I saw this function but never used it before.
Guess the satellite names in sat_app.ini must match those in TLEFILE.txt
Additionally you have to adjust the port and the path to the SoundModem files.
As for the TEVEL2 satellites (the last entries in your sat_app.ini) it’s currently not recommended to use GetKISS+ for uploading unless you play the recording after the pass to go packet by packet to know in advance from which of the 9 satellites the next packet will be and switch GetKISS+ each time to this satellite.
Otherwise you will upload packets to the wrong SatNOGS satellite entry.
SatNOGS will count those entries too, but they are meaningless and if there is a dashboard it could lead to false values being displayed.
If you like to upload TEVEL2 packets during the pass, I recommend Gr-satellites UPloader. Perhaps a or the next step in uploading packets.
GetKISS+ should be understood as a (first and) simple way, but simple also as in limited.
