Show Automatic Radio Will Guide Airplanes Washington An ingenious combination combin-ation of the radio, a dial similar to that on an automatic telephone and a small call board, has been hit upon by an army signal corps officer to facilitate facili-tate communication from the ground to airplanes by supplementing telegraphy teleg-raphy with a visual signal system: The officer is Captain Paul S. Edwards, Ed-wards, commanding the signal corps aircraft radio laboratory at McCook field, Dayton, -Ohio, a report on whose experiments was made public by the war department. Captain Edwards has produced the aparatus by modifying the beam signal, whi-.-h, by meana of Morse telegraph code, keeps aviators constantly aware of their course.
