Thanks Tom and Adeel for the suggestion.
We have sorted out the problem and now our system is working at low data
rates.
The real problem was with our *high pass filter* block. We are using it to
eliminate the DC-shift present at the output of quad_demod block. But its
not working at low data

Have USRPn210 with SBX daugtherboard. I installed the gnuradio and Uhd.
But have problem that the PC not see the USRP. i edit the ips to make
the device 192.168.10.2 and same problem. so, can any one help me to
connect the USRP with the PC( the IP , DNS, and the Default gatway).
The last device I received did not appear to have the correct IP set from the
factory.
I had to reset using the Device recovery and bricking procedure here:

Hi Andrew,
It will be cool to get one of those boards, I see a lot of potential with
the combination of Zedboard and Myriad RF, it can be a comple SDR platform.
I would like to know more about the board and when it will be available,

I love the 6 GHz capability, but I really miss full duplex, this locks out
stuff like OpenBTS or the open source LTE system everyone is hoping for :)
For the moment I will go with the BladeRF, also a small design, nice for
travel. Still I am tempted to order a hackrf :)

Hi BZS,
did you install python development headers?
If unsure, please install Gnuradio by downloading pybombs (as described
in http://gnuradio.org/redmine/projects/pybombs/wiki), and installing it
that way.
git clone git://github.com/pybombs/pybombs
cd pybombs
./pybombs install gnuradio
I am also interested in this topic, since I was unable to configure MM
bloxk once. In fact it was working for 26 samples per symbol but for 5 not.
Could you provide some more information?

When I run it, UHD fires the following warning (and transmission seems

Hey Marcus, thanks for answering.
(1) 720Khz is not an exact integer fraction of 64MHz (the sampling rate
of the device)--so it rounded
(2) It's warning you that you'll get a humped frequency response with
more rolloff than you'd like, due to the rounded-down sample rate

How wide is your signal?
Then find the nearest sample rate your_bandwidth that satisfies the desired outcome that the computed
interpolation rate (64.0e6 / desired_rate) is an even number.
If the signal has artefacts that "spill" outside the required sample rate, then, yet, filter it first.

I am using the GNU Radio DQPSK Modulator and Demodulator for low
rate data transfer. I know that GNU Radio blocks are already tested. So
is there any BER curve available for the DQPSK Mod/Demod.
Did any one characterized the BER curve of this block.

change their sign in gnuradio
One question. I have tried your simple_fm_rcv and a similar version that I
made on my own. In both cases I have found that there is a phase shift in
the pilot tone. In the image the red
