Trans World Radio, B-25 Winter -English
Wednesday, September 18, 2024
50 years of the Roumoules transmitter in Haute Provence, France.
Former RMC's LW 216 kHz. But still TWR on MW 1467 kHz.
TWR (Trans World Radio) is commemorating a significant milestone today: the 50th anniversary of broadcasts from the Roumoules radio station. These broadcasts have enabled the gospel message to reach countless listeners across borders and barriers.
In 1960, TWR began airing from a 100-kilowatt shortwave transmitter in Monte Carlo. At that time, audio tapes had to be physically delivered to transmitter sites. On occasion, they even had to be smuggled across national borders to Monte Carlo for transmission back into the originating countries. This is considered TWR's first transmitting site under the name Trans World Radio.

From War Propaganda to Gospel Outreach: The Story of Trans World Radio Monte Carlo

The small European country of Monaco is located against the Mediterranean coast of France, just ten miles from the border of Italy. This country is listed as the second smallest in the world, with only the Vatican being smaller. Monaco is a little more than two miles long, and at its narrowest point it is only 200 yards wide. The total area is just ¾ square mile, and almost a quarter of this total area has been recovered from the Mediterranean Sea.
The capital city of Monaco is, Monaco; though another well known city in this tiny enclave is Monte Carlo. The total population of all of the country of Monaco is around 33,000. The country obtains much of its revenue from tourism, with 1½ million people flooding into the area each year.
Their national flag shows a plain red banner on the top half and a plain white banner on the bottom half. Surprisingly, the Monaco flag is exactly the same as the flag of both Indonesia & the German state of Hesse, though the dimensions are slightly different.
The country of Monaco is also well known for its Casino; and the Monaco Grand Prix car race; and its Tour de France bicycle race. Monaco issues its own colorful postage stamps, and also its own coinage, now in the Euro series.
It was back in the year 1956, that the American Hollywood actress Grace Kelly married Prince Rainier in a highly publicized wedding ceremony. The reigning Grimaldi family traces their dynasty back to the year 1297, when the first of their clan took over the throne.
This little southern European country was named by Greek seafarers who set up their own colony around the 600s. Another 600 years later, and the area was refounded as an Italian colony dependent upon the city of Genoa. Even though Monaco is an independent country, it is heavily dependent upon neighboring France.
It was back in the year 1923 that initial consideration was given to establishing a radio station in Monaco, though nothing definite came of this matter until some 20 years later. During the year 1942, discussions for the establishment of a new international shortwave station took place between the government of Monaco, and the governments of both Germany & Vichy France. In May, a permit was issued for the construction of a powerful shortwave station that could give wide area coverage to German radio programming.
Work on the new station moved slowly, though two shortwave transmitters, rated at 100 kW each, were ordered through the Indonesian government. A new transmitter building was constructed into the side of Mt Agel, behind Monte Carlo, and located actually in what is officially French territory.
A temporary radio station was inaugurated in an official opening ceremony on July 17, 1943, with the well known French actor, Maurice Chevalier as the Host of Ceremonies. A small shortwave transmitter with just 200 watts was located in Monaco itself, and the mediumwave outlet was the already established transmitter of Radio Mediterranee on 1240 kHz which was located some distance away at Antibes in France. A little over a year later, this new Radio Monte Carlo was closed.
In June 1945, Radio Monte Carlo was re-opened by the French, with a 300 watt shortwave transmitter on 6130 kHz; and a year later, a 10 kW mediumwave transmitter on 410 metres, 730 kHz. Both of these units were heard by international radio monitors in England. One year later again, a 25 kW shortwave transmitter was installed and this was noted on air in the United States, as well as in New Zealand & Australia.
On two different occasions, Adventist radio programming was noted over Radio Monte Carlo. Beginning in 1957 and for a year or two, the French version of the “Voice of Prophecy” was heard on three shortwave channels; and for a few months in 1999, Adventist World Radio took out a relay via the mediumwave transmitter on 702 kHz for coverage into North Africa in both Arabic & French.
In 1958, Trans World Radio signed a contract with Radio Monte Carlo for the establishment of a large shortwave station, and the transmitters would be installed in the disused building constructed into the side of Mt Agel during the German era. Trans World Radio was on the air previously from a site in Tangier, North Africa, but, with the changing political scene in Tangier-Morocco, it became necessary for them to re-locate elsewhere.
The new facility for TWR Monte Carlo was inaugurated on October 16, 1960, with the use of a new 100 kW shortwave transmitter under the official callsign 3AM5. An additional 100 kW shortwave transmitter was installed during the following year, and a 500 kW transmitter in 1982. Their studios and offices occupied three floors in a multi-storeyed building in Monte Carlo.
At the height of their operation in Monte Carlo, TWR was on the air from the three shortwave transmitters and ten curtain antennas, as well as on mediumwave from a high powered facility nearby. The main antenna systems are located in French territory rented to Monte Carlo, though one antenna for coverage into Europe is located on the northern slopes of Mt Agel in what is regular French territory.
These days, with the usage of their own shortwave stations elsewhere, as well as with rental time on additional relay stations, the TWR station in Monte Carlo is in part time use only, just for the morning hours on the two 100 kW transmitters.
QSLs from Radio Monte Carlo are quite evident, and multitudes of QSL cards have been issued over the years by Trans World Radio Monte Carlo.

U.S.-Based Shortwave Broadcasters Eye Digital
JAMES CARELESS, 26 August 2019
Relatively few Americans are aware of it, but the United States is home to many ommercial/religious international broadcasters that transmit programming worldwide using analog shortwave radio transmitters. They are supported by an industry group called the National Association of Shortwave Broadcasters.
Unfortunately, analog shortwave radio transmissions are notorious for interference and signal dropouts. For listeners in other countries, the sound coming out of their shortwave radios lacks the superior audio range of domestic U.S. AM (yes, we said AM) and is often wracked with static and signal fading.

As War Rages, Syrians Find Hope on Radio
Now a radio program launched this summer is providing a forum for Christians and non-Christians to tell their stories amid the violence and deprivation. They are offering and receiving advice and encouragement on the TWR broadcast of Hope for Syria.
Much like Joseph told his brothers as they groveled before him in ancient Egypt, God can bring good out of these circumstances despite the obvious horrors inherent in the bitter war and religious strife. Through Hope in Syria, says TWR’s Arabic Ministry director, “the Lord strengthens the faith of those who are experiencing hunger and seeing their kids suffer.”

TWR replaces Creole with Spanish at night
Gayle VH
In a blog post dated Friday 6 August, TWR Bonaire’s Brand Swanson writes:
“We’ve been broadcasting late night programming, in Creole, to the island of Haiti, since the big earthquake there last year [sic]. Now that the local Christian radio stations are back in full swing, we don’t need to use the Bonaire transmitter to reach Haiti. So starting this past Monday night [2 August] we’ve begun to transmit a new package of music and Spanish language programs from our RTM partners in the region.
“We haven’t been on the air straight through the night for quite a number of years now, but we used to have a large late night audience and I’m hoping and praying that listeners will quickly find us again. There are a bunch of other great RTM programs in our late night lineup as well. You can even hear some of them online sometimes, when the Venezuela and Uruguay offices have their streaming audio feeds running.”
TWR broadcasts on mediumwave 800 kHz.

"We also recognize the tremendous ministry value of social media portals like Facebook, Twitter and YouTube," Libby adds. "We're not just endeavoring to reach people for Christ; we want to connect and dialogue with them as they grow in faith. Furthermore, we realize social media is a fast and efficient way to communicate with our stakeholders."
