Dear friends, thanks a lot for your responses.No WBFM music yet. Just to share; I followed these steps which fail: 0. Flash and setup with RaspberryPi4 the 32GbSD Card from Raspberry Pi image file: "2020-02-13-raspbian-buster.img" 1. run "sudo nano /etc/apt/sources.list" and replace "buster" by "testing" 2. run "sudo apt update" 3. run "sudo apt full-upgrade" 4. run "sudo reboot" 5. run "sudo apt install gnuradio" 6. run "sudo reboot" 7. Validate is GUI:Start>Programming>GNU Radio Companion>Help>About shows "3.8.1.0(Python3.7.6)" 7. Loading a hello-world FMWB example showed Missing Block "rtlsdr_source" so end GNU Radio Companion (I have a RTL-SDR stick) 8. run "sudo apt-get install gr-osmosdr" 9. run "sudo apt-get install xterm" 10. sudo reboot 11. run "sudo apt autoremove" 12. Loading the FMWB example again I noticed that there were no Missing Blocks anymore and that "rtlsdr_source" could be used. 13. Generating flow seemed to be going okay. 14. Executing flow generated the failure: <<< Welcome to GNU Radio Companion 3.8.1.0 >>> ...Warning: failed to XInitThreads() 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 [INFO] [UHD] linux; GNU C++ version 9.2.1 20200104; Boost_106700; UHD_3.15.0.0-2 Assertion 'close_nointr(fd) != -EBADF' failed at src/basic/fd-util.c:71, function safe_close(). Aborting. >>> Done (return code -6)
I continue with the suggested SDRPlay asap and share the results! No matter how, but the music will Sound!
