Open question does anyone know how i would go about removing the noise the main switching fet is making.

I have been reading this:

Page2 is basically what I am seeing.

Also get the same ringing when the with the micro and radio power disabled.  So i am pretty sure its the fet.  That i confirmed when i ground its gate and the noise went away but so does my power supply so that is not a solution:)

Also if i am being stupid with the component choice let me know:) i don't mind being wrong.
