History and use
This is a component of home made equipment used to send the first television signals in Queensland, and possibly Australia. This piece was the actual transmitter, and contained the power supply.

X-ray technician Thomas Elliott spent years experimenting with the radio in Queensland, working from the old observatory on Wickham Terrace with radiologist Val McDowell, owner of experimental radio station 4CM. Over a period of months, Elliott built this television transmitter.

The first transmission was made on 10 April 1934 from the observatory to Alan Campbell's home at Wilston Heights, where his 11cm screen received the first image, which was of actress Janet Gaynor. The first news transmission - a section of a local newspaper - took place on 9 October 1935. The experimenters were soon able to provide animation in the form of old advertising films of Mickey Mouse playing the piano produced with a portable 35mm sound projector built by Campbell. This is said to have been the first such televised animation in Australia.
