Re: [Discuss-gnuradio] Exploring the world of GNU

[Bari Bari]

Thanks for ur guadiance I ahave already installed GNUradio on ubuntu 8.1 from Synaptic packages  manager but I am not sure either any module or library is missing.
The gnuradio version is 3.0.4 2ubuntu2.
I have checked many examples , these are working but when i run fm example like $python usrp_wfm_rcv.py -f 104.5
I received folowing messages:

1- audio_alsa_sink[hw:0,0]: unable to support sampling rate 32000
  card requested 44100 instead.(I a using my Laptop Acer 5570Z series may be sound card not supported.)

2- FYI: No Powermate or Contour Knob found ( For this I read that there is no Problem,just for information)

3- "aUaUaU" is running  from FAQ I read that not enough samples to delivered to sound card. Its mean signals are not strong to listen FM here  in my Lab.

Is there any guidance to solve these problems.

Start here:

 http://gnuradio.org/trac/wiki

Note especially the GNU Radio FAQ and the USRP FAQ:

 http://gnuradio.org/trac/wiki/FAQ
 http://gnuradio.org/trac/wiki/UsrpFAQ

Download the code and build it:

 http://gnuradio.org/trac/wiki/Download
 http://gnuradio.org/trac/wiki/BuildGuide

Look at the examples in:

 gnuradio-examples

and some of standard utilities in:

 gr-utils

Assuming you've got a USRP, look at usrp_fft.py, usrp_oscope.py and usrp_siggen.py

Most commands support a --help option.  Try using it.

Also read the README files contained in the source code.


We've got a list of suggested reading:
