I add to my GNU radio receiver the PSK CRC beacon decoder.
The CRC beacon decoder was add just for fun and to refresh my digital communication skill after 28 years from Master degree and engineering career in completely different area.
All the decoder (viterbi,syncronization,de-scrambler) is write in python.
Antenna 40Cm dish with PLL lnb,SDR dongle locked on upper beacon
