Which Com Port do I use I am thinking 3 but even that is not good. I have
attached a snip of Device Manager Coms and also the FT8 settings as I have
them.

I'm assuming you're using Windows.

RIght click the Start menu
Select Device Manager
Select Ports
Write down what those port numbers are. The port number you want must be
identified there.
GO back into WSJT and use that comport. You may have to juggle the baud
rate to get it to work.
