Re: [Discuss-gnuradio] Python Tutorial for MAC OS 10.12

Hello Michael, Thank you for the quick response, I think you are rigth, i need to clarify better my problem, i started from scratch the Tutorial, and i placed all blocks according to the Tutorial. After that i clicked on "generate the flowgraph". Once i did this in the folder where the GRC

Re: [Discuss-gnuradio] Pay You $$$ to Mentor Me - Tx OFDM 64 QAM and Rx Measure Error Vector Magnitude

HI IFly88, I don't fully understand your requirements – on one hand, you just say "I just want OFDM with 15 kHz subcarrier spacing and QAM/QPSK inside", on the other hand you mention LTE: an arbitrary OFDM signal with the right subcarrier spacing and constellation mapping does not constitute a

[Discuss-gnuradio] osmocom_fft

Hello, It's been a while since I was able to use gnuradio due to getting a son, but I've finally found some time to reinstall everything using Pybombs. I got almost everything to work, even fosphor. The only thing that gives me issues is osmocom_fft. Here is the traceback: Traceback (most

[Discuss-gnuradio] Python Tutorial for MAC OS 10.12

Hello everyone, Is mi first time here, and i am just learning about how to work with GNURadio on MAC OS. I am following this tutorial: https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python And when i reach the section 3.1.5, i rewrite the code and save it on Python, but

Re: [Discuss-gnuradio] Python Tutorial for MAC OS 10.12

Hi Luis Felipe - So section 3.1.5 is meant to show you some of the functionality of GRC and Python scripting. GRC is used as the primary means to create the flowgraph visually, and then to generate a Python script that can be executed. In this specific case, the tutorial is asking you to also edit

Re: [Discuss-gnuradio] Python Tutorial for MAC OS 10.12

Hi Luis Felipe - Nice to hear from another MacOS X user of GNU Radio; there are actually quite a few of us "out there"... Maybe you can clarify what you mean by "goes back to the original". Step 3.1.5 has you modify the GRC flowgraph, which will in turn generate an updated Python script; you view

[Discuss-gnuradio] New GR-SQL Module

Hi everyone, Back from GRCon2017 (one of the best conferences I've been to) and had some time for some more module development. During the conference in one of the working sessions there was a suggestion for a module that would allow you to query really large IQ files with a SQL-like syntax.

Re: [Discuss-gnuradio] Python Tutorial for MAC OS 10.12

Hi Luis Felipe - OK; thanks for clarifying. When you click the button "generate the flowgraph", GRC creates the Python file -- overwriting anything that might be there already. So, any changes to the Python file are lost when you have GRC generate the flowgraph. Note that, at the very end of

Hello everyone, Thanks for the responses, they are helpful. Michael, I get o tried to do that "python file" manually, but It did not work. Maybe I am doing it wrong. I opened opened a terminal in the folder where the python file is and I placed the manual commands that are on the tutorial, but

Hello Piotr, hmm, that certainly doesn't look like code I have touched, and I can't say I have seen that error before either. I'm running Arch Linux (Python 3.6.2), hope that helps! :) Best regards, Håkon Vågsether On Sun, Sep 24, 2017 at 4:27 PM, Piotr Krysik wrote: > W dniu

Hi all, I have updated my blog for my next to last week, providing a demonstration of my recent additions. The most important changes are the build options, my yaml_blocks_python branch and last but not least, the ability to generate QT flowgraphs in C++ with GRC! :) You can read more at:

I want to create a spread of 15khz sub carriers ( like LTE ) that fills up bandwidth of 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, and 20 MHz ( like LTE bandwidths ). In the 1.4 MHz block there are 72 15 khz subcarriers, 180 in a 3 MHz block, 300 in a 5 MHz, 600 in a 10 MHz, 900 in a 15 MHz, and
