I am part of Auburn University’s Software Defined Radio Senior Design
Software being used:
Ubuntu v.9.10 on xfs partition
GNURadio v.3.3 (git)
Available hardware: USRP1, USRP2, WBX daughterboard, TVRX daughterboard
We followed the instructions in ./gnuradio/gr-atsc/src/python/README to
Using the FFT we found 507.25M to have a strong signal.
this is channel 20.
And according to
this is WCOV from Montgomery, Alabama.
So we do have the correct video carrier frequency, which I assume is the
frequency we want to record and decode into a video.
Question #1) Is the video carrier the one that carriers the video, or
would it be the ATSC carrier?
We then used:
./usrp_rx_cfile.py -s -d 10 -g 20 -f 507.25e6 atsc_data_6-4m_complex
/tmp/atsc_pipe_5 never fills with data.
The output file, ‘test.mpeg’ is empty.
Question #2) What do we need to fix to get /tmp/atsc_pipe_5 to fill.
Question #3) What do we need to fix to get temp.mpeg to fill.
