Hi,
True, I also updated the satnogs_lrpt_demod.py script to always dump the iq file, but to my understanding this can also be configured in satnogs_setup.
The sat_id is extracted from the TLE data. I used a TLE data argument because that is available als a post observation script argument out of the box, no changes necessary. Instead of the full TLE you can also use the --sat_id argument to pass the sat id, which is easier when you start the script by hand.
