Hi Rob,
IMO the easiest way to setup GNURadio on Rpi is to use Archlinux [1]. You
could find platform specific installation instructions on the website
itself. Rpi-1 is underpowered and make sure that you are not running any
GUIs while running a flowgraph. Create your flowgraphs on a local machin
I installed the binary files

on a Win-8 machine succefullyon the default directory.
After running gnuradio-companion file from the Gnuradio 3.7
start menu folder I see a command window opening with message
"setting gnuradio environment",
then a couple of warnings of the
Yep, my bad on UHD, used to doing git builds and seeing 3.10. Cool yeah
gqrx would be the priority, baz is just a nice to have (and its a bit dated
as its all in WX which seems to be going the route of deprecation).
So for some feedback, I installed the binaries and everything seems to work
good. H
Hi Andy,
Just a quick update - I changed sps from 10 to 5 to repeat your trimming
procedure. Works like a charm. Certainly clear why you picked the 2nd preamble
copy and not the 1st..
as expected correlation is not as strong with decreasing sps (assuming unmod
preamble stays same size).
Lo
Some more information about the problem I have running the installed
version.
In the GNYRADIO command prompt shell I run python and then
>> from gnuradio import filter
and I get the following:
Traceback (most recent call last):

So the generic_mod() shifts the expected output by 50 samples to the right,
thus dropping 50 samples off the end. with this in mind, generating *two*
modulated vectors should do the trick:
- generate an untrimmed sequence 2 preambles long (seq1)
- generate another sequence 3 preambles long (seq
Hi Martin,
Thank you for getting back to me. I'm still a bit confused though. You are
saying that I need to call set_time_now() or set_time_unknown_pps() to sync
the clocks? So, simply connecting the MIMO cable between the two USRPs is
not sufficient for the clocks to be synced?
And as far as the
Achilleas,
To troubleshoot that problem:
1- download a program called "Dependency Walker", (www.*dependencywalker*
.com/)
2- Then with that, open the _filter_swig.pyd file located at C:\Program
Files\GNURadio-3.7\lib\site-packages\gnuradio\filter if you used the
default settings. It will give a
Hi Martin,
Thank you again for getting back to me. Let me elaborate on the process
that I am doing, and hopefully what I need will be clarified.
I have two USRPs connected via MIMO cable that are transmitting a sin wave
and one USRP receiving that sin wave.
I am trying to implement a system in w
