I have a .img file from a radio that has one of the settings bytes out-of-range. This causes the settings menus to not show up.

The exposed setting is already set to only use bit 1 and bit 0 but this allows 4 values, 0, 1, 2 and 3 but the setting only has 3 choices, 0, 1 and 2.

The radio came from the factory with the byte set to 0xFF. This causes the value to be 3 which is out-of-range.

           u8 unknown_flag_17:6,
             ponmsg:2;

        options = ["Off", "Welcome", "V bat"]
        rs = RadioSetting("ponmsg", "Poweron message",
                          RadioSettingValueList(options,
                                        options[self._memobj.settings.ponmsg]))
        top.append(rs)

How do I get CHIRP to ignore the out-of-range value or change it to a valid one?

Thanks,
Jim
