Re: [Discuss-gnuradio] fast parallel filtering

Hi Dirk, Thanks. Try the attached flowgraph. The pulse indicator output is a little crude at the moment (it needs some latching persistence for a human to read), but it does the job for a proof of concept. Note that in the future, you really do want to tune such the the SDR's center freq spike

A while back, we mentioned that we'd be moving the wiki to a new MediaWiki installation, and we're now aiming to finalize by the end of this Sunday. There's still a couple of tasks open, but the new wiki is already accessible at: http://wiki.gnuradio.org The content of the wiki was

Hi Andy, Very quickly collected some data off a different Tx. First at very close range, moving away, and then back again. It was quick and antenna was close to computer so perhaps quite noisy but should definitely have some strong pulses:

Re: [Discuss-gnuradio] Adding An Image File In GRC

Find the .xml file that describes the Qt label GRC block – it's very likely in gnuradio/gr-qtgui/grc – copy and modify it to your needs :) That way, you can have your own "image label". GNU Radio as project certainly wouldn't mind getting that new XML file as addition, neither :) Best regards,

Re: [Discuss-gnuradio] Adding An Image File In GRC

Hi Marcus, I already got the Qt Label to show an image by editing the python file that GRC creates. The problem is that if I want to use GRC "interactively" to change parameters/settings/etc. that's not available in the GUI I create then the python file is overwritten by GRC. So I was just

Re: [Discuss-gnuradio] Problem with underruns

Hi SverreTS, can you be more specific? Why do you think it's the problem? Can you give us a rough idea of what your program does? At which rates are you working, with which hardware, and so on. Best regards, Marcus On 03/16/2017 01:52 PM, Sverre Turter Sandvold wrote: > > Hi! > > > Need

Re: [Discuss-gnuradio] Adding An Image File In GRC

Hi Timothy, hm, basically, all the Qt GUI things are really Qt QWidgets and subclasses. The python file generated by GRC sets up the window and stuff. I think the quickest way of understanding how this all works together is making a small Qt-GUI-based flow graph, and diff'ing the python code

[Discuss-gnuradio] Adding An Image File In GRC

Hi, I am using GRC to create a flow graph that has a GUI and I'm looking for a way to add an image (a logo) to the GUI. Is there a way to use one of the Qt GUI widgets to add an image file? I know I can edit the python file created by GRC and add image file where I want but I think if I'm using

Re: [Discuss-gnuradio] Trouble compiling a program using GNU Radio with MSVC17 (was: Global namespace Errors with Complex and xlocNum)

Melvin, I would recommend using MSVC 2015, as I can verify that GNURadio builds fine with that, and the installation process for windows builds all dependencies with that to ensure consistency. That way you can at least rule out a compiler difference as the reasons. MSVC 2017 implements more of

Re: [Discuss-gnuradio] Gr-Inspector install errors

Installing headers in your home directory is very uncommon, that's also why cmake cannot find your installation there. Can you try to add that path to ./cmake/Modules/FindQwtPlot3D.cmake in line 8? Same goes for the library path in line 11, that you have to find out, too. On 16.03.2017 14:49,

Hi Paul, this message in *most* cases mean that qwtplot3d is not installed. Please make sure that these packages are installed: libqwtplot3d-qt4-0v5 libqwtplot3d-qt4-dev If this is the case, cmake cannot find your qwtplot3d installation. Can you please specify where you have installed qwtplot3d
