Easy as Pie!
I have the KPG 49D software. I use it to program my 2 TK-380 UHF radios. The programming is easier and / or simpler than most scanner software. Its pretty straight foward. The nice thing that the commercial software has, at least for Kenwood, is with multiple radios. Once you get the frequencies set the way you want them, you can hit send and it goes to the radio. NOW, without any other function being performed, you can unplug the radio and plug in another one or two and just keep hitting send without having to re-format each radio. Plug and send baby! If you have any problems or questions, PM me. I will be glad to help. The software will only work on windows XP, no Vista patches available as far as I know anyway. Good Luck!
