i want to capture the final minutes of my local tv channel shutting down
usrp_rx_cfile.py -f 55250000 -R B -d 8 -g 60 analog_ntsc_capture.dat
this should work right? channel 2 is 55.25mhz according to

Not sure but you should test it out in advance.
yeah i see a nice spike on the fft but i cant think of a way to test…
i do get some uOuOuO, but not many. dont think it should be a big
problem…
i will post whatever comes of it, and post it on my website, maybe
someone
can try it

The middle of north american channel 2 is 57MHz.
The other number is probably the video carrier.

Your gain seems pretty high. I suggest you take a look at the
signal using usrp_fft.py and work out a gain setting. You don’t want
to start raising the noise floor.
