Hello,
sorry I had been out of office for some days.
When I run uhd_usrp_probe the error doesn't occur.
And using uhd.single_usrp_source doesn't occur either.
The complete output of the terminal is:
linux; GNU C++ version 4.4.1 [gcc-4_4-branch revision 150839]; Boost_103900;
UHD_0001.20101124
Got it. Saw the earlier message too.
Thanks

Of course its the same file. If you are making any changes in the C++ file
then you must compile it before you can see those changes. Did you do "make"
and "make install" after your changes?

Hi,
I found that for CFO compensation, there is the module named "costas_loop_cc
()"
Use it in this way: gr.costas_loop_cc(alpha, beta, max_freq, min_freq,
order)
where I can find this C++ file? I search the files, only found one
"gr_costas_loop_cc.cc" in ~/gnuradio-3.2.2/gnuradio-core/src/lib

Because GNUradio 3.2.2 was released before the WBX ... you will need
You should be able to setup an interpolating FIR filter to interpolate
by two and to shift your signal up or down by fs. Run each channel
though a filter (one up, one down) and add the resulting streams. The
resulting stream will have 2fs of bandwidth.

NIck,
What do you mean by "mix one sideband up and the other down"?
How would that go?
Thanks
Vlad.

I have done complete new installation of Ubuntu 9.04 Jaunty and installed
Binary packege of GNURADIO(3.2.2).
I have checked under usrpm folder usrp_dbid.py file. Following are the lines

I have a USRP board with a WBX daughter board and when I run
./usrp_benchmark_usb.py or any grc application like ./usrp_nbfm_ptt.py
these warning messages appear:
Testing 2MB/sec...
