I just bought a Chatterbox set-up, the GMRS version. I was wondering if anyone knows of a way to mod the radio to open up more frequencies? Any Hams in here will know exactly what I'm talking about. I would like to be able to talk to other folks and most folks seem to have the FRS versions. Also would like to be able to talk with people in cars if I am travelling with them, once again,, most people have the cheaper FRS radios.
