Hi Guys,

Thank you very much for all your replies. It has been a great help. 

Thanks for the link Gunther. I searched EMC not EMI hence I didn't find that thread. 

My current design does have bypass capacitors to the power supply pins of the SX52 but they are not all individually connected. Two are individually connected while the other two are bypassed by one capacitor. A must fix in the design!  

The board is currently a two layer design (with the majority of the bottom layer GND). 
Looks as though we may have to update the board design and go with a 4 layer option. 

Thanks Paul for the interface design termination link. As I am new to this pcb routing all this information is great. 

Thanks steve for all your information too.

Once again I would like to thank all you guys for helping me out with the problem. Thanks, I am off to fix up my PCB and get a new one run. 

Best regards

Stolzie
