Almost everything on the 4 band controller is a surface mount IC. I have posted images on my website alone with my range theories.

The range on my 4 band isn’t so bad it’s not as good as the gen 1 controllers but a lot better then the gen 3. From what I can see, there is no eay to esily boost the power on the 4 band controller. At least it is not as obvious as that of the gen 2 or 3 controllers.
