I did a simple test :

#include <stdio.h>

//unsigned long preamble = 0b111010101100110111011010010011100010;

for(int i = 0; i < noutput_items; i++)
{

}

{
printf("%u", out[x]);
printf(" ");
}
printf("\n\n");
consume_each (noutput_items);
// Tell runtime system how many output items we produced.
return noutput_items;
}
} /* namespace UAT */
} /* namespace gr */
I'm printing the input to the output directly and here is the results :
