  1. Hi there, I just got my pineapple nano the other day and I am trying to install dump1090 from the module menu but when I go to install the dependencies, it turns to yellow and says installing and then after a few seconds in goes back to red and says not installed. Any ideas?
  2. Hi, I am trying to do a replay attack on a remote control that I have. I can capture the signals fine but when I go to decode it the wave form looks very strange and very difficult to decode. The remote sends the same string 10 times. Maybe I'm missing something? I don't know. I would love some help from anyone and your answer would be greatly valued 🙂 Please see the following pictures Zoomed in The whole string zoomed out
  3. Hi Folk, I am using RTL-SDR to take dump of cell tower located in my region. Till now,I am able to take GSM incoming call dump which is working perfectly OK. Now, , my goal is to analyze GPRS connection initiation (GPRS attach) and corresponding signaling data. I have tried the scenario by switching OFF and then ON the mobile data but I couldn't see any packets related to GPRS. Is there something I am missing?
  4. Today, we released version 1.1 of SDRuno. The bandwidth for non SDRplay devices (e.g. RTL-SDR) has been extended to 2.5MHz. New features for the RSP include a calibrated power measurement facility, an SNR meter and automatic S-meter calibration. There are many additional improvements and fixes. To find out more, documentation can be found on http://www.sdrplay.com/docs/SDRplay_SDRuno_Release_Notes.pdf and the software is available to download from http://www.sdrplay.com/windows.html Many thanks to Paul Jones and Mike Ladd who have worked hard to get the new features documented in an updated version of the SDRuno Cookbook: http://www.nn4f.com/SDRuno-cookbook.pdf
  5. Hey All, I am now trying for weeks to setup Gnuradio Companion (3.7.5) with my RTL 2832U... I installed the RTL-SDR and the gr-osmosdr driver as described on Osmocom's Website. "rtl_test -t" works as well as "osmocom_fft -a rtl=0 -v -f 100e6 -s 2.4e6 -g 15" so I think those drivers are properly installed. Nevertheless no source blocks appear in Gnuradio Companion. So does anyone know what I did wrong or what I could try? Is there a fault in the cmake process of gr-osmosdr (cmake output: http://textuploader.com/651n )? Do I need those disabled components: Osmocom IQ Imbalance Correction, sysmocom OsmoSDR? By the way I am using Opensuse 13.2. It would be great if someone could help me. Thanks in advance! Marius
  6. So you've got the Radio bug? Want to learn more? http://www.hamtests.co.uk Covers both exams in USA and UK, tutorials and practise papers, so you can acquire a HAM license. Currently the cheap RTL-SDRs only receive data so this might not be for everyone. But if you want to learn everything about Radio this is the starting point.... a HAM license will permit you to transmit data/signals (restrictions apply). I think this is useful for all those budding Hack-RF users out there!
  7. Only about 60-65 % of the aircraft detected by ADS-B reveal their position. The ones that don't are military and private aircraft - business jets, small single-engined turboprops, and old aircraft lacking a GPS belonging to dubious airline companies. You probably came across the term 'MLAT' or 'multilateration' - a triangulation technique that can reveal the position of these aircraft. It requires a special setup (precise timing) of the ADS-B decoder software and a community of MLAT sharers. It might be a good idea to devote an HAK5 episode to this subject? Late March POTUS and his flying circus were in Brussels, Belgium. Obviously none of the aircraft revealed their position, only the ICAO hex address, callsign, and altitude. POTUS took into the air with a fleet of two US Marine Corps Sikorsky VH-3D Sea King (one of which was 'Marine One') and five US Army Sikorsky UH-60A Blackhawk helicopters (to visit the only American military cemetery in the country). The five Blackhawks revealed themselves on ADS-B Mode S, but the two US Marine choppers went a step further - one was invisible altogether, and in the second one its ICAO hex address had been changed to the non-existing '000001', but they forgot to suppress the altitude, hovering around 1,000 feet, revealing that it belonged to an helicopter. MLAT could unsneak the sneakers! I used PlanePlotter/RTL1090 and an RTL2832U/R820T dongle with the original antenna to track their movements. HAK5 fan from Belgium.
  8. Hey guys, I have been following along for a while and was happy to see some sdr action enter into the scene. I live in the north bay and have been watching some of the paging systems that are around here. Typically these are high power stations (some low band VHF, some High band VHF, some 400Mhz but mostly 800mhz) so getting a strong signal is easy with a stock rtl-sdr antenna. I am using PDW in windows (http://www.discriminator.nl/pdw/index-en.html). it may be worth while for members of this forum to check out. The amount of data that pours over the air from these is amazing. They send out data that isn't just local to the area but often is from other parts of the state. I have seen personal medical information get relayed from one medical staff to another during shift changes, status of equipment get sent out to techs (servers, HVAC, communication gear), Basketball game stats, Names of clients to be picked up by taxi services with contact numbers etc. I don't know if pagers are so old school they have been over looked or people just aren't interested in what they see but it seems to me that there is potential here. I would think that people smarter than me could write a program to sort this out by sender and start logging lots of info on a target. Check it out and see what you think. Keep the segments rolling, good stuff!
  9. First of all, I'd like to acknowledge that my recent interest in this type of research was born out of watching Darren's video interview with Renderman. So hat doffed, cheers guys! I found recently that a certain type of radio in some PC TV dongles (RTL2832U) can be used to watch more than free to air TV. I just ordered one for £7 on amazon, That's mindblowingly cheap.! The idea is that you use these USB devices to look / listen to the radio waves being broadcast around you within a range of frequencies. It seems that within these frequencies, all the good stuff happens. This is probably old news to a few of you, but that's cool, as I'd love to invite you all to discuss this here with me and everyone else here on why this is so cool and interesting, and perhaps help us all understand the possibilities of this cheap technology for learning and research purposes. http://www.youtube.com/watch?v=tqUPj852FFY Apart from all the applications that seem to be be here already for Windows and Linux (sorry OSX users!), there are other considerations too.. One of them would be fairly relevant to HAK5 in a way, as a need for the understanding of antennas is something a lot of us are interested in due to the pineapple. Of course there are plenty more devices which are more capable to do this, but at a cost increase. here is a couple of links that I have found wealthy in information. http://rtlsdr.org/ http://sdr.osmocom.org/trac/wiki/rtl-sdr http://hackaday.com/?s=sdr http://www.reddit.com/r/rtlsdr One more thing.... Someone made a way to use a DJ Controller as a way to control the interface of the software. http://www.dh1tw.de/powersdr-ui Now, that is awesome!
