Doh! I'm embarrassed. It's been long enough since I used the IC-9100 here that I missed the fact that it DOES have a bi-directional USB port for rig control and audio. I apologise if I sent you on a wild goose chase. K3DCW is, of course, quite correct. 73 de wb0ksl, John
I just tried installing WSJT-X on an iMax running OS 10.13.6 and got a fatal shared memory error. How do I get around this fatal error? 73 Carl WA0CQG
That is normal until you increase the shared memory buffer. Instructions for doing so are distributed with the installer- I don't remember it offhand.
With in the downloaded folder is a ReadMe file. Read this carefully and follow the instructions given there.
