Hey, so My friends and I are building out a Meshtastic network with a bunch of cheap nodes built out of LoRa dev boards, solar panels, 18650 batteries, and Walmart plastic boxes. They don't have the best antennae or the best chips, but you can build them for about $20 each, and scatter them *everywhere* (with permission, of course).
I had a thought about using this mesh, or one like it, to link GMRS repeaters to get around the hills and mountains we deal with here. The data rates theoretically top out at about 5kbps, but that should be fine for raggedy old HT voice communications, and data is, well, data...
Anyone given any thought (or practice) to building a LoRa/GMRS modem?
