Libya, Part 1 – BFBS & AFRTS

 


Special thanks to Ray Robinson and Jeff  White for sharing a recent edition of Wavescan on AWR

Jeff: 13 years ago in 2011, one country that was very much in the news amid political turmoil and vicious fighting was the Arab Islamic State of Libya.  80 years ago, the same area featured prominently in the see-saw battles fought by the European powers during their North Africa campaigns.  This week, Ray Robinson begins a three-part series on the history of radio broadcasting in Libya, starting with the earliest wireless stations, and some radio broadcast stations that were operated by British and American personnel from shortly after the Second World War, up until 1970.  Here’s Ray.

Ray:  Thanks, Jeff.  The country of Libya is located in North Africa, approximately in the middle of the Mediterranean coastline.  Libya is about 1,000 miles north/south and also 1,000 miles east/west, although with an irregular shape.

Almost the entire country is covered by the Sahara Desert, with a 50 mile strip of arable land along the coast, and a few oases inland.  The hottest temperature ever recorded on Earth occurred in Libya on September 13, 1922, when the temperature was measured at 136 degrees Fahrenheit, 58 Celsius.

The current population of Libya is around 7.2 million and the capital city is Tripoli, although the largest city is Benghazi.  Oil was discovered in quantity in 1959, and these days the sale of oil forms 80% of the national economy.

This area of North Africa was inhabited by Berber tribespeople in earliest ancient times, and Phoenicians from the Palestine coast settled in the area around 700 BC. One hundred years later, the Greeks colonized the area, followed by the Romans, who in turn were followed by the Vandals from central Europe, and then the Arabs came in around the 600’s AD.  In 1912, Italy took over Libya, and after World War 2, Libya formally gained independence in 1951.

For those who have an interest in Biblical backgrounds, the original Berber tribespeople are descended from Noah’s son Ham; and Libya is mentioned by name in the Bible more than a dozen times.  The early Christian church remembered that a man by the name of Simon, from Cyrene in north eastern Libya, was arrested by Roman soldiers and was forced to carry the cross along the via Dolorosa in Jerusalem on behalf of the Messiah.

Wireless communication came quite early to Libya, and the first stations were installed immediately after the end of World War 1.  These early wireless stations were located in Tripoli as ICK; in Benghazi as ICJ; and Tobruk as ICU; together with four other regional locations.

However, radio broadcasting came quite late to Libya, and interestingly, the first medium wave stations weren’t installed until after the Second World War, and were operated by British & American forces personnel, not by the national government or commercial interests.  According to all available references, there was a total of six different BFBS stations on the air in Libya giving coverage to four different localities on AM, FM & SW; and just one AFRTS station on AM medium wave.

We look first at the British stations. According to Doreen Taylor in her book, “A Microphone & A Frequency”, the first two British stations were erected somewhat simultaneously during the year 1946, in Benghazi & Tripoli.  Both stations were quite small to begin with, using whatever electronic equipment was available.

The original station in Benghazi was located on what had been the Italian airfield, and quite soon, in 1947, an attempt was made to broadcast on shortwave.  The transmitter was an American-made RCA unit rated at 7½ kW, and the chosen channel was announced as 11820 kHz, though monitoring observations in Australia stated that the channel was more like 11850 kHz.  Unfortunately, these BFBS shortwave broadcasts caused interference to a regular BBC transmission, so the first attempt at shortwave broadcasting was aborted.

However, shortwave broadcasting was again attempted on two subsequent occasions; in 1949 on 4780 kHz, and in 1956 with 7½ kW on 4930 and 7220 kHz.

Two years after the station was inaugurated, Arabic programming was introduced for the benefit of local citizens.  Four years after that, the station was flooded following heavy rains in the hills nearby.  However, due to quick action on the part of the station personnel, very little damage was done to the station equipment.

The Benghazi station was closed in February 1958, but upon the insistence of King Idris, a smaller station was reopened in 1960 with 1 kW on 833 kHz, installed in an empty ward in what had been the base hospital in Wavell Barracks.  Later in the 60’s, a 4 kW FM transmitter was added on 97.8 MHz.  But, when most of the British forces left the area, the station was taken over temporarily by Signals personnel, and soon afterwards it was closed.  The last listing for the station in the WRTH is in 1968.

