3. A laboratory in the United States Army Electronics Command at
Fort Huachuca processes a DD Form 1494 for the development of a new
item of communications-electronics equipment.
What element of the
Office of Assistant Chief of Staff for Communications-Electronics
should process the form and make the frequency allocation?
4. Frequency assignments fall into three broad categories. Which of
the following does not fall into one of the three categories?
a.
Assignments
used
for
command
and
administration
(non-
tactical).
b.
Assignments used for tactical and training purpose.
c.
Experimental
assignments
in
support
of
research
and
development of communications-electronics equipment.
d.
Assignments used
for
tactical
and
training
purposes
in
foreign areas.
5. The Communications-Electronics Resources Management Directorate
is responsible for the processing of equipment allocation actions.
a.
True.
b.
False.

31. General (Compatibility Program).
Congestion of the radio frequency spectrum has been evident
since shortly after World War II. Since then it has been understood
that many of the concepts for communications-electronics systems
under development would require additional spectrum resources as well
as
better
management
of
the
spectrum.
Experience
with
communications-electronics equipment at the densities planned for
future Army operations is limited; however, even at current
densities, interference between equipment has long since become a
problem.
Today, the Army in the field may contain over 100,000
communications-electronics devices.
In contrast, the number of
communications-electronics devices in a field Army in World War II
was
approximately
25,000;
in
Korea,
approximately
45,000.
Estimates in 1975 place the number at approximately 160,000; thus,
concern
about
spectrum
saturation
led
to
studies
of
based
upon
expected
densities.
These
studies
confirmed the existence of serious problems and resulted in
