Since the hardware and software haven\u2019t changed on his side, the only logical conclusion is that SpaceX wasn\u2019t too happy about radio amateurs listening in on their rocket and decided to employ some form of encryption.<\/p>\n<p>Since this data has apparently been broadcast out in the clear for nearly a decade before anyone on the ground noticed, it\u2019s easy to see this as an overreaction. After all, what\u2019s the harm in a few geeks with hacked together antennas getting a peek at a stack of Starlink satellites? [derekcz] even mused that allowing hobbyists to capture these space views might earn the company some positive buzz, something Elon Musk never seems to get enough of.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A few weeks back we brought word that Reddit users [derekcz] and [Xerbot] had managed to receive the 2232.5 MHz telemetry downlink from a Falcon 9 upper stage and pull out some interesting plain-text strings.
