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

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?
Thanks Regards
-Fabian-
