I was doing some work in central Oahu a few years back, and stayed out at
the Turtle Bay hotel on the North Shore. One day we were out nosing around
the area and ran across the site of that old Beverage. Some of the old
timers who live out there still remember it. Also, there is a road named
Radio or something in that vein which is what first attracted our attention.

Hi All,

I have some info on a Beverage antenna that I believe you'll find
interesting.

During 1942-43 I was with the Radio Intelligence Division of the FCC in
Hawaii,
monitoring enemy transmissions. One assignment by the State Department was
to
determine whether the Japanese in Japan were getting the same information
from
their local broadcasts as the propaganda broadcast on HF, or different
information concerning the progress of the War.

On searching the AM broadcast band for Japanese stations we found JOAK,
Tokyo,
on 650 kHz, with an exceptionally strong nighttime signal. However, KNX,
Los
Angeles, also on 650, was equally strong, making copy of JOAK impossible.
Consequently, two of my colleagues, Prose Walker, W4BW, and Edwin
Rudisuhle,
K6SAC, installed a Beverage antenna on the northern shore of Oahu to
reduce the
interference from KNX. The Beverage was more than one-half mile long at a
height
of 10 feet, aimed directly at Tokyo, and terminated with a variable
resistor.
The signal from KNX was totally nulled out with the adjustment of the
terminating resistor.

The State Department was pleased with the results, because we were then
able to
record the JOAK broadcasts daily, with the records sent to Washington
daily by
US Army planes from Hickam Field, Honolulu.
