Icom IC-9700 and WSJT-X
Below are the settings I use:
On WSJT :
On the ICOM 9700 (Only showing the non-default settings)
MENU -> SET -> Connectors -> MOD Input -> DATA MOD USB
All the rest I have factory default. If you want to use higher baudrate then you need to change this on WSJT and IC-9700. I would start with 9600 and get it to work and then adjust.
