<p class="MsoNormal"><span style="font-size:11.0pt">Don\u2019t know if this will help, but I had a similar issue when setting up FT8 using WSJX and my Yaesu. Turns out I needed to download and install a virtual serial port driver that makes the USB look like a
Com1 to the computer etc. Just google VCP drivers and select 1 appropriate for your machine and OS.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif;color:#1F497D">I had the same problem a month or two ago, although I was trying to get my new laptop to talk to my IC-7300 using WSJT-X for FT8 work. I spent may hours trying to get it to work,
watching YouTube videos, reading WSJT-X manual and IC-7300 manual, following AI instructions. Nothing worked until I used an old laptop I had kicking around. Now it works perfectly. Something about my new laptop it didn\u2019t like.<br>