The BFBS station in Tripoli likewise had a double life.  It was located initially in the British army barracks at Mareth, and ten years later the station was transferred to Miani Barracks four miles away.  Likewise, shortwave coverage was tried from this station, and it was noted in England on 4785 kHz in 1953.  This station, with 1 kW on 1394 kHz, was finally closed in January 1966.

A third BFBS station located at Tobruk came on the radio scene considerably later than the previous two.  It was inaugurated in July 1964, and radiated 1 kW on two channels, 1439 & 1484 kHz (208 and 202 meters), as well as on 89 MHz FM.

Interestingly, the programming from the Tobruk BFBS station was also relayed over an FM transmitter on 90.2 MHz at El Adem, 17 miles inland, which received its program feed via a landline connection.  The Tobruk station was closed after six years of service in 1970.

BFBS in Libya was therefore on the air on shortwave from two different locations, Benghazi in 1947, 1949 & 1956; and from Tripoli in 1953.  And yes, these BFBS stations in Libya did issue QSL cards, though these days they are quite rare.  Dr. Adrian Peterson’s Heritage Collection does contain one such card, verifying BFBS Benghazi on shortwave with 4 kW on 3305 kHz in 1954.

From 1943 to 1970, the United States Air Force operated the Wheelus Air Base on the coast near Tripoli, a facility that had originally been constructed by the Italian Royal Air Force in 1923.  On the base there was an American AFRTS station, both radio and TV, and it appears from listings in the WRTH that the radio station was first launched in 1954 with 100 watts on 1510 kHz.  The TV station was added early in 1955.  Very little is known about either station; they must have had American callsigns, but what they were, we don’t know.  When they were closed in 1970, the radio station was operating with 1 kW on 1594 kHz.

The significance of the closure in 1970 of both BFBS Tobruk and AFRTS Tripoli is that it was on September 1st, 1969 that King Idris I was overthrown by Muammar Gaddafi in a successful military coup d’état.  Before the revolution, the US and Libya had already reached agreement on US withdrawal from Wheelus.  This proceeded according to plan, and the facility was turned over to the new Libyan authorities on 11th  June 1970.

Next week, we’ll take a look at the domestic governmental radio operations in Libya, on both medium wave and short ave.

Back to you, Jeff.

The Zenith Radio Story - Part 1

 

Jeff: Recently, Wavescan listener Vince Koepke sent us a pdf copy of a brochure produced by the Zenith Radio Corporation in 1955, detailing some of the early history of the company.  If you’ve ever been lucky enough to own a Zenith Trans-Oceanic receiver, you’ll know how important this company was to the shortwave listening audience.  The brochure makes for fascinating reading, and so we’ve decided to serialize it over a few weeks here in the broadcast.  This week, Ray Robinson has the first part, covering from the very early days up until the early 1920’s.

Ray:  Thanks, Jeff.  The history of Zenith was to a considerable degree a history of the radio-television industry in the United States.  This was so because Zenith was a pioneer and leader in radionics since before there was a radio industry, and it played an important role in almost every important development during radio growth from an amateur toy to the most significant, widespread, and effective system of communications in history.

On December 14, 1901, Guglielmo Marconi flashed the letter “S” across the Atlantic Ocean by wireless telegraph, and thereby launched a revolution in communications that was destined to bring profound changes in the pattern of civilization. Marconi’s tremendous achievement brought only passing attention from the adult public, but it kindled the imagination of eager youngsters everywhere.  In the decade that followed, many of these youngsters dismayed their parents by devoting more time and effort to “Marconi’s toy” than to preparing themselves for a future in “something practical”.

Beginnings 
Two of these “wireless doodlers” lived hundreds of miles apart, and were to meet only by sheer chance.  R.H.G. Mathews of Chicago pursued the hobby and qualified as an amateur radio operator in 1912.  In 1915 he began building and selling wireless equipment to other amateurs.  Karl Hassel of Sharpsville, PA, won his amateur license in 1915, and then matriculated at the University of Pittsburgh.  Here he discovered that he was the only person on the campus, student or faculty, who knew how to operate the University’s newly constructed wireless station.

