Yup, there's a huge number of protocols used for radio, too bad powerful software like Code300-32 still cost an eye. Tech specs are impressive, but still €4500 for the cheapest version. http://www.hoka.net/pdf/code300-32_spec.pdf
There are some FOSS demodulators out there, but unfortunately the number of protocols they support is way smaller. SigDigger however seems promising, although still in early stage of development.

Monitoring JWST transmissions, if doable, might be the next milestone for Ham Radio.
Already done by multipke people at the level of seeing the carrier.
No data decoded as that needs much larger dishes.
People have also been able to receive the carrier of various space probes orbiting Mars.
