[Hackrf-dev] I only get flat noise in gnuradio
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 Thank you ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
[Hackrf-dev] Hardware recommendation for hackrf
I'm having overrun problems, especially from 8mhz of symbol rate.I was thinking about buying a more powerful computer, I currently have an Intel celeron J1900 4 cores at 2Ghz and a ssd . I have also tested an i3 and it seems that it is even worse. The funny thing is that the overrun occurs even with the cores working at 50 % so I find it hard to believe that it is a processor problem Best regards ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
Re: [Hackrf-dev] I only get flat noise in gnuradio
In the end the problem was in the Rf Gain control, it was too high Best Regards ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
[Hackrf-dev] How does the hackrf generate the signals?
I've been wanting to understand how an ofdm signal is generated for a while and I can't The hackrf generates similar signals but I also do not understand how it generates them. It seems impossible to generate 8000 carriers at the same time, therefore the only thing left is to generate them sequentially(to sample), generating a point and passing to the next frequency , thus until 8K and then go back to the beginning and go the same way.The trick would be to do it so fast that it is not noticeable to say it in any way Thank you ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
[Hackrf-dev] Hackrf and oscilloscope
Hello, I would like to be able to analyze a COFDM carrier with the oscilloscope (100mhz) and I have thought that perhaps in the hackrf there may be a position where it can be done with the appropriate software Thanks in advance ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
