Re: [Discuss-gnuradio] Simulation to compute BER of a Modulator/Demodulator Encoding/Decoding system

Also, in the Options block, I set it to "No GUI" so it would send the
output of the Message Debug to a terminal windows instead of the window
in the GRC.

Otherwise it overloads the GRC window.

Once you're convinced RS(223,255) is working, you can disable Message
Debug and enable the the QT GUI, and should be able to pipe the results
to some other block.
