 1. Verify RTL-SDR can tune to a commercial FM radio station with `rtl_fm` program. The command below pipes raw data from `rtl_fm` into to sox `play` which will then decode the raw data to produce audio output. Modify the value after the `-f` to specify your own FM station/frequency (98.8 is BBC Radio One in the UK).
