Wireless Telegraph Construction for Amateurs #225649

IN this work, the author has endeavored to present a book embracing practical information for those who may wish to build for private or experimental use a set of wire less instruments which are more than toys but yet not so expensive as the commercial apparatus. Many books have been published on the Subject of wire less telegraphy, but in them the interests of the novice have been rather neglected and in order to build an outfit he has been forced to rely upon a series of disconnected articles published in the amateur periodicals. It is the object of this book to Show the construction of Simple, efficient instruments by means of clear drawings, and to give enough elementary theory and practical hints to enable the experimenter to build a size and type in keeping with his needs and resources.
