Hi,

I need more information here, I cant say what is the problem just form that picture. Reasons for poor RX performance can be form crystal noise or poorly designed switching. 

The according to the datasheet of the SKY66112_11 and what i am able to view of the schematic in the picture there does not seem to be any error.

Regards,
Jonathan
