  1. Hi, I am using a R820T2 DVB-T SDR (USB dongle from NooElec) and was wondering how I can measure the oscillation frequency (crystal) on the PCB. I've hooked up an oscilloscope. Ran an FM receiver program using Gnu Radio. Then I connected the probe of the oscilloscope to the XTALO and connected ground. However the program stops running when I measure and don't get any value. Any suggestions would be great!
  2. when i connected hackRF one on my computer is windows 10 pro can't detected automatically, and when i put hackRF one on DFU mode its detected as LPC (unknown Device) and when i open program zadig i see LPC can not find port Bulk-IN , interface (0) i install-rtlsdr and install SDRSharp.exe i see too many tutorial but i can't fix it please help me...?
  3. All the major wireless providers are slowing putting up 5G towers around my area and ever since a new tower was put up about 300 meters from my house I've been getting headaches and ringing in my ears. I've noticed this when I'm near any of the new low towers that have gone up. While scanning around trying to find out what is being sent out from those new towers I stumbled upon a signal that is very active and it seems to be coming from everywhere. I can pick it up on my handheld RF Explorer spectrum analyzer, RTL-SDR and BladeRF 2.0 A9 with various antennas. I've tried using my laptop and des
  4. V0.4 has been released! https://github.com/notpike/The-Fonz TX all commands as you would with the remote! Passive PIN discovery! Brute Force a command, loops threw all 256 PINs for a single command! Dank ass meme's! Booze, Chicks/Dudes and more! No piratical application but here's a script that uses the YSO (or any other CC1111 radio that uses RfCat) to emulate, brute force, and listen for the TouchTunes Jukebox remote transmissions. With this power you could skip songs, turn up/down the volume, or possibly add promotion credits for free songs. For
  5. Hi, I am trying to simply detect specific signal at specific frequency (as a start) then send signal from raspberry pi to arduino to trigger other command. From my research I found GRC as best option with hackRF one. I got the signal at monitor as below but as I am totally new in GRC I don’t know which blocks can detect the signal, I think the best way is to record the signal in file then detecting it in future using kind of comparison or by measuring the power. Please help me to choose appropriate blocks to achieve this result
  6. I only want to implement SMS via Cellular Broadcast. The idea is to send emergency broadcast messages to nearby cellular phones during emergency/disasters. What is the best SDR for this? If later I would like to use GSM phone to communicate with my rescue volunteers during emergency/disaster (aside from having SMS-CB functionality) what if the best SDR for this? Thanks
  7. Hej, I am trying to capture the FM frequencies using HackRF-one. I don't have the regular antenna, so I am using a different antenna (shown below). When I tried to record the FFT plot for the range of frequencies the receiver is able to capture, I obtained a plot as shown in the image below. I am a bit curious as to why the number of peaks and the height (length) of each peak is small. Can it be due to the antenna that I am using or the place where the SDR is operated? I am unable to receive any FM signal from the audio sink. If you have any ideas, please let me know. Sample rate :
  8. Hi, Starting of on a new project again, I'd be interested to learn more about analysing DECT communication through a HackRF. Is there any specific research that you think I should read up on? I've done my first steps with the hackrf: hacking the garagedoor, listening in on the babymonitor, ... now I'd like to start learning about DECT phones, but I'm 100% new to the subject.
  9. Hello, just wondering what folks have to say about the HackRF One units selling on eBay from China for $155, half the U.S. price. They all appear to have clear cases. Are these knockoffs, counterfeits, earlier model, or what? ... When i get a HackRF, i want it to be compatible with the PortaPack which i'll buy later.
  10. UPDATE: FIXED! After flashing the firmware on the hackrf to the latest, i forgot to the flash the newer CPLD image! GG. ------------------------------------------ Hey guys, just recently got a hackrf one and every station I tune into with SDR# sounds like chipmunks. I tried it on a fresh copy/install on my other windows 10 machine. Same results. I did upgrade the firmware on it to the latest from the github repo, without any results. I don't even know if I can trust this device or if it's fault because I literally can not get a decent answer or get pointed towards the poss
  11. Well I been getting the parts I got the coax cabling and my software radio is programmed and I got orbitron I just need to know what is the simplest antenna to make and if there are any decent tutorials with pictures now I don't got anything to really solder with so the simpler the design the better. If any one has had practice doing this with SDR let me know what you prefer to do. Also I plan to use my usb rubber ducky or my digispark to pull up the programs and set everything up for recording and automatically stop recording when pass is done. Also if it isn't much and the design is simple
  12. Hi, we have been engaged for a pentest and we would like to build a device that will allow us to 1) drop an SDR in the vicinity of the radio-controlled gate of our client 2) the SDR should be listening for keys constantly, but only record when there really is traffic. For this I think the device should constantly buffer the past say 15sec and store those 15sec only to file if they actually contain significant data. 3) remote control the device to monitor the number of collected samples, battery-level and potential discovery of the device by security personnel I was thinking
  13. I am wondering if it's practical to have an SDR transmitter small enough to fit in a person't pocket? The range doesn't need to be great (4 meters). I just need to transmit data at a rate of 1mbs from an untethered person (WiFi is not allowed) back to a base station. Any advice?
