Hi, I just wanted to endorse the "fix" that I gathered from the back and forth dialog on the issues board. I, too, found that I could download from the radio fine but it simply wouldn't upload. Seeing the OP got things to work with a new cable from BlueMax49ers.com I went ahead and ordered one although I could not see how the cable I used for years with other Yaesu radios did not work. Amazingly, the CT-91 BlueMax cable worked immediately and I just wanted to further endorse this "solution" to other FT-60 owners.
Another suggestion: There seems to be a missing line in the instruction drop down for uploading to the radio. There is no prompt to hit the OK as the final step as there is on the download instruction. You do have to hit the OK button or the download will not start.
Great program and great support. Thank you. Jerry
