Hey Rich - There are some post-install tasks that should be run to handle these items. Have you tried this? http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioCompanion#Installing-Icons-Mime-Type-and-Menu-Items Cheers, Ben On Fri, Nov 7, 2014 at 9:28 AM, Richard Bell wrote: > It seems

[Discuss-gnuradio] QT GUI on low resolution display

2014-11-07 Thread Jim Larsen
I want to create a frequency spectrum display with a center frequency control on a 800 x 480 LCD display. When I use the QT GUI Frequency Sink with a slider underneath, the slider scale goes off the bottom of the screen. Is it possible to reduce the height of the QT GUI Frequency display? The WX GU

[Discuss-gnuradio] Packet sequence numbers

I'm using a vector-insert block to add a fixed-size header to a stream of interleaved short samples at a fixed interval, and then running it though stream-to-tagged-stream => tagged-stream-to-PDU => Socket-PDU to wrap it up in a UDP packet and send it out the network. The header consists of 28 s

[Discuss-gnuradio] Associate .grc with gnuradio-companion

2014-11-07 Thread Richard Bell
It seems that the pybomb install process doesn't associate .grc files with gnuradio-companion. I've installed it on two computers with that result now. I've done some reading on the issue, and I understand I have to do something with a .desktop file to get gnuradio-companion to be included in the '

Hi, In GRC, I need to switch back and forth (in real time) between two subroutines based on some conditional 'IF' statement. For example, 'after' some preset lapse of time. Is it possible to do that? Please note that I need the conditional switching to take place in real-time while the USRP is ru

So, following your idea, after waiting a larger period of time, passive scanning should "catch" my beacon right? (becouse when entering new area, or getting in range of unknown AP, there are no information to send direct probe request by mobile device). I think that mobile device is performing so

[Discuss-gnuradio] FIR filter Interpolation vs Resampler

2014-11-07 Thread Daniel Batista
Hi I derive the output of a signal, both to an Interpolating FIR filter and Rational Resampler (in parallel) and then I connect them to a Time Sink (with 2 inputs). I use the same interpolation factor for both blocks (interpolation = 4). I also use in taps the same rcc filter. In Time Sink plot