Came World War I, and both boys enlisted in the Navy.  They met at Great Lakes Naval Training Station, and worked together on radio until 1918.  They then set up a continuation of Mathews’ business as Chicago Radio Laboratory, building and selling radio sets.

Their first factory was a table in Mathews’ kitchen.  Their tools were pliers, screwdrivers, a hand drill, and a soldering iron that had to be heated over the burner of a gas stove.  From this kitchen table workshop grew the business that was to become Zenith Radio Corporation.

Early in their business life Mathews and Hassel began a long series of radio “firsts” that became a Zenith tradition.  One of their first ventures was construction of a longwave radio receiver for the Chicago Tribune, which was used to pick up news dispatches about the Versailles Peace Conference from a longwave station in France.  This short circuiting of the congested trans-Atlantic cable enabled the Tribune to beat competitors by 12 to 24 hours on conference stories.

The varnish had scarcely dried on the kitchen table workbench before the fledgling business needed larger quarters.  The boys built a new factory near the Edgewater Beach Hotel.  It was a shanty-like structure that gave them a working space of 14 by 18 feet, with a cubby hole for their amateur radio station, 9ZN.  At about the same time they published their first catalogue.  A few months later they coined the trade name, Z-Nith, from the call letters of their radio station.  This was the origin of the trade mark, Zenith.

The next Z-Nith first was construction and installation of a wireless system that made the Nashville, Chattanooga & St. Louis Railway the first railroad in the world to successfully dispatch trains by wireless telegraph.  Transmitters and receivers were set up in Tullahoma, TN and Guntersville, AL to handle traffic over the rough country between.

Initial difficulties included such things as the transmitters setting off a bank’s burglar alarm during a directors’ meeting; adding a high voltage shock to the pain of a dentist’s drill while he was working on a touchy patient; and putting nearby telephones out of service.  These problems were ironed out.  The system went into service, and operated successfully for several years.

By the end of 1919, the Z-Nith partnership was thriving, with production exceeding one complete set per week.  In May, 1920, the boys acquired their most important asset, a license to use the basic regenerative circuit patent of radio’s greatest inventive genius, the late Major Edwin H.  Armstrong.

Until the latter part of 1920, Chicago Radio Laboratory concentrated on building equipment for the growing army of radio amateurs, or “hams” as they soon came to be known.  A change came in November of that year.  Radio broadcasting as we know it today was non-existent.  The University of Wisconsin had begun in 1919 a regular broadcast schedule of news, market reports, weather information, and general programs from its station 9XN (now WHA, which has been licensed to the University of Wisconsin since 1922 and still broadcasts Wisconsin Public Radio 102 years later on 970 AM).

Initially as a public service for radio amateurs, WHA developed a unique program.  Each noon it radio-telegraphed the weather report in fast code for expert “hams”.  The report was then repeated in slow code so that beginners could take it.  After that, an announcer read the weather report for the general public, and so that beginner “hams” could check their accuracy.

Here and there around the country other stations produced similar schedules, but only a narrow segment of the public showed interest.

Then came the presidential election of 1920.  News of the Harding landslide was disseminated with startling speed throughout the country by station KDKA in Pitts- burgh and other stations.  The public suddenly realized that Marconi's toy was a very useful and practical communications tool.  Broadcasting began in earnest.
Hassel and Mathews quickly put on the market a receiver with which the general public could hear the growing number of broadcasts.  Business boomed, and within a few months the walls of Chicago Radio Laboratory's new factory were bulging.  So the company moved to a mammoth 3,000 square foot plant on Ravenswood Avenue, with a staggering rental of $300 per month, and a payroll of six employees.  At this time the boys bought their first power tool, a motor-driven drill press, and boosted production to more than one set per day.

McDonald Joins the Partnership 
In the meantime, E.F. McDonald, Jr., of Syracuse, NY, had established himself in the automobile business in Chicago, where he introduced the first successful plan for selling automobiles on time payments.  He had served through the war in Naval Intelligence and been discharged with the rank of Lieutenant-Commander; and was looking around for a new business.

