American Radio Stations in New Zealand
Just three weeks ago here in Wavescan, we presented the story of a mediumwave station in New Zealand (1ZM in Auckland with 1 kW on 1250 kHz) that was on loan in 1944 to United States personnel for the broadcast of their own American-style programming. Before station 1ZM became available, American programming was carried by both government radio networks in New Zealand via stations with callsigns in the YA and ZB series. Among the programs noted by local listeners were news, sports and musical programs, including the American Command Performance, and the local New Zealand version of the same program under the name Kiwi Command Performance.

Australian Shortwave Callsign VLS
Princess Hinemoa lived near the water front of Lake Rotorua a large inland lake, and Prince Tutanekai lived on Mokaia Island in the center of the lake. The hidden romance, forbidden by local custom, became well known, and the canoes at the water front were protected, so that Hinemoa could not paddle out to the island.
However one night, Princess Hinemoa clad herself with dry, empty Calabash Gourds, and she swam out to the island, guided in the darkness by the music that Tutanekai was playing on his own home made flute. She arrived at the island, met her handsome prince; and like all good European legends, this Maori couple in New Zealand lived happily ever after.
Named in honor of this princess, the small New Zealand coastal vessel, Hinemoa, just 542 tons and only 207 feet long, was built in the Scott shipyards in Greenock Scotland in 1875. At the beginning of World War 1 (1914), the Hinemoa was listed with wireless apparatus operating under the New Zealand callsign (as it was at the time) VLS. Due to new international radio regulations, all radio callsigns in New Zealand beginning with VL were changed to ZL on January 1, 1929, and thus the little ship NZGSS Hinemoa dropped the callsign VLS and received a new callsign.
The Australian usage of the shortwave callsign VLS was taken up by the AWA shortwave station in Pennant Hills, near Sydney and it was in use during the 1920s and 1930s for the Trawler Communication Service in both voice and Morse Code for the ships that plied along eastern coastal waters. In addition, the long distance communication service from Pennant Hills was registered under the callsign VIS, though sometimes this was erroneously identified as VLS, due to the similarity in callsigns.
During the year 1933, Donald Mackay, leader for the Mackey Aerial Survey Expedition in Central Australia, took mobile wireless equipment for use on the ground and in the air. It is understood that the callsign that he used while at Docker Creek on the border between Northern and Western Australia, was VLS.
Interestingly a total of five different shortwave locations, in use by the ABC Home Service in Australia and the international service of Radio Australia, have all operated under the callsign VLS. We look at each of these occasions in chronological order.
Soon after the end of World War II, the ABC in Australia began assessing their radio coverage throughout the continent and they observed that mediumwave coverage in the heavily populated coastal areas north and south of Sydney was insufficient. It was determined that it would be more economical to provide a radio service to these areas on shortwave from one single location, rather than to install a network of several medium powered mediumwave stations.
The chosen location for this new shortwave station was on the western and southern edge of Sydney, just beyond suburban Liverpool. This was already the location for all of the mediumwave transmitters that carry the two program services, ABC National and ABC Local, for coverage of Australia’s largest city.
Interestingly, during the planning for the new 2 kW shortwave transmitter, the evidence suggests that the suggested callsign would be VLS, with the S obviously standing for Sydney. However, when the transmitter was installed and taken into regular service in December 1948, an even more logical callsign was granted; VLI with the LI indicating Liverpool.
Twenty years later (1960s and 1970s), another well established ABC/Radio Australia shortwave station was already on the air at Lyndhurst in Victoria with programming beamed to the Great Outback, the Pacific and South East Asia. During each summer season, one of the 10 kW transmitters at Lyndhurst was placed into service for the broadcast of live commentaries on the ever popular sport, cricket.
The Lyndhurst transmitter that beamed the cricket commentaries to New Zealand and the Pacific was given the unannounced callsign VLS. Then for example during the next decade in December 1980, a 10 kW transmitter at the larger shortwave station at Shepparton also in Victoria, took over the VLS cricket broadcast for New Zealand and the Pacific.
A new and temporary shortwave facility was installed for Radio Australia at Brandon near Townsville in Queensland in 1989. The original intent was ultimately for a much larger station, and initially only three transmitters at 10 kW each we installed. However, only two antenna systems were erected, and thus only two transmitters could be activated at any one time.
