CQ CQ on 3 cm!

On May 24, 2017, two student groups at TU Wien set up two transceivers for X-band operation (10368-10370 MHz). See fotos below. The first task in the practical part of the course „Centimeter- and Millimeter Waves“ (LVA 389.190) is to integrate all components (YAESU FT-817ND, Kuhne 10 GHz Transverter, 57cm parabolic dish, WR90 feed horn, coaxial relays) into a working prototype. The first real-life test is the reception of the OE1XGA beacon located on Kahlenberg north of Vienna city. Second test was a bidirectional voice link in SSB modulation. Mission accomplished. Next tasks will be measurements on the antennas, link budget, diffraction effects of a plate, and oscillator stability,  … and comparing those with the predictions from theory.
