Siphon Recorder


an electromechanical device that records the symbols of the Morse telegraph code in the form of a zig-zag line on a moving paper tape. The recorded message is read from the peaks and valleys traced along the upper parts of the line. Only electrodynamic types are used in modern (1974) radiotelegraphic communications. Modern receivers can handle dispatches at rates of up to 700 words per minute.
