Right after I got my P2 I went ahead and installed the copper sheet under the P2's cover to improve the number of Satellites and it most definitely worked. Went from 6 or 7 up to 12 that quick. Seeing how I am waiting on my P3P to show up, I was wandering if this same modification would be feasible for the P3? Common sense would dictate that it would work but thought I would just throw this question out there and see what others think and if anyone has already made this modification to a P3.
