Wireless Hill celebrates telecom history

Written by  Cris Burne

• Wireless Hill first communicated with ships via Morse code and went on to relay messages from space
• Initial Morse code technology used high voltage sparks to create bandwide signals to transmit messages
• Entertainment radio and even television first came to WA through Wireless Hill

FROM Morse code to space-age satellites, the Applecross Wireless Station—now the Wireless Hill Museum and Park—connected WA to the world for more than 50 years.

“The Wireless Hill story really shows what you can achieve if you invest in science and innovation,” Wireless Hill Museum Curator Gina Capes says.

Opened in 1912, the wireless station first provided weather forecasts and medical information to ships up to 1600km away, and by 1927 was communicating directly with England.

“What’s really exciting are the giant leaps in technology that occurred during this period,” Ms Capes says.

“The first demonstration of wireless communications was in 1888…then by 1912 we had wireless communication for the first time between the east and west coast of Australia,” she says.

“It was the first time in Australia’s history that the nation was united with direct wireless telegraphy, and this was extremely significant for Perth.”

The earliest radio communications at Wireless Hill were achieved using a 25 kilowatt spark-gap transmitter, which used high voltage sparks to create wideband on-off signals that operators used to transmit messages in Morse code…..READ MORE
