Re: [Discuss-gnuradio] Problem with dial_tone.py

2011-12-02 Thread Muhammad Rosli
Hi, It's because gnuradio cannot find your share file. Try to set environment variable of LD_LIBRARY_PATH and PYTHONPATH. For example, if you are installing gnuradio using default setting, you can setup the environment path in terminal as follow export LD_LIBRARY_PATH=/usr/local/lib export PYTHON

Hi all, I am a newcomer here. I previously use the build-gnuradio script to get a modern version of gnuradio and UHD. The script did a great job. But I guess some (small) updates are needed. One is related to udev conf. I saw the warning while booting my OS (Fedora 14): Starting udev: udevd[584]

Dear All, Please tell me the phase stability of 100MHz clock in USRP2 when the 100MHz clock is locked to an external 10MHz reference signal. I have measured the temporal variation of phase difference between two USRP2 outputs when a 10MHz signal is fed into PPS IN ports of two USRP2s. The input s
