Hi all,
I now have some success. One of my USRP was faulty.
My problem is now that my received file is not complete( the first 150 lines
are missing approx)

Having tried the several options from Derek and Mojtaba find myself lost still.
To summarize I am trying to send a file, whether that be complex (Jpeg) or
simple (txt) through a pair of USRP.
To start with I created a single flow graph with bit conversion encoding and
modulation, this works. I then used the same blocks but added the USRP
source/sink to and this does not.
The symptom is a received file of 0byte size coupled with no output from the
decoder.
I can therefore assume no valid signal is being received. I don't believe this
to be any of the previous blocks as they did work.
Could it be a synch problem between the USRP or too noisy....and is there a way
to test the USRP back to back not over the air.

I have tried both options unsuccessfully........ I will add them to my combined
flow and check there.

If you have access to the examples available in GNURadio package, please check:
\examples\digital\packet
Or
\example\digital\demod
The parameters are straight forward though.
Samples Per Symbol for your case is 2.
Filter Rollof Factor of 0.35 is fine.
Prototype Filter Size of 44 or 45 does the job.
Loop Bandwidth is the famous constant of 2*pi/100.
I use these values and the flowgraph seems to be fine. I hope they do the same
for you.
Cheers.