The third transmitter, which was originally intended to carry its own separate programming, thus operated instead as a fill in for the other two. That third transmitter was originally allocated the callsign VLS.
During the 1990s, one of the 250 kW transmitters at the Darwin relay station of Radio Australia was allocated the line callsign S, as in VLS, as a program service to Asia and beyond. Back at that time, Radio Australia was issuing QSLs in the form of a Form Letter, and the verification text gave the callsign as VLS.
And for the final application of the Australian shortwave callsign VLS, we mention the shortwave Aeradio station that carries aviation communications with passenger aircraft in the vicinity of the Kingsford Smith Airport at Mascot, Sydney. Several shortwave transmitters have been in use at this location during the past half century and more, and they are rated at 3 kW, 5 kW and 10 kW. QSL cards from Sydney Aeradio and also Sydney Volmet, identify this station under the callsign VLS.

The Radio Scene on a Volcanic Island in the South Pacific: The recent tragecdy on New Zealand's White Island
People around the world have been saddened by the news of several tragic deaths as a result of a sudden volcanic eruption on White Island off the coast of New Zealand. The White Island volcano erupted suddenly and unexpectedly at 2:11 pm on Monday December 9 (2019), at a time when 47 tourists were making a tour of the island.
The uninhabited White Island is located in the wide Bay of Plenty, some 30 miles off the north east coast of the North Island of New Zealand. It is a submarine volcano, rising a mile off the seafloor, the top 1,000 feet of which is above sea level.
The island is roughly circular in shape with a total area of almost one square mile. In the Maori language of New Zealand, White Island is known as Te Puia o Wakakaari), which can be translated into English as the Dramatic Volcano.
White Island was discovered by Captain James Cook aboard his good ship HMS Endeavour on October 1, 1769. He named the island White due to the intensive cloud of white steam emanating from the island, though he did not specifically state that the island was actually an active volcano.
The island has never had a permanent population, and there is little vegetation on the island. Even the scrubby vegetation is diminishing due to the effects of volcanic activity. A population of Australasian Gannets was numbered five years ago at around 5,300 pairs, though this number has subsequently diminished due to the harsh life for the birds on this island.
In 1867, ownership of the island was granted to Retireti and his sister Katherine Simpkins who were the adult children of a Danish sailor and a high ranking Maori woman. Ownership was passed on to the French born Judge John Wilson a few years later, and he began the commercial mining of the sulfur deposits in the mid 1880s. This first era of sulfur mining on White Island ended in 1901.
A second era of sulfur mining on White Island began in 1913, but ended a year later when the collapse of the crater wall resulted in the death of ten miners. Their bodies were never found. The only survivor was a cat which was given the nickname Peter the Great.
There was a third era of sulfur mining on White Island and this began in 1923. Workers were housed in temporary huts that were erected near the Gannet colony and they commuted daily by small boat, or if the sea was rough, by walking a narrow and rubbly pathway. Heavy machinery aided the mining of the sulfur, but again the project was dropped ten years later due to the poor quality of mineral content.
In 1932, the island was bought by Auckland stockbroker George Buttle, and it has remained in the Buttle family ever since. In 1953 the New Zealand government offered to buy the island, but the owners declined to accept, and instead the island has been declared a privately owned Scenic Reserve. Tourism to this volcanic island is the only form of income, and each year some fifteen thousand or more tourists from all over the world come to see an active volcano close up, or to study its irregular history of volcanism, or to ponder over its nostalgic pioneer backgrounds.
At the time of its most recent dramatic and tragic eruption, 2:11 pm on Monday December 9 (2019), a total of 47 tourists and tour guide officials were at White Island. Another small group were on board a tour boat near the island jetty. They quickly went back to the island and rescued those who were already standing on the jetty and waiting.
Those who were nearby on the island were also rescued. However, those who were further inland on the island perished in the cataclysm, and the helicopter that was on the ground was damaged beyond use. An initial casualty list showed that 12 people survived unhurt, 30 were injured with superficial to serious burns, and 5 were confirmed as dead or missing. These people were from New Zealand, Australia, United States, Germany, China, England and Malaysia.
The volcanic upheaval sent a plume of ash and smoke more than two miles into the sky, a sight that is visible from space. Scientific personnel stated that the event created a local radio blackout that extended for four hours.
