  1. 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
  2. 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
  3. Hello everyone, I'm writing my first post in hope of shedding some light on rational resampling in FM radio. My idea was to get started with something easy to get me into the SDR programming and I chose FM radio. I have watched HAK5 SDR episode where the FM radio is built. I have also found similar graph on instructables (links below). I have tried to duplicate their graphs (with my own working frequencies), but without much success. My finished graphs produce loud cracking noise in my headphones. What I noticed, though, is what looks to me a strange discrepancy in the rational resampling and
  4. Not exactly a hacking question but I figured some of you guys might have had some first-hand experience with this tool. I'm asking because almost everything I've read about this triggers my pseudoscience alarm bells, but someone I work with who is in all other respects very smart and well educated is insisting that it's everything the sales pitch claims. Honestly, my gut feeling is that Steve Gibson is the techie equivalent of a cult leader, and if I could find any kind of corroboration for this damning dissection of his work, I'd be ready to dismiss SpinRite and associated products completel
  5. I've successfully installed it all but I'm not seeing the waterfall sink available or the WX GUI elements. Anyone have any ideas what I'm missing or who can point me in the right direction to try to get this going? Mystex
