Hello, so I've obtained Wouxun radio frequency unlock software which unlocks frequencies with the program. I have a question though. It says it works for the KG-819, so I have about 7 KG-819s UHF and I wanted to unlock them to receive VHF, from 136-174, but it doesnt work, it writes fine but then when I try to write the radio with the programming software it says "Channel message # out of range" and wont let me write. the "#" is whatever channel you try to write it to. Any help?
