RADIO PICTURES

TRANSMISSION BY AUSTRALIAN STATIONS START IN THREE MONTHS Transmission of photographs by radio from the Sydney Broadcasting Station, 2FC, is expected to commence within three months, and will be followed by the Melbourne station, 3LO. Engineers at both stations are now ready to commence operations, and the managing director of Amalgamated Wireless (Australasia), Ltd., Mr. Fisk, states that transmission will be started as soon as business arrangements are complete. Any object that is capable of being photographed can be transmitted and received under the Fultograph system that has been installed. Ordinary events of the day, sections of newspapers, typewritten documents and business contracts can all be transmitted. Should the police desire to transmit a photograph or the fingerprints of a "wanted” person it can be put on the air and transmitted throughout Australia within five or ten minutes. No dark-room or developing apparatus is required at the receiving end. The photograph, as printed by the receiving apparatus, is a permanent photograph. At the studio there is attached to the transmitting apparatus the developed negative of a photograph. A powerful beam of light is focussed upon the photographic plate, * the amount of light being regulated by the varying density of the negative. A photo-electric cell controls the signals transmitted. These iu turn direct the stylus pen that prints the photograph on the re-receiver. The synchronisation of the transmitter and receiver is arranged by a number of clutches on the receiver, which are operated by synchronising signals from the transmitter. , . The market price for receiving apparatus has not been fixed for Australia, but it is stated it will cost under £4O. Receiving apparatus is also available for a limited number oi experimenters. The stocking of receiving apparatus will largely depenfl |on the demand. In Britain, after a I few months experimenting with the transmission of pictures by the Fuuo* graph system, which is being adopted i in Australia, it was found that a j number of listeners desired to partic - ij pate.
