Hey all,
I have been flailing away, and failing, at getting the qt waterfall sink
time axis to be scaled properly.
Using gnuradio 3.8.2.0-3 on Manjaro
One thing I found looking at the source code for the waterfall sink is that
despite the option to set an update period the block always uses 10 se
I am having difficulty using gr::filter::firdes in my OOT cpp block.
(Trying to use code block in notorious webmail editor for gmail, sorry if
this gets a little garbled)
I am calling my setter function as follows...
```cpp
set_filter( 31.25f, 50.0f, 96.0f );
```
And this is the setter func

Hello list,
I have been unable to get any OOT module blocks to run in GRC.
I initially was using a VirtualBox Manjaro (via Architect) with GNURadio
3.9 and with some finding missing packages (cmake, swig, boost, boost-libs
maybe some others Ive forgotten) was able to get gr_modtool created blocks
Hello,
New machine with new Kubuntu 15 install, new build-gnuradio install on that
system.
Had some install issues with a prereq lib that required a force-overwrite
to a deb archive. But seemed to progress normally after that was fixed.
Also had a warning regarding a missing libzmqt(?) dev packag
The new GRC theme system using qss files looks pretty neat and seems very
user configurable. Thanks.
To use this, with my build-gnuradio installed setup, I had to create a new
file under my home user folder at /home/me/.gnuradio/config.conf and I had
to add the following to that file.
[QTGUI]
qss
DESTINATION share/gnuradio/grc/blocks
Thanks,
all that worked great now.

Hello again,
I tried to add a C++ noblock to my OOT module. In this particular case I
wanted to provide a reusable "n of m" counter class (for non-signal stuff
to count) in C++ code that I could use within various C++ blocks in the
module. And I did not know of a better way to manage that with the
Is there a way from GRC to set some of the 'extra' parameters in the QT GUI's?
For example, say I want to enable auto-scaling, or set the FFT averaging, or
set signal colors or names for the legend.
I understand how to do all that after starting the flowgraph, but it takes some
time and it only p

Trying to get my OOT block to accept a vector of floats for filter taps.
I used a couple in-tree blocks (mostly ofdm_carier_allocator and
fir_interpolator) for a quick reference. And I have fir interp/decim in my
flowgraph and they have no issues at runtime. The flowgraph ran fine with my

I am getting a link error when making my Out-of-Tree module.
I apologize in advance for the length of this, my first post to this list. I
get the daily 'digest' version.
This Out of Tree module was done with gr_modtool and cmake following the