On New Year’s Eve, 1920, McDonald went to a garage to pick up his automobile, and noticed several men listening to music coming from a box.  He asked the proprietor what there was about this phonograph to make people listen to it on New Year’s Eve.

“That is no phonograph,” he was told.  “That is a radio.  They are listening to music through the air from Pittsburgh.”

McDonald learned that it would take several months to get delivery on a radio set for himself, and decided he had found his new business for which he had been searching since the end of the war.  However, it was not that simple.  He found out that he would need a license to use the inventions of Major E.  H.  Armstrong, and Armstrong licenses were no longer available.

Temporarily balked, McDonald soon heard about two young men — Hassel and Mathews — who were building radio receivers on Chicago’s north side.

Thinking about that radio set, he paid a visit to the Ravenswood factory and took particular fancy to a set that sold for $75.00, less tubes, batteries, and headphones.  Hassel, in person, came to McDonald’s residence at the Illinois Athletic Club to install it—and didn't leave until he had collected his money.  Recalling the occasion, Hassel said, “It wasn’t a question of whether I trusted him or not—we needed the money to keep going.”

Hassel and Mathews had the all-important Armstrong license, and more business than they could handle with the equipment they owned.  But they were short on capital.  McDonald joined forces with them, provided funds for expansion, and became general manager of Chicago Radio Laboratory.  One of his first moves was to change the trade mark from Z-Nith to Zenith.

Normally, capital investment in an existing business results in an equity for the investor.  In this case, however, the largest investor, McDonald, owned no interest whatsoever in Chicago Radio Laboratory, and for a very good reason.  The Armstrong license was held by Chicago Radio Laboratory, a co-partnership, and was not transferable.  This also had its bearing on the organization of Zenith Radio Corporation.  When that company was formed in 1923 it was not a manufacturer.  Instead, it was the exclusive sales and marketing organization for handling the radio equipment built by Chicago Radio Laboratory.  This arrangement continued until other developments made a consolidation possible, at which time the entire assets and business of Chicago Radio Laboratory were acquired and Zenith became a manufacturer in its own name.

And that’s where we have to leave the Zenith story this week.  We’ll continue with Part 2 in a few weeks’ time.  Back to you, Jeff.

Update on Myanmar's Thazin Radio

 

Myanmar - Thazin Radio has been silent on shortwave since April 7, 2024.

It seems shortwave transmitter Pyin Oo Lwin is having a bit of trouble. However, I caught them tuning in on 639 kHz just now, at 13:00 UTC, mingling with a Thai station. Thazin Radio is part of the Myawaddy Communication Center and is owned by the military in Myanmar. It's financed by Myanmar Economic Holdings Limited (MEHL), which is a conglomerate owned by the military.

Myanmar - Thazin Radio from Pyin Oo Lwin site on 7345 kHz.

12.40 past 13.15 UT in vernacular. Lots of popular songs. Am I the only listener noticed improved signals from Thazin Radio. Has this station operated by Tatmadaw, upgraded its tramsmitter out put and the antenna system?
(Sarath Werakoon-Mt. Lavinia-CLN  4S5SL, via wwdxc BC-DX TopNews April 2)

Pyin Oo Lwin of Myawaddy Radio center built in 2007 to 2008 years, some 208 far away kilometers north of new capital Nay Pyi Daw. Location is at  22 00 57.41 N  96 33 00.48 E or 22.01741925751829 N  96.55174262265729 E  northerly point in Myanmar.

Thazin Radio from Pyin Oo Lwin. I don't know the reason why Japanese Aoki Nagoya group circle recently put the 208 kilometers distant location - capital name - Nay Pyi Daw on their SW frequency database - for a year now, i.e. 6165, 7345, and 9590 kHz requested channels ?

KTWR DRM schedule update

 

GUAM    
KTWR DRM A24 - Updated - Both India blocks are on 15390 kHz.

We have good news for you. KTWR is maintaining the current amount of time for DRM broadcasts for the A24 broadcast season. The only timing change is that the two Sunday blocks will have no gap between them. The South Indian language broadcasts will start 15 minutes earlier than they do in the B23
season. The end time will also be earlier.

