AWA Pennant Hills Transmitting Centre

1930
One of the earliest commercial wireless stations in Australia, AWA Radio Centre, Pennant Hills, near Sydney, at the time was the largest and most modern of its kind in the Southern Hemisphere.

The chief functions of the Centre comprised the

Beam Feeder Transmitters, operating with Melbourne

The Coastal Radio Transmitters, communicating with Rabaul, Fiji and Noumea, and also with Adelaide, Perth, Townsville and Brisbane

Sydney Radio short-wave long-distance transmitters communicating with ships at sea

The ordinary 600 and 800 metre marine transmitters

The NSW Police Transmitter, keeping police headquarters in touch with the Police Patrol Cars

The 5 kW Broadcast Transmitters of Broadcasting Station 2FC

The Trawler Transmitter for communication with trawlers operating on the NSW coast

In addition, AWA Radio Centre, Pennant Hills, housed the shortwave broadcasting transmitters for overseas broadcasting to England, Canada and the United States, for relaying in those countries.

Whilst the whole of the above transmitting functions were carried out by AWA Radio Centre, Pennant Hills, the actual operating of the various units is actuated by "remote control" from various parts of Sydney, and also from La Perouse.

The AWA designed and manufactured 20 kW oil-cooled transmitter used for Empire and world-wide shortwave broadcasting and overseas telephony, is also installed at Radio Centre, Pennant Hills. The whole of the transmitters at this station were designed and manufactured by AWA.
