HF Radio Wave Absorption in the Nighttime : Part II. Measurements of the Field Intensity of HF Radio Waves by Means of Narrow Band Receivers (Reports of the Japanese Antarctic Research Expedition)

Narrow-band receivers developed for receiving exclusively the JJY signal in the presence of interferences by the other standard frequency waves with an identical carrier frequency are used since 1967 for the observation of HF radio wave absorption on board the ship of the Japanese Antarctic Research...
