Hello, I am trying bto program a Baofeng UV5R radio using chirp software but set something wrong in the settings, when I power the radio up I cannot switch between frequency and channel mode and do not have anything when I hit the menu button to be able to go through the different menus on t5he radio itself. Does anyonyone know what the default settings are for the radio, or if its possible to reset to default settings with chirp so I can strart from scratch? Any help would be hugley appreciated. Thanks, tpone234
