High Performance Open Source Radio Control Link
Meshtastic™ is a project that lets you use inexpensive ($30 ish) GPS radios as an extensible, long battery life, secure, mesh GPS communicator. These radios are great for hiking, skiing, paragliding - essentially any hobby where you don’t have reliable internet access. Each member of your private mesh can always see the location and distance of all other members and any text messages sent to your group chat.
The radios automatically create a mesh to forward packets as needed, so everyone in the group can receive messages from even the furthest member. The radios will optionally work with your phone, but no phone is required.
Note: Questions after reading this? See our new forum.
Uses
- Outdoor sports where cellular coverage is limited. (Hiking, Skiing, Boating, Paragliding, Gliders etc..)
- Applications where closed source GPS communicators just won’t cut it (it is easy to add features for glider pilots etc…)
- Secure long-range communication within groups without depending on cellular providers
- Finding your lost kids ;-)
- Through our python API use these inexpensive radios to easily add mesh networking to your own projects.
Amid all the conversation about Signal, and the debate over decentralization, one thing has often not been raised: all of these things require an Internet connection.
“Of course,” you might say. “Internet is everywhere these days.” Well, not so much, and it turns out there are some very good reasons that people might want messengers that work offline. Here are some examples:
- Internet-using messengers leak certain metadata (eg, that a person is using it, or perhaps a sophisticated adversary could use timing analysis to determine that two people are talking using it)
- Cell signal outages due to natural disaster, large influx of people (protests, unusual sporting events, festivals, etc), or other factors
- Locations where cell signals are not available (rural areas, camping locations, wilderness areas, etc.)
- Devices that don’t have cell data capability (many tablets, phones that have had service expire, etc.)
FMLIST ist die weltweite Senderdatenbank des UKW/TV-Arbeitskreises e.V. Sie enthält technische Daten von Hörfunk- (FM, DAB) und Fernsehsendern (TV) im VHF- und UHF-Frequenzbereich. FMLIST hilft FM-DXern bei der Identifizierung von Sendern, und beim Führen von Logbüchern und Bandscans. FMLIST ist ein offenes Projekt und lebt von der Mitarbeit vieler einzelner Personen. Bitte unterstützen auch Sie dieses Projekt mit Informationen und Daten!
