NBFM problem with rtl_fm on Raspberry Pi 2
by Hayati Ayguen 15 Jul '15

15 Jul '15

Hi, i'm experiencing problems demodulating (NB)FM with rtl_fm, when compiling directly on Raspberry Pi 2 with Raspbian: i just get noise! WBFM does work. And i tested many things like calibration, frequency, samplerate .. directly with a LPD (low power device). rtl_tcp works nice with SDR# and i can verify the calibration with it. In the end, i got paranoid and thought of compiler errors. So i tested the same on a Raspberry Pi (1) B+ with same Raspbian image: That works good. No problems! Anyone else experiencing the same problem? What is the solution? kind regards, Hayati

osmocom app GUIs don't look correct
by Urban Hakansson 14 Jul '15

Hi everybody, I have a problem. Yesterday I installed Fedora 20 (x86_64) laptop the following, bladeRF from nuand, and UHD + GnuRadio + gr-osmosdr + gr-iqbal etc... using Marcus Leech's build-gnuradio script. "$ wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio" I know have installed the following versions. 1) bladeRF: libbladeRF 1.4.0 bladeRF-cli 1.2.0 FPGA: 0.3.0 Firmware: 1.8.0 GnuRadio 3.7.7 UHD 3.9.0 I am running the osmocom_fft utility on both the Ettus B210 and the bladeRF. osmocom_fft -a bladerf=0 -s 1M -f 947M osmocom_fft -a uhd -s 1M -f 947M Both seem to be running fine except that the GUI does not look correct. Please see attached images showing two screen shots of the osmocom_fft GUI. Nuand bladeRF: Center Frequency and Gain Settings are messed up. Text and sliders missing, and the boxes with the actual values are not in the right location. Ettus B210: Center Frequency and RX Gain are messed up.Text and sliders missing, and the boxes with the actual values are not in the right location. Side note: uhd_fft runs without any problems (on the B210) and the GUI looks correct. Nothing is missing or in a strange location on the screen. What can be causing this? How can I fix it?

Hi there, In debian, sdrangelove is having some build issues on mipsel [0]. At first, there was an issue regarding the '-msse2' switch. If I delete the switch, then another build error happens: ======== 8< ======== [...] [ 21%] Building CXX object CMakeFiles/sdrbase.dir/sdrbase/dsp/interpolator.cpp.o /usr/bin/c++ -DQT_CORE_LIB -DQT_GUI_LIB -DQT_MULTIMEDIA_LIB -DQT_NETWORK_LIB -DQT_NO_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DUSE_FFTW -Dsdrangelove_EXPORTS -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -O3 -DNDEBUG -fPIC -isystem /usr/include/mipsel-linux-gnu/qt5 -isystem /usr/include/mipsel-linux-gnu/qt5/QtCore -isystem /usr/lib/mipsel-linux-gnu/qt5/mkspecs/linux-g++ -isystem /usr/include/mipsel-linux-gnu/qt5/QtWidgets -isystem /usr/include/mipsel-linux-gnu/qt5/QtGui -isystem /usr/include/mipsel-linux-gnu/qt5/QtOpenGL -isystem /usr/include/mipsel-linux-gnu/qt5/QtMultimedia -isystem /usr/include/mipsel-linux-gnu/qt5/QtNetwork -I/tmp/buildd/sdrangelove-0.0.1.20140824/obj-mipsel-linux-gnu -I/tmp/buildd/sdrangelove-0.0.1.20140824/include -I/tmp/buildd/sdrangelove-0.0.1.20140824/include-gpl -fPIC -o CMakeFiles/sdrbase.dir/sdrbase/dsp/interpolator.cpp.o -c /tmp/buildd/sdrangelove-0.0.1.20140824/sdrbase/dsp/interpolator.cpp In file included from /tmp/buildd/sdrangelove-0.0.1.20140824/sdrbase/dsp/interpolator.cpp:4:0: /tmp/buildd/sdrangelove-0.0.1.20140824/include-gpl/dsp/interpolator.h:4:23: fatal error: immintrin.h: No such file or directory #include <immintrin.h> ^ compilation terminated.
