Systematic long-term duct propagation conditions over a VHF overhorizon path between Greece and Italy

A TV, VHF over-the-horizon radio path between Greece (the island of Corfu) and South-East Italy (Martina-Franca) across the channel of Otranto has been studied during 1961-1965. The recorded power levels at Corfu Radio Station indicate permanently ducting propagation phenomena. This is an example of such prolonged conditions observed frequently [3]-[5] in temperate regions and more specifically in the Mediterranean area.
