Of course, there are many amateurs who like tomake several types, but it is for those who desire to make butone detector, that this short description is written. Of all the modern wireless detectors—the electrolytic, thecarborundum, magnetic, silicon, audion—the electrolytic is givenfirst place. It is very easily made, and when made well requiresvery little adjustment or attention. The silicon and carborundumdetectors being of the crystal type are fairly sensitive when cor-rectly adjusted, but it is very hard to strike the maximum sensi-tive point. The audion is beyond the reach of most amateurs,because it employs platinum grids sealed in an electric-light bulb HANDY MAN S WO
