This is a beta release of the meshtastic.org project. We'd love you to try it and tell us what you think. You'll need to buy an inexpensive ($30ish) radio from a variety of vendors to use this application, see our website for details. We don't make these devices. ***Please*** if you have questions: post on our forum and we'll work together to fix them (we are volunteer hobbyists). This post is a good place to get started. We would really appreciate good Google reviews if you think this is a good project.
