Wireless Hill Park
Wireless Hill Park is a 40-hectare (99-acre) park in Ardross, Western Australia that is the location of the former Applecross Wireless Station,[Note 1] an early radio station in Western Australia. The station buildings have been preserved and now house the Wireless Hill Telecommunications Museum. The site is listed in the Register of the National Estate and the State Register of Heritage Places.
The park is also a significant urban bushland area.
In 1909 the Commonwealth Government decided that wireless telegraphy stations should be established around the coastline of Australia, and in 1910 awarded the contract for the Perth station to Australasian Wireless Limited. Clearing of the site and construction began in 1911, with the Applecross Wireless Station completed and officially opened on 30 September 1912.
In 1916 as a consequence of World War I, the Royal Australian Navy took control of the station (and all Australian coastal radio stations), retaining existing staff and giving them naval ranks as non-commissioned officers. The Navy retained control until 1920. The Navy took control of the station again from 1939 to 1945, during World War II, again retaining the existing staff.
Between 1967 and 1968 OTC moved all of its operations from Wireless Hill to its new station in Gnangara, and in 1968 the Wireless Hill station closed. The land was transferred to the City of Melville in 1969, and in 1971 was formally renamed as Wireless Hill Park. (The site was already commonly referred to as Wireless Hill by the local residents.):117
In 1970 the West Australian VHF Group (an amateur radio club) proposed establishing a telecommunications museum. In 1974 work began on converting the station, and in 1979 the Wireless Hill Telecommunications Museum was officially opened as a contribution to Western Australia's sesquicentennial celebrations.
Buildings and structures
- Engine House or Engine Room, built in 1912, originally held the generator used to power the transmitter. In 1942 the generator was removed and the radio equipment was moved into this building, which then became known as the Transmitter Hall.
- Operator's House or Operator's Room, built in 1912, the location of the radio equipment until 1942.
- Stores building, added c1915.
Initially, a 120 m (390 ft) antenna mast was erected, held in place by three guy-wires, each attached to a 4.6 m (15 ft) 200-ton concrete anchor block. In 1930 a light was added to the top of the mast, as was required of all structures exceeding 200 ft (61 m), to warn aircraft at night of the mast's existence. The original mast was replaced in 1962 by a 46 m (151 ft) mast, the taller mast no longer being required by the newer technology. The mast was removed in 1967. Two of the anchor blocks are now used as viewing platforms.
At the bottom of the hill, on Hickey Street near Canning Highway, four cottages were built as staff accommodation. The road between the cottages and the main station buildings was known as Radio Drive, and was possibly the first macadamised road in Perth.
When the station opened in 1912 it used a 25 kW quenched spark-gap transmitter manufactured by Telefunken, and a receiver with a locally built crystal detector (using galena from Northampton). In 1916 the transmitter was upgraded (by the Navy) to a 60 kW Poulsen arc transmitter and vacuum tube receiver.
Initially all radio transmissions used Morse code; the technology to transmit voice was developed in the 1920s, and even then Morse code was still the primary method for long distances up until the station closed in 1968.
Numerous antennae were added to the site over the years, each for a particular purpose, particularly after OTC took control of the station. In 1960 two rhombic antennae were installed for use with NASA space missions, bringing the total number of antennae up to 22.
The Wireless Hill station provided a variety of radio services during its operational lifetime.
Initially the station was used for communications with shipping. This included transmission of weather forecasts, news bulletins and time signals, sending medical advice to ships with no doctors aboard, and monitoring for distress calls. In 1921 the station exchanged signals with SS Aeneas over a distance 9,000 kilometres (5,600 mi), the longest distance for any Australian station at the time.
Police radio (VK-1) was transmitted from Wireless Hill, operated remotely from police headquarters in Roe St, Perth. Initially, in the late 1920s, two patrols cars in Perth were equipped with radios.
Western Australia's first commercial radio station, 6PR, was broadcast from Wireless Hill between 1931 and 1950, relayed from a studio in Barrack Street. Western Australia's first television service (TVW7) was broadcast in 1959.
A shortwave antenna was installed in the 1970s, and is still in use by the WA VHF Group.
Wireless Hill Park comprises 38 hectares (94 acres) of bushland surrounding 2 hectares (5 acres) of grass parkland. The bushland is home to numerous wildflowers, native plants, birds and reptiles. It is listed as site 336 on "Bush Forever", a state government policy to protect regionally significant bushland.
Much of the area was cleared when the Applecross Wireless Station was originally built or shortly afterwards during World War I for security reasons. Perennial veldtgrass was planted to prevent soil erosion, but the bush has regenerated itself from seeds from plants in surrounding areas.
The park has several walk trails through it.
Prior to European settlement Wireless Hill was part of the land occupied by the Beeliar people. It was once known as Yagan's Lookout, after the Aboriginal leader who used the area as a home base and vantage point.
- When the station was constructed, the site was in the suburb of Applecross. Due to subsequent changes to the suburbs' boundaries, the site is now in Ardross.
- The Wireless Telegraphy Act 1905 gave the Commonwealth Government the exclusive right to establish and operate radio stations.
