no good.
They dart about constantly,
day and night, all over the
world, doing mischief.
Sometimes they are no worse
than childish pranksters. Some
times they are wanton destroy
ers; they conceivably could be
come agents of doom.
The United States and other
nations, including Russia, are
spending huge sums and much
effort in attempts to exorcise or
thwart them.
Whether merely mischiev
ous or malevolent, the imps are
electro-magnetic signals, man
made and natural. Their men
ace stems from what is called
radio frequency interference, or
RFI.

tions and radar observations. It
has been at least suspected of
responsibility for some air dis
asters. In a time of war it just might
pose a threat to missile and ra
dar defenses.
Progress Is Made
Scientists are making consid
erable progress in their efforts
to cope with RFI, but their bat
tle appears tu be never-ending.
Any electrical or electronic de
vice, from a motorized mouse
trap to a monster television
transmitter can generate RFI.
So can a lightning bolt or a
magnetic storm triggered by so
lar flares. Most RFI is acciden
tal or unintentional. Sometimes,
as when the Voice of America
is jammed by Soviet transmit
ters, it is neither.
In war. an enemy presumab
ly would try every trick known
to radio technology to mess up
our communications, warning
systems, and missile launching
and guidance equipment.
Often it is a case of radio
frequency conflict among com
ponents of the same system. In
May, 1059, for example, a stray
signal from an Atlas guidance
system fired the missile's "de
strucl" charge. Loss: $2.5 mil
lion. Such incidents can be held to
a minimum, at least, by tricky
circuitry, artful shielding, pre
cise tuning, and intricate cod
ing of so - called radio com
mand messages. But there is
always the unexpected to con
tend wll'i.
Cannot Be Certain
There is no way of being cer
tain all parts of an exceeding
ly complex electronic system
will be olcclromagiicticully
"compatible" until all of them
are put in operation simultane
ously. And not unless war comes,
can such a test be made of the
compatibility of elec Ironies
aboard intercontinental mis
siles in their silos, radars in
warning systems and anli-mis-sile
missiles, and radio devices
in military space and land
based communications.
Realization of these uncer
tainties led Ihe Defense Depart
ment in 1061 to set up at An
napolis, Mil., the electromagnet
ic compatibility analysis center
whose main job it is to predict
potentially disastrous RFI con
ditions. In a recent statement
the center said:
"Since the (military) services
rely on the use of a tremen
dous number of electronic do
vices, used for communications,
command and control of weap
ons systems and a variety of
other purposes, unintentional In
terference represents a poten
tial threat to military opera
tions. "Peacetime problems, such as
air traffic control, are also of
concern."

H mill '-rs rlnll'ir A nrortiilic '
center is secret. But it is no Re-
crct that in this increasingly
electronic world the RFI prob
lem is becoming more serious
and even dangerous.
Too Much Radio
As one authority said: "There
is simply too much radio in the
world. Every time you turn
around someone invents a new
device using radio energy. It's
like an over-crowded highway.
If too many crazy drivers get
on Ihe road, you have trouble."
This man said no end to elec
tronic invention is discernible.
He said "there are electronic
mousetraps, electronic cameras,
electronic parage doors, elec
tronic everything."
But the radio spectrum is not
unlimited and there are not
enough "clear channels" to go
around. Hence, RFI.
If it were just a case of loo
many gadgets operating on the
same frequencies at the same
power level in the same part
of the world the situation might
be easirer to control. At Cape
Kennedy, (Canaveral) (or ex
ample, authorities shut down ra
dio transmitter and other elec
trical equipment in the area be
fore a launching.
Some Not Anticipated
Some things can't, at present,
be anticipated, although the An
napolis center, with the help of
big computers, is trving to de
velop an interference predic
tion system.
When developed, hnw ever,
such a system might not be able
In forecast what happened at
Ihe Point Mugu, Calif., launch
complex some time ago.
Drivers of radiocabs at t h e
base kept getting instructions
they couldn't obey. They might,
for example, be ordered to go
to a non-existing building.
After three months of this, it
was discovered that a similar
service at an Alaska base was
operating it cabs on the same
frequency.
Because of freakish and un
predictable radio reflection con
ditions, the California cabs were
getting clear instructions from
Alaska but weren't hearing their
own dispatcher. Point Mugu had
to change its frequency.
Merely Mischievous
Some of Ihe RFI imps, as
noted, are merely mischievous.
They explode photo flash bulbs
in stores from time to time
when a radar-equipped plane
flies over. They create snow on
the television screen for not too
different reasons. They make
radio-controlled garage doors
roll up and down when the re
frigerator turns on.
Often Asked Question
An often asked question is
whether a hostile submarine
lurking of Cane Kennedy (Can
averal) or Ihe West Coast Mis
sile range and destroy a just-
launclied rocket.
Many a rocket has been pur
posely destroyed in flight by a
radio command to its dcstructl
charge when it went off course.
These built-in charges are de
signed to blow up an errant
rocket on command from the
ground before it can do nnv
damage to any of the commu
nities upon which it might oth
erwise fall.
Experts say a Soviet sub
could trigger a U.S. rocket's de-
struct mechanism only if it had
transmitting devices operating
in perciscly the same way as
the ones used by the American
ground controllers.
"This," said one authority,
"seems highly unlikely."

