Hello Cinaed,
Thank you for the response,
I have detailed your Flowgraph, and I placed a "QT GUI Constellation Sink"
after the chunks to symbols block, and what I found is that the modulation
part only modulates in B-PSK, and this is beacuse you set it in the
"Chunks to symbol block" with a

Hello Cinaed,
Thank you so much for all the work in the BER, i tested both of the
flowgraphs and they are very accurate regarding the BER measurements, i
have a couple of questions if you don´t mind:
1- In the latest flowgraph you sent (my-ber-test.grc from Jan 25th) how do
you change the
It bothered me that the random source wasn't working.
So I took at it again last night and discovered I needed to unpack a bit
from the random source stream.
Using the random source, the following work:
BPSK
QPSK
8PSK
16QAM
using the pull down menu.
There is, however, one caveat: for
Okay, I was really trying to get you do a BER calculation just once -
without getting distracted by QT.
If you look at the output of the random number generator, it's output
appears to be unsigned bytes.
But the output of Constellation decoder, appears to be signed bytes.
At the BER inputs,
Hello Cinaed and all,
Thanks for the response.
Mainly I want to change the modulation directly while running the flowgraph
(either by QT GUI Chooser or other switch), without having others in
parallel for future control systems implementations.´
I don´t know if you have any ideas or guidelines

Hello Cinaed, Discussion List,
Once again thank you for the response,
Please believe me that i have gone through tutorials, and i have understood
that in the python Top block i could enable/disable blocks, i also went
through this specific one for modulations:

Hello Cinaed,
Thank you for the quick response,
I look at your flowgraph, and i appreciate al the corrections you told me.
I must just say that i was guiding myself through the examples that are
under the folder digital when you install GNU Radio.
I took your model, and did some changes to
