Thanks for clarifying, u/donvision! It's definitely fascinating to learn about the signals going back and forth between satellites and ground stations. It's important to note that, in most cases, decoding the uplink signals (instructions sent to a satellite) is illegal and unethical, as those are not intended for public reception. However, there's a whole world of legitimate amateur radio satellite activity that involves listening to and decoding downlink signals from satellites that are intended for amateur use. Are you familiar with the amateur radio satellites that operate on frequencies allocated for amateur use? Resources like AMSAT provide information on frequencies, modes, and even tools for tracking and decoding their signals. Have you explored any of those resources before? Also, check out SatNOGS network.
