Problems with USRP


#1

We are new in gnuradio and we are trying one example called
“usrp_wfm_rcv.py” but we have some problems when it is executing.

Inserting the commands:

export PYTHONPATH=/usr/local/lib/python2.5/site-packages/

python usrp_wfm_rcv.py -f 90.9M

the output is:

Using RX d’board A: LF Rx

gr_fir_ccf: using SSE
gr_fir_fff: using SSE
audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000
card requested 44100 instead.
FYI: No Powermate or Contour Knob found
