I just got a USRP, and I'm learning how it works.
I'm having trouble getting the ATSC demod to work.
The WFM demod works OK, so I know the antenna, etc works.
I know I'm tuning the right frequency (KQED with a center
frequency of 569MHz), because I can see the signal with usrp_fft.
I got a few underruns during the "usrp_rx_cfile". About 10 in 10
seconds. The raw data file is 446 meg.
I get an empty output file and a file named "taps.txt", which is
also empty.
I tried both the Gnuradio v3.1.2 (in Fedora 9) and the Gnuradio
from SVN.
I get a few output strings, like ">>> gr_fir_fff: using SSE" from
btl-fsd and ">>> gr_fir_fff: using SSE
Setting initial_freq: 3065000.000000" from fpll
Do you have any tips on finding the problem?
Thanks.
