Hello All,
please anybody can help me?
I am using GQRX v. 2.17.6 with Ubuntu 25.04 in a VMware Machine.
I am trying to decode the satellites through  GQRX but despite i have the signal in GQRX
i do not get any decodes in Gnuradio.
I have also noticed that while receiving the satelllite if i record the pass and then pass it through the decoder in the gnuradio i can see the incoming data.
Please any help?
Thanks in advance

There are lots of options, but it sounds like you already have one solution. Rather than recording the data - pipe the data directly into gnuradio for processing in nearly real time.

GM Enzo,

Is it the audio stream or I/Q stream that you are recording but would like to pipe directly?

Audio stream is easy. I/Q stream is something I have never done, though maybe someone else can help with that.
