You will also find too - that the main "sense" for this section - it the 8V constant from the Radio itself - the AM "power" is set thru that reference - so what happens when you have radio that have envelope control - Stryker uses Q56 just like Galaxy.
So, as you try to raise up the regulated voltage to provide a voltage boost, the radio keeps itself about the same regulation "difference" between the on-board 8V and the Q56 sense control. You might see the radio swing backwards if people that I've seen abuse them - from attempting this voltage push and envelope control kicks it back down.
It's why there is the RWOB (Red Wire On Bottom - B. Ward) option many take to radios like this - quickest way to screw it up....
