[Discuss-gnuradio] File source problem

Hi

I have a problem.  On my first setup, I use 2 file source. The 1st file contains only '1' and the other only '0'. The 2 file sources go through a selector and end up in a CPFSK mod block. When I run this, switching from '1' to '0' makes the frequency drift from + to - FSK_deviation like it should do normally. Now, when I use a unique file source containing '1' and '0' (actually I wrote up the alphabet in a file) and I run this, this is what I get : https://www.dropbox.com/s/4tdswnmp79lj67c/unique_file_source.png?dl=0 . Any Idea why it's doing this. Is it the rate of transmission that does this, like if it was to fast ?

my setup : https://www.dropbox.com/s/snamjalklskfdzh/single_file.png?dl=0

Thank you
