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

Thanks a lot. That does the job.

Can you please try using google before asking your questions here:
