Fultograph

A Fultograph image, 65×129mm.

The fultograph was an early, clockwork image-receiving device, similar in function to fax machines. It took signals from the loudspeaker socket of a radio receiver and used an electrochemical process to darken areas of sensitised paper wrapped on a rotating drum. Invented by Otho Fulton, the system was used briefly in the late 1920s to broadcast images to homes by radio. The machines themselves were expensive (£22 15s 0d in 1928) and required a good receiver to operate.^[1]

The BBC broadcast Fultograph images in 759 programmes between 1929 and 1932.^[2] The Fultograph was the subject of an article in the British RadCom amateur radio magazine in October 2007.
