This worked for me too. An added tip is one I got from Wayne when experiencing RF feedback on PSK31: Seat the two KIO3 rear panel connector boards (3.5mm fems, and also the RCA / 1/4" phono) so that there is a slight amount of interference with the screw-on panel. This allows the grounds for the jacks to make best contact with the 3.5mm plugs. It takes a little jiggling to get the fit to come out just right, but you need the jack bodies (sleeve is ground) to jut out just a little bit to get proper contact.
