Hi, I do not know if my problem is like your.But 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:
./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). Besides, Tvoid does not work right now. My USRP does not receive from the RF. What could be happening? Thanks in advance.
