History and use
This is a component of home made equipment used to send the first television signals in Queensland, and possibly Australia. Made of Meccano parts and various other pieces of household equipment, with pinholes in the wheel, this device allowed images to be scanned and transmitted.
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.
