I recently begin to use GNU Radio to receive ATSC signal. The GNU Radio
is the most updated Developer version on Ubuntu 9.04. I followed the
README in /gnuradio/gr-atsc/src/python/. I set the frequency to be 557M
decimation to be 10 and number of samples to collected to be 200M. There
overrun or under run during collecting the data. After excuting
interp_short.py, xlable.py, fpll.py, btl-fsd.py and viterbi-out.py, the
file is empty. I set each of the py programs to output file, and saw
output of btl-fsd.py is empty. There were someone posting a similar
the disscussion list, but I didn’t find the answer to that. Do you have
opinion about this? Is the parameters setting causing the problem or I
operating this incorrectly?
Thanks a lot!
