Hi
I am using Fedora 6, on HP Pavilion 5000 laptop, with USB 2.0, a new USRP
board (tested at Jan 2007) and GNUradio 3.0 installed without any problem.
The board is seen as USB 2.0 device (when I used usbview).
Now, Whenever I try to run any example in the gunradio-examples directory i
get the

Got it! It's the line:

I just posted this on the Ticket:

The error was introduced in [4255]. I can verify this because [4254]

Yup, adding /usr/local/lib to my ld.so.conf file did indeed fix the
problem. 4718 now builds cleanly. Thanks for the tip.

Hello Roshan,
Out of curiosity did you try adding
/usr/local/lib
to your
/etc/ld.so.conf
file
This worked for me on my Debian distribution.

I would like to add some type of carrier recovery to the GMSK demodulator in
GNU Radio, however I am having a bit of trouble getting something
implemented that works properly. I have tried using gr.costas_loop_cc to
add a costas loop for carrier recovery, but I am not quite sure how to
calculate

Once such a packet is found then the flowgraph has a message sink
and puts this half-baked packet in this queue, together with
possibly another message of a different TYPE (control message) with
some parameters required in the second flow (such as initial phase
estimate, etc).

Trond,
I am glad you asked this question in such an eloquent way.
This has been my question about Gnuradio for a long time.
One way around it (not sure if it works for all scenarios)
is for the flow grap to communicate with the main pyhton program and the
rest of the flowgraphs through massage
Thanks for the advice. I don't think that's my only problem though. My vector
is currently supposed to produce 2500 samples. This combined with an
interpolation factor of 512, should give me 10 msecs of signal. Have I
calculated this correctly? Also, I'm using the gr.modulation block to make the

what is the receive PGA set to? I find it works best at the midpoint
(35 or so). you may want to simply scale back your transmit power
