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 mine (attached my new file) but i still can´t get in the QT GUI to switch between different modulations, if i start with 8-QAM it does not switch to QPSK when i choose QPSK in the QT Chooser, i would appreciate if you can give me any ideas regarding this. Kind regards.
