Hi,
To properly explain the issue I'm facing, I recorded a video showing
Oscilloscope waveforms.

The gnuradio flowgraph is here:

Hi! Any pointers to where I can start debugging this?
Maybe run gnuradio-companion in debug mode?
Do more simpler tests?
Any other suggestions?
I have a HackRF One and will try the exact same comparison there too ...

And, if I try the attach gnuradio file, which is just a constant source of
value '1' going to the limesdr sink block, I actually see a sine-ish wave
without the glitchy behavior.

Perhaps OT, how good/bad close/far are these kinds of noise generators to
AWGN?

Hi,
What would be the preferred method of installing gnuradio on OSX 10.15.7 on
Macbook Pro 2019 with support for limesdr via soapysdr.
I have two environments in linux (gnuradio 3.8 on ubuntu 18.04, and
gnuradio 3.10 on ubuntu 21.10) with soapysdr + limesdr which are working
well, but I am very
A gnuradio flowgraph reads values of some variables from a config file
(let's say default.conf). When variable values are changed, the config file
is updated accordingly.
There is a second config file called reset.conf, which contains "default"
values of these variables.
Is it possible to put a b
>From whatever looking around I could do, it does not seem like it is
possible without adding custom python code to a flowgraph.

Hi,
How should I go about modeling the distortion introduced by a class-B
amplifier stage that clips the signal when its value is below zero?
Example:
I want to combine two FM modulated signals, pass them through this "class-B
distorter", demodulate them, and analyze the quality of the signal pr

Hi,
I currently have a gnuradio flowgraph that requires high compute resources
and is running on a laptop with a high-end cpu which is connected to a
LimeSDR.
That LimeSDR is eventually connected to a RF PA and an antenna for
broadcast.
The limitation in this setup is that the laptop needs to be
Thanks, I tried a very basic example and was trying to monitor data rate
using nethogs with a different sample rate.
At a signal sample rate of 9.6MSPS, nethogs sees about 59MB/s of data. I
wonder if that could be improved in anyway, or whether the sample rate of
an actual wired lan connection mig
I wonder if it is currently possible to have the label of a GUI element
come from a variable in a config file.
For example, A QT GUI Range block's label is
str('Power: ' + ch_1_label)
Where ch_1_label is coming from a variable config block. However, when I
run the flowgraph I get the error
'Unbou
I fixed the error, but am still unable to update the label from the config
file.

Hi, This is my very first post to this mailing list, so hello to all. I am
a beginner in experimenting with gnuradio and sdr (hackrf-one). I am
working on an application where I want to take multiple audio input sources
and transmit multiple FM signals over one RF channel via the SDR. To this
end,
your computer.
