Excerpt from Researches in Radio Telephony: A Thesis In the last few years the strides in radio telephony have been very rapid. About ten years ago the scientific world was first introduced to the fact that radio telephony was possible; but for the first few years following, the progress in this branch was comparatively slow due to the difficulties in the generation of high frequency currents of the undamped wave type. The only two ways it was found possible to generate currents of this nature was by the arc generator or by the high frequency generator; but in the last six or seven years a new type of generator has come into existance; namely, "The Hot Cathode Vacuum Tube." This generator practically revolutionized the entire field of radio telephony and to a lesser extent radio telegraphy; but had it not been for the war, it is rather doubtful whether our advance in this science in the last four years would have been quite as rapid as it has been.
