Abstract: This paper presents an experiment on long-range command-and-telemetry link in 169 MHz band with engine-powered fixed-wing unmanned aerial vehicle (UAV), assuming to apply to the wide observation of coastal areas, where mobile phones are hardly available. In the experiment, we confirmed a direct link from ground station to the UAV with the distance of about 10 km. However, we also found a problem to overcome, which is on the onboard noise.