We are grateful for your reception reports. The posts on WhatsApp have been quite helpful. It will be interesting to see how 19 meters performs in India. We have seen some intermittent multipath issues with 22 meters in parts of India.

Radio History from Gibraltar

 



Special thanks to Ray Robinson and Jeff White for sharing a recent edition of Wavescan on AWR.

Radio History from Gibraltar
Jeff:  Today Ray Robinson tackles a topic we’ve never covered before here in Wavescan – the history of radio broadcasting in the tiny British Overseas Territory of Gibraltar.  So, in Los Angeles, here’s Ray.

Ray: Thanks, Jeff.  Gibraltar is a small peninsula attached to the south coast of Spain, which juts out into the Mediterranean.  It is just 1½ miles long north to south, and ¾ mile wide, much of which is occupied by the famous Rock itself.  With its commanding position overlooking the strait between Spain and Morocco through which all shipping between the Mediterranean and the Atlantic must pass, Gibraltar is of great strategic importance, and its sovereignty has been contested by the Spanish for centuries.

Gibraltar was first permanently settled by the Moors in the 6th century, and was renamed Jebel Tariq, meaning Mount of Tariq, which was later corrupted into the name Gibraltar.

Gibraltar was besieged and conquered by Spain in 1462, and it remained part of the unified Kingdom of Spain for 242 years from 1462 until 1704.  It was then captured by the Anglo-Dutch Navy during the War of the Spanish Succession, and was formally ceded to Great Britain in the Treaty of Utrecht in 1713 in exchange for territorial concessions in North America.  And for the last 320 years, it has remained under British control.

At the foot of the Rock on the western side there is a densely populated town area with narrow streets, which these days is home to a permanent resident population of about 32,000 people.  Gibraltar was formally recognized as a city by Queen Victoria in 1842.  Historically, much of the local economy was dependent on the naval port, but these days most of their income is derived from tourism (aided by a new cruise ship terminal), online gambling and offshore financial services.

Before the Second World War, a local private company had set up 'Radio Distribution', which relayed the BBC Overseas Service via cable from 301 Main Street. But as the clouds of war approached, Radio Distribution came under the control of the British Ministry of Information, and was run by the Royal Corps of Signals.

As from 1941, Radio Distribution was based at Wellington Front, an area that was to become the home for broadcasting on The Rock for three decades.

A new 'Radio Gibraltar' was also set up by the Ministry of Information for the civilian population.  Initially, its local content was minimal, but it did include announcement of the Gibraltar lottery results!  During the war, the transmitter was moved to Morocco, to play its part in Operation Torch - the allied invasion of North Africa.  Gibraltar was then served by a smaller 250 watt transmitter based at Wellington Front.

When the war ended, the need for information on The Rock was deemed less important by the Ministry, and by August 1945, the early version of Radio Gibraltar was phased out.

In the aftermath of the Second World War, Gibraltar was essentially a garrison town, its society finding its way after the evacuation and return of its civilian community to The Rock.  The Spanish language predominated, and local culture strove to make sense of its own identity.  Initially, a one-hour daily program was recorded in Gibraltar for the local residents, and this was broadcast by Pan American Radio from 5-6pm through the medium wave transmitter of Radio Tangier in Morocco, just across the strait.

It wasn't until 1957 that the local government in Gibraltar once again felt the need for a full-blown local information and entertainment service of their own.  Known also as Radio Gibraltar, it was the brainchild of Sir Howard Davis, and was managed and operated by British civil servants, with technical help from the Royal Corps of Signals.  The station launched at 11:50am on Sunday, 16th February 1958 with 1 kW on 1484 kHz (202 metres).  Daily programs were in English from 8am to 3pm, and 6pm to 11pm, partially funded by commercials.  Top of the hour newscasts were again relayed from the BBC Overseas Service, and other BBC programming was carried also.  Afternoon programming in Spanish was added later.

Using some very basic equipment, black and white television transmissions began from Signal Hill (at the southern end of The Rock) on VHF channel 12, in October 1962.  A locally controlled broadcasting service became increasingly important, so in December 1963, the Gibraltar Broadcasting Corporation was established, to take over the operation of both the radio and TV services on behalf of the Gibraltar government.

