Yes, it is the G3RUH mod and there is a least one site that shows you in
pictures where to solder the wire as I remember. I did this about a year
ago when I was first testing the software. I get great decodes from the
FT-736R this way.
Use an old headphones cable with the earbuds cutoff as the wire. Then you
have a plug ready to connect to your soundcard! If you have a choice use
Line In rather than Mic on the computer.
