Giving advice on emergency preparation can be confusing because different degrees of emergency require different measures. If we’re talking about something like the Loma Prieta earthquake in the Bay Area that knocked out phones and the power grid for about a day, two meter ham radio came in handy to keep in touch with friends and family members who also had two meter radios and who were local. To communicate with friends and family outside of the Bay Area, battery powered HF ham radio was needed. If you experience a disaster that knocks out the phones for a day or two in your community, you’ll feel fortunate to be equipped with two meter ham radios. If the disaster knocks out power and communications with a 100 mile radius or greater, you’ll wish you had a HF radio station as well as two meters. To repeat, equipping yourself with two meter radios isn’t expensive and getting the license isn’t terribly difficult. It’s a good, reasonable measure to consider for emergency preparation. To go beyond two meters and set up an off-grid HF station will increase your range of communication but I’m not sure it’s worth the time, expense, and effort unless you also want to adopt ham radio as a hobby. I have two meter radios and a solar powered HF station but I also have a Garmin inReach Mini that can send and receive texts and email via satellite. I’m not sure how satellite communication will function during a wide area catastrophe, but I have it just in case. The monthly fee is about $12, which stings a little, but satellite communication is more reliable than ham radio and it would be convenient to communicate directly with friends and family outside of the catastrophe zone who don’t have radios.
