This is a very important component in survival 101 If the whole world goes sideways and phones can't be used what will you use to communicate? To get news? Before cable TV, folks listened to the radio. Do you have a way to get the news that doesn't require a computer, then Internet, a TV, cable, digital tuner? That fancy digital stereo will it work without power?
Use this section of your notebook to list all your radios, capabilities, CB radios, Consider getting a HAM license or joining a HAM club. You need a reliable way to get news and updates. You need a way to connect with others.
I suggest a couple of FRS or MURs handheld radio. List what you have, what you need and the time frame and budget to get it.
