which were anchored to 1’-diameter copperweld
ground rods and clamps. Sufficient space existed
under the main structure roof for a User-furnished trailer. A 12’ x 22’x 10 wooden building located adjacent to the station was built for use as
a “Bogue” generator shelter. Power requirements
consisted of two 25 KW, 120/208-volt, 3-phase
generators and the User-furnished Bogue set.
Four pair of timing signal wire were required.
A total of 15 cubic yards of concrete was

Station 1810 was utilized for mirror imaging and was located in Room B and part of
Room D within Station 1310. Room D was
divided by two wooden partitions 4 feet apart
from wall to wall and floor to ceiling, with doors
in the center. Room B was divided into three
separate rooms: one isolated screen room 9-6”
x 11’ with a 20,000 ohm resistant, a large instrument room, and a light channel room 2 feet
wide the full length of Room B.
