The dust jacket for this book states it's "A streamlined home-study course in basic radio" and "requires no previous experience in mathematics or physics". It's by Abraham Marcus and William Marcus. Prepared under the direction of Ralph E. Horton. Fourth printing April 1943.

The dust jacket is present but has quite a bit of wear. I did not observe any writing on the pages. Some discoloring from age. The back cover has a crease in it from top to bottom in the middle.
