Tom,
I use Ubuntu 9.04 and QWT-5.0.2.
Thank you!

I tried the code of 'Tutorial - Using the QT GUI Blocks in GNU Radio', but
error occurred.
Traceback (most recent call last):

Hi,
I'm trying to use USRP to receive signals and collect the samples.Here is
the flow graph:
usrp_source_c-->stream_to_vector-->complex_to_mag-->vector_sink_f
dst = gr.vector_sink_f()
data = dst.data()
In my opinion, what stores in data should be the amplitude of the samples.
Hi, all
I want to plot a figure with the samples from usrp, but I have some questions.
Here is the flowgraph:
usrp.source_c --> gr.streams_to_vector(gr.sizeof_gr_complex*1, 1) -->
gr.complex_to_mag(1)
--> gr.message_sink(gr.sizeof_float*1, self.msg_sink_msgq_out, True)
Here, self.msg_sink_msgq_o

Hi,
I wonder how can I get the dBm value by using usrp_spectrum_sense.py.
should I do it as follows?
fft = gr.fft_vcc()
c2mag = gr.complex_to_mag_squared() (or without squared?)
log = gr.nlog10_ff()
stats = gr.bin_statistics_f()
self.connect(self.u,s2v,fft,c2mag,log,stats)
in main functio
Hi,
I have some difficulties in unserstanding the statements belowin
usrp_spectrum_sense.py.
fft = gr.fft_vcc(self.fft_size, True, mywindow)
power = 0
for tap in my wondow:
power += tap*tap
What is stored in window and what is tap? Where is the FFT data stored? I
turned to C++ file gr
Thomas，
Thank you for you answer. Do you mean I can not achieve the goal by modifying
its softare code beause of hardware restriction ? I have nothing to do except
using more usrps?Thank you!

Hi all,
I want to use tunnel.py to make a usrp with two daughter boards work as two
pieces of wireless cards. The first time I run tunnel.py, it works well, and
generate gr0. But when I run tunnel.py for the second time (in another
terminal) to configure the other daughter board, it turned out
