As I posted before, after
installing Gnu Radio (3.1.3 tarball) I tested my USRP and Dbsrx
daughterboard when usrp_fft.py and I could see gsm spectrum without
problems. After that, I installed Tvoid to decode gsm channels and it
worked. Now, I do not know what happend. When I type something like:
./usrp_fft.py -R A -d 64 -g 20
show me the sprectrum like noise ( I have seen the whole band - 800- 2400Mhz like noise at the same level). My dbsrx is in slot A. Besides, Tvoid does not work right now. My USRP does not receive from the RF.
What could be happening? Is there any way to test dbsrx? Was able to change the configuration of the FPGA? I do not think so.
