Hi all,
According to the tutorial of Gnu radio / python applications, It is possible
to create Hierarchical blocks. However when i try to implement it i get some
errors. is it possible to trace the flow graph while its is running to check
where the error is ? how? / OR is my using of connect meth
Hello, Johnathan,
I am wandering whether I should uninstall every gnuradio pack in Ubuntu 9.04
and use source
code to install it again? Or I just need to use source code install update
for new version?
If I need to remove all binary package. How can I check that I have removed
the gnuradio bin

Andy, I did forget to mention to you that the USRP2 specific problem
has been fixed in the git master branch since the 3.2.2 release.
You'll need to switch from the binary in
Hello, Firas,
Yes. I have tried it like that:
def main():
t = my_top_block()
while 1:
t.start()
print t.c2mag.level()
time.sleep(3)
t.stop()
Hi,
The xxx.stop() and xxx.wait() should be called after time.sleep(xxx)

I need to process signals from 4-49 mhz on a private coax tv network. What type
of hardware filter will i need to not blow up the LF-RX?

Has there ever been any discussion of adding an I/Q imbalance correction
block into the Rx chain in the FPGA image on the USRP/USRP2? On past
systems that I've worked on, the calibration procedure to get this imbalance
reduced can take quite a long time and still only produces moderately
improved

However, one thing I don't understand is that the mirror frequency
doesn't turn up on exactely "-f" but a few Hertz off. I don't get this.
Are we sure that the down-conversion on the FP

There isn't a source for that. You would need to create a
hierarchical block with the needed blocks and wrap in a GRC wrapper.

Hi Firas,
But it shows the same error as before. I am doing tests like that:
def main():
t = my_top_block()
t.start()
t.wait()
t.stop()
print t.c2mag.level() #print power
time.sleep(3)
I also have a xcvr2450 that won't lock sometimes. This is at 2.4GHz.
Also an issue about IQ imbalance:
I am measuring IQ imbalance. The values are generally quite good.
However, one thing I don't understand is that the mirror frequency
doesn't turn up on exactely "-f" but a few Hertz off. I do
