Re: [Hackrf-dev] I only get flat noise in gnuradio

[Juan Antonio]

In the end the problem was in the Rf Gain control, it was too high

Hi Juan,

That is great, because the other software works fine with the HackRF and
hackrf_info finds it and it is up to date, it means that your hackrf
hardware works and the drivers are all correctly installed and recognizing
it. The problem is in the set up or configuration gnuradio. I have found
the #gnuradio IRC channel on freenode to be helpful for configuration
issues like these.

[Hackrf-dev] I only get flat noise in gnuradio

[Juan Antonio]

I can not get the hackrf to work well with gnuradio, the only thing that
comes out in qtgui_freq_sink or in qtgui_sink_ is flat noise with the peak
of the offset dc in the center.

He intentado diferentes  niveles de ganancia pero no hay cambios en el
spectro


however with gqrx or in windows with the analyzer of pavsa the hackrf
behaves perfectly

This is my hackrf.

hackrf_info version: 2018.01.1
libhackrf version: 2018.01.1 (0.5)
Found HackRF
Index: 0
Serial number: a06063c82566ad5f
Board ID Number: 2 (HackRF One)
Firmware Version: 2018.01.1 (API: 1.02)
Part ID Number: 0xa000cb3c 0x00474f57
