For sure..
Now if I can convince the creator of modesdeco2 to add hackrf support I'm set.
Again well done to you guys, I just wish I knew about programming.
Great. The amp is not enabled by default, so that you don't cook your receiver in case you have some strong local sources.Expect a bit more code churn later tonight; I've almost got airspy support working too.On Sun, Jun 28, 2015 at 6:07 PM, Tom <[email protected]> wrote:Thanks,
Its running quite well so far, got 6 planes with these settings and 10 with the lna on.

Have only been running it for a few min so I cant compare yet.

Here it goes: https://github.com/itemir/dump1090_hackrf
I can get some reception from my window with the standard HackRF antenna.
Ilkers-MacBook-Pro:dump1090_hackrf itemir$ ./dump1090
No supported RTLSDR devices found.
HackRF successfully initialized (AMP Enable: 0, LNA Gain: 40, VGA Gain: 62).

Well done.
Look forward to trying this out.

Thanks! signed to unsigned conversion was the culprit. I first tested it with cox by converting the file and then tweaked my code to do that within the receive path.
I now have a working port of dump1090 to HackRF. I need to do some cleanup but as soon as done, will post it on GitHub and announce on this forum.On 6/27/15 1:29 PM, Donald Pupecki wrote:
I don't believe hackrf_transfer and rtl_sdr output in the same format. They are both 8 bit but the hackrf output is signed whereas the rtl output is unsigned.
If you get this working a hackrf please post the port on github or somewhere as that would be sweet.

Hello,
I am trying to add HackRF support to Salvatore Sanfilippo's dump1090 tool (https://github.com/antirez/dump1090) as a learning exercise. The tool was originally designed for RTL SDR devices. However, I can't seem to get this port to work.
To eliminate potential issues in my code, I simplified the troubleshooting steps. Here are the basic set of troubleshooting steps I am using:
Per tool's documentation, a data file can be captured with rtl_sdr utility in the following way:
rtl_sdr -f 1090000000 -s 2000000 -g 50 output.bin
Then you can pipe it into dump1090 like this:
dump1090 --ifile output.bin
I made an assumption that the HackRF equivalent of rtl_sdr command above would be the following:
hackrf_transfer -r output.bin -f 1090000000 -s 2000000 -p 0 -a 0 -l 40 -g 62
However, capturing packets with HackRF this way and piping them into dump1090 doesn't do anything. I have tried this sitting next to an airport and capturing packets while planes were landing and taking off. I don't have an RTL SDR dongle so I can't test the rtl_sdr command myself. It didn't make to sense to buy a RTL SDR device after HackRF but if I can't crack this, I am considering to buy one.
BTW, I also tried different gain settings, and sample rate of 8e6 with hackrf_transfer, no difference. That said, I never enabled amp_enable.
Would anyone know if rtl_sdr and hackrf_transfer capture the packets in the same way and format? Or do I need to do some kind of a conversion or translation in between the two to make them compatible?
Any help or idea will be appreciated.
P.S. I am aware of gr-air-modes for HackRF to decode ADS-B signals. My goal is to hack dump1090 and add HackRF support as a learning exercise.
Thanks,
Ilker
