I just purchased a TYT ThUV3R with the idea of using it for 220. It seems that the only way to activate the 220MHZ functions is to program it using the manufactures software. I down loaded verion 3.2.0.0 of the prolific driver and the manufactures software but when I try to access the radio, I will see the RW--COM displayed on the radio and I get a message the tells me to check the cables. However, I can program the radio using the latest daily CHIRP software without any problem, but it will not program the 220MHZ range. I realize this is the chirp group but I'm hoping someone can give me a suggestion as to how to make this all work.
