The Work of FCC's Foreign Broadcast Intelligence Service
By OLIVER READ.* W9ETI
The Foreign Broadcast Intelligence Service of the Federal Communications Commission is responsible for a great
portion of the news that finds its way to our daily newspapers and is heard over our vast radio networks. You have
often heard the following: "As recorded by United States monitors," or, "As heard by United States Government
This maze of wire is but a small part of the elaborate system required to receive faint radio signals emanating
from all parts of the world. The wires connect to twenty-nine communications-type receivers within the listening
station located near Silver Hill, Md.
All programs received at Silver Hill are "piped" through this monitoring console. The operator on duty adjusts
the volume of each station to a predetermined level suitable for recording purposes before it is sent on its way
to the interpreter who is situated many miles from the receiving station.
David Cooper, FBIS supervisor, records a broadcast on a Memovox machine at the recording station. Over an hour's
intelligence may be recorded on each side of a flexible disc. Continuous recording is possible by using
duplicate machines. The console at the left is used for the recording of vital material where the utmost in
quality is required.
The monitoring officer in the foreground adjusts the receiver of a station to be monitored a few minutes later.
The officer in the background scans the ether for new or unknown stations.
Instantaneous frequency checks may be made at any time by connecting this special switch.
Who are these monitors and what do they do? As a matter of fact, they operate one of the world's most elaborate
systems of radio receivers. Their purpose is to listen to, record, translate, summarize and report the broadcasts
originating in foreign countries. The FBIS is the sole governmental agency doing this job in the United States.
They do not transmit propaganda; that is done by the Office of War Information.
It is interesting to note
that the very development of the FBIS was born from the realization that short-wave transmission was one of the

potent weapons of war. Our enemies have bombarded us
with all sorts of propaganda throughout this war. From it the FBIS is able to gather vital information which is
then used for counter propaganda.
In the early stages of the war, the French followed a not very successful
policy of attempting to jam German broadcasts reaching the vicinity of Paris. However, the French Foreign Office
deemed it so essential to keep informed of the contents of those German outpourings that it established a
listening post in Switzerland to intercept the very broadcasts which its own jamming prevented it from hearing
Today, every major nation in this global war and most of the neutral countries operate a
monitoring service as part of their essential government functions.
The maze of equipment required to handle the vast number of words recorded and translated each day is
tremendous. In fact, over 10,000 items (an average of 2,500,000 words) are received daily at FBIS listening posts
at Silver Hill, Md.; Hayward, Calif., and Portland, Ore. Manned largely by amateur personnel, these stations are
tuned in twenty-four hours a day to programs being transmitted from all the countries of the world.
Silver Hill Installation
We visited the elaborate installation at Silver Hill, Md., recently in order to witness firsthand the
important functions of the FBIS.
There we found the chief monitoring officer to be Frank X. Green, who has
long been associated in the radio, public address and recording business. He entered the service of the Commission
at the outbreak of the war. There are four monitoring officers: Conan W. Barger, formerly radio broadcast engineer
of KFXJ, KFEL, KOA, KMA and KIUL; Francis N. King, who was radio broadcast engineer at WKBW, WHBU and WJTN, and
formerly a short-wave radio operator on the Great Lakes; S. Vernon Ray, former radio operator in the merchant
marine, and Bernard P. Sloan, W2KT, former chief radioman in the Navy and the Coast Guard and an operator in the
Assistant monitoring officers include: William A. Sodaro, former chief engineer of a West
Virginia network and radio operator from the Gulf of Mexico; Raymond B. O'Neill, former telegraph operator with
the New York Police Department; Hyman Wallin, formerly a merchant marine radio operator; James G. Wedewer, an
official of several shortwave listening clubs and an outstanding authority on short-wave broadcast stations of
the world; George E. Hathaway, former radio operator in the merchant marine, the Army, and for Western Union, and
Russell G. Eversole, W3AXY, former radio operator in the merchant marine.
