ELECTRICIAN FOR THE STATE GOVERNMENT POSTAL AND TELEGRAPH SERVICES.
"The Western Wireless" September 29th 1926.
It was to be another 6 years before the "wireless experimenters" of
Australia were to be regulated by the WIRELESS TELEGRAPHY ACT (1905).
Marconi was still making his epic discoveries in the field of wireless,
yet in October 1899, Stevens carried out a series of experiments in the
new science, the first known experiments to be conducted in Western
Australia.
An interesting document dated October 26th 1899, and headed
"Experiments by the Telegraph Branch of the General Post Office to
ascertain the practicability of establishing communication by that
system between Rottnest Island and the mainland" was presented to both
Houses of Parliament "By His Excellencies Command"
The document reads:
With the cooperation of the Police Department, and assisted by Mr.Knox
of the Telephone Branch, and Messrs Rosser & Phillips , I carried
out a series of experiments on the 11th inst. with a view to testing
the distance to which it was possible to signal without wires with the
apparatus presently at my command, viz: a six-inch spark coil as a
transmitter, and unexhausted coherers, made in our own workshops, as
receivers.
Using a vertical conductor suspended from the flagstaff of the
Royal Yacht Club, at a height of 40ft above water level, and a similar
conductor supported by a temporary mast on (the) police launch, we
commenced signalling across the water at 200 yards: then, putting the
launch under slow steam, the distance was gradually increased,
communication being kept up all the time until, at about three quarters
of a mile, the coherers failed to respond. Careful tests were made, and
all possible variations of spark length tried, but no effective waves
could be detected outside the three quarter mile radius. By means of
flag signals, the launch was instructed to return slowly, and
immediately it entered the magic circle, the electric waves were again
picked up, and steadily increased in volume as the launch approached:
the Morse code being readily read throughout.
. . . The results were not as satisfactory as I had anticipated,
but were quite sufficient to confirm me in my opinion that with proper
appliances, the system would be quite reliable, and meet all the
requirements for conveying shipping intelligence to and from Rottnest.
. . . . it would be unreasonable to suppose that we, with
the very meagre description of the system available through the
scientific papers could, in a month, attain the perfection of detail
that has taken Mr.Marconi, assisted by some of the cleverest
electricians in England, Five years to accomplish.
TO PUT THINGS IN PERSPECTIVE, Marconia had succeeded in sending
Wireless Telegraphy about 20 miles, to successfully span the ENGLISH
CHANNEL in March that year, and nearer home, the CITY OF YORK had sunk
off Rottnest with the loss of 12 lives during a storm.
Communication at the time was by coloured flags to the Port of
FREMANTLE.
Was Stevens trying to demonstrate his faith in the new science of Radio
to the Government? Unfortunately he did not succeed, it wasnt long
before a cable was laid linking the island with the mainland.
