THE DAY THE SPOOKS STEPPED ON MA BELL
|
|
By: Donald E. Kimberlin
|
|
|
|
There's nothing in Bell advertising to dissuage the public
|
|
of its common notion that Bell runs the entire realm of
|
|
telecommunications worldwide. The extent of this misapprehension
|
|
shows in items like the widespread news report that bombing of
|
|
the telephone building in Baghdad was "the AT&T building" proves
|
|
our press knows no better than to continue to mislead the public.
|
|
AT&T isn't about to help, either, when it publicizes its
|
|
placement of earth stations in the Gulf War zone, never telling
|
|
the public it rented them from Alascom, a firm with no ownership
|
|
by AT&T.
|
|
But people in other nations know AT&T doesn't rule the roost
|
|
of telecommunications. Sometimes they just have to let yet
|
|
another stubborn Yank learn the hard way, one more lesson at a
|
|
time. Sometimes that stubborn Yank is one like me.
|
|
My lesson occurred in 1963, while employed by AT&T in one of
|
|
the three shortwave radio operations they ever built. It was in
|
|
Fort Lauderdale, Florida, the plant operation providing the
|
|
communications channels they public used to Central America and
|
|
the Caribbean.
|
|
Few today even give a thought to how they got telephone
|
|
connections to other countries in a time before there were
|
|
satellites and underseas telephone cables. To the outside world,
|
|
no one knew a crew of us was on the scene behind what they heard
|
|
was the "Miami Overseas Operator." That operator just pushed
|
|
plug into a jack on a switchboard and spoke to an operator in the
|
|
other country. That jack was just wired to us at Fort Lauderdale,
|
|
where we launched the voices off to bounce from the ionosphere
|
|
via high-powered transmitters and rhombic antennas to other
|
|
nations. In the other nation, the operation and people all
|
|
belonged to the telephone company of that nation ... independent
|
|
and soveriegn in their domain as Bell is within its domain.
|
|
The independent other nation in this story was Costa Rica,
|
|
and its international operation was Compania Radiografica
|
|
Costarricense, a nationalized descendant of the "banana republic"
|
|
era operations started there by Tropical Fruit Company of Boston
|
|
before World War I. Radiografica was one of the best, most
|
|
stable points we worked, and even if one had the notion of
|
|
talking via "shortwave radio," their operations with us were so
|
|
good that most of the time, you'd never know it.
|
|
For many years, we had only two channels to San Jose from
|
|
the U.S., and Radiografica also operated links to other Latin
|
|
American nations such as Mexico. These were, of course, multiple-
|
|
channel independent sideband radios, so two channels meant we
|
|
were interested only in having clear radio spectrum "space" only
|
|
three kiloHertz above and below the carrier frequency. We would
|
|
have to change carrier frequency two or three times a day, to
|
|
higher frequencies in the daytime and lower frequencies at night.
|
|
One of the best frequencies we enjoyed with San Jose was 15580
|
|
kHz, a spot now used by international shortwave broadcasters. It
|
|
was assigned the call letters TIW 55 to Radiografica by the Costa
|
|
Rican government.
|
|
In that summer of 1963, Radiografica opened up two
|
|
additional channels with us. This meant that the added channels
|
|
would occupy radio spectrum "space" out to 6 kHz either side of
|
|
15580 when TIW 55 was on the air. by and large, this was clear
|
|
space and we had two added channels all day free of any noise or
|
|
interference.
|
|
Except ... the day we started using the additional space, a
|
|
Morse code transmission popped up low into the new Channel Four.
|
|
It just called somewhere else over and over, sending, "JW de IQ,"
|
|
or something of the sort. It was about 1 kHz inside our channel,
|
|
producing very clear Morse code in the telephone circuit between
|
|
San Jose toward Miami. Every afternoon, for a couple of hours,
|
|
it continued on and on. It never sent anything else; it never
|
|
seemed to make contact with whoever was on its other end.