In June 1969, General Franco of Spain ordered the frontier with Gibraltar to be closed, and it remained closed for 13 years.  My family and I were fortunate to be able to live and work in Gibraltar for five months in 1980 & 1981, and it was sad to see the guards on the Gibraltar side of the border ceremoniously opening the gates every morning, and then closing them again every evening, while the gates on the Spanish side remained resolutely closed.  After we left, the border was partially reopened to pedestrians only in December 1982, and then finally fully reopened to vehicular traffic as well in February 1985.

Throughout the 70's during the period of the border closure, Radio Gibraltar also relayed BBC programming from London in Spanish, and this was much appreciated during the Franco years by the residents of La Liñea, San Roque, Algeciras, along the Costa del Sol and in other towns in the hinterland close to Gibraltar (known as the 'Campo').  It is said that walking through those towns in the afternoons, one could often hear "This is the BBC from London broadcasting to Spain on shortwave", coming from radios tuned to Radio Gibraltar on 202 metres.  In Spain at the time, it was actually forbidden to listen to the BBC from London!

The programs of record requests and dedications then also became an important means of maintaining contact for people with family members on both sides of the border.

In November 1978, Radio Gibraltar's transmitter was given a power increase to 2 kW and moved from 1484 to 1458 kHz (206m), the medium wave frequency it still uses to this day.  In 2014 it was given another power boost, this time to 4 kW.  Due to reception challenges close in around the Rock, however, two stereo FM frequencies were added in the 1980's - on 100.5 MHz with 1 kW, and on 91.3 MHz with 250 watts.  Some years later, a third FM transmitter was added on 92.6 MHz, also with 1 kW. 
The 1980's also saw both the GBC radio and television operations move from the rather dilapidated building at Wellington Front to new studios called Broadcasting House on South Barrack Road at the southern end of The Rock.

Until the early 80's, programming was typically in short blocks of 15 or 30 minutes covering many different musical genres including classical and opera as well as contemporary pop.  However, a restructuring then took place, and the more familiar two or three hour shows with contemporary music similar to many local independent stations in the UK was adopted.  Peter Canessa was the presenter of a lunchtime show called 'A Bit of Alright', and here he is at 1pm on Tuesday 8th June 1982:

I recorded that myself while on vacation on the Costa del Sol.  Three days later, I also recorded David Hoare with the station sign-on at 6:45am, on Friday 11th June 1982:

To serve the small military community, the British Forces Broadcasting Service (BFBS) opened a station in Gibraltar in the 1960's.  This has only ever broadcast on FM, originally on 93.5 MHz with 250 watts.  In the late 70's, a second frequency was added on 97.8 MHz, and both of those can still be heard today.  Programming is a mixture of locally produced shows and network shows relayed from London.

Here's the start of the 8:30am news headlines on BFBS with presenter Claire Riley, later the same morning as the GBC sign-on we just heard:

Since the mid-2000's, both GBC Radio Gibraltar and BFBS Gibraltar have been streaming their programming online, so if you want to catch up with them through an Internet Radio or web browser, it's pretty easy.

Back to you, Jeff.

Tangier International Zone - Part 1

 


Special thanks to Ray Robinson and Jeff White for sharing a recent edition of Wavescan on AWR.


Jeff: A couple of times recently, broadcasting from Tangier in Morocco has been mentioned in other topics.  A few weeks back in his item on radio broadcasting from Gibraltar, Ray Robinson noted that before Radio Gibraltar was set up in 1957, a one-hour daily program for Gibraltar had been broadcast by Pan American Radio via Radio Tangier, just across the strait.  Also, in one of the items on Sweden, it was noted that IBRA radio began by buying time on a station in Tangier.  So, Ray’s been digging into just what exactly was the broadcasting situation in Tangier during the 1940’s and 50’s, and it has turned out to be quite a fascinating story.  Here he is now, to tell us all about it.

