METEOR FACSIMILE VIA METEOR TRAIL PROPAGATION

Abstract

Experimental equipment for the transmission of facsimile by meteoric-scatter propagation was tested for over 5 months on a radio circuit from Long Branch, Illinois to Riverhead, New York. Operation late in 1957 employed start-stop operation, in which the line sweep at the receiving terminal was synchronized by the incoming sync pulses, in the manner of a television receiver. About a year later, equipment was added to provide full synchronous operation, in which the (over) line sweep at each terminal was derived from a local frequency standard. Operation in 1957 was on a carrier frequency of 40.0 mc, and in 1958 on a frequency of 49.72 mc. A comprehensive analysis and evaluation of the test results obtained during 1957 activities are presented along with similar treatment of the results employing synchronous operation in 1958.