|
|
I often was assigned to the group of channels that included
|
|
Costa Rica, and we enjoyed excellent relations with our
|
|
coordinates there. They spoke perfect English for our benefit,
|
|
and it seemed there were things they knew that we didn't know, at
|
|
least in this case. We of course, could not use the interfered-
|
|
with channel for a public telephone circuit, so we would cut it
|
|
off, waiting for the interference to clear, leaving the other
|
|
three for the Miami operators to use. But, since the traffic was
|
|
so heavy, Miami wanted the circuit. Our alternative, to shut
|
|
down all four momentarily and use some other frequency that might
|
|
produce four channels, but noisier, was not attractive.
|
|
Whenever there was interference, we performed an
|
|
"observation" of who it was. We had all the good tools - elegant
|
|
receivers, radio direction finder, spectrum analyzers and
|
|
demodulators for every kind of telegraph and facsimile. There
|
|
wasn't much we couldn't identify and pin down to its source.
|
|
And, there's a whole system of rationalization for settling
|
|
territorial disputes on radio between countries. It's called the
|
|
International Frequency Registration Board, a function of the
|
|
Comite Consultatif Internationale des Radio (obviously not a French
|
|
name for our francophone readers - it's a modern Swiss
|
|
bastardization of French), an arm of the International
|
|
Telecommunications Union. Drawing its authority from treaties
|
|
all United Nations members sign, the IFRB is the repository of
|
|
registrations each nation sends to Geneva, with seniority claims
|
|
of use, so interference complaints between nations can be
|
|
arbitrated when they occur. Our "tool" was a copy of the multi-
|
|
volume International Frequency Register, IFRB's computer printout
|
|
of every radio transmitter licensed by every nation in the world
|
|
... except for military, intelligence and clandestine operations.
|
|
The source of my problem, even though it could be clearly
|
|
heard, was of course not listed in the IFRB books. I made out a
|
|
report each day, and it didn't go away. I asked our San Jose
|
|
colleagues, and they immediately showed signs of knowing it was
|
|
there, but offered no information about who it was. I asked if
|
|
they could contact it, as my direction finder had showed it was
|
|
coming from somewhere near their direction, and all San Jose
|
|
would say was they "would try." Nothing happened, and we
|
|
continued to lose a couple of hours on that channel each day. I
|
|
suggested to the San Jose staff that if they knew who it was, if
|
|
they would just slide down the band about a kilohertz, they would
|
|
fall in between our channels and we could co-exist with them.
|
|
San Jose said they "would try." Nothing changed, and we kept
|
|
losing channel time.
|
|
Finally, my Yankee sense of fairness and my short temper
|
|
combined to make decide to take some definitive action. That was
|
|
to make a complaint via official channels, in this case the FCC
|
|
Field Monitoring station (then) at Fort Lauderdale. Because AT&T
|
|
is not in charge of the world, any officially-registered
|
|
complaint through IFRB channels has to be observed by them, and
|
|
forwarded by them. We talked to the FCC monitoring station with
|
|
fair regularity, so it only took a local phone call.
|
|
Again, somebody else knew more about the interloper than did
|
|
I or Ma Bell. As soon as I mentioned the frequency and the call
|
|
signs, the FCC duty officer replied, "Oh them? Are you really
|
|
certain you want to file a complaint?" I asked what was wrong
|
|
with doing so, and he said, "Oh....nothing, I guess. But maybe
|
|
you don't really want to make a complaint." He certainly knew
|
|
who it was, but he wasn't going to tell me, nor would he advise me
|
|
there was any adverse result to doing so. I insisted, so pressed
|
|
on to file a complaint.
|
|
Nothing happened for a couple of days. We used TIW 55 daily
|
|
for many hours, except for the couple of hours interference to
|
|
that one channel each afternoon. Then, on the third day, at
|
|
about 9 or 10 AM, I asked San Jose to change frequency to TIW 55,
|
|
I found out what had happened.
|
|
Just 48 hours after my going on record with the FCC, my
|
|
colleague in San Jose said, "I'm sorry to tell you the Costa
|
|
Rican government has cancelled our license to operate on TIW 55.
|
|
You'll have to choose another channel, Old Man."
|
|
The spooks indeed stepped on Ma Bell that day.
