The Feldfernschreiber telegraph device

The Feldfernschreiber is a military, field version of the Hellschreiber, the teleprinter patented by Rudolf Hell in 1929. The purpose of the device is to transmit text messages over a wire or radio connection. Unlike earlier teleprinters, the Feldfernschreiber transmitted complete information about the appearance of the character and not its symbolic, codified representation. This made the transmission resistant to interference, as a distorted character generally still remained legible. This feature also allowed the device to be easily adapted to work with different alphabets and writing systems. During World War II, devices based on Hell's system were used by field units of the German army. After the war they were widely used by mail and press agencies. Much like standard teleprinters, the devices remained in use even until the 1990s.
