I've been reading online about the TK880s (and 780s) and I see listings for ver. 2 radios, ver. 1, etc. Also when I lookup the programming software it shows KPG-49D and KPG-60D, I didn't know if the software changed between versions, or even what the versions mean, any help would be appreciated, I own TK 860G's (and a 760G) and I know the difference between the G models and not-G models and can program them no problem. The 780s and 880s seem very similar to the 760Gs/860Gs. Thanks
