Drone Voice Radio
ETR20UAA
The airborne voice radio uses advanced software radio (SDR) technology to achieve AM voice communication between the UAV ground control station and the air traffic control tower or other manned platforms through the UAV control link. This voice radio uses the most advanced AI intelligent noise reduction filtering technology, which can achieve good voice reception under low signal-to-noise ratio conditions.
