Post for: #radio ^{(1 Post)}

Meshtastic is an open-source project that facilitates encrypted off-grid text communication between individuals and groups using low-cost radios. 

I've played with it intermittently for a few years but recently have gotten more involved. Thanks to talented devs and a passionate user-base, the community has grown significantly and the project matured.

I think it's a great way to learn about radio technologies, open-source projects and deploy a fairly inexpensive backup communication system across communities.