This fellow James Wedewer
mentioned above can give you the location of any listed short-wave station or broadcast station throughout the
world. We had quite a talk with this lad and picked call letters out of "blue sky" to test his ability to
recognize the station. His quick identification was amazing. The receiving station at Silver Hill is concerned
only with broadcasts originating from European and African short-wave stations. The other FBIS receiving stations
are very similar to that situated at Silver Hill, Md. The one at Portland, Ore., takes care of Japanese-language
broadcasts and the one at Hayward, Calif., records signals from the Far East and from the U.S.S.R.
Functions of the FBIS
There are nine successive steps in the operations of the
FBIS: (1) scheduling; (2) intercepting, (3) and (4) monitoring and recording (which go on simultaneously), (5)
translating, (6) wire service which includes editing and teletyping, (7) reports which include editing and
mimeographing, (8) analyses including periodic and special reports, and (9) individual services of many kinds.
First comes the scheduling of all programs which are to be intercepted at each listening post during each
listening period. An accurate index which includes frequencies, hours, languages, and program types is prepared.
This comprehensive index lists over 6000 programs and is kept currently accurate.
Step number two is
performed by the engineers, each of whom is in charge of a large number of Hallicrafters SX-28 communications-type
receivers which are in continuous service. The performance and calibration of each receiver is known at all times.
A gadget has been installed by the FBIS personnel so that a 100-kc. or a 1000-kc. signal may be injected to any
receiver for a frequency check by connecting a special switch. The source of this signal is a crystal-controlled
secondary frequency standard.

used to cut programs in and out.
Having received his schedule, the operator tunes in in advance the requisite number of receivers to the
stations, making sure that. the signals are being received at best audibility. At precisely the right moment, he
throws a switch, or an automatic control developed by the FBIS, cutting in the proper programs for recording and
monitoring. He then retunes unused receivers to be held in readiness for following scheduled programs.
Other engineers patrol the ether continuously in search of new, changed, and discontinued programs so that an
accurate "log" is always available. All programs are listed on a daily chart which gives a report on the
audibility, signal strength, etc., of each program.
The antenna system consists of five highly directional
Rhombic antennas orientated to cover a maximum of 20 degrees each. All of the Rhombics terminate to selector
switches so that any or all of the twenty-nine receivers may be instantaneously connected into the feeder system.
All inputs connect in parallel and series isolating resistors to each receiver input permit an even distribution
of received signals.
Like the RID, the personnel of the FBIS have installed their equipment in such manner
that greatest flexibility is realized. The receivers are installed in bays as shown in the photographs. They are
easily accessible from the rear to facilitate servicing.
There is a small selector panel on each receiver
bay which includes a voltmeter to check the output of the receiver, a selector switch for the speaker and another
to select the proper Rhombic. Each receiver has its own calibration book placed in a clip adjacent to the set. The
hand-calibrated information is prepared for each set in the installation. Operators can then determine by quick
reference the exact settings for a given frequency. Periodic checks are made, especially when sudden changes in
weather are encountered, to see that the calibration is accurate.
Each program received at the FBIS receiving station is recorded on a special log which shows the exact time of
reception and other pertinent information. The operator selects various programs by rotating the switch.
Mrs. Kay Kimmers, FBIS expert in Italian, French, Spanish and German languages, transcribes a program from
Europe. The same program is being recorded simultaneously on wax cylinders for reference purposes and for
Victor Volmar, FBIS monitor, specializes in the German and Spanish languages. Wax cylinders are kept for a
period of forty-eight hours and contain the original intelligence that has been received via the elaborate
receiver installation at Silver Hill, Md.
Incoming and, outgoing traffic passes through the teletype machines which supply information to many government
agencies both military and non-military. These include the War. Navy and State Departments, OWI, Office of
Censorship. and a number of branches in Allied governments.

Chris Kimbrough, and Mrs. Helen Goss.
