I'm happy to test it for you Michael.
Want to give me a scenario?

Hi YiZiRui,
if this is really the case, this would constitute a bug - VOLK kernels
should work on 32bit machines too, although there might be
instructions that only appear on CPU's that support 64bit anyway.
However, nowadays it surprises me that peo

Hii Gnu Radio,
I have two installations of GR 3.65 and GR 3.7,
and I installed the project 'gr-ieee802-15-4' using
cmake -v -DCMAKE_INSTALL_PREFIX=~/gnuradio-3.7_install/
then make and make install anyways when trying to execute one of the python

I am trying to implement an OFDM transceiver, based on the existing GNU

How can I update the "occupied_carriers" mapping (turn on/off carriers)

Quick question: can a message port name be any valid PMT type? Or does it have
to be a string converted to a symbol?

Thanks Bastian,
In another machine I tried to install it with GR 3.7,
but in the cmake I got this error:
CMake Error at
~/gnuradio-3.7_install/lib64/cmake/gnuradio/GnuradioConfig.cmake:29 (list):
list sub-command INSERT requires at least three arguments.

Does it work on the first machine now?

Dear community,
Every now and then, when I execute my GNU Radio program, I get the
following error. Has someone seen this before? It looks like a buffer access
problem, but I’m not sure why it happens on and off

Is there way to manually scale the intensity of the QT waterfall sink, in other
words, set the dynamic range and reference level like the WX sink?
Adjusting the time axis with the scroll wheel alters the intensity axis, but
the actual color values don't change.
Thanks,
