Hi.. I'm hoping someone can help me out with the Radioddity version 2.0.2 programming software for the DB20-G mobile radio. I'm assuming its basically the same software for the Anytone listed on here. The DB20-G is setup for 400-490mhz and 136-174mhz, as is the program. My problem is that I cant highlight the CH option on the left side of menu. The other options open up a popup menu. Also, I can enter a gmrs freq in ch.1 but will not let me add a tone.. Not sure if I am missing something?? Thanks... Kevin
