Hello SDR community,
I need some guidance into how vector manipulation works in GNU radio
companion.
Suppose I have the following MATLAB/Octave code:
Nf = 128;
Nt = 2^10;
F = zeros(Nt/2+1,1);
idxs= (1:round(Nt/Nf)/2:Nt/2)+1
phi = 2*pi*rand(Nf,1);
Did you install GNU radio by compiling source code or with a package
manager (apt)?
If you installed with a package manager then "sudo apt-get remove
" should remove it.
If you installed by compiling source you need to go back to
"/path/to/source/gnuradio/build" and type "sudo make uninstall"
I am running a server with Mint 19 and had none of these problems.
I followed this Ettus page (word for word) to build GNUradio and UHD from
source. (without pybombs?)

interface.

Yes Ron is right. I have compiled GNUradio 3.7.13.4 many times on various
Debian (Mint, Ubuntu) distros and never got such an error.
Armchair opinion: the error is some kind of code problem which makes no
sense because these developers are very good and check their work
aggressively before
The repos are outdated. I ran into the same problem when first getting
started too.
You need to compile both UHD and GNUradio from source to get the
versions you want.
Ettus has a great (very thorough) guide on how to do this.
This book is also a great starting point and reference.

Also, here is a fun visual way of getting an alternative understanding of
Fourier transforms.

Hello all,
I was wondering how the compiler option "-march=native" effects large FOOS
projects like GNU Radio.
There seems to be conflicting opinions online, ranging from "it's does
nothing" to "it can break code".
Would GNU Radio (and VOLK by extension) benefit from this compiler option

Our lab is using USRP N310's with an external frequency synth ($500), a TI
dev board splitting chip ($200?) and an external 10 MHz selenium clock

After paying for RF cables and a host server, we are roughly getting 1

I figured this out today. I used a handle_msg and simply connected a
message strobe to the 'junk' msg input. My custom block works as expected
now.

Hello everyone,
I have been attempting to make my own block that sends out a boolean
message if certain time related conditions are met.
I am unable to figure out why my block does not work. This seems to be the
line of interest:
*self.message_port_pub(pmt.intern('msg_out'), pmt.PMT_T)*

Hello everyone,
I have a situation where I want to save data to a binary file every 15
minutes or so.
We want to keep the same flow-graph running indefinitely to prevent
daughter-boards from being re-initialized. Thus, the obvious solution of
writing a script that runs and stops the flow graph
