Re: [Discuss-gnuradio] Reception problem with gsm-tvoid and gsmdecode
Thank you for your reply Eric. I asked this question in gnu radio mailing list because may be the problem is the hardware. I could see there was a problem with the synchronization. Sometimes, some gsm messages are missed due to a synchronization lost. Besides, i think it can be enhanced by software. Do you think the hardware (USRP) is not the problem? Thanks.

Re: [Discuss-gnuradio] Tuning problem - usrp_fft.py
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. Sincerely, Jose 2009/2/3 Fabian Uehlin m...@fabian-uehlin.de Hello! I have a Gentoo Linux system with KDE and the current svn version of GNURadio and OpenBTS (revision 10370). Because tuning of my two daugtherboards (RFX-1800, USRP1) failed with OpenBTS, an user give me the hint to run usrp_fft.py. So I run usrp_fft.py -R A -f 1724.4e6 or usrp_fft.py -R B -f 1724.4e6 It returns Segmentation fault nothing more. Running usrp_siggen.py -T A -f 1819.4e6 or usrp_siggen.py -T B -f 1819.4e6 returns Using TX d'board A: Flex 1800 Tx MIMO B or Using TX d'board B: Flex 1800 Tx MIMO B nothing more. The main problem is, that OpenBTS occurs an error, that the daughterboard could not tune to the desired frequency. So I tried to fix it, but without success. But now it seems, there is a general problem with tuning my USRP/daughterboards?! What could be the problem? Does anyone have an idea?
