The JT receiver loaded and secured in the back of our 98 Chevy 4X4 pickup.
One more inspection before the trip to Mt. Graham
Steve filling the pickup up again in Safford because it took 3/4 of a tank of gas just getting there. Too much wind resistance. The maximum speed obtainable during this trip was 55 MPH.
Engineers preparing to host the receiver from the chamber up to the 5th floor hatch.
Bob Freund and Bob Moulton prepare tag line before the lift.
The JT receiver, safely in the right receiver room, gets it's final assembly before attachment to the flange.
The following 6 images are plots of the G forces experienced by the JT receiver during transportation to Mt. Graham. All measurements where made using a HiGeeLoGee Model 30 G-Force recorder. The first three plots are on the Willcox to Base Camp leg. This first plot is the front to back G's.
This second plot is the side to side forces on the Willcox to Base Camp leg.
This third plot shows the vertical forces on the Willcox to Base Camp leg.
These next three plots are for the Base Camp to Mt. Graham leg of the trip. This first plot shows the front to back forces.
This second plot shows the side to side forces experienced on the Base Camp to Mt. Graham leg. Notice the nearly -1.0 G force 2/3 of the way. This was due to hitting a rut in the very muddy road and causing a large side to side motion.
This third plot shows the vertical forces on the Base Camp to Mt. Graham leg.
