Gnuradio like GQRX

My name is Pierre Dibo and i work on the Cubesat project IGOSat.
I would like some help about gnuradio and how to produce a flow graph like GQRX to get the data send through our SDR.
More detail on this web page because i cannot post more than one image as a new user.
Thanks for reading me.

I found a solution so i will post it on the git but in summary i followed how gr-soapy do fm_radio_receiver_soapy
It work for my needs but it may not for others.
