Radio Liberty Fans Wonder Whether One of the World's Great Shortwave
Stations Will Really Be Dismantled
by David L. Hollyer
A leading Spanish newspaper recently reported that the governments of
Spain and the United States had reached a political agreement for the
cancellation of the lease contract under which the U.S. government has
maintained and operated the facilities of Radio Liberty at Playa de
Pals.
The Spanish Senate approved a motion to dismantle the antennas and
structures that occupy the 1-1/2 kilometers fronting the Pals beach. The
City Council of the town of Pals declared that 90 percent of that
terrain would be declared a "green area."
The fate of the historic facility remains in doubt.
Russian service
For more than 40 years, the Radio Liberty short-wave transmitters at
Playa de Pals, on the Costa Brava in Spain, pumped out broadcasts of
news and information around the clock to listeners in the former Soviet
Union and people of that area who could understand Russian or one of the
associated languages. Their targets included most of Central Asia via
second hop.
The brainchild of the late Colonel S.Y. McGiffert, chief engineer of
Radio Liberty, the site at Playa de Pals, about 75 miles north of
Barcelona, was selected in the late 1950s after he and an engineering
team investigated many kilometers of beachfront locations in Spain. It
was chosen as the best possible spot for banging in a shortwave signal
into the Soviet Union.
The colonel demanded a site with ocean in front of it to provide maximum
reflection area for the transmitting for the transmitting antennas. He
got everything he wanted in the Playa de Pals location.
He also got an 82-acre chunk of land, arguably one of the best pieces of
beachside real estate in all of Spain. And thereby hangs a tale. The
colonel had powerful connections in Washington that helped him negotiate
for the site and eventually obtain a lease on it despite protests of
envious development interests that were already aware of the emergence
of the Costa Brava as a major tourist mecca.
McGiffert never did things halfway. He hired gilt-edge engineering firms
to design the antenna arrays, towers and support structures. Work to lay
out roads and build the office/transmitter building started on the site.
Installation of four Continental Electronics 250 kW transmitters was
begun by engineers from Continental Electronics, assisted by staff
technicians. An additional stand-alone 100 kW Telefunken transmitter was
installed.
Antenna Groups "A" and "C" were completed first and
situated between the antenna switchhouse and the sea. "A" and
"C" Group towers were constructed by Brown-Boveri Co. The
towers were freestanding, several hundred feet high. Strung between them
were the antenna arrays. Made up of cage-type radiating elements, they
were backed up by a reflector grid.
In Group A, the two antennas covered the 9, 11, 15 and 17 MHz bands,
while in Group C the two antennas covered the same ranges. The
configuration consisted of three bays in line, each bay with four
stacks. Remote switching permitted using the upper and lower antenna
elements or both to achieve vertical "slewing" to change from
a low take-off angle to a higher take-off angle.
Vertical "slew" angles were changed in accordance with the
ionospheric layer height at the time of transmission. Horizontal
"slewing" or steering of the beam from center to 11 degrees
either side of center was accomplished remotely by cutting in delay
lines.
The design was elegant and state-of-the-art.
Standing tall
When I arrived in Playa de Pals in the fall of 1961, Group B antennas
near the entrance were under construction by Spanish firm Miguel Mateu.
These were for operation on 6, 7, 11 and 15 MHz. Work on Group D
antennas, at the far end of the beach, had not yet started, because the
spot for their installation was swampy. It had to be
"dewatered," or pumped more or less dry, for a year before the
massive cement foundations for the guy anchor could be poured.
We employees kidded the resident civil engineer, the late
"Toby" Taylor, that he was trying to pump the Mediterranean
dry.
Eventually, the dewatering work was finished and the pouring of the
massive cement bases for the ground anchors was completed. The erection
of the steel support towers for the radiating elements and the reflector
grid was begun. It took months.
Back at the station, work advanced on the audio control room and internal
wiring. Part of the building was devoted to offices and the remainder to
the technical installation.
The facilities were great. They included a good restaurant, with meals
partially subsidized and affordable. As most employees didn't have
automobiles, busses brought them to the site from centralized pick-up
points in nearby Palamos and Palafrugell, where most of the Spanish
employees lived.
Eventually work was completed on the Group D support towers, built by
CIFA of Milan. And they were tall. The tallest of four guyed towers
stood over 540 feet, close to the height of the Washington Monument.
One pair of the guyed towers supported the antenna elements, while the
other pair suspended the reflector grid. The structure was designed
cleverly so that both the antenna and the reflector were held up by
cable, which ran on pulleys.
