What is Meshtastic?
Meshtastic is an open source, off-grid, decentralized mesh network built to run on affordable, low-power devices. It can be used to send text messages, location information, and telemetry data between members of the mesh. Unlicensed users can operate on the ISM bands, but there is also a “licensed amateur radio” mode that can be used on the ham bands. SPARC operates a mesh on the 70cm amateur band.
More information can be found on the Meshtastic web site.

Where can I expect coverage?
Nodes are currently online in Leamington (VE3IRR, VA3BHV), Kingsville (VE3SQ), and Amherstburg (VE3BOK). SPARC also has a repeater (VE3SPR/1) on Mike Ciacelli’s tower north of Leamington.
Coverage will expand as more nodes are added. If you’re unable to reach the mesh from your location, it is possible to connect your node to the rest of the mesh via the internet. Contact Clayton (VE3IRR) if you would like to try this: argilo@gmail.com
