Something I ran across discussing Meshtastic:

Discover the Benefits of Meshtastic for Ham Radio Operators

Ham radio operators have long relied on traditional radio communication to connect across distances, share information, and support emergency efforts. Yet, as technology evolves, new tools emerge that can enhance these capabilities. One such tool gaining attention is Meshtastic, an open-source, low-power, long-range communication system that works alongside ham radio setups. This post explores why ham radio enthusiasts should consider trying Meshtastic and how it can add value to their communication toolkit.

Meshtastic offers a fresh way to communicate when conventional networks are unavailable or unreliable. It uses inexpensive hardware and mesh networking to create a decentralized communication system. This means messages can hop between devices until they reach their destination, extending range and reliability without relying on cell towers or the internet.
