In the tutorial for increasing bandwidht (https://www.nuand.com/large-bandwidth/), there are a few things to notice:
1) In To compile and run gr-osmosdr, the path says gnuradio-builds with an extra "s"
2) I would add the following at the beginning:
apt install libqt5svg5-dev libpulse-dev apt install qt5-default
3) But for gqrx I cannot compile from your source:
/home/sdr/software/gnuradio-build/gqrx/src/applications/gqrx/receiver.h:34:10: fatal error: osmosdr/source.h: No such file or directory
I don't know where to put the osmosdr folder for the compiler to see the included file. Any hint?
Thank you!
