Amateur Transmitters

Growth in U.S.A. IN his statement before the U.S. Senate Committee on Inter-State Commerce last month, Mr. Hiram Percy Maxim, the president of the American Radio Relay League, outlined the history of amateur work in the United States from the early days when a few experimenters engaged in two-way radio communication with each other, unfettered by regulations, to the present time when 17,000 or more transmitters are restricted to the use of a few narrow wavebands. It is interesting to note that the Radio Law of 1912, which first recognised the amateur status, allotted ‘them all waves below 200 metres, then considered "useless." The keenness of the early transmitters is exemplified in a case quoted by Mr. Maxim, where an amateur, unable to afford the purchase of apparatus, set about constructing a transmitting set from odds and ends picked up.
