Hi Varun;
Are you running grc from a graphical menu? If so try running it from a
shell - it may be reporting something on stderr.

Hi all,
We are using USRP1 and 2 WBX d'boards to implement a transmitter with two
antennas.
Since the two d'boards are synchronized, it was easy to implement.
Now we're planning to implement a system with more than 2 transmit antennas.
Is it possible to have more than 2 transmit antennas with US

Hi,
is the combo RFX400 with UHD supposed to work ?
I tried the example ./tx_waveforms and it doesn't seems to work, even
if the device is recognized.
Using a WBX I get the expected result.

Hello list,
I have two USRP1s and four DBSRX2 daughterboards. I would like to
synchronise the USRPs, to build a coherent, sample aligned, four channel
receiver (inputs from four separate antennas). I had hoped I could do
this by modifying and connecting the boards as described here:

Hi,
I am thinking to integerate my SystemC code as a SP block with GNURadio...
Is there anyone who have experience about this?
SystemC is a spereate C++ library.

g0tcha -
Your problem isn't actually related to GNURadio in any way - it is
only about the USRP. Direct your question to the USRP users list, run
by Ettus Research, and you might have more luck:

Moin,
these are my first steps with GNU radio. I'm building an I/Q mixer at the
moment to make some experiments with a simple AM receiver. It should use the
sound card yet.
I wonder where I can find a simple grc-file for Comprehensive GNU Radio. This
would make the beginning much easier for me.

The mux value calculation is not exposed. Rather, you specify channel
mappings:

Hi ,
I am new to GNU Radio and am facing difficulties in implementing DQPSK
modulation on Gnu Radio Companion. The system works fine , but for one small
glitch. The DQPSK modulator/demodulator's input and output are in Byte
format, which makes it a little hard to comprehend the output.