  14. I found out that if you make simple chains out of soda tabs its the perfect material to make a super bendable antenna that is super easy to store and when it done you can hook some non metal clips to the end to attach it too what ever you want. Now heres the best part if you don't got a soldering tool but hot glue this actually still works really well. Step 1. Strip some 50 ohm to 75 ohm coax cable and separate the shielding from the main cable and then when you done doing that put the cable off to the side and work on the chain. Step 2. Get soda tabs a lot of them and cut the ends o
  15. I thought this was cool I tried a few designs ended up botching them up but I found out just some simple rabbit ears extended to the right length plugged in via coax to my SDR was just enough to make this work even if for a little. I still got to remove the rabbit ears from tv antenna there used for to help increase the image quality then solder them to some coax but even when it was storming and I lost power I still got a image barely so this is a good start can't wait to make a video on it when I get it all clear and automated. Recent attempt turned out a little better managed to
  16. I'm going to dive down the rabbit hole and make my own personal base station using a BladeRF and YatesBTS. Has anyone else tried doing this? https://evilsocket.net/2016/03/31/how-to-build-your-own-rogue-gsm-bts-for-fun-and-profit/ (Not a good Tutorial) http://yatebts.com/
  17. I just purchased the SDR starter kit and I am trying to get it working on Windows 7. However, I cannot seem to find a driver package for it. Where might I locate it?
  18. Picture: Picture with wrong AM waves: Hello guys, I recieved and recorded an ASK_OOK signal from an auto remote key. But when I opened the wav file there wasn't the right wave forms( like in hak5 youtube show (reply attacks with yardstick one)). Please look at the pic. It would be very nice if someone can help me. Thanx JoJo
  19. Hello, I got Hackrf One, and am trying to work with it on my raspberry pi. I am constantly getting the following error: hackrf_info: symbol lookup error: hackrf_info: undefined symbol: hackrf_device_list I tried everything. First installing gnu-radio via apt-get and building hackrf master from source code, it didn't work. Then I removed gnu-radio and installed it by PyBombs which a lot of people recommended, but it didn't work as well. My last try was downloading the source codes of gnu-radio, osmosdr, iqbal by git clone and building them one by one which took days for gnu-radio
  20. Greetings, Recently, Mozilla sponsored an "art show" in NYC called "The Glass Room." The topic was privacy and data. One of the exhibits, by "Critical Engineering Working Group", had yagi-uda antennas passively scanning and collecting wifi enabled devices (phones, laptops, etc), that were looking to connect to a network. The data they were able to collect were things like device name, MAC address, preferred network list, and location. I want to recreate this exhibit. Ideally, the collected data would dump into a database where it could be interpreted later to establish a pattern. In the c
  21. I found an old UHF TV at the thrift store today and I thought to myself, what not a better way to learn how NTSC works! Simple stuff relay. If you want to transmit using a HackRF or BladeRF all you need to do is encode a .dat file with a Python script, run it threw GRC, and boom, Bob's your uncle! https://en.wikipedia.org/wiki/NTSC\ ttps://github.com/argilo/sdr-examples/tree/master/ntsc

    What is the difference between HackRF One, YARD Stick One, Ubertooth One, Software Defined Radio Mobile Kit?
  23. Has anyone ever got PyBOMBS to work in Ubuntu 16.04? After following the instructions from their GitHub page (https://github.com/gnuradio/pybombs/), both pip install and building from source, I'm running into the same error when trying to run gnuradio-companion. root@robot:/pybombs# pybombs run gnuradio-companion PyBOMBS - INFO - PyBOMBS Version 2.2.0 Traceback (most recent call last): File "/home/pike/prefix/bin/gnuradio-companion", line 99, in <module> run_main() File "/home/pike/prefix/bin/gnuradio-companion", line 87, in run_main from gnuradio.grc.main import ma
  24. For no real reason but to learn something new, I built Raspberry Pi tablet with Kali and a couple of RTL-SDR's for radio monitoring. I'm naming this computer, "Seirēn" because I think it's pretty and she's a killer lol. She's a work in progress being that I need to see how it runs two RTL's, give it touch screen capabilities, give it sound, and paint the thing some dumb color like pink... More to come!
  25. Hello, I need to implement WiFi 802.11 a/b/g/n/ac protocol with SDR at 470MHz. - Is it possible to implement WiFi at this frequency? - Is any existing implementations about it?
