Hi, My system is ubuntu 20.04 and gnuradio3.9. Im trying to run the program and get the followig output,

michael@ubuntu:~/Desktop/gr-iridium-maint-3.9$ sudo iridium-extractor -D 4 examples/rtl-sdr.conf > output.bits [sudo] password for michael: gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.9.5.0 built-in source types: file rtl_tcp rfspace redpitaya Traceback (most recent call last): File "/usr/local/bin/iridium-extractor", line 356, in tb = iridium.iridium_extractor_flowgraph.FlowGraph(center_frequency=center, sample_rate=sample_rate, decimation=decimation, File "/usr/local/lib/python3.8/dist-packages/iridium/iridium_extractor_flowgraph.py", line 130, in init source = osmosdr.source() RuntimeError: No supported devices found (check the connection and/or udev rules).

I assume its because the RTL-SDR is not recognized by gr-iridium. I tried to install gr-osmosdr but it didnt help. The RTL-SDR is recognized by other tools, like CubicSDR.

How can I solve this issue?

Thanks!

Please look at built-in source types Here is a sample of mine: gr-osmosdr 0.2.0.0 (0.2.0) gnuradio 3.8.1.0 built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy airspyhf soapy redpitaya freesrp That's a point you can look at
