I just saw a great movie except for the ending (I confess most people thought the movie sucked) on Netflix called "How it Ends" and one thing I don't have is a Short Wave Radio with NOAA which was mentioned in the movie. Is this item a must to have especially if I would be leaving my home? It's hard to fit anything else in my Bug Out Backpack. Your thoughts and any that you'd recommend. Note I do have an AM/FM radio and a digital compact TV that is the size of the old Cassio ones.
