STATION

Back in the days before World
War 2, there were two ships in Australasian waters that were
quite famous in the international radio scene. One was the "Awatea"
that plied across the Tasman Sea between Australia and New Zealand,
and we will tell you the story of that ship radio station on another
occasion.
The other ship radio station was aboard the MV "Kanimbla"
that plied in Australian waters. Both ships were built in the
United Kingdom, both were launched in the year 1936, and both
were noted for the broadcast of radio programming; the "Kanimbla"
as VK9MI and the "Awatea" as ZMBJ.
The notable fact about the passenger liner "Kanimbla"
is that it was the only ship in the entire history of our world
in which a radio broadcasting station was constructed into the
ship at the time when the ship was built.
The 11,000 ton passenger liner "Kanimbla" was built
at Belfast in Northern Ireland, by the famous ship building company,
Harland and Wolff. The electronic equipment was manufactured by
AWA in Australia and shipped to Ireland for installation while
the ship was still under construction.
The "Kanimbla" was granted by the PMG Department in
Australia a radio broadcasting license with the experimental callsign
VK9MI and, as we mentioned earlier, it is the only ship in the
world to have a radio broadcasting station incorporated into it
at the time of construction.
The radio station consisted of two studios; one for group broadcasts,
and the other for announcer presentation. The crystal controlled
transmitter was rated at 1.5 kW, though the QSL card states that
the output into the antenna system was just 50 Watts. This would
seem to suggest that the original broadcast transmitter malfunctioned
quite early and that the broadcast programs were then radiated
from the ship's communication transmitter.
The original AWA transmitter could operate on any wavelength between
20 and 50 meters. The first test broadcast from 9MI was made on
April 21, 1936 during sea trials in the Firth of Clyde.
The new MV "Kanimbla" began its delivery voyage from
Northern Ireland to Australia at 4:00 am on April 26, 1936. It
is reported that the radio station 9MI made four test broadcasts
each day during this 25,000 km journey to Australia.
The official inauguration of the new radio broadcasting station
VK9MI was made in a special broadcast to Australia while the ship
was south of the continent in the Great Australian Bight, 1500
km from Sydney. At 8:00 pm Eastern Australian Standard Time, VK9MI
went on the air shortwave and the program was picked up and relayed
thoughout Australia over the ABC mediumwave network.
This inaugural broadcast from 9MI was made on 11720 kHz, though
subsequently the regular channel was 6005 kHz, though this was
modified in April 1939 to 6055 kHz. The at times irregular schedule
from VK9MI was usually half an hour or an hour a few evenings
a week. The announcer and manager was Eileen Foley, who also signed
the QSL cards.
The "Kanimbla" plied with passenger traffic backwards
and forwards on the southern route between Western Australia and
Queensland, and the ports of call in this shuttle service were:-
Fremantle in Western Australia
Adelaide in South Australia
Melbourne in Victoria
Sydney in New South Wales; and
Brisbane and Mackay in Queensland.
The local AWA mediumwave stations on land in each of these areas
frequently relayed the shortwave programming from VK9MI to the
local audience. Among these stations were 2AY in Albury New South
Wales, 3BO in Bendigo Victoria, and 4CA in Cairns Queensland.
On many occasions, radio station VK9MI was heard on shortwave
throughout Australia and New Zealand, and many QSL cards were
signed by the famous woman announcer, Eileen Foley. As time went
by, the transmitter began to malfunction and it produced a noisy
wide signal in the 49 meter band.
At the outbreak of the European War at the beginning of September
1939, the radio station VK9MI was silenced, along with all other
experimental shortwave stations in Australia. The "Kanimbla"
then became a troop carrier, and after the war, it was unceremoniously
scrapped.
The unique ship broadcasting station VK9MI was on the air therefore
for a period of just three and a half years. All that is left
of this radio station these days is found in radio memorabilia,
such as entries in old radio magazines, and articles and books
on the history of radio broadcasting, and a few isolated QSL cards
in old QSL collections.
During the entire period of on-air activity, only one QSL card
was printed to verify reception reports. The Pacific Heritage
Collection in Dunedin holds a few copies of this exotic QSL card,
the CPRV collection in Maryland in the United States holds at
least one copy, and there is just one copy of this valuable QSL
card in the AWR collection in Indianapolis. Our card was signed
personally by the veteran woman announcer, Eileen Foley.
