Hello everyone.
Well, I tried to put a AGC block before the LPF and I changed some gain values
and I could receive some black and white moving images. I can't see it
perfectly like the example but I can appreciate shapes and with the hsync,
vdelay and hdelay sliders I hope to improve the movin
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);
Hi George - I haven't seen this error yet, but of course I'm just one
Mac UHD / GR user; I'll try testing my B210 for longer. In the meantime,
how is UHD & GR installed? If MacPorts, have you tried the "uhd-devel"
port? Sometimes it has fixes to the release. - MLD

I have been seeing this error regularly for a couple weeks. As I am running my
code, the error stops execution, on average, approximately every 10 minutes
(though, once or twice, I have received the error quickly in sequence). My code
is simple: I am reading in a recorded waveform (using File So

Hi Volker - You're welcome & so glad that we got the issue figured out! Which
reminds me that I never put together a PR for the changes that would give
programmers a clue that a hier2 block isn't meant to do actual "work". I'll add
that to my queue & try to get it in before GRCon ... Cheers! - M
Just to report the solution, as it me be usefull for others.
My block was an hier2 block. Hier2 blocks can't handle messages
directly, they only can serve as a proxy.
So I added a gr::block with no inputs and outputs ( yes, this is
possible, I did not know before ) that could handle the messa
Have you first registered the "clock" message port? This looks like
you're trying to set a handler for a message port that doesn't exist.
Also, when asking for help, it's usually very helpful to have your
*exact* code somewhere, not a reference to code that is /similar/.
Best regards,

Your GNU Radio was built without Thrift support.
You need to uninstall your GNU Radio, go back to the CMake step in
building it, and make sure all the requirements are met: in this case,
PyThrift and thrift, need to be installed probably. The CMake output
will tell you exactly what is missing.
