    Thanks and 73,

      Hi Dan,

      When I was using Windows 7 and my Signalink USB I had the same problem.

      Now I’m using Windows 10 and of course the 7300 or the 7610 and it works great.

      In the computer for the Playback devices I have the computer speakers set as the default. Then of course in the Ham software, I am using the USB Audio CODEC for soundcard in and out.

      See if setting your computer speakers as the default Playback device works.

      Rich, K0PIR

  8. Thanks Rich…that did it! Hopefully this weekend I’ll get to play with it to see if I can actually get it rolling!

  9. Thanks for posting the screen shots of the IC-7300 data mode settings. I’d spent a few hours going back and forth between the IC-7300 and my laptop (running WSJT-X on Ubuntu Linux 16.04) trying to figure out why I could receive just fine but transmit was a no-go, I’d convinced myself It was a laptop setting, thanks to your screen shots it turned out that I’d missed a simple setting on the IC-7300. Very grateful, thanks!

      Hi Jason,

      Good to hear form you and I’m glad it was of some help. Thanks for leaving the comment.

      I haven’t tried it with Ubuntu, but I’ll bet it works good. The Raspberry Pi is a blast.

      73 and good DX!
