OpenMesh Voice Network

 

OpenMesh Voice Network grew out of a simple observation: daily amateur radio life revolves around voice repeaters, yet those single points of failure require significant maintenance and professional resources. They often collapse when operators most need them—during storms, wildfires, and other disasters. Our team of volunteer hams and digital-comms researchers set out to remove that vulnerability by marrying low-cost software-defined radios with a modern, AI-powered voice codec. The result is a fully open-source mesh system that carries clear voice and lightweight data over battery-friendly VHF/UHF links. Hence, daily conversations and emergency traffic flow even when towers or internet backhauls go dark.

Traditional repeaters demand expensive sites and constant upkeep; whole communities fall silent when they fail. By contrast, a self-healing mesh of small nodes lets operators in remote villages, search-and-rescue teams, and emergency coordinators drop in coverage wherever it’s needed, with no cranes or leases required. Beyond crisis use, the same network keeps daily rag-chews, club nets, and technical round-tables alive, sustaining the social glue of amateur radio.

Our purpose

We exist to keep people connecting and talking—and to do it in a transparent, hackable, and welcoming way. By publishing every line of code, every trace on the board, and every lesson learned, we hope to spark a new wave of experimentation in digital voice, inspire classrooms and maker spaces, and give the global ham community a resilient, modern alternative to 20th-century repeaters.
