A short video showing the radio and software (WSJT-X) settings necessary to operate FT-8 on the Icom IC-7300.
In this video I am using WSJTX version 1.8.0 running on Linux Mint 18.3 KDE.
Note: A separate Icom CI-V cable is not necessary to operate digital modes with the 7300, nor do you need a sound card interface such as a Signalink. The USB cable alone is adequate.
Here is a link to the USB cable I am using to connect the radio to the computer:
