Abstract : This report documents the progress of an investigation of the environmental ionosphere and the characteristics of individual modes of propagation related to it. The path used for the experiment lies between the RADC experimental sites located at Stockbridge, NY and the Panama Canal Zone. Data taken covers World Day periods from May to September 1965. Also included are special operations in October 1965. The modes under study include the one-hop F2, two-hop E, two-hop E sub S, two-hop F2, the guided FF mode and the MM and several three-hop mixed modes. Measurement equipment used includes a Granger oblique transmitter-receiver sounding system at both ends of the path, a high resolution pulse compression transmitter at Panama and an associated receiver at Stockbridge. High gain vertical and horizontal antenna systems are used at both sites. Vertical soundings are provided from Ithaca, NY, Ottawa, Washington, DC and several points on the southern and midpoints of the path. (Author)
