Hi Sudarshan,
try the app usrp2_rx_cfile.py or usrp_rx_cfile.py depending on your usrp
version
to store the raw data.

suggest you open the "logging" flag, then have a look at the data file to
find which block doesn't work well.

1) make sure to run the apt-get install command under the jaunty section
http://gnuradio.org/trac/wiki/UbuntuInstall
2) now you can run these commands (you may need to install git)
git clone http://gnuradio.org/git/gnuradio.git
cd gnuradio
./bootstrap
./configure
make
sudo make install

for dbpsk modulation is correct:

Do anyone have any experience in receiving and transmitting DRM radio
using USRP and GNURadio?

Hello,
the following code snippet is part of a runnable python script.
I want to control some or one of the I/O pins on the USRP / LFTX board but I
can't measure any changes on the USRP / LFTX io_pins by using the following
code snippet.
Could somebody give me a hint please what to do ?

Great news. The basic issue is that since the halfband decimators
decimate by 2, they have an internal state (which we call odd or even).

Try this dial tone, it should come with your gnuradio install:
