I recently acquired a brand-new TYT UVF10. I downloaded the software for it and got the programming cable, which didn't come with the radio. However, when I tried to read it with the software, it gave me an error stating that it could not open the port. I tried this several times, each time getting the same error message. So, I decided to try it using a different computer. Same message. I can't seem to get the software to read the radio no matter what I do. Any ideas?
