If R5 is connected to LADJ then you may be right. Just remember the max voltage of 3 any place on the LINX.
Another way to get maximum distance from any radio is to use a good antenna. I doubt the , as we call them here "duckie" that is on the Parallax is very good. Most duckies are not very good for for distance.
A quarter wave with ground plane or a half wave will work the best for distance at any power.
I think dhouston has antenna info on his web site. Or google for a ham radio site for more info. The antenna is half of the radio in terms of performance.
