Beeneons  on Instagram: "A radio hobbyist built a homemade Yagi antenna and used an amateur (HAM) radio to talk directly to an astronaut on the International Space Station. By tracking the ISS orbit and tuning in at exactly the right moment as it flew overhead, he made contact during the short window when the station was in range. Licensed HAM radio operators can regularly speak with the ISS during scheduled passes, often for educational and experimental purposes. #space"
