How can I create a Hierarchical block with GNURadio.
In gnuradio-companion I'm using the audio source block as my input signal for the next blocks. All works almost fine. All works almost fine. The only little problem is that I'm getting the signal from my microphone (this is the normal behavior off course).
Getting Started with GNU Radio and RTL-SDR (on Backtrack) By Brad Antoniewicz. In this blog post I'll aim to get you at least partially familiar with Software Defined Radio, the Realtek RTL2832U chipset, and provide Backtrack 5 R2 setup and usage instructions so that you can easily get off to a good start.
Recently RTL-SDR.com reader ghostop14 wrote in to us and wanted to share his GNU Radio block and tutorial that shows how to get rid of the DC spike in GNU Radio. The DC spike is the annoying spike in the middle of the spectrum that appears no matter where you tune and shows up with almost all SDRs, such as the HackRF used by ghostop14. Software programs like SDRsharp and HDSDR have algorithms.
RTL-SDR is currently very popular topic on the Net. There are also many guides on how to use it on Windows and Linux too. But starting to use it myself I haven't found any guide that explains whole process from installing necessary drivers and software to building first simple receiver using GNU Radio which is the most capable software which could be used with RTL28xxU chips and that's what.
Worked examples in GNURadio Companion including a QPSK data modem. Worked example of a python GNURadio app. Working with SDR hardware such as the USRP. Worked example with RTL-Dongle. Custom Signal Processing in GNURadio. Worked example of how to write a GNURadio signal processing block. Generating block skeleton code. Populating the signal.
What has not changed is the fact that GNU Radio is centered around a very simple truth: Let the developers hack on DSP. Software interfaces are for humans, not the other way around. And so, compared to the later 3.7 releases, nothing has fundamentally modified the way one develops signal processing systems with GNU Radio: You write blocks, and.
My goal is to be able to call fast lock profiles from gnuradio - no problem if you want the profile number to be static, but if you try to swap the profile number via a variable it's almost impossible as none of the gnuradio variables or parameters allow strings, the update attribute block only allows strings.
