Hi all, I use GNU Radio with a rtl-sdr dongle, which I tune to some frequency and then leave unattended for some hours. Sometimes, the reception just stops: in my flowgraph, I have some display sinks showing the waveform, and it remains still, like frozen. The GNU Radio interface is not frozen, tho
Can someone help to check whether these transmitter and receiver sliding
correlator channel sounder flowgraph are rightly configured. Thanks
Hi Akinyele,
GNU Radio companion has an "screen capture" function that allows you to
directly save **good** images of your flow graph. Also, your operating
system has the same. So, I'll respectfully point out that taking photos
with a camera is a complicated and not overly useful method to

Hi Fabien,
just so you know: We're aware and it's being worked on.
If you don't need controlport, then for now, disabling it (cmake
-DENABLE_GR_CTRLPORT=Off ...) would be a workaround.
Best regards,
Marcus

Hi James,
our software is called "GNU Radio", not just "GNU" :)
Anyway, the relevant python-click-plugins.lwr is most definitely not
empty, otherwise your Pybombs wouldn't be calling `yum info
python3-click-plugins` (it only knows to do that because of that recipe
file).
Can you run `yum info py
I'd presume there's something going wrong in the communication between
your PC and the dongle; maybe a USB packet goes missing, maybe the
dongle reboots for some reason, like unstable power supply. It's
probably wisest to fix that instead of building a watchdog around it.
If you really want to bu
Hi Fabien,
The blocks were built for use with the development version of GNU Radio
for a year ago, and as the OOT name states it's very much a work in
progress. The blocks function but I haven't updated them for the newest
development changes, nor have they been tested for actual 3.8 release
Regarding your first point, you're right, but I couldn't find the cause yet. At least I couldn't see anything useful in logs like dmesg or GNU Radio's console. Fortunately it doesn't happen very frequently, but it is very annoying when it does. About the second, I'll look into it. My understanding
Dear James,
CentOS 7 is really really old. I would say that you should ask
your customer or project leader to allow you to at least use CentOS 8.
You're just going to have a whole set of challenges and difficulties
using CentOS 7. Why create more unnecessary work for yourself?
Sincerely,

There are several options:
First, you can call

Oh, I was skipping past that; I was wrongly assuming you were using
CentOS 8.
Yeah, as Alex said, on CentOS 7, this will be cumbersome. If I was
forced to work on CentOS 7, I'd very much consider a podman or docker
container or simply a chroot to hold a CentOS 8 (or whatever more
modern, really) i

Thank you for creating a subject for the email. I completely forgot to fill in

In a previous message, Nicholas Bruce explained how to fill the "GUI Hints"

Hi,
I've been trying to create and use a rfnoc block for n310 within gnuradio 3.8
and uhd4.0. I first tried with pybombs but this doesn't not seem to work very
well and there is no default recipe that works. I then moved to manual install
from source and got something up using the maint-3.8 and