In spite of the paucity of human activity on the island, a small though important communication radio station was in use thereon. During the third mining era running from 1923 to 1932, this radio communication station was registered with two very different though official consecutive callsigns.
In 1928, the allotted callsign was VMDJ, and strangely it was granted an operating frequency within the 80 metre amateur band. A four letter callsign beginning with the two letters VM is reminiscent more of a station located on a South Pacific island rather than an official New Zealand location.
The subsequent callsign, shown in a 1933 list, was given as as ZLI. A three letter callsign beginning with the two letters ZL indicated a communication station in New Zealand, and generally a station of significance.
In more recent years, a whole series of small automatic transmitters were installed at various locations around the volcano on White Island. These small transmitters can be best described as being similar to the small automatic transmitters that are used to convey weather related information to a central location. The small units located on White Island convey various aspects of information related to volcanic changes such as land movement, gases emitted, and temperature changes.

Vanuatu Capital Development Work Begins
With the support of the Government of Vanuatu, the Vanuatu Broadcasting & Television
Corporation (VBTC) has begun work this month on a 942 million vatu (US$8.1m)
infrastructure upgrade to improve radio and free-to-air television service throughout
Vanuatu.
The first phase involves the design, installation and commissioning of a new shortwave (HF)
and medium wave (MF) service for Radio Vanuatu, the country’s public radio service. Costing
for phase one will be in excess of 242 million vatu (US$2.2m) and is funded by the
Government of Vanuatu. Following the improvements to shortwave and medium wave
services, VBTC will also undertake technical work to strengthen the coverage and reliability
of its FM services.
A 10kw MF Nautel transmitter imported out of Canada and a 10kw HF transmitter
manufactured by Hanjin Electronics of South Korea will be installed at VBTC’s major public
service transmission site at Emten Lagoon on Efate. Both transmitters will be commissioned
before the end of 2019.
The second phase, beginning early 2020, will reopen Radio Vanuatu’s medium wave radio
transmission facilities at St Michelle in Luganville on the island of Santo. This will provide AM
service to provinces in the top half of Vanuatu at a cost in excess of 300 million vatu
(US$2.5m).
The third phase will expand the national television free-to-air service, Television Blong
Vanuatu, along with a new digital television service. This final phase will cost an estimated
400 million vatu (US$3.5m).
Prime Minister Charlot Salwai Tabimasmas launched the capital development upgrade at a
special function attended by cabinet ministers, senior members of the public service,
members of the diplomatic corps and members of Vanuatu’s business and non-profit
communities on Friday September 20 in Port Vila before he departed the country to attend
the UN General Assembly in New York.
In his address, the Prime Minister spoke at length about the importance to Vanuatu of having
a strong national public radio and television broadcasting service and announced assistance
from Vanuatu’s development partners to help achieve this objective.
The Government of Australia funded the scoping study for the radio upgrade project and is
providing funding support to implement the strategic reform programme of VBTC which the
Prime Minister said is making good progress.
“I’m also happy to announce that the New Zealand Government is keen to support the
second stage of the Radio Vanuatu technical infrastructure upgrade while China is
considering my request to support the upgrade of Television Blong Vanuatu’s technical
infrastructure.”
Meanwhile Kordia New Zealand Limited has been awarded the contract to project manage,
design, install and commission the new radio transmission facilities beginning with the
facilities at Emten Lagoon outside Port Vila.
VBTC Chief Executive Officer, Francis Herman said that “Kordia has extensive experience in
the broadcasting and telecommunications industry in the Pacific, and recently completed a
major project in Samoa for State-owned Radio 2AP funded by the Australian Government”.
“We’ve worked hard with Kordia and a number of other technical experts to investigate the
most efficient and sustainable transmission solution for Vanuatu taking into account the
inclement weather, and the need to keep operating costs affordable.”
The shortwave service, which will be commissioned before the end of this year, will provide
national radio coverage to the 82 islands spread spanning 1,300 kilometres between the
most northern and southern islands.
“Our role as Vanuatu’s national broadcasting service is centered on helping create an
informed public opinion so our people can contribute more effectively to national
development”, Herman added.
“VBTC has struggled to remain relevant over the past decade because its technical
infrastructure was obsolete and badly neglected making it challenging for us to provide an
efficient, reliable, and responsive national radio and television service.”
Alongside the infrastructure upgrade, is an extensive programme to strengthen the technical
capacity of Vanuatu’s broadcast technicians along with a long-term maintenance regime to
expand the life of the equipment.

