-"""
-Here is a bit of code that will receive SCA analog subcarriers of FM
-Broadcast Stations using the USRP. It is a modified version of
-usrp_wfm_rcv.py.
-
-Common SCA frequencies are 67 kHz and 92 kHz. SCA is used for Reading
-Services for the Blind, Background Music, Foreign Language Services, and
-other services. Remember you may hear static when tuned to a FM station
-because this code only outputs SCA audio.
-
-The USRP gain is critical for good decoding. Adjust for minimum noise.
- I use the Post FM Demod FFT to check for SCA subcarriers and to adjust
-the USRP gain for the lowest noise floor. The stereo pilot at 19 KHz,
-the stereo difference signal around 38 KHz, and RDS at 57 KHz are also
-displayed on the Post FM Demod FFT if present.
-
-The range below 67 kHz is used for SCA only when Stereo is not used.
-
-The SCA recieve range is not as far as the main FM carrier receive range
-so tune in strong local stations first.
-
-I tried to comment the code with the various parameters. There seems to
-be several choices for a couple of them. I coded the common ones I see
-here.
-
-In the local area there are a couple of stations using digital SCA.
-These look similar to narrow DRM signals and I wonder if they are using
-OFDM.
