Once at the posted coordinates you will see a pole with yellow numbers on a black background.
ABCD = the 4 digit number following the "P".
To determine the final coordinates do the following math:
N 43 51.[(B x 200) + (A x 90) + A + B]
W 079 14.[(D x 60) + C]
The last digit in the north coordinates is 3 and the last digit in the west coordinates is 7.
