Hi Jim,
that's good news so far :)
So, each time you run your flow graph, the following line should
change:
monitor::endpoints() = -h vmware -p 40161
at least in the port number at the end.
Now, remove the ctrlport monitor from your flowgraph (disable it);
start your flow graph and let it run.

Dear Kunal,
This is not "moving average", this is normal "average".
I agree with Marcus' explanation, you don't need the "set_history()".
Moving average is:
1st output = average of 1,2,3,4,5
2nd output = average of 2,3,4,5,6
3rd output = average of 3,4,5,6,7
4th output = average of 4,5,6,7,8

Hi,
I am running siggen and oscope test with USRP1.
I am expecting a smooth sine waveform with this:
c[r...@fodora usrp]# usrp_siggen.py --sine -f 1e6 -i256
Using TX d'board A:
But I am getting some error in oscope.py and the attached oscope output does
not give me the expected waveform

Hello, everyone
I am now trying to check whether there is any nonlinear amplifier on the Tx
daughterboard. Could anyone tell me which device finishes the task of nonlinear
amplifying on the Tx board? Thank u It is very emergent! Thank u!

Hi all !
I am interested in observing spectrum around 200kHz and tried the following
command :
./usrp_fft.py -R A:0 -f 20 -d 112
with a coil antenna connected to RX-A input of LFRX daughterboard.
Should it work ?
If so, does it mean that there is something wrong with my antenna ?
Regards,

Hey all,
I'm looking for some help building features/inband-usb
Eric and I couldn't exactly figure out what causes this at the hackfest, and
I've spent
some more time with it and still can't figure it out.
the root of the cause is in usrp/host/lib/inband and usrp_rx.cc
it builds, but does not

I have been able to eliminate the make check error for gnuradio-core but not
the make check error for cppunit by using up2date to install pretty much
every update available. However I've run into another error.
I get the whole down to the installation of gr-usrp (following KD7LMO's
method) and w

I am running a Pentium architecture. I tried using an older version of GCC
(3.2) per someone else's instructions but it did not get rid of the error
during the make check of gnuradio-core. I tried doing a make check on all
of the baseline instlals from KD7LMO and found the following error when

Hello all,
I am trying to install GNURadio on a Fedora Core 4 system following the
instructions at http://www.kd7lmo.net/ground_gnuradio_install.html. I
completed the baseline install process (skipping the two octave installs
because I don't need them) and proceeded onto the gnu radio portion of

Hi,
I've got gnuradio up and running and am now trying to get a better
understanding of how to use it before beginning more involved
projects. I am trying to write a py script that displays an oscope
from a PCI-DAS4020/12. mc4020_fft.py runs and displays the
excpected results. Here's the code

Make sure to install the various -dev packages, e.g. python-dev, etc.
I'm not really sure what the exact names are, adjust as appropriate...
This goes for all the libraries that gnuradio requires.

Hello All,
I need your help. I'm a nube to Linux and have been trying for two
weeks to get the radio core installed. FC3 installs Python
in /usr/lib/... instead of /usr/local/lib. I've tried installing a
version in /usr/local/.. but the RPM manager didn't like that so I
