Hi

I think that I broke something. My HackRF is about 10dB more deaf then others and I would like to solve it.

Does anybody have the schematics of the hackRF or knows where I can find them or has an idea what my problem is?

Thanks

RTL-SDR.com reader Syed Ghazanfar Ali Shah Bukhari from the Frequency Allocation Board in Pakistan recently emailed us to let us know a trick he’s found which lets you combine the bandwidths of two HackRF software defined radios in GNU Radio. Syed’s program is based on Oliver’s flowgraph that we posted previously, which was used to combine …

HALP!
I am on the fence with the HackRF.
When I read about people actually USING it, it all seems positive, but when I read reviews/comparisons, not so much.

One the one hand, I have heard that it's noisy, and the fact that it's ADC is 8bit is a bummer.
On the other hand it's only $300 (well $420 once you get the shielding, hamitup, etc) supports transmit, and my usage really doesn't need more than 8bit, so I should just get one. I guess.

I kind of feel like just getting a good, solid receive only device until a "better" transmit comes out in the the same price range, but I don't see anything on the horizon.
I could go with the bladeRF (transmit, 12bit) but the price is just more than I want to pay.

I actually like the hackRF a lot, and I'm not saying anything negative about Michael Ossmann, he did a great job and continues to offer so much to the SDR community which alone makes me want to buy a hackRF to support him and his efforts.

Anyway, any comments, rants, or bitch slapping of any sort would be productive in helping me decide. :)

It depends on what you're after. HackRF is a good, well-priced general purpose bit of equipment. If you need something that is specifically good in other areas then you don't want a HackRF, you want something more specialised. But at the same time you'll lose out on the other general things that HackRF does, like TX, or wide bandwidth, etc.

For me, I just wanted something for screwing around with and learning from, so it's perfect. If I have a specific use-case that the HackRF can't achieve, I'll get something for that.

Recently I got my first MS computer in about a decade. Its the MS surface pro 4. It's honestly a nice computer. I use it with my HackRF and wanted to duplicate my Macbook enclosure for the MS Surface. So here is my 3d printed enclosure.

Thought I would share :)

This looks promising. From what I can tell you need SoapyHackRF and I'll include that in the next post.

Mike Ossmann looks at the Chaos Communication Camp Rad10 badge - based on the HackRF
My First Look at rad1o Badge. Posted at: 11 August 2015 08:36 by Michael Ossmann. Over the next several days, thousands of hackers will gather at the Chaos Communication Camp in Germany. An electronic badge for the event is being prepared, and it is based on my design for HackRF One!

Kalibrate, or kal, can scan for GSM base stations in a given frequency band and can use those GSM base stations to calculate the local oscillator frequency offset.

I've used these commands to get it installed on RPi2

git clone https://github.com/asdil12/kalibrate-rtl.git
git checkout arm_memory
cd kalibrate-rtl
sudo ./bootstrap
sudo ./configure
sudo make
sudo make install


if you have a RPi (not 2) you can use this image: http://garethhayes.net/rtl-sdr-raspberry-pi-image/

Yesterday when I was experimenting with making a doorbell ring, I had a point where I was getting no results, so I made an FM transmitter like yours to test with. However, it turned out just dropping the audio sink in would listen to my laptop's microphone, which went through gnuradio, out the hackrf, into the rtlsdr, into gqrx, and out the laptop speakers. Caused some unexpected effects but worked :)

If anyone is using Gentoo, I'm currently working on an overlay for GNURadio and many of its blocks/utils. Right now it's local-only but I'll probably try to put it on Github soon if there's any interest. It's absolutely nothing special as I'm still learning the ebuild structure, etc. but so far it groups a lot of the packages together under "gr-meta" so that most of the collection can be installed all at once. I'll hopefully have an update later today after I've gotten most of the dependencies, etc. sorted out.

I am using Pentoo. It doesn't provide all the available tools(like a lot of those "gr-" modules), hence my overlay.

Anyone doing passive radar?
If so, I would like to know about your setup.

In particular, I'm curious to know how much i/q data is ingested, and if anyone is working on code to display parsed data in a human readable form.(2d or even 3d display).
I've seen some pretty sick python scripts that people have thrown together.

X2 chip I'm told is 65USD. Have to figure out your own board though.

PothosSDR. Very nice.  "The Pothos SDR development environment makes it easy for Linux and windows users to start exploring and developing with common SDR hardware and software without the hassle of downloading a building dozens of software packages."

Also has a GnuRadio toolkit for signal processing support.

This lets you use CubicSDR with HackRF. I think this is required for Pothos(which I'll post shortly as well)

Hi all, is it possible to use the hackrf one as rtlsdr or any dabstick? I mean kaffeine or dab-j-receiver wants a dabstick, and if just a hackrf is around it should just do. Any thoughts?

+Robert Dady Raw I/Q samples from the HackRF is the normal expected behavior from applications that use libhackrf. Television software can't do anything with that data, though. They expect MPEG streams. If you want to use the HackRF to watch television, you need to adapt a software based DVB-T implementation like https://github.com/BogdanDIA/gr-dvbt. It requires a lot of processing power and isn't very practical unless you're interested in the details academically.

Bought a very cheap wireless doorbell to experiment with transmitting from my +HackRF Blue. Took a few goes, but succeeded in the end making it ring from the computer. Will have to do a proper writeup of the process some time soon.
