Hello,
I am trying to receive two channels at once with the USRP N210 and a TVRX2
daughterboard. My code to set up the top block is below:
class collect_double_tb(grc_wxgui.top_block_gui):
def __init__(self,centerfreq0,filename0,centerfreq1,filename1,nsamples):
Hello,
I'm using Ubuntu 11.10, UHD 003.004.000, the USRP N210, and the TVRX2 card.
I am trying to use both the receive channels at once but I am getting a
strange error.
Below is my code:
self.Add(self.wxgui_fftsink2_0.win)
self.uhd_usrp_source_0 =
/lib/python2.7/dist-packages/gnuradio/uhd/uhd_swig.py,
line 2826, in usrp_source
return _uhd_swig.usrp_source(*args)
RuntimeError: Operation not permitted
Am I not calling the constructor for the source right?

It was this line that I needed:
self.uhd_usrp_source_0.set_subdev_spec(A:RX1 A:RX2, 0)
Also, I had to update my UHD drivers. Must've been broken somewhere.
Thanks!

Was anyone able to collect some ATSC data over the weekend?
Also bump about my question about which fr.atsc module does the symbol
detection and recovery.
Thanks!

Also, my research only deals with extracting the bit delay to the data sync
frame. So, I will not really be doing much with atsc decoding past getting
a bit stream what would include the sync frame. Which also
Nick,
I apologize if this is bringing back old ghosts but I am doing research with
ATSC signals and gnuradio and would like that sample ATSC capture that you
posted. i cannot find where you posted it. Do you happen to still have it?
Thanks,
