Re: [Discuss-gnuradio] GFSK mod/demod does not work OK with wav file

Hi Fernando - Are there are errors / warnings / printouts happening in your GRC log window or in your terminal? Do you see `aU` getting printed, by chance? Also, just to be certain, your wavefile was recorded at 44.1kHz and not at something like 48kHz? Cheers, Ben On Fri, May 12, 2017 at 10:14

Hi Haile - Just to be clear, you are using a custom FPGA image, is that correct? Cheers, Ben On Thu, May 11, 2017 at 5:15 AM, Haile Berhe wrote: > Dear all, > I have been working on my X310 USRP with gnuradio just fine. But after I have > installed rfnoc modules and reload fpga images , the be

Re: [Discuss-gnuradio] Custom C++ blocks on E310

Hey Jessica - The SIGBUS you are receiving indicates that there is likely some funniness happening with memory addressing / access somewhere. Especially since your test flowgraph is so simple, using GDB to get a backtrace might point you to the offending code pretty quickly. For more details on ho

[Discuss-gnuradio] Implications of continuously un/muting tx stream

Hello! I'm trying to make a relay with a very long time division (rx for X seconds, tx for X seconds, repeat). Attached is my block diagram implementation. It's a bit cheeky, but it works (for just raw signal, no demodulation). Anyway, the flow graph's behavior works on my laptop, but my goal is

Hi Kartik - Thanks! I appreciate the description of how you will manage branches in your repository. This is really important work for GNU Radio's flowgraph UI, generally, and I'm excited to see your work this Summer. Happy Hacking! Cheers, Ben On Thu, May 11, 2017 at 5:23 PM, Kartik Patel wr

[Discuss-gnuradio] GFSK mod/demod does not work OK with wav file

I'm playing with a GFSK modulator demodulator from here: https://www.scribd.com/doc/254559988/Gaussian-Frequency-shift-Keying-With-GNU-Radio It works fine when transmitting a cosine, but when I transmit a audio signal (everything the same) it sounds bad, with noise and intermittent sound. Wh

Hi, I will try to decrease/increase the buffer size by using the " *set_max_output_buffer*" function (I don't know if I can, I will try it as soon as I have time). I am hoping that this will have some effect on the performance. Best, Ali ___ Discuss-gnu
