Hi Sam
If you do not get the XOSC/192 out on a GDO pin I would guess that your CC1101 has been damage. Can you change the radio and see if another one works?
What HW are you testing on? Have you made your own board or do you use our CC1101EM?
When starting a new design it is always a good idea to test SW and HW separately.
If you have written the SW yourself you should start by testing it on our HW. If this work you know that the SW is good and you can continue testing it on your own HW.
