Tutorial: Creating an FM Receiver in GNURADIO using an RTL-SDR source

Over on instructables.com, user v3l0c1r4pt0r has created an instructable that shows step by step instructions on how to create an FM receiver in GNU Radio using an RTL-SDR and GNU Radio Companion. His instructable explains a bit about the theory of what is required to decode an FM signal, and shows which GNU Radio blocks are required, and how to connect them up.

    Did all that stuff with a virtual machine on vmware. Worked fine, but sometimes the audio sink is running low and it prints me some aU. Probably an issue with th vm. Thanks!

    Went through these steps today with great success. The hardest part was actually getting GNURadio-Companion to run on OSX.
