Abstract :
Graphic records of radio signals transmitted from high-frequency aircraft radio transmitters are observed to show periodic variations of fairly constant frequency over considerable time intervals. A theory is evolved connecting this frequency with the transmitting distance, the ground speed of the plane and the effective height of the Kennelly-Heaviside Layer. Records of such periodic fading are reproduced from which, in accordance with this theory, the height of the layer is computed. A short discussion is given of the results obtained.
