Seventy-five years ago this month, most of the November 1942 issue of Radio News was devoted to the U.S. Army Signal Corps, and included dozens of photographs, including the color photos shown here. The photos themselves were taken by Signal Corps photographers, which comprised a branch of the service.

Here are a few of them, showing various phases of both wireline and radio communications.
