How Amateur Radio Fans Decoded SpaceX's Telemetry & Engineering Video
Over the weekend amateur radio tinkerers in Europe managed to decode some portions of the telemetry data broadcast by the second stage of the Falcon 9 when it's in orbit. This data was in a somewhat standard format, but decoding still required some custom tools to extract the bitstream from the signal and then some guesswork to figure out the exact format.
There's still lots of unknown data, but most interestingly this gave access to the engineering cameras including one showing the interior of the liquid oxygen tank.
