Abstract
ALL those concerned with radio research and development will welcJiife he reappearance, after a four-yeansuttprval, of the R.C.A. Review, a technical journal recording progress in radio and electronics as described by scientific workers, engyxeers and executives of the Radio Corporation of America. The March 1946 issue forms the first number of volume 7; and in an introduction thereto General David Sarnoff, president of the Radio Corporation of America, explains that the new R.C.A. Review is written by men of science and engineers not only to relate their past achievements but also to reflect the thoughts of those whose pioneering in research, development and engineering are projecting the present into the future. The eight papers in the present issue cover a variety of subjects relating to television, navigation and radio telegraphic signalling by change of frequency in contrast with on-off keying. The experimental results obtained in the development of omni-directional radio beacons for aerial navigation are described in a paper by D. G. C. Luck, of which the first two parts were published in 1941 and 1942. Another paper, by I. F. Byrnes, discusses the possibilities of a shipboard radar installation as an aid to navigation for the mercantile marine. The development of the image orthicon tube for an extremely sensitive television camera is described by R. D. Kell and G. C. Szikali of the Research Dept., R.C.A. Laboratories; while some of the results obtainable by the use of this camera for field television operation are dealt with by R. E. Shelby and H. P. Lee, of the National Broadcasting Company, Inc. Short biographical notes with photographs of all the contributors form an ia flfesting appendix to this publication.
