QO-100 Telemetrie-Daten-Empfang mit GNU Radio Companion 3.8.1
Empfang der PSK-Daten über eine 1,3m-Offset-Satelliten-Schüssel, ein umgebautes LNB, das die Empfangsfrequenz von ca. 10GHz heruntermischt auf ca. 739MHz und einen RTL-Stick am PC. Die Daten werden dann vom PC (Intel Core I7, Debian 10) und der Software GNU Radio Companion aufbereitet und dekodiert.
Von QO-100 empfangene Nachrichten in der PSK-Bake, von Gnu Radio decodiert (Ausgabe der Console von GNU Radio Companion, Dank an DF1DO)
