Radio Comes to Australia
Arrangements
were made for the “Riverina” to carry the new little “Q” transmitter during its
regularly scheduled voyages for a three-week series of seaborne test
transmissions. These test broadcasts
took place during the month of April, 1919.
The output power was around 10 watts, and the operating frequencies were
in what are now designated as the longwave and medium wave bands. These experimental broadcasts were successful,
although of course, there were very few receivers capable of tuning in to the
informal programming.
At the same time, there was another single-stack steamer plying the Australian coastline – the fifteen-year-old “Bombala” owned by Howard Smith, also of Melbourne. A second series of test transmissions using the same “Q” transmitter was carried out in July of 1919. Clear signals were heard over the salt water pathway at a remarkable distance, even as far away as Gabo Island, more than 300 miles south of Sydney.
Having proven the concept, the next event needed was a genuine public demonstration, and that was soon in the making. Ernest Fisk announced that he would address the Royal Society of New South Wales on Wednesday evening August 13 (1919) and that he would present a live radio program as a practical demonstration of the new radio medium. This event, as a historic first in Australia, was staged in the Royal Society’s Hall at 7 Elizabeth Street in Sydney. A series of some twenty locally-constructed loud speakers with tin horns were all connected to the same receiver and strung from the ceiling. The “Q” transmitter was installed at AWA Wireless House (at 97 Clarence Street in those days) and the sixty foot long “T” type antenna was strung on the roof of the same building. The programming for this first auspicious occasion consisted entirely of gramophone recordings played into a carbon microphone. At the appropriate timing during the Fisk speech, the National Anthem came through suddenly and dramatically; a clear demonstration that radio without wires was indeed a reality. The transmitted signal had traveled in the heart of old Sydneytown from one main street to another covering a distance of about half a mile.
Meanwhile, down in Melbourne, AWA was planning another series of dramatic radio events. It should be remembered at this era, that Sydney was the larger city, but Melbourne was assuming political importance as the de facto capital of Australia due to the fact that the Federal Parliament was headquartered in this city. (The Australian Capital Territory, ACT, and the city of Canberra had not yet been surveyed.) Two Marconi speech transmitters were imported from England and one was installed in the Brighton home of the local AWA manager, Lionel Hooke, with a simple antenna in the family garden. This unit came on air with a special broadcast to the Federal Parliament which was meeting in Queen’s Hall, Melbourne. The date was Wednesday October 13, 1920; the receiving aerial was installed on the roof of Parliament House; and the loud speakers were the ones with tin horns from Sydney.
AWA conducted many promotional test broadcasts in the Melbourne area during this period. The 500 watt transmitter was transferred from Hooke’s residence to another suburban residence, that of engineer Sydney Newman in Canterbury. At this location, the familiar callsign 3ME was introduced. In fact, AWA in Melbourne registered a series of callsigns ranging from 3MA – 3ME. Station 3ME was installed at the permanent fixed location of Canterbury, but the others were apparently used at various temporary locations for demonstration test broadcasts using another 500 watt Marconi transmitter. These two transmitters, twins from Chelmsford in England, were rated at less than one “horsepower”!
At this stage, the AWA callsigns in Melbourne became quite prominent, in fact more prominent than the similar series in Sydney, 2MA – 2ME. In particular, the Melbourne callsign 3ME was soon afterwards transferred to Braybrook where it identified a shortwave transmitter co-sited with 3LO. It was not until AWA began a series of international shortwave broadcasts from Pennant Hills near Sydney that the 2ME callsign became better known than the southern sister 3ME.
This new radio broadcasting station was officially opened on November 23, 1923, with a new 500 watt transmitter operating at lower power under its official callsign, 2SB. This call was changed early in 1924 to the more familiar 2BL. Similar officially licensed radio broadcasting stations were soon afterwards inaugurated in each of the other state capitals throughout Australia.
Back to you, Jeff.

1500 Meters Longwave Part 2 – After World War II
In September 1967, the BBC restructured its
services, and the Light Programme on 1500 metres became BBC Radio 2, which
really was just a change in name only.
And so it continued on 200 kilohertz, 1,500 metres, until November 23,
1978 when a new frequency plan for Europe (the ‘Geneva Plan’) came into
effect. At that time, the former ‘Home
Service, now BBC Radio 4, took over the longwave frequency, and Radio 2 moved
to medium wave instead.
As previously, the Droitwich longwave transmitter continued to give good national coverage for Radio 4, except it was found that in Scotland there were some significant coverage gaps due to the topology, and the fact that Radio 2 had previously had some medium wave transmitters for fill-in purposes. If you’re not familiar with Scottish geography, there are basically three main areas – the Highlands in the north, the Southern Uplands, and a central valley between the two which runs from Glasgow in the west to Edinburgh in the east. And it’s in the central valley where most of the population lives. Because the Radio 4 longwave signal from Droitwich was effectively being blocked by the Southern Uplands, it was decided to add a second longwave transmitter at a place called Westerglen, midway between Glasgow and Edinburgh, and a third on the northeast coast at Burghead for coverage of the Highlands. Both of these operated on the same 200 kHz frequency with a power of 50 kW each, and went into service in 1982.
In 1985, two new 250 kW longwave transmitters manufactured by the Marconi Company were installed at Droitwich, and these were used in parallel to generate 500 kW output power. And these are the same transmitters that are still in use today. On February 1, 1988, the operating frequency was adjusted from 200 kHz to 198 kHz (1515 metres) – the last remaining requirement of the Geneva Plan.
In 2011, as a result of budget cuts, the BBC announced that there would be no re-investment in longwave transmissions. The same year, The Guardian newspaper reported that the Droitwich longwave transmitters each rely upon a pair of glass valves (or tubes) for their final power amplification stage, of which at that stage they reported there were less than 10 left in the world. The BBC stated it was unsafe to manufacture more, because "slightly faulty" replacements could cause catastrophic failure. And so, it was finally announced that BBC Radio 4 will end its longwave broadcasts from Droitwich, Westerglen and Burghead on September 26 this year, 2026, and then remaining on FM and digital only. 1515 meters, 198 kHz will then be silent forever.
Back to you, Jeff.
