GhostNet Version 1.5
By s2underground
“GhostNet is the overarching term for a collection of communications networks set up to allow users around the world to exchange information without relying on pre-established infrastructure. Far from being just an emergency plan, GhostNet is intended to ease the transition of radio technology into everyday life. Though radio networks cannot truly replace the internet, we hope that we can replace a substantial portion of a person’s daily information requirements, and promote a culture of off-grid information sharing.”

• Meet your local ham community
• See real-world radio in action (HF, VHF/UHF, digital, satellite)
• Learn about mesh networking (like AREDN, reticulum or meshtastic) and how to build your own resilient network
• Explore digital modes, SDR, antennas, off-grid power, and more
• Get on the air—no license needed at GOTA (Get On The Air) stations!
🛠 Whether you’re into disaster resilience, open-source comms, or just want to build cool stuff, Field Day is your signal to jump in.
