Greetings!
While the OPS-SAT team has provided links to numerous GNU Radio flowgraphs, I wanted to share a very basic .GRC file to feed properly formatted payloads to their GUI App as well as, optionally:
.SatNogs
.Direwolf
.local .KSS file
… with the source either being an AUDIO file that you might have recorded (sample file also at my URL) or ‘live’ FM audio from the SDR of your choice. My flowgraph is already setup for GQRX because that’s what I use, but if you have another method of connecting audio from your favorite SDR app to GNU Radio, you’ll already know how to add that to this framework.
My files are at:

… and the OPS-Sat GUI app (+ other info) is available at:
