I am working on a receiver panadapter application. I would like to use the QT GUI Sink Clicked freq variable parameter to control the receiver local oscillator to recenter the spectrum. I tried a simple test flow graph using GNU Radio version 3.7.13. When I click on the GUI Sink spectrum, the
Hi Marcus,
Thank you for your patience with my CtrlPort Performance Monitor problems. I
have been distracted by other projects and finally had time to try your
suggestion.

I want to use the CtrlPort Performance Monitor block to compare CPU usage of
several demodulator alternatives. I built GNU Radio version 3.7.12 using
PyBOMBS on Ubuntu 18.04. I added -DENABLE_PERFORMANCE_COUNTERS=ON to the
gnuradio.lwr recipe. I installed networkx, matplotlib, and

Thanks Kai! GNU Radio works perfectly on my MacBook.

Thank you for your comments Tom. I can make the QT GUI Slider height smaller
by changing the Python statement
from:
Qwt.QwtSlider(None, Qt.Qt.Horizontal, Qwt.QwtSlider.BottomScale,
Qwt.QwtSlider.BgSlot)
to:
Qwt.QwtSlider(None, Qt.Qt.Horizontal, Qwt.QwtSlider.NoScale,
Qwt.QwtSlider.BgSlot)
That may
I want to create a frequency spectrum display with a center frequency control
on a 800 x 480 LCD display. When I use the QT GUI Frequency Sink with a
slider underneath, the slider scale goes off the bottom of the screen. Is it
possible to reduce the height of the QT GUI Frequency display? The WX

Hi Jim,

However my favorite modules Sinks (osmocom Sink) and Sources (osmoscom
Source, RTL_SDR Source) are missed. I also would like to install Gqrx;
Could
you please show me a similar safe way to add the missed modules and gqrx ?

I have made many trials with the

Could this be a bug?

Hi Murat,
It was easy to install GNU Radio on the Raspberry Pi. I started with the
2014-01-07-wheezy-raspbian distribution.
Add the following entry to the /etc/apt/sources.list file:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib
non-free rpi
sudo apt-get update
sudo

shows the controls but the FFT display is blank. Does anyone know a fix for
this? The same flowgraph works fine with GNU Radio version 3.7.0 on my
MacBook running Ubuntu 13.10.

Jim Larsen
