Such an impression is not well grounded. The following description of a small wireless set will not only be useful to those who wish to experiment along this particular line, but it will be a great aid in making clear the elementary principles upon which wireless telegraphy is based. A set suitable for transmitting for distances of four or five miles in the open country can be easily constructed by a boy of ordinary ability at a small cost. The information gained by constructing a small set would be a great help to those who intend building larger outfits later. Before explaining the construction of the various parts in detail, it might be well to give a general description of them and explain their functions and operation. You will need the following parts to complete the equipment for a single station that can both send and receive a message: A spark coil that is capable of producing a spark from 1to 12 in.
