Abstract
A development of the “echo” method of observation of the height of the Kennelly-Heaviside layer is described. Short wave-trains of radiation lasting sec. are transmitted at regular sec. intervals, and observed stroboscopically, together with their echoes, by means of a cathode ray oscillograph. Details of the transmitting and receiving apparatus are given. The rapid fluctuation in amplitude of the echoes is easily studied by this method.
