A Story of Radio RSA (2): Early Days at Bloemendal Transmitter Site
Most shortwave listeners outside South Africa, provided that they were teenagers or older in the 1970s and 1980s, will think of Radio RSA when South African radio is mentioned. But Radio RSA’s parent organisation, the South African Broadcasting Corporation (SABC) was founded in 1936, and some early broadcasting seems to have taken place as early as in the 1920s.

According to Orlik1, South Africa’s first steps into international broadcasting started in 1950, only two years after the National Party, the one that implemented the apartheid policy that would determine South African politics for more than four decades, had come to power. Around 1950, a small shortwave station with only one transmitter was built in Voortrekkerhoogte, southwestern Pretoria2 and / or in Welgedacht, and in early 1957, a much larger station went into operation in Paradys, southwest of Bloemfontein.
From the 1960s onward, South Africa was at odds with most of the world as far as its apartheid policy was concerned. At the same time, interest in isolating it economically was limited, certainly in Western countries. And despite much of the All-African rhetoric, South Africa’s degree of isolation in its neighborhood, on the African continent, varied, too.
The Non-Aligned Movement – with the exception of countries on the African continent – appears to have been regarded as a lot of lost souls by the South African Broadcasting Corporation (SABC), the parent organization of Radio RSA. China and the USSR weren’t heavyweight trading partners anyway.
And if it was up to many or most of the National Party politicians, that was nothing to be hurting of. According to Ake Magnusson3, a researcher with Gothenburg University in the 1970s, the second man in charge of the Bloemendal shortwave project was Albert Hertzog, telecommunications minister in the Nationalist Party cabinet. His boss was Hendrik F. Verwoerd, South Africa’s prime minister. Neither of them was quite the liberal.
Two years after Radio RSA had gotten started from Bloemendal, the SABC wrote4:
All that remains to be added are broadcasts to Latin America and the Far East. These transmissions have already been planned but it will be some time before they are put into effect."
Radio RSA did add Latin America and – for some time – Australia and New Zealand to its target areas during the years or decades that followed, but as far as I can tell, there never were any dedicated Radio RSA transmissions to or language services for China, India or Indonesia.
Western or West-leaning countries were apparently deemed to be the propaganda battlefield. As Magnusson noted, "politically as well as economically Europe and North America are more important to South Africa at short sight than for instance Latin America and the Asian states."
In 1971 nearly 45% of the programme time was devoted to working on and disseminating information to the politically important states in North America, Europe, Australia and New Zealand. These nations are South Africa’s interchagne partners. Trade, investments and immigrants form South Africa’s umbilical cord to the outside world and the placenta was, and still is, formed by several „western“ countries. The Third World and the Communist states had begotten and were still actively nourishing the strategy of isolating South Africa from the outside world. In order to prevent this strategy from being put into political practice South Africa is working on the Western Powers energetically. An element in this work is made out by shortwave broadcasts to the countries mentioned."
Prime Minister Verwoerd pushed the inagural button on October 27, 1965 at what was soon to become the H. F. Verwoerd Shortwave Station, after the Verwoerd’s assassination a year later. The transmitters‘ location was at Bloemendal, near Meyerton, Gauteng Province.
It is said that there were four transmitters at 250 kW each5 in Bloemendal at the time, that could be taken on the air on May 1 1966 when Radio RSA officially went into operation with its first schedule. Based on this source, this is what Radio RSA’s schedule from November 1966 to March 1967 looked like.
The bar chart shows three target areas: Africa, the Middle East, Europe, and North America. Africa is targeted with 94 hours weekly, while the Middle East gets only one hour per week. Europe is at six hours, and North America is at 26. Based on data by Magnusson.6
It seems that Europe was actually the SABC’s or Radio RSA’s first target area outside Africa7. That would make sense for a number of technical reasons (I’m guessing here). When we look at an azimuthal map, Europe didn’t require a beam range as wide as North America.
Working hours may have played a small role, too: the time difference between (western) Europe and South Africa was minimal. A continuity announcer for this audience, if live on air, would be at the microphone in the early evening hours South African time. At least some of the continuity was indeed spoken live. Also, it was hoped that some of the transmissions for Europe could be heard in North America, too.8 Either way, South African radio became much easier to „DX“, and even to simply listen to, than before 1966.
Adrian Peterson, father of the „Wavescan“ programs, gave a detailed technical account of the shortwave transmitter site when Sentech put it off air in 2019.
Entering the coordinates of 26°35’34.0″S 28°08’24.0″E at Google Maps should still take you to a rather instructive aerial view of the station at Bloemendal, some ten kilometers east of Meyerton, and some 40 kilometers south of Johannesburg (both beeline distance). The coordinates 26°35’10.6″S 28°08’21.6″E will take you to the cake-tin shaped switchhouse where Radio RSA’s first internationally-dedicated four Brown-Boveri transmitters would be connected to any of the station’s 38 antenna arrays by the push of a button9. From this cake tin, the antennas were also slewed into their desired sub-directions.
In some detail10,
(1) the African and European array centered at 7.5 degrees which, with slewing, serves East and North Africa as well as Euirope and the Middle East, (2) the West African array centered at 20 degrees whioch, with slewing, covers West Africa as ffar South as Angola and Wet Europe, (3) the North American array at 55 degrees which, with slewing, covers all of that continentn and, when reversed, serves Australia and New Zealand. A fourth array has also been provide for, which, when put into operation at 105 degrrees, will cover Central and most of South America and when reversed, will serve India and the Far East."
The way I understand the sources‘ description of Bloemendal transitter site
While the Radio RSA studios were always in Johannesburg, through all the Bloemendal operational years from 1966 to 2019, they hadn’t been in Auckland Park from the beginning. The previous address had been Commissioner Street.
"[South Africans] have tried to make our voices herd in a small way in the past and now from today we are joining those other countries of the world, wether great or small, who make their voices heard to the furthest ends of the earth", Orlik quotes then South African prime minister Verwoerd11, during the opening ceremony at Bloemendal transmitter site.
But what did that radio world look like, and how did Radio RSA compare to stations like the BBC World Service, Radio Peking, Radio Cairo, Radio Moscow, or Voice of America in terms of transmitters, number of languages and broadcasting hours per week?
During that better half of a century that Radio RSA and then Channel Africa were broadcasting on shortwave, both South Africa and the world saw a lot of change. But that’s for the next blog on Radio RSA.