It is hard for a layman, grop
ing among supurioiis signals and
possibly apocryphal tales, to
tell what is false and what is
fact in Ihe KF1 jungle.
Take Ihe case of the ghostly
icievision rrograms. the ex
tremely short wave television
signals are supposed not to ling
er in the earth's ionosphere, the
region of charged gas particles
which mirrors longer waves and
makes ordinary long distance
radio communication possible.
But strange things happen in
the inosphere, and sometimes I
microwaves, which should ram
ble on through to outer space,
get bouneri back to earth, pos
sibly by Ihe ionized trails of
burning meteors.

TO BE REMOVED Carved from rock 3,000

Ramses II wait to be cut up, removed and
reassembled on a new location. Under an

ABU SIMBEL. Eevnt (UPI)
The fresh holes in the cliffs
where archaeologists and engi
neers havo just made lest bor
ings are like a sign of doom to
the tourists.
Black scarabs scull Ic in the
sand and wild dogs howl. But
determined tourists, guidebooks
in nana, arc working irantically
against time to see the famed
temples at Abu Simbel before
they arc chopped up and moved
for eternity from the cliffs out
of which they were carved 3,000
years ago.
Under an appeal from the
United Nations Educational,
Scientific and Cultural Organi
zation (UNESCO), 47 countries
of the world, rich and poor,
have agreed to scrape together
36 million dollars to save the
two temples before they are
drowned by rising Nile waters
irom the new Aswan Dam.
Contracts have been signed
with engineering firms to carry
out a bwedish plan to chop the
temples into five-ton hunks and
reassemble them in a new
building on top of the cliff
where tourists can see them for
future centuries.
Can Pull Out
Egypt agreed to this plan ear
lier on Nov. 15, but has an es
cape clause. The United Stales
is one of the 47 countries which
have promised moncv for
the project. The American
share was agreed to be $12 mil
lion but Congress has not yet i
appropriated tne money.-
If Congress docs not act by
March 15 next, according to
UNESCO Director-General Rene
Malicit, Egypt can cancel t h e
project and pay an indemnity
to the seven firms Swedish,
German, Italian and Egyptian
which have contracted to cut
up the temples and move them
to safe ground.
Mahcu said engineers are op
timistic it can be done, al
though some archaeologists arc
"worried" about the delicate
operation of culling Into the
crumbling temples with their
sculptures and carvings.
Among Great Wonders
The temples are one of the
great wonders of the ancient
world. They were built during
the reign of Ramses II, around
1232 B. C.
They stand alone on a sandy
bank of the Nile, more than six
miles from the nearest village.
Recently a group of American
tourists, including myself, trav
eled four days by boat, slept
two nights on the beach here
with the wild dogs and scarabs
and lived on green watermelon
in order to sec the ruins.
The trip began at Cairo on
a new Hungarian-made sleeper
train with wardrobe closets and
air conditioning that hurtles up
the river to Aswan. From there,
we took a Sudanese steamship
that runs from Ouadi Haifa,
Sudan, to Aswan and back.
Our cabinmatcs were Sudan
ese, Including women who wore
blue lipstick and gold jewelry
and painted the soles of their
feel and palms of their hands
black.
Satellite Over Horizon
As the boat steamed along
at night, a Soviet or American
satellite moved above the hori
zon over scenes unchanged
from those In the Abu Simbel
temples. Buffalo turned water
wheels. The landscape was in
shades of brown, from mud
adobe huts to camels, with
splotches of white that were
ibis birds and men in their
night shirt-like robes and tur
bans. Archaeologists from various
countries were digging along
the Nile banks for what treas
ures they can find before the
region is flooded by the Dam,
beginning next year.
Buys Pints of Water
The second night we discover
ed the boat stops here only .10
minutes in pitch darkness. The
agreed to scrape together $36 million to 3ave
Ihe two famed Abu Simbel temples before
they are drowned by rising Nile waters from
the new Aswan Dam. (UPI)
r-Old Statues To Be
From Waters of Dam
only way tu see the temples
is to get off and wait for it to
return from Sudan.
Six of us Americans bought
a pint of water each from the
steward, grabbed our luggage
and scrambled down the gang
plank. We slept, along with the
scarabs and sniffing wild dogs,
at the loot ol 165 icet high
statues of Ramses II in front
of the larger temple just a few
yards from the water's edge.
the lime to see Abu Simbel
is at dawn because it was built
so that (lie first rays of sun
strike the altar inside this tem
ple. As the sun rose, the colos
sal statues of Ramses changed
from gray to rose, then gold
and finally a sandy color In
the scorching sun.
The larger temple, dedicated
to Ramses and the god Re, has
three main rooms, its walls and
columns covered with engrav
ings of Ramses' war victories.
Nearby a smaller temple was
hacked out of the cliff in honor
of Ramses' wife, Ncfcrtarl, and
dedicated to the goddess Ha-thor.
