PLL for RF freq 1200MHz & prescaler 8: B=150 A=0ú22222222222

I have just finished the PLL stage and programmed the full code. When it runs with the com port view I get

I HCIiÛ3Wavebubble v1.0
PLL for RF freq 1200MHz & prescaler 8: B=150 A=0ú2222222222222222222222222222222222222222222222222222222222222222222222222222222222

And the two's continue. Also there is a clicking noise from the board.

Pressing space bar during or straight after start up gives no effect.

Anybody have any ideas of what could be wrong?

Thanks