A control console which includes patch circuits and db. meters is an important part of the installation. The
output from each receiver terminates at the jacks on the control console. From there signals are routed by wire to
the recording and monitoring office which is located many miles from the receiving station. The operator on duty
at the console "rides gain" on each channel in order that the signals arrive at the downtown office at proper
audio level for recording purposes. This allows the translators to concentrate on the intelligence without being
disturbed by having to adjust individual volume controls to suit their particular needs. Recording
Certain types of programs are recorded on paper-based discs on Memovox recorders or, when high fidelity is
required, on Presto acetate recorders. The latter equipment is located at the receiving station.
known as monitors sit before typewriters wearing headphones. This highly trained personnel consists of experts
familiar with many languages. Each monitor specializes in one or more. He is thoroughly familiar with the
phraseology and other characteristics of the language he is monitoring. As he listens he translates the material
and makes a typewritten summary in the English language of the broadcast. At the same time, dual wax-cylinder
machines record the entire program so that the monitor has a means of checking his copy and so that information
can be held verbatim for a period of forty-eight hours in case some governmental agency needs the complete program
for further observation and study. After the program's conclusion, the monitor goes on to the next one shown on
his schedule. Generally, he types only highlights of the program, but if the item contains information of real
importance in the judgment of the supervising editor-monitor, the monitor turns from listening in to a succeeding
music period and translates the full text.
The next step in the operation is interposed between monitoring
and editing for a portion of recorded broadcasts. It is known as the translation of texts. One of those in
constant demand is the weekly Goebbels Das Reich article. This is sent with the summary to the translation room as
soon as recorded to be rendered into English text. At present there are seventy-five expert translators in the
FBIS having ability to undertake thirty-four languages and thirty additional dialects.
Distribution of Material
The sixth, seventh and eighth steps in FBIS operations
deal with the distribution of material to various government agencies which use it. From the various listening
posts come summaries, texts and daily round-ups that flow into Washington headquarters minute by minute, day and
night. They come by typed transcript, by teletype, by cable, and by air mail and are then distributed to the
The information goes out over six wires. The " A" wire terminates at the State Department, War Department,
Navy Department, OWI, Office of Censorship, British Information Service, Canadian Wartime Information Board, the
Philippine Mission and Chinese Embassy. The "B" wire goes to OWI in New York and Washington. The "C" wire, with
Latin American material, goes to the office of the Coordinator of InterAmerican Affairs. The "D" wire is a cable
to the British Ministry of Information in England and carries Japanese material monitored on the Pacific Coast.
The "PW" wire goes to the War Department, Office of the Provost Marshall General, and contains the full text of
all enemybroadcast prisoners-of-war messages. The remaining "X" wire connects to OWI in San Francisco and carries
items relative to the Far East broadcasts from Europe.
The seventh step in FBIS operations is the
preparation and issuance of two mimeographed daily reports.
The eighth step is the analysis of the volume
of the recorded broadcast output, the preparation of periodic reviews of broadcasts from and to particular areas
and the answer to the steady volume of queries regarding a particular subject, trend, or transmitter.
The ninth and final step deals with individual special services.
Principal speeches by German and Japanese leaders are recorded on the permanent high fidelity discs previously
mentioned and are furnished to the OWI and the British Overseas Broadcast Agency for the Library of Direct
Quotation. These recordings have been used to good advantage in our own counter-propaganda. For example, six
months after Tojo had broadcast a boast about the impregnability of the Marshall Islands, there came bouncing back
to Japan his actual voice with its six-month-old boast accompanied by the damning facts of the actual Marshall
Island invasion. The Foreign Broadcast Intelligence Service is one of the Government's most important nonmilitary
branches. We hams may take pride in the fact that the FBIS has selected much of its personnel from our ranks to
operate this vital wartime agency.

Note: The Wikipedia entry for the FBIS was apparently written by some puke with an
agenda of diminishing
the important role it played in national security during WWII and focusing
instead on some activities
proclaimed to be fomenting unease in the American populace.
