EmergencyHam Network (EHN) is a unified communication system that connects people, devices, and services across radio, mesh, SMS, and internet networks.
It routes messages by identity, not device, automatically selecting the best available path.
When infrastructure is available, systems synchronize over the internet.
When it’s not, EHN continues to operate using RF and local networks, with built-in store-and-forward and recovery.
EHN is designed to bridge traditional amateur radio with modern IoT and digital systems—creating a resilient, flexible network that supports emergency response, community coordination, and everyday experimentation.
One Network. Any Transport. Always Operational.

EmergencyHam Network: Our First Working Alpha Is Ready for Testing
Connecting MeshCore, Meshtastic and SMS messaging — and inviting amateur radio clubs to help build the next generation of community communications. For some time, the EmergencyHam Network (EHN) has been developing a simple but ambitious idea: what if we could bring different communications technologies together into a single messaging system, allowing people to communicate without

Introducing the EHN Directory: Connecting People, Roles, and Devices Across Networks
When we talk about building a resilient, off-grid communication system, most people immediately think about radios, mesh networks, or long-distance links. But there’s a deeper question: How does the system actually know who a message is for—and how to reach them? That’s where the EHN Directory comes in. The Problem: Messages Without Meaningful Destinations In
FOR HAM RADIO OPERATORS
Join the Next Generation of Emergency Communications
We need 50 committed operators to achieve FCC experimental licensing and build a viable network.
Are you a licensed amateur radio operator who believes ham radio should evolve beyond voice contacts and digital modes? We’re building a monitored relay network that bridges amateur radio with modern IoT and messaging systems—creating resilient, internet-independent emergency communications when disasters strike.
FOR IoT DEVELOPERS / MAKERS / TECH ENTHUSIASTS
Build IoT That Works When the Internet Doesn’t
We need 50 participants to launch the experimental network and pursue FCC licensing.
What happens to your smart sensors, environmental monitors, and emergency alert systems when cellular networks fail and internet goes down? We’re creating a license-free emergency backup network using ham radio infrastructure.
FOR STEM EDUCATORS / MAKERSPACES / STUDENT CLUBS
Teach Emergency Communications That Actually Matters
We’re seeking 10-15 educational partnerships to launch student innovation challenges.
Your students learn coding, robotics, and electronics—but do they understand resilient communications when infrastructure fails? Partner with EmergencyHam.net to give students hands-on experience building disaster-ready sensor networks.
Critical Mass Goal: 50 Members by August 2026.
We attempted this vision five years ago and fell short. But the need has never been greater—wildfires, hurricanes, grid failures, and cyberattacks prove that internet-dependent communications aren’t enough.
This time, we’re not starting until we have commitment from 50 participants.
