I just bought the KPG-49D software. This works almost like CHIRP. The only problem I had was finding the setup files, which are not exe files. When I went to read the 880, I first had to select my COM port, which for me was port 5. After that it was straight forward with programming. I’m a member of NGGMRS network, and my 880 had some Freqs programmed in. I changed the names from ie, ATL-600 to the repeater name only. I also programmed in the normal GMRS channels, 1-7, 15-22. I drive from NE Georgia to Montgomery, AL every 3rd week, so I plan to program ABCD with the 4 repeaters in our linked network that I use on my trip. I have heard that I can program a DTMF mic to change channels, plus have the ABCD buttons mimic the radios ABCD.
