Radio Pictures

A To be Transmitted from 2FC and 3LO

Y [HE engineering work in connection with the transmission of pictures from Broadcasting Stations 2FC and 3L0O, Melbourne, is now proceeding, and, according ‘to a statement made by Mr. BH. T. Fisk, managing director of Amalgamated. Wireless (Australasia) . Ltd., transmission will commence as — soon as business arrangements are completed. A.W.A. has a limited quantity of radio picture receiving apparatus available for the use of experimenters. The demand which was set up in Britain for Fultograph receivers as soo the British Broadcasting Comfy commenced transmitting pictures, should be repeated in Australia. Any object that is capable of being phot6égraphed can be transmitted and received ‘under the Fultogtaph -system. Ordinary events of the day, sections of newspapers, typewritten documents, and business contracts can all be trans‘mitted. 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. The receiving apparatu , takes the place of a loudspeaker. 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 in turn direct the stylus «pen that prints the photograph of the 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. No price has Yet been fixed for the receiving apparatus in Australia, but it is estimated to be less than £40,
