Jim, I have tried CTWin 9.85.003 with my FT897 and so far it looks as if it works all fine. You have to select the FT847 in the setup menu of CT. I have use 4800 and 9600 baud rate connection via the original CT62 Yaesu interface cable. I just now tried it with version CTWin 9.87 and it works also OK. Regards, Gerben - PA5NT
