Hi All, I have successfully worked FSK-RTTY in the past running my RigExpert Plus and Vista, I am now back home in Scotland and running XP Professional, all is well apart from being unable to configure the FSK port (number 20 in my case). I am constantly reminded that the port is either in use by another program, or does not exist at all. When I go to the "Device Manager" and try to link via another port, I am told that they are all either in use or do not exist. Is this a typical XP issue. Cheers, John - GM6TVR
