Sorry to revive an old forum thread but has anyone had luck using sdrs like the hackrf and the software package satdump for receiving goes grb images. I just got a 8ft dish and built up a feed for it (dual monopole cantenna feed with hybrid coupler) but haven't been able to get any useful data via satdump. My snr is around 7 to 8dB which I think is on par for an 8ft dish (maybe even a little low).
Additionally has there been any more development/ testing with the tbs6903x that shows it is usable now for grb reception?
