MeshCom vs Locator DX

MeshCom is a project to exchange text messages via LORA radio modules. The primary goal is to realize networked off-grid messaging with low power and low cost hardware. The technical approach is based on the use of LORA radio modules which transmit messages, positions, measured values, telecontrol and much more with low transmission power over long distances. MeshCom modules can be combined to form a mesh network, but can also be connected to a message network via MeshCom gateways, which are ideally connected via HAMNET. This enables MeshCom radio networks, which are not connected to each other via radio, to communicate with each other.
