ok thaks. I wasnt sure if i should add attunetion or simply decrease tx power. Now that im thinking about it, maybe its not really neccessary to sweep the feeq range? The usrp could just shoot a 8mhz wide signal (noise?) into the thing, and visualize in realtime the notches and pass bands

[Discuss-gnuradio] stream tags in Python

2011-12-01 Thread Yan Nie
Dear all, I need to use stream tags and the get_time_last_pps informations to control the received data storage. I am wondering how to get the stream tags in Python? I tried the method used in C++ and transfered in Python     samp0_count = self.nitems_read(0)    

[Discuss-gnuradio] Gr-UHD thinks i have the wrong firmware

2011-12-01 Thread Scott Johnston
Hello, Why does gr-uhd think I have the wrong firmware, when UHD says I have the right firmware? I am getting the expected compatibility number 8, but got 6 error with gr-uhd, but all the UHD example work properly. The background is that I recently upgraded to gnuradio 3.5 but then

[Discuss-gnuradio] which math library to link with

2011-12-01 Thread Achilleas Anastasopoulos
We are writing a block that requires SVD of matrices. Is there a preferred library (eg, LAPACK) that other gnuradio blocks are already using that we can link with. I don't want to add another library dependence... thanks Achilleas ___ Discuss-gnuradio

Hi, Thanks for your reply. I am using the narrowband example. If I attempt using ./benchmark_tx.py -f 400M -r 250k -S 4 and ./benchmark_rx.py -f 400M -r 250k -S 4 which I worked out from reading the README file, the receiver still output overrun (many '0'). I verified that the transmitter
