This from Jielun using her hand-held GPS:
Larry and Steve,
Here are my GPS readings. Somehow, I didn't get A8 and A9 right, so you can ignore their numbers. I also plotted all the locations. They look pretty good. The red M is the main tower, the green C is the C tower, and the blue line is the fiber-optic line.
