[Discuss-gnuradio] Python Unit Tests Running Twice

I noticed that my Python unit tests were running twice. Using PyCharm's debugger I was able to figure out that the culprit is the following snippet from gr_unittest.py: # use the xmlrunner if we can write the the directory if(xmlrunner is not None): xmlrunner.run(suite) main()

Re: [Discuss-gnuradio] DVB-S2 Physical Layer Framer: Why outputs a zero after each sample?

The primary design decision was to use the FFT filter instead of the interpolating FIR filter for performance. The FFT filter is considerably faster, especially at the 100 taps used in the flow graph. However, (as far as I know) the FFT filter does not have an interpolation option, just

[Discuss-gnuradio] DVB-S2 Physical Layer Framer: Why outputs a zero after each sample?

Hi to all! Specially to Ron Economos! (and thanks for sharing your work) I was trying to understand the example *dvbs2_tx.grc* and, after putting graphical sinks after many blocks, I noticed that the one called "Physical Frame Layer" outputs one complex zero after each constellation point (see

Re: [Discuss-gnuradio] File source problem

One clue for you is already being printed out for you in the TX flowgraph image. Get rid of the throttle block. The RX time domain plot looks actually pretty healthy. It's showing a frequency offset, which is normal for unsynchronized devices. The constellation plot needs to happen after timing

I'm giving a copy of the email I just sent to Ettus Research. I think that it's been a hardware problem since the beginning but i'm waiting for their response. Check it out, maybe some of view have already seen this kind of bug

[Discuss-gnuradio] LimeSDR USB3.0 peripheral.

Hi All, Apologies to those who may have already seen this, but just wanted to share details of a new low cost SDR hardware platform that is currently crowdfunding, the LimeSDR. Main specifications are as follows: * 100kHz-3.8GHz 2x2 MIMO (LMS7002M) * Bandwidth: 61.44 MHz * Power Output (CW): up

Re: [Discuss-gnuradio] Re channel state information on rx_ofdm.grc

Hi Avinash, when you attach a "tag debug" after the "ofdm channel estimation" block, you'll see stream tags containing CSI estimates flying by. For more information on stream tags and how to handle them, I'd refer you to the Guided Tutorials [1], chapter 1-5. Best regards, Marcus [1]

Re: [Discuss-gnuradio] Transmitting changes a received value

Ah rookie mistake on my part! I went ahead and made the sample rates consistent (40.96k) across the schematic and an interesting thing happened. So I set these parameters: frequency to recover: 100Hz fft size: 4096 sample rate: 40.96k Sps to have a nice FFT bin number at 10 The interesting thing

You ought to be able to use PyQwt's compass widget: http://qwt.sourceforge.net/class_qwt_compass.html I used it for gr-air-modes and, while ugly, it does work. There's no integration into GRC so the Python to integrate the widget will, of course, be your responsibility. --n On Wed, Jun 15,

Hi Ben, Thanks for the feedback. 1. I have created a new repo for the Pybombs frontend on Gitlab [1] recently. During my weekly interaction sessions with Martin, we have decided to make the gui-frontend installable from pybombs-cli itself. Initially, I had plans on integrating the gui-frontend
