[Discuss-gnuradio] Programmatically determining which tab (tab widget) is selected

2016-06-17 Thread Dennis Glatting
Is there a way to connect a tab widget to a block such that the block knows which tab is selected?  Simply typing the widget's block id into the target block doesn't work. I get:  "Value "intc" cannot be evaluated:  name intc is not defined The tab widget's id is "intc". ___

Hi Simon, Yes, pulse audio is available for Mac OS however my reading of this is that the problem doesn't lay with GQRX or pulse audio. It is the original gf-fcd code which forms part of GNURadio that is causing the problem, at least from what I understand of it. From what I can see it all ha

Hi, Sometimes my computer acts up and displays Us on the output, meaning that there are underruns. However, this does not happen too often, but is a pain when I am running an automated trial because it freezes the entire program. Is there a way in python to tell whether a U is printed out and then

It appears to be barfing on the audio source in the link you provided. I don't know anything about OS X, but gqrx on Linux requires pulseaudio. Does pulseaudio exist for OS X? -- Cinaed On 06/17/2016 09:16 AM, Sean Sharkey wrote: > Hello All, > > > I’ve being trying to track down a problem,

Hi Berat, I might be wrong, but it appears to be an autotools problem, as it doesn't seem to find the aclocal. You can try running: sudo apt-get install autotools-dev sudo apt-get install automake maybe you'd have to install also aclocal via apt-get. I tried installing the gnss recipe via pybom

Hi Avinash, that's pretty much a basic OFDM question: You take the DFT of the input signal. Hence, the bins of the DFT are f_nyquist/l_fft spaced. Best regards, Marcus On 17.06.2016 17:57, avinash kalyanaraman wrote: > Thanks Marcus - that helps. > > Could you please let me know what's the ban

Not sure of which OS you're using but try either apt-get install automake or apt-get install autotools-dev It's possible you may be missing automake - but it's hard to say when cmake runs in an old build directory - cmake may just have it's knickers in a twist. Also, blow away the build di

Hello All, I’ve being trying to track down a problem, a programme crash, which occurs when trying to run GQRX with a FunCube dongle and which might possibly have its roots in GNURadio. In short it would appear that when the gr-fcd code was incorporated into GNURadio a couple of years ago it m
