I am new to amateur radio and have a new Beofeng UV-82.  I have gone through all the usual cable problems and managed to make communication with the radio.  My problem is that when I make changes to Chirp it will not save them either to the radio or to file.  I reverts to some default setting changing all new entries except the freq.  I am editing the entries by selecting the line then right clicking to enter the edit mode    This is very aggravating!   Help!
