Hi Susan,
I downloaded 0.1.9 and fired it up OK. Without connecting a radio, I selected the 'Convert ICF' function and selected an ICF file that I had downloaded from the Internet (actually "IC92AD_VK3RWN_C_V19a.icf" which David VK3UR makes available through the Australian D-Star web site - Thanks David) and tried to save it as an img file.
Unfortunately, the 9x radios' ICF files are not images of the radio memory like the others. This is because they are accessed with "rig control" commands instead of cloning the entire radio in one go. The 9x ICF format can be decoded, of course (and perhaps someone has done it elsewhere), and added to CHIRP at some point. I guess I really need to put an (or fix the) error message in there warning you when that fails so it's more clear what is going on.
I believe Stuart was planning to look into the 9x ICF format and implement the appropriate import logic to support it, but I'm not sure if there has been any progress made on that front.
