Radio Telegraphy in Competition with Wire Telegraphy in Overland Work

After considering some of the obstacles in the way of successful competition of overland radio service versus wire service, the author treats the mode of overcoming these difficulties. He recommends also radio duplex circuits; reception with loud-speaking receivers and amplifiers; trunk and way circuits from large radio centers of traffic; and relaying stations. The organization and operation of the Pacific coast chain of duplex radio stations of the Federal Telegraph Company is then described in detail.
