Re: Messages into two blocks: Message order & timing guaranteed?

Hi Johannes, Thanks. It's not exactly a TDD system but I assume in terms of timing similar, yes. In a TDD system I am most concerned that transmitted data is perfectly timed. In my case, I need both, transmitted data and received data to be perfectly time aligned with each other. Think of my sys

Javier, It can be very confusing! First, you need to work through every step of the https://wiki.gnuradio.org/index.php/Guided_Tutorial_PSK_Demodulation (QPSK) tutorial. It uses 2 bit symbols and 4 samples per symbol. The BPSK tutorial uses 1 bit symbols and 4 samples per symbol. The differe

Derek, Sid, Sid, Thanks. Looks like a good starting-point. thx :-) Derek, That is true, but I want to focus the workshop in GNU Radio itself, not on how-to-install-GNU-Radio :-) So I prefer something where everything is already pre-installed and that the user just needs to do two things

Re: Ho to use Limesdr and rtl dongles with GNURadio 3.8.2

2020-08-27 Thread Paul Boven
Hi Christophe, This is unfortunately a known problem. The way GNU Radio was packaged in Ubuntu 20.04 is (to me) a bit odd, with the version number as part of the package name for most of the libraries. If you install GR from the PPA, you will now get version 3.8.2, which is great. This will

Hi I recently switched my computer to Ubuntu 20.04 and installed GNURadio 3.8.2.0 from ppa (http://ppa.launchpad.net/gnuradio/gnuradio-releases/ubuntu). Version 3.8.2 is the latest in this PPA and is installed by default. I also installed gr-osmosdr gr-limes

That's a issue with gr-iio's grc yaml files if that's the case. There are a few forks of gr-iio around at the moment, something that's very close to being permanently fixed. You should be able to find a iio_pluto_sink.block.yml file that will make the Pluto Sink block appear in GRC. Possibly th

Hi Kristoff, There are a bunch of ones around which have GNU Radio pre-installed, but my most common answer remains using the vanilla Ubuntu 20.04 live image and installing GNU Radio and any needed OOT modules from the Software library. Clicking this link will open up the install page for GN