Australian Shortwave Callsign VLR
Throughout the entire one and a quarter centuries of wireless and radio history, there have ever been only two stations that have been allotted the callsign VLR. The first application of the call VLR was for the communication transmitter aboard a small passenger/cargo ship in the waters off New Zealand, and the second application of the callsign VLR was for the the internationally well known low power shortwave service operated by the ABC and Radio Australia at Lyndhurst in Victoria.
The SS Marama was built at Greenock in Scotland and it was launched in 1907. During its 30 years of international ocean going service, it was in use for the TransTasman route between New Zealand and Australia, and in the TransPacific service between New Zealand and North America.
The normal peacetime service of the SS Marama was interrupted for a period of four years during World War 1 while it was in use as New Zealand’s second Hospital Ship for soldiers wounded on service in Europe. On one occasion, the Marama was accosted by a German submarine in the North Atlantic, but as a hospital ship it was permitted to move on unmolested.
The Marama was laid up at Evans Bay, Wellington in 1936, and next year it was sold to China, and then sold again, this time to Japan at a nice profit. It was broken up at Osaka in Japan during the year 1938.
During the early 1920s, the callsign aboard the Marama was VLR, and this callsign was modified to ZLR on January 1, 1929 due to new international radio regulations. During the 1930s, there were times when a daily newspaper was published aboard the Marama with news taken from various radio sources. This daily newspaper was given the appropriate though rather unimaginative title, Daily News.
The original VLR shortwave station in Australia was born in a galvanized iron shed on top of a low rise near Lyndhurst some 25 miles southeast of Melbourne in Victoria, in 1928. Back then, this locally made 600 watt transmitter was operated experimentally without callsign on 5800 kHz. However, due to the fact that the audio source for this little new shortwave transmitter was taken from the two mediumwave stations in Melbourne, 3LO & 3AR, then the shortwave unit was soon afterwards given a sort of combined call 3LR.
Due to a change in international radio regulations, amateur stations in Australia were required to add the prefix VK to their callsigns, by December 31, 1928. In order to ensure the change of callsign throughout Australia by the effective date, the Chief Radio Inspector Mr Jim Malone authorized the usage of the new VK prefix from December 8 onwards. That was for all amateur radio stations.
However, mediumwave broadcasting stations in Australia never did use a prefix, just a single digit number identifying the state, followed by two letters identifying an individual station. But, the radio relay station at Lyndhurst was an anomaly, it was neither an amateur station nor a mediumwave broadcasting station. According to the QSL cards that were issued during that era, the accepted callsign for Lyndhurst shortwave was simply 3LR. In this way, it was treated as a broadcasting station.
During the year 1934, a new building was constructed adjacent to the old original shack at Lyndhurst, and on March 12, shortwave 3LR began a regular relay of programming for the benefit of people living in Australia’s isolated outback areas. At this stage, the transmitter was still operating at just 600 watts and the usual channel was 9580 kHz. The regular broadcast antenna was a horizontal half wave doublet at 95½ degrees from true north, with a radiation lobe towards the great outback.
Back during this era, the Lyndhurst transmitter with its programming relay from 3LO and 3AR was identified officially and unofficially as both 3LR and VK3LR. In experimental usage though, the allotted callsign was VK3XX, with the X following the American pattern identifying an experimental station. In May 1935, the 600 watt transmitter was engineered to operate then at 1 kW.
Around June 1936, transmitter (VK)3LR began to carry an experimental 10 minute bulletin of news twice weekly in French for the benefit of French islands in the South Pacific. This genuine overseas foreign language service, though quite short in duration, was a forerunner to the inauguration of Australia Calling/Radio Australia three years later. The French Consul-General in Sydney made request for the continuity of this French language service.
In 1937, the Lyndhurst transmitter was completely reconditioned and the power rating was increased to 2 kW, though still with the same original transmitter. Soon afterwards, the power level was again increased, this time to 5 kW.
At this stage, the lonely little shortwave transmitter at Lyndhurst now radiated through two antenna systems as needed; for national coverage through the same horizontal doublet, and for international coverage, a rhombic beamed on Daventry in England. December 1 (1937) was the official date for the regularization of the callsign from (VK)3LR to the now more familiar VLR.
More about VLR next time.
