David Jessup June 1946 Behind the barracks, shown in the background, is the bombproof transmitter building containing the Very Low Frequency Alexanderson Alternator: The sole reason for the existance of Haiku NRS.
THE "BOMBPROOF" TRANSMITTER BUILDINGAt the left end of the building, just above the bushes, you can see the top edge of the hole where the antenna entered the building. Notice the huge insulators and corona caps needed to handle the immense power generated by the Alternator. The water tower cooled the Alternator and the diesel generator. The diesel exhaust stack is seen to the left of the stairway.
LOOKING DOWN FROM TRANSMITTER BUILDINGSailors shown left to right: John Rafaelli, Len Hardy & George Lee.IF you look closely you can see many black poles spread across the back of this photo. They support the ground system wires. This is a small part of the total system.
This Very Low Frequency Alternator transmitted 200,000 watts of radio signal at a frequency of 16.8 Khz. The 600 horsepower drive motor is on the left. The two coils above the Alternator are magnetic amplifiers, and are part of the antenna system. The alternator stands over six feet tall. Photo courtesy of Dr. Ronald Hillstrom
Looking East from the transmitter building at the motor pool and barracks.
THE SOUTH HOIST.When I first saw this chicken-wire covered cage I agreed to ride in it only after I understood the alternative meant climbing almost 4,000 rungs of a wooden ladder spiked to the south cliff.
David Jessup Summer 1946.I soon learned to enjoy riding this flimsy cage. Sudden wind gusts along the Haiku cliff caused it to sway in a very unsteady manner. When wind blew the return cable over the top of the main cable, the engineer at the lower hoist house would stop the cage and jerk it back and forth until the return drive cable was free. Clear days allowed a fantastic view.
