GNU Radio Companion Sandbox

Workspace for my GNU Radio Companion flow graphs. I figured other people starting out in the world of SDR may find these useful.

Dependencies

1. Osmocom RTL-SDR driver and gr-osmocom (http://sdr.osmocom.org/trac/wiki/rtl-sdr)

• The RTL-SDR blocks could be swapped out for other SDRs

2. GNU Radio 3.6.3 with GNU Radio Companion (http://gnuradio.org/redmine/projects/gnuradio/wiki)

• Older versions may work also, but I'm using 3.6.3

GRC Files

• nbfm_file: Narrowband FM receiver from a file (see voice_spec.grc)
• nbfm_rx: Narrowband FM receiver using the RTL-SDR
• spec_fft: Simple FFT dump; adjustable range covers typical RTL-SDR frequency range
• voice_spec: Narrowband FM "transmitter"; just dumps to a file (for use in nbfm_file.grc)
• wbfm_rx: Wideband (broadcast) FM receiver; good for listening to local FM stations
