Washington.—Ingenious combination of the radio, a dial similar to that of an automatic telephone, and a small call board has been hit upon by an Army Signal Corps officer to facilitate communication from the ground to airplanes by supplementing telegraphy with a visual signal system.
The officer is Captain Paul A. Edwards, commanding the Signal Corps Cook Field, Dayton, Ohio. A report on his experiments has been made public by the war department.
Captain Edwards produced the apparatus by modifying the Radio Beam signal, which by means of Morse telegraph code keeps aviators aware of their course. It makes possible the mechanical sending and receiving of prearranged visual radio signals consisting of numbers.
Use of the numbers would enable a code of 100 different words or messages to be automatically transmitted from ground to plane. With two-way communication established, the system is believed to have considerable value in observing and reporting artillery fire.
