Hi, I am new to gnu radio/usrp. I am trying out digitial TV application gr-atsc. I have a USRP N210 with a basic omnidirectional antenna. I checked local digital TV stations and found (from Internet) that there is one at 603.25 MHz (UHF channel 36) and the station is listed to be about 14 miles from here. When I run uhd_fft to receive the channel, I do not see any signal. I used a hardware oscilloscope to scan the UHF band, but could not find signal anywhere. Could it be because I do not have a good antenna (I have only basic omnidirectional antenna which looks like a 0.75 foot rod; sorry I do not have much communication engg background). Now, even without any TV signal, should the gr-atsc application Work? It is ok if it shows me a black screen from the mpeg file. But when I run the five python scripts (interp_short.py, xlate.py etc.), The mpeg file generated is of zero size. So I modified the python scripts to write to file (instead of fifo). What I found was that after runnin "btl-fsd-py", its output file is of size zero (other scripts before it generate file of huge size). What is the problem here?
Thanks. -Anirudh
