In General.—Unless the student can apply in a practical way the fun-damental knowledge of radio which he has gained in the class-room, he is hardlyqualified to operate commercial wireless telegraph equipment. The ability to lo-cate troubles in radio apparatus as they arise constitutes one of the most im-portant essentials of a first-class operators qualifications. The author would notcreate the impression that the radio telegraphist may expect to encounter aninordinate amount of trouble when he takes charge of a ships wireless station,because modern wireless apparatus if properly c
