I ran into the same thing a week ago - sent Dan the error log - maybe my email got caught in spam filter.
Sorry, it's still in my queue. I'm out of town this week and am struggling to keep up with everything.
I have a 1529 cable. It works fine with the CS-2820 software, but does not clone the radio from Chirp. I am using a serial to usb changer, but it's worked with all my other radios (Yaesu VX's, K2, IC 746, etc). Yes, I do have the correct com port selected. Any suggestions?
The 1529 is the data cable, right? I'm able to clone my 2820 that way. Perhaps you have GPS enabled? I haven't tried to clone through the data port with GPS turned on, but I always have mine off for D-RATS anyway.
If this isn't the problem, I'll definitely look at the debug log when I come up for air.
Thanks!
