Hi all,
I have a 15 monitor. When I use two scopes or one scope and one FFT block in
gnuradio companion, I am not able to visualize the lower scope on GUI window.
Is this problem with the monitor or I have to change some settings.
Regards
GR

Thank you for the advising! That looks like something what i could use.
I just came up with another question:
I simply tried to simulate a DPBSK Path with noise, loaded from a file and
sinked to a file. Between Demod and Sink i placed a Pack K Bits with K=8.
Thanks! I see now what you mean, but how can i get rid of these boundary
mistakes? The Result is similar to the original, but the bytes are kind of
shifted. So from a FF 00 results a FE 01..

I have a USRP2 with WBX daughter board. Gnuradio and UHD were installed using
the attached script. I am running under Ubuntu 12.04.1 and GNU radio 3.6.3 was
installed. After doing some playing around with Gnuradio Companion I decided to
test out the hardware. I am able to ping the USRP2 but
Hi Martin,

Maybe only the pam_sync.grc is the most suitable for my purpose...

They are the same (RRC filter on both Tx an Rx).
Are you sure ?

Take a look at the packet_encoder and packet_decoder blocks. The
encoder adds a header to the packet, so that the decoder can
synchronise to it, and get the correct byte boundary. The
implementation (in the current master branch) is found at
gnuradio/grc/grc_gnuradio/blks2/packet.py.
On Fri,
Make sure you downloaded libboost libraries. Try the following in the
terminal
sudo apt-get install libboost1.48-all-dev
And rerun uhd_find_devices. If it doesn't work, try recompiling the UHD
driver after installing libboost, and then try uhd_find_devices

Thank you
This is actually what i would like to do later by hand. Isnt there a
possibity how i can fetch the raw bits or bytes directly after receiving?
Sorry if its a stupid question..

I don't know if it has anything to do with it but I recommend that you
try to run cmake, make and make test as a regular user, not as root.
ldconfig should have no effect on the make test step.

I don't understand you're question. What do you mean by fetch the raw
bits or bytes? It seems that you are already doing that fine with
your file outputs.

You are correct that the digital_constellation_receiver_cb does not do
any symbol timing recovery and that the documentation is incorrect.
Thanks for pointing this out, and sorry for the confusion.
