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
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?
Thank you for your consideration

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:

Do you have any hint for this?
Thanks, best regards.
