Mr. Henry ha:used radio receivers in automobiles and small boats for several years, and his remarks on various types obought receiving sets and their use may assist you in choosing a good outfit for yourself. A receiver oyour vacation will be a source of great pleasure if it is kept in working-order, but it will only be an extrpackage to lug around if it"goes bad."The author has just returned from a thousand-mile automobile trip and some of the difficulties encountered are still fresh in his mind.
