Correction

H.H. Davids, of the General Electric Company, Electronics Park, Syracuse, NY, USA has brought the following errors to the attention of the editors. On page 413 of the article entitled, "Radio Progress during 1951," which appeared in the April 1952, issue, there is a reference (389), T.S. Eader, "Equipment performance specs," FM-TV, vol. 11, pp. 22-24, 38-39; September, 1951. The author of this article should be H.H. Davids. Similarly, in the section, "Abstracts and References," the author of the item (745), "A New Method of Predicting the Adjacent Channel Performance of Mobile Radio Equipment by Graphical Analysis," is also H.H. Davids, not T.S. Eader.
