Re: [Discuss-gnuradio] Re: Problem with OTA capture examples

[Peter O'Doherty]

Okay sorry. I did try a search on Nabble but it didn't come up with any 
results.

Please bear with me for one last question:

Changing the command to
./am_rcv.py hf_10000khz_256_complex.dat 0 -O plughw:0,0

Just returns:
usage: am_rcv_file {file_name,'usrp'} freq_offset_KHz

But this seems to be exactly the imput I'm giving it. What am I missing? 
Many thanks,
Peter
