I went to update the programming on my kenwood THF6a using the kenwood programming cable + USB serial adapter. I tried both the Link 700 and the kenwood software. No matter what I do, it just won't read or update the radio anymore. It acts like it can't even talk to it. This was working fine, and I didn't change anything. I've tried checking the assigned serial ports, numerous settings, everything you can think of. The USB serial adapter works just fine with other equipment. I'm thinking it might be the kenwood cable, but i'm not sure how to test it to see? I've never seen a schematic for this cable. I'm about to try this on an XP machine to see what happens also. Oh yeah...one more thing...time for a brief rant....WTF is the deal with radio equipment manufacturers continuing to use serial interfaces?? Why can't they get with the program and use USB 2.0 intefaces like every other technology? I mean seriously...Serial has been dead for what, 10 years now? Good Grief!!!!
