Anybody added SAT to their Whites Surf PI

[6666]

Has anybody added SAT to their whites Surf PI ?

I have seen some rough drawings of the mod
but does anybody have a good drawing of the sat mod please
as I would like to learn how it works

Thanks

And where did this drawing with its hand-drawn changes originate anyway?
I've seen it reproduced again and again but am curious of the origin.

I thought Sat. on your Whites applied to a VLF detector,and not as per a PI detector that requires multiple channel for ground balance and retune functionality?
Maybe Ive missed something?Fill me in please?
