Noncoherent FSK using 5421

I'm trying to generate a user bit pattern (not PN sequence which is found in most of the MT examples), modulate FSK on FGEN 5421 board.
Then from 5122 scope, FSK demoduate and recover the generated bits. However, I am having a difficulty in doing this. The recieved bits are all
junk.  I looked at the simulated FSK Transceiver and others, but there's no example that simply generates bits and receiving bits with FGEN and SCOPE.
Also, I couldn't find any non-coherent FSK examples.
 
Here's the specs:
Carrier Freq: 3MHz
Modulaton Index: 1
Symbol Rate: 64Kbps
MARK: +32KHz
SPACE:-32KHz
Modulation Scheme: FSK
 
I'm attaching the program that I've been working on.
Any help would be great. Thanks
