Unable to get HackRF One working

[Allasso]

Steps to reproduce

Install gnuradio, gr-osmosdr, hackrf, libhackrf-dev on Macos and Ubuntu Install gqrx on Macos Install antenna and connect USB on HackRF One For gnuradio-companion, create various flow graphs per Michael Ossman tutorial, gnuradio wiki, run flow graphs. For gqrx, open app, set for WBFM

Expected behaviour

[1]Rx light comes on. [2]FFT plot appears. [3]Set center frequency to known local FM station frequency and hear audio. [4]On 2.4 GHz band, see change in FFT levels where moving 2.4 GHz access point closer/farther from HackRF One

Actual behaviour

gqrx: [1] above happens [2] above happens [3] above does not happen (no audio but white noise, except at center frequency, where white noise is squelched, but no audio.) [4] does not happen (making signal stronger has no effect on FFT levels.)

gnuradio: [1] above happens [2] above happens on Macos, but no FFT plot on Ubuntu. [3] above does not happen (no audio but white noise.) [4] above does not happen (making signal stronger has no effect on FFT levels.)

Which antenna are you using? Do you have another antenna you could try, too?

[Allasso]

Interesting, I was just typing this out when your post came through.

After trying a dipole antenna rather than the ANT500, carefully adjusting settings, and using gqrx, I became aware that I am able to barely hear the most well-received FM station in my area. Note that I live in a remote area and it is a distant station, however I was judging the results against what I am able hear on my vehicle's FM radio, where it comes in very clear and powerful.

Nonetheless, with the HackRF I am barely able to listen to the content among the white noise after cranking the audio gain up to 19.8 dB in gqrx. I compared this to my RTL-SDR dongle, using the same antenna, and while I still have to crank it up, the content is much louder and more listenable. (I also observe that with the HackRF I get -55 dBFS, whereas with the RTL-SDR I get -11 dBFS, although I don't know exactly how full-scale values are arrived at so don't know if that is a proper comparison.) Note I was using WFM(mono) setting as it worked the best.

So it would seem that the HackRF is working (?) however if it is, I would like to understand why a particular FM station is barely listenable on HackRF, when it comes in solid and clear on my FM radio. And also, while it isn't great on my RTL-SDR, it is so much better than the HackRF.

Note, the dipole I tried is tuned to the frequency of the referenced station (88.5 MHz, 63.5")

So is that expected behavior? Do commercially made radios just do a much better job of discriminating weaker signals?

Are you still experiencing this issue?

[straithe]

I'm going to close this as there hasn't been a response in a while, but please re-open this issue or open a new one if you still need assistance.

[roadmutt]

yes im still having the same issue is there somewhere i can just download a firmware flash and or the SD card image and then just transfer the files ive personally created to it afterwards