Ray: Thanks, Jeff.  The history of Morocco on the northwest coast of the continent of Africa is long and eventful going back thousands of years.  For our purposes, we can note that during the 1800’s it had been ruled from Istanbul as part of the Ottoman Empire, although after the Napoleonic wars it became increasingly difficult to govern.  The French and the Spanish were both strongly interested in the territory which was nominally ruled by a Sultan.  But by 1900, it had become the scene of multiple local wars started by pretenders to the sultanate, by bankruptcy of the treasury, and by multiple tribal revolts.  The French had conquered neighboring Algeria in the 1840’s, and sensed an opportunity to expand their influence in the region.  They used both diplomacy and military force, and effectively took full control of Morocco in 1906.

Tensions rose between France and Spain, however, and in 1912, a treaty was signed by both the French and Spanish heads of state, which granted Spain a zone of influence in northern Morocco, which became known as the Spanish Protectorate of Morocco.  The remainder of the country, including the important cities of Fez, Casablanca, Marakesh and Rabat, became the French Protectorate of Morocco.

Both France and Spain wanted to control Tangier, a port city on the most northerly point of Morocco, which has the best harbor on the western end of the North African coast.  But the United Kingdom wanted to neutralize the city, to maintain its dominance of the Strait of Gibraltar.  Tangier looks out across the Strait to Tarifa, Spain, just 20 miles away, and has long been viewed as both the Gateway to the Mediterranean, and indeed to Africa as well.  So, it was agreed that Tangier would be granted special status, but the details of that status were not fully worked out until after World War I had started in 1914.  Then, while the attentions of the leaders of Britain and France were focused elsewhere, Spain used the opportunity to delay implementation.

Negotiations restarted after the war, and a new treaty was eventually signed by France, Spain and the UK in 1923 making Tangier a neutral zone under joint administration.  The Zone went into effect on 1st June 1925.  It had an area of 155 square miles, centered on the city of Tangier, and it was to be entirely free of any military presence.  It was also made into a tax haven , with no tariffs on imported or exported goods or gold, no exchange controls, no income or revenue taxes, and unlimited freedom of establishment (meaning no restrictions on the ability to set up businesses).  And for our purposes, we should note that there were no controls on radio broadcasting – no licensing was required.  The Zone had its own flag, defence force, police, and legislature.  Several currencies were accepted, but the official one was the Pound Sterling.  And Britain, France and Spain each provided their own postal services in the Zone.

The first edition of the World Radio Handbook was published in 1947, and that lists just two radio stations in the French Protectorate, in Rabat and Casablanca.  They both provided programming in French and Arabic, and operated transmitters on medium wave for coverage of the local city areas, and on shortwave for the north African region.

In the Spanish Protectorate, there is just one station listed, in Tetuan, with 20 kW on 6070 kHz shortwave.  All programming was in Spanish. 

It is likely that these stations were first implemented in the 1930’s, and continued during and after World War II.

In the Tangier International Zone, however, there is no known radio broadcasting activity prior to the war.

On 14th June 1940, the same day that Paris fell to the Nazis, Spanish troops occupied Tangier, using the pretext that they were protecting the city from the risk of an Italian or German invasion.  From then until 1945, Tangier effectively became part of the Spanish Protectorate, but after the war, Spain was forced to withdraw, and the International Zone was reinstated, with the United States joining the joint administration.

After the war, two main radio stations were set up in Tangier with the goal of broadcasting unregulated programming into Spain.  One was pro-Franco, and the other was anti-Franco.  The anti-Franco one came first.

In the mid-1930's, Herbert Rutledge Southworth was a left-wing socialist journalist working at the Library of Congress in Washington, D.C.  When the Spanish Civil War broke out in 1936, he began to review books on the conflict for the Washington Post.  He was emotionally affected by the struggle between fascism and anti-fascism, and wrote press articles and pamphlets with passion.  He was devastated by the defeat of the Spanish Republic although, after the Civil War ended, he continued to work for the exiled former premier Juan Negrín.  Then, shortly after the attack on Pearl Harbor, Herbert was recruited by the U.S. Office of War Information.  In 1943, he was sent to Algeria to work for the Office of Psychological Warfare.  Because of his knowledge of the Spanish situation, he was posted to Rabat in the French Protectorate of Morocco to direct Spanish-language broadcasts to Franco's Spain.

