You'll grow tired of the Butel software. There are several threads regarding the 4 available options. Icom, RT Systems, Butel, and direct spreadsheet CSV import/export.I'm wishing now I had gone with Butel. I have had really great success in the past with RT Systems on ham handhelds and mobile units but their R30 software is extremely slow and very buggy. I would not recommend it.
Good luck mate.
