I've cycled through all 3 options and they do what they say. Every time you change it deletes things. At the end of the menu system, it opens up even more frequencies above gmrs, but every time you upload to it, you have to change those settings again. About to do a firmware update and see what that opens up. Nice little radio, it replaces my 1.2 meter, 2 meter, 70cm ham radios along with my FRS, MUCS, GMRS and Marine VHF radios as well...
