QO-100 Telemetry Data Reception with GNU Radio Companion 3.8.1
Reception of PSK data via a 1.3m offset satellite dish, a converted LNB that mixes down the reception frequency from about 10GHz to about 739MHz and an RTL stick on the PC. The data is then processed and decoded by the PC (Intel Core I7, Debian 10) and the software GNU Radio Companion.
