How it works
A reliable, neighborhood-powered radio network that continues operating when traditional infrastructure fails.
No Cell Towers Needed
Radios communicate directly device-to-device on public, license-free radio frequencies. No internet connection, cellular contract, or subscription required.
Community Relays
Every node helps relay messages across the network. Packets hop from pocket radios to rooftops to span entire neighborhoods and coastal towns.
Built for Storm Resilience
Designed specifically for hurricane season and severe weather. Radios sip tiny amounts of power and keep running on small solar panels or portable USB power banks.
Get started at your own pace
Choose the setup that fits your needs — from a personal handheld carry to a rooftop solar repeater.
Pocket Radio
A handheld radio that connects to your smartphone via Bluetooth. Text off-grid and check in with family when cellular service is down.
Rooftop Repeater
A weather-resistant solar node installed on a roof, mast, or chimney to extend coverage and bridge your neighborhood to the wider net.
Base Station
A permanent station or server for your home or workshop, providing continuous monitoring and regional emergency bulletin broadcasts.
