Is just gr-qtgui your problem? Do you have libqwtplot3d-0.2.7-11.1.i586.rpm, libqwtplot3d-devel-0.2.7-11.1.i586.rpm and qwt headers? If not, you can get it from http://software.opensuse.org/search Please run ./configure without options and look for this line Not building component gr-qtgui and po

Hello all, I am facing an issue with an USRP2 with a RFX2400 daughterboard. I have observed that when the USRP2 is used for transmission/reception, it transmits/receives the first few packets successfully and then just dies. When this happens, its transmitted packets are not received by other U

Hi Matt, hope you had a good trip. We've managed to work around the ambiguity using calibration, but we are still interested in that other technique that you've mentioned earlier. Also we have trouble understanding the meanings of the phase ambiguities we are observing. We use a centre frequenc

Dear list, as you know, USRPs with a serial number below 500 cannot use newer daughterboards because they fail to send the motherboard clock to the daughterboard. There's a very simple modification that can work around this, and allow these old USRPs to use both old and new daughterboards. This m
