Re: [Discuss-gnuradio] Multipath Fading

Hi Ritvik, to analyze whether you're seeing attenuation, you should actually compare the power of a un-faded and the faded version of a signal with a *single* QT sink. You can configure that sink to have two inputs. Your dB-scaled FFT display hardly lends itself to comparing powers. To test the

[Discuss-gnuradio] File Sink Behavior

I'm testing a radio by sending known data through from a file source, and file sinking the data at the end of the Tx/Rx loopback chain. I'm getting very specific erratic behavior with the contents of the output file. One of two things happens. First, the output data is perfect. Second, the first

Re: [Discuss-gnuradio] points in scope sink are missing when zooming in and out

Hi Jeon, sorry, I really can't reproduce that. Can you provide a minimal flowgraph that we can use to test? Generally, GNU Radio slowly moves away from WX towards QT, so if that's an option, use QT. Best regards, Marcus On 05/08/2015 02:36 PM, Jeon wrote: I am using WX. I miss some details in

Re: [Discuss-gnuradio] points in scope sink are missing when zooming in and out

I am using WX. I miss some details in the previous post. It doesn't happen when I hit zoom in and out one or two times. It happens after hitting zoom in and out 4, 5, 6, ... times. Not sure exact value. Also, it seems the duration of each bits are unchanged. i.e., ten ones before zooming and

Re: [Discuss-gnuradio] E310 shutdown issue

I have used a variety of methods: shutdown -h now, I thought the screen socket might cause the hang up so I switched to shutdown -h 1 and ending the screen session. I tried poweroff next then shutdown -hP. Mark -Original Message- From: Philip Balister [mailto:phi...@balister.org]

Hi Jeon, is this QT or WX Gui? Greetings, Marcus On 05/08/2015 01:45 PM, Jeon wrote: For debugging or other purposes, sometimes I use time domain scope sink. When I zoom in and out, points in the scope are missing. For instance, flow graph generates a stream:

[Discuss-gnuradio] I Q samples in a source module

My source modules has 16-bit I Q samples that are interleaved: I,Q,I,Q,I,Q... as signed 16 bit values. I generate 512 pairs at a time in my work function (C++). I set noutput_items to 512 and copy I and Q out 512 times to the output_items variable in the work function. Is this the correct

For debugging or other purposes, sometimes I use time domain scope sink. When I zoom in and out, points in the scope are missing. For instance, flow graph generates a stream: 11001100 (ten ones and zereos are repeating) After hitting buttons zooming in and out,

Hi, I've been trying the instructions in the wiki with ubuntu 15.04 and gcc 4.8 (4.9 also gave me problems). I got the following error checking out the android branch from git:// git.gnuradio.org/gnuradio.git error: The following untracked working tree files would be overwritten by checkout:
