Based on the radio issues, I absolutely believe he has a problem in that department as well but, would his car not start and run while jumped? If it's the battery it should start and run till he kills it. If it's the alternator it should start and run while still connected. If it's both he should get the same thing.
I'm not trying to argue I more just want to know why you think otherwise for my own knowledge.
