Hackfest at ESA ESTEC (Noordwejk, NL)

Hello folks, the hackfest at ESA, kindly organized by Andrej Rode, is well underway and we're seeing very interesting progress so far: * a workgroup (packaging) is looking into getting the OOT ecosystem into shape: Infrastructure to build binary packages (.deb for now) to go with our GNU Radio re

gr version hell gets bigger and bigger...

Hi out there, only a common remark :) I am using gnuradio for around six or seven years now, and such issues were always present, but I never experienced them in the extent like nowadays. More and more I am trapped in version conflicts. Only one simple example, for being able to use gnuradio wit

Ubuntu 18.04 LTS QtGUI issues

I have a user of my spectro_radiometer app who is having problems installing it on Ubuntu 18.04 LTS. He installed gnuradio from the repos, then when using grcc -d on the .grc file, gets: Block key "variable_qtgui_label" not found Block key "variable_qtgui_range" not found Block key "variable

Re: Ubuntu 18.04 LTS QtGUI issues

Looks like gr-qtgui wasn't installed. How did the user install GR? On Wed, Jan 29, 2020 at 1:22 PM Marcus D. Leech wrote: > I have a user of my spectro_radiometer app who is having problems > installing it on Ubuntu 18.04 LTS. > > He installed gnuradio from the repos, then when using grcc -d on

Using apt-get install Gnuradio. That package includes everything. Sent from my iPhone > On Jan 29, 2020, at 1:23 PM, Michael Dickens > wrote: > >  > Looks like gr-qtgui wasn't installed. How did the user install GR? > >> On Wed, Jan 29, 2020 at 1:22 PM Marcus D. Leech >> wrote: >> I hav

Re: Ubuntu 18.04 LTS QtGUI issues

Interesting. I really have no idea what's going on there. Using a package install should just work. Are there maybe multiple GR installs & somehow they are being mixed-between -- maybe by some odd shell environment settings? - MLD On Wed, Jan 29, 2020 at 1:35 PM Marcus D Leech wrote: > Using apt

Yup. If I were sitting in front of his machine, I could figure it out probably. But he’s in Guatemala. Sent from my iPhone > On Jan 29, 2020, at 1:50 PM, Michael Dickens > wrote: > >  > Interesting. I really have no idea what's going on there. Using a package > install should just work.

Re: LimeSDR USB parameter help

hi, Christophe Seguinot i have downloaded your .grc file. i ran it on my laptop with changing audio sink to 44.1, 32, 24. Of course, freq is a fm radio in my area. But i still saw aUaUaU. i heard noise only. my info is: hardware: Limesdr USB OS: ubuntu18.04 gnuradio: 3.8.0.0 gr-limesdr:

Re: Recommendation for high sample rate receiver?

Hi A high sample rate for such ns times of arrival resolution is impractical. Same holds for high SNR and longer times of measurement. GPS and most other high resolution positioning systems stitch the information together from the signal time of arrival with the carrier phase of arrival. Since c

Re: Recommendation for high sample rate receiver?

To whom it may concern: It is already well-discussed, but I would like to add a few points: -If you absolutely want to have a such receiver (it's pretty meaningless, as discussed already, but if you still want to), then you can grab a digital oscilloscope or a similar hardware and attach a RF f

Re: Recommendation for high sample rate receiver?

To whom it may concern: Forgot to mention: There is a Wikipedia article, listing SDR receivers with various capabilities ( https://en.wikipedia.org/wiki/List_of_software-defined_radios ). There's also something called OneRadio ( http://www.oneradiocorp.com/ ). I saw an actual build of OneRadio

Capture Finite Samples

Hello everyone, I'm trying to capture a user specified number of samples from 3 USRP X300's. To do this I found the finite_acquisition_v function. The problem is it behaves very irregularly, so much so that I can't figure out the right way to use it. It seems that I have to call it once with a bi
