Buzz writes informing us of a new open-source radio modem recently introduced by RFDesign known as the RFD900. “It’s initial focus is telemetry for UAV’s and FPV, but it’s an amazing piece of kit, with a whopping 1 Watt power, massive range of 40km, and it’s only $89.50 per unit. (Similar closed-source units sell for $250 and upward).” Buzz reports personally using this modem with positive results.
The modem covers the 902-928 ISM band and is designed for long range serial comms. The source code for this device is available on GitHub.