Whenever the breeze blew - and this was often, at the beach - the front
antenna array would tend to belly in. Tied to the ends of the support
cables was an elaborate system of counterweights in frames at the base
of the towers. The reflectors were equally counterbalanced. In a stiff
breeze, both the antenna elements and the reflector grid would belly in,
becoming concave. But thanks to the counterweighting, they would
maintain their critical separation space and hence keep an excellent
standing wave ratio, even during periods of heavy wind.
There were three antennas in this group. D1 operated on 7 MHz; D2 on 9
and 11 MHz; D3 worked on 15 and 17 MHz. D1 consisted of one bay having
four stacked horizontal cage dipoles backed by a screen reflector. D2
and D3 consisted of two bays, each having eight stacks of horizontal
cage dipoles backed by a screen reflector.
D2 and D3 could be slewed vertically to three positions. Through remote
electrical switching, the antenna elements could be combined to provide
three vertical take-off angles: a low of 4 degrees, a medium of 8
degrees and a high angle of 12 degrees.
Take-off angles were selected to accommodate any ionospheric height for a
specific Russian target. The antenna could be "slewed" or
steered laterally plus or minus 12 degrees off center by introducing a
delay line between the bays.
What a magnificent antenna. It represented the most sophisticated and
versatile antenna design available, which even today has not been
improved upon.
Phaseout
In preparing this story, I would be remiss if I didn't acknowledge the
assistance of my colleague Valenti Carbonell, a consulting engineer in
Palamos, Spain. Over the years, he filled many engineering positions at
the transmitter site. Whenever I've forgotten a detail or needed
information on the antennas, Valenti, with his encyclopedic knowledge of
the antennas, provided an assist.
Over the years there were technical changes at the site. A 250 kW General
Electric transmitter was installed. The 100 kW Telefunken was retired
and a Marconi 250 kW installed.
The voice-quality program line used to bring in program material from
Munich gave way to better program lines and eventually to a satellite
system, which delivered programs from the International Broadcast Bureau
in Washington.
I left Playa de Pals in 1964 to work at Radio Liberty headquarters in
Munich. Thirty-one years later, in the spring of 1995, I was summoned
out of retirement to take a job at Playa de Pals to replace the retiring
manager. It was to be a short-time assignment as managing director. The
facilities and assets of Radio Liberty were being turned over to the
IBB, a government umbrella agency, which controlled the Voice of
America, Radio Free Europe, Radio Liberty, Radio Free Asia and Radio
Marti.
My stay lengthened into six months, during which time a team from
Washington came in to cut the staff drastically, terminate bus
transportation and subsidized meals. It was a process to cut costs and
staff dramatically.
A new IBB manager arrived and took over management duties. The station
continued in service until May 25, 2001, when the government terminated
operation of Radio Liberty, abruptly stopped broadcasting and sent the
staff home.
IBB claimed that their former shortwave listeners were now well-served by
local FM and satellite broadcasts and that shortwave transmissions had
outlived their usefulness. The station was mothballed, with the specter
of dismantling in the offing.
As I write, some changes have taken place. The U.S. Congress has
apparently had second thoughts about the cancellation of the lease
contract and the dismantlement of the Playa de Pals transmitter site. It
has gone back to Radio Nacional, the Spanish government agency that
holds the lease, to request that the lease cancellation and the
dismantlement be rescinded and that permission be granted to reactivate
the transmitter site and use it for broadcasting to the Muslim
population, presumably in Central Asia.
Up to now, no decision has been taken to allow that to happen. Meanwhile,
powerful Catalan political forces strongly oppose any such cancellation.
Having had that beautiful beach property almost within their grasp, they
understandably are reluctant to have it slip through their collective
fingers. At least one informed source in Spain feels the station is off
the air forever. Radio Nacional apparently intends to transfer the real
estate to either the national or provincial government, and the Playa
operation has lost all of its operating permits, of which there are
three (national, provincial and city). The political problems to
re-obtain these licenses may be insurmountable.
In the meantime the facility's fate is in limbo. Those who admire the
site, myself included, would hate to see the destruction of such a
valuable facility. If the U.S. government is able to make its case and
put this site back into operation to continue its war of words, Pals may
yet light up its transmitters again and pump its broadcasts to a Muslim
population.
The outcome is unclear and bets go either way. As the Spanish might
express it, quien sabe? Who knows?
