Hello GR, I tried to capture some TV broadcast video frames using
rx_samples_to_file --args "addr=myusrp" --file myfile.dat --time 120 --freq 450.75e6 --rate 5e6 --gain 30 Then I tried to play back that file using : tx_samples_from_file --args "addr=myusrp" --file=myfile --type short --rate 6.25e6 --freq 485e6 --gain 20 –repeat However I was not able to get anything on the TV. Am I missing the center frequency for the capture (I tried to capture WUSA-HD) I think the TV is already tuned to listen to 485e6 but I am not sure. Am I missing something or may be I should do automatic tuning for the TV to be sure to listen to 485e6 Hz.
