Two hundred miles offshore a storm is still a hurricane and your phone still shows five bars. Eight hours later the feeders are down across three counties, the house is dark, and every call gets the same recording. The towers are standing. What failed is capacity: a cell site on battery or a generator serves a fraction of the traffic it serves on grid power, and when a whole county loses power at once every handset reaches for the same site.
That is the real communications problem in a blackout. Not an exotic attack — congestion, a phone at fourteen percent, and a family that never agreed on where to meet.
Voice calls go first. Text messages ride in small queued packets instead of needing a live connection, so they frequently slip through while calls will not. The FCC's emergency guidance is low-tech about the rest: charge phones before the storm, keep a car charger or power bank, write important numbers on paper, and make sure everyone in the house knows how to send a text.
Radio is where preparedness money goes wrong, because gear is sold on range claims printed on cardboard. The licence is what decides whether you can legally key up.
| Service | Licence | What it is for |
|---|---|---|
| FRS | None — licensed by rule | Handheld family traffic, line of sight |
| GMRS | FCC individual licence, ten-year term, covers immediate family | Handhelds and mobiles with real antennas, optional repeaters |
| CB / MURS | None | Vehicle to vehicle, short local traffic |
| Amateur | Technician exam, thirty-five questions | Local nets and regional traffic when other networks saturate |
GMRS is the sweet spot for most households: one licence, a ten-year term, immediate family covered, and detachable antennas on mobiles so the antenna can go on the roof or the truck. Amateur radio reaches further and is the service most likely to still have a live human on it when commercial networks jam, but you sit the exam first. Neither is a licence to transmit anywhere you like. Stay on the channels your service authorises, and if you are unsure, listen.
The FCC puts GMRS range at one mile to twenty-five depending on station class, terrain, and repeater use. That spread is the lesson. A handheld in a subdivision of brick and stucco will not do what the same radio does from a ridge. So test it: walk the neighbourhood, note where the signal dies, mark two high spots that work. That afternoon is worth more than the difference between two radios at the same price.
Every radio, phone, and optic in the kit is a battery with an antenna attached. Pick one cell format and stay with it — AA for cheap items, 18650 or a single proprietary pack for anything you depend on — then count runtime for how you actually use it. Watt-hours on a power bank divided by device draw is how many charges you really have, and the same arithmetic governs a generator or battery-station plan, which we worked through in backup power without the carbon monoxide risk. For evening work, our piece on lights that survive a blackout covers runtime and battery commonality in detail.
A NOAA Weather Radio is the only comms device in the house that does not care whether a network is healthy. The National Weather Service broadcasts continuously from more than a thousand transmitters on seven VHF frequencies, and a receiver with battery backup keeps working when the local cell site does not. Get one with SAME county coding so it wakes you for your county, keep batteries in it, and test it before storm season rather than during one.
Every family needs one out-of-town contact, because a long-distance route is often less congested than the local switch. Agree on two check-in windows a day, and on the rule that no news is good news — silence means the plan is working, not that someone is missing. Pick a rally point within walking distance and one outside the neighbourhood. Print the card: names, numbers, rally points, the out-of-town contact, where the medication and spare keys are. One copy per bag, one on the fridge, because the phone is what dies first.
A radio is not a broadcast licence for your pantry. Do not narrate your supplies, your generator, or your absence on the air or in a neighbourhood chat. Listening is free; share what you would tell a stranger at the fence, and nothing more.
None of this replaces judgement. If a firearm is part of your household plan it sits at the very back of the stack: behind lighting, locks, a plan the family knows, and neighbours who would notice a stranger. Store it so only the people who should reach it can, and keep the four rules absolute. The thinking behind a simple long gun for a dark house is in the home-defense long gun when the lights go out. If you are buying, use a dealer who will walk you through the paperwork — you can find an FFL dealer in Texas or in your own state. The radio, the battery, and the card are the parts that get used.
