Disclosure: We are not an Amazon Associate or an Etsy affiliate. Links go to third-party retailers as ordinary product links and earn us nothing. We chose these picks from our catalog without looking at commission, and we have not tested or rated them — what follows is what the listings state and what public guidance says. Prices and availability are set by the retailer. Full disclosure.

Again, an honest note about our shelf: the catalog has no Amazon listings for communications yet. The Etsy listings here are small sellers, mostly assembled radios, and a couple of picks come from other retailers and are labeled as such.

Layer One: Hear the Official Word

This layer is free or cheap. Wireless Emergency Alerts are pushed to compatible phones by government agencies. NOAA Weather Radio All Hazards is broadcast by the National Weather Service, and a receiver works without the internet. See the National Weather Service page and Ready.gov/alerts. Our guide on alerts that actually reach you covers signing up.

Layer Two: Talk to Your Street

Phones depend on towers and power, which both fail. Short-range radio does not. The choices differ in what the law asks of you:

• FRS handhelds are licence-free and low power.
• GMRS needs an FCC license that covers a household, with no exam.
• Amateur (ham) radio needs a license you earn by exam; see ARRL and the FCC. It is the most capable option and the most work.
• Meshtastic is an open-source system that uses low-power LoRa radios to relay short text messages between nodes. In the United States it uses the 915 MHz band, which does not require a user license. It is for text, not voice, and range depends heavily on terrain and antenna height.

Check current FCC rules yourself before you transmit; we summarize, we do not give legal advice.

The Picks

• RAKwireless WisBlock Meshtastic Starter Kit (US915) (Rokland) — the listing states the US915 band. A starting kit for the do-it-yourself route.
• Spec5 Ranger Meshtastic LoRa Radio with Keyboard (Etsy) — an assembled handheld with a keyboard so you can type without a phone. Ask the seller about the band, the firmware version and returns.
• ATAK Enabled S5 Trekker BRAVO Meshtastic LoRa Radio (Etsy) — a handheld for the same job; compare it with the one above on what it includes and what it costs.
• Meshtastic Solar Radio Node (Etsy) — a fixed node meant to sit outdoors and relay messages. A node on a high point is what extends your street's reach, but check where you can legally and safely mount it.
• LILYGO T-Echo Meshtastic LoRa Handheld (LILYGO) — the listing says 915 MHz, e-ink display and GPS.

The Part the Hardware Can't Do

A mesh with one node is a paperweight. The value is in a handful of neighbors who agree on a channel, a check-in time and who has a spare battery. Buy two, not one, and plan with the three or four households closest to you. The test is simple: can you send a message across your block with the Wi-Fi off? Try it on a sunny Saturday, not during the crisis.

The idea behind this layer is in when cell towers fail, and the assessment shows how you score on communication.
