I have done this many times with my IC7000 by following the manual for the Signal Link USB and manual for WSJT-X.? First of all, I purchased the IC-7000/FT-817 jumper module SLMMOD6PM for the Signal Link and installed that first thing. This module sets the correct rig jumpers in the 6-pin mini-DIN Data Port. If you don't have the module, you have to place jumpers properly as shown in the manual. You have to open the Signal Link to access this Port.? Then I simply followed the manuals. I set my power to 50W before operating. I use HRD for logging and find that WSJT-X plays well with HRD. There is a selection for IC-7000 in both. I'm sure setting for an IC-7300 won't work with an IC-7000.??
The relevant manuals are all available on-line.? The instructions to do all this can be found there. I've operated portable with my IC-7000 using PSK then later, FT-8 many many times with this setup.?
