Communications When the Grid Goes Down

Have more than one way to hear and be heard. Charge everything before a storm.

1. A radio to hear
A battery or hand-crank AM/FM radio for official information. Know your local emergency stations.
2. Walkie-talkies to talk
FRS/GMRS radios for family within a few miles. Agree on a channel ahead of time.
3. A check-in plan
Pick a check-in time and an out-of-area contact everyone calls — local lines jam first. Keep messages short to save battery.
4. A whistle, no power needed
A whistle carries farther than your voice and costs no battery. Three blasts means help.

Common questions

What's the best way to communicate when the power is out?

Layer it: a hand-crank AM/FM radio to receive, FRS/GMRS walkie-talkies for family nearby, and a pre-agreed check-in time with an out-of-area contact. Keep a whistle for signaling.

Do walkie-talkies work when cell towers are down?

Yes — FRS/GMRS radios talk directly device-to-device and don't need cell towers, though range is limited to a few miles.
