Hi Fabian,
That’s the corresponding issue for GetKISS+.
You select one satellite and hope that only this satellite will be received (and its data uploaded).
To be more flexible, I’ve built an uploader in gnuradio with blocks from gr-satellites which looks for callsigns and decides upon them to which Norad ID the data has to be uploaded.
One could use it while disabling the upload function of gr-satellites.
Let us hear (the other) Daniel if there is a way and if it makes sense to put this external uploader directly into gr-satellites.