At the end of the war, he decided not to use his demobilization air passage home but to stay in Rabat.  Knowing that there were no controls on broadcasting from Tangier, he bought a quantity of U.S. Army surplus radio equipment with which he founded Radio Tanger Internationale (Radio Tangier International).  He broadcast with 10 kW on 244 metres (1230 kHz), and with 1 kW on 6200 kHz shortwave, with programming in French, Spanish, Arabic and English.  His primary purpose was to expose what he saw as some of the lies perpetuated by the Franco administration in Spain.  This was taking quite a risk, because Tangier was surrounded by the Spanish Protectorate in Morocco, where General Franco had a strong base of support.  Indeed, it was from there that he had launched his military coup against the Republican government in Madrid in 1936.  To cover the operating expenses of the station, Southworth accepted commercials and sponsored religious programs, with one of the first being ‘Bringing Christ to the Nations’ in French, Spanish and English on Sunday mornings.

The other station was founded by Jacques Trémoulet, a figure well-known in European radio circles before the war.  As early as 1925 he had established Radio Toulouse, which became one of the strongest private stations in France up until the Second World War.  In 1939 he had also set up Radio Andorra.  Toulouse, being in southern France, was in the area controlled by the Vichy government, and he was forced to carry official information and propaganda on behalf of the Vichy government over his radio station.  When the Vichy government fell, Jacques Trémoulet was accused of collaboration, and his property was confiscated.  He fled, first to Andorra, and then on to Spain.  He was tried in absentia and sentenced to death, although he was later acquitted on appeal.

In Spain he set up Radio Intercontinental Madrid, and then moved on to Tangier in 1947, where another of his stations appeared, Radio Africa, which broadcast in Spanish, French and Arabic with 1 kW on 7080 and 14280 kHz shortwave.  Their programming was mainly music, supported by commercials.  So whereas Radio Tangier International was anti-Franco, Radio Africa was very much pro-Franco.

Well, that’s all I have time for this week – we’ll continue the Tangier International Zone story in two weeks’ time.  Back to you, Jeff.

Highlights of Solar and Geomagnetic Activity 08 - 14 April 2024

Solar activity reached high levels on 11 Apr due to an M5.4 flare at 11/1706 UTC from Region 3637 (S12, L=231, class/area=Cso/40 on 14 Apr); the largest event of the period. Moderate levels of solar activity were observed on 13-14 Apr due to an M2.4 flare at 13/0502 UTC and an M4.3 flare at 14/0232 UTC from Region 3637. The remainder of the period saw low levels of solar activity with C-class flares observed. Two CMEs, associated with filament eruptions near N20E02 at 11/0600 UTC and S16W14 at 12/0020 UTC, were anticipated to arrive on 14 Apr, but ultimately were not detected in the solar wind by the end of 14 Apr. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal to moderate levels throughout the week. 

Geomagnetic field activity was quiet to unsettled over 08-10 Apr due to positive polarity CH HSS influences. Quiet and unsettled levels were observed over 11-12 Apr, and quiet levels were observed over 13-14 Apr, as CH HSS influences subsided and nominal solar wind conditions returned. 

Forecast of Solar and Geomagnetic Activity 15 April - 11 May 2024

Solar activity is expected to be at low to moderate levels throughout the outlook period, with C-class flare activity expected and a varying chance for M-class flare activity. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels throughout the period. 

Geomagnetic field activity is likely to reach G1 (Minor) storm levels on 15 Apr due to CH HSS influences and CME effects. Quiet and quiet to unsettled levels are expected to prevail throughout the remainder of the period.

PUBLISHED: APRIL 9, 2024

A Saturday session of the Broadcast Engineering & IT Conference will explore “Using Drones to Verify FM Antenna Performance.”

John Schadler is vice president of engineering for Dielectric LLC, which makes antennas, RF systems components, and transmission lines. Jason Schreiber is managing director of Sixarms, which uses drones to provide measurement solutions for broadcasters and other industries. 

Radio World: What is your session about?

John Schadler: The paper will discuss the power of computer simulation and validate the predictions through comparisons to drone measurements. This in turn also shows the ability drone measurements have to verify antenna system performance.
