Abstract
KDKA, up to March 1, 1925, has been described in previous papers before the Institute. It is the purpose of this paper to bring the history up to date by describing the equipment now in use, both for regular broadcasting and for short-wave international broadcasting and relay work. The short-wave transimiitter, employed for interworks telegraph service, will also be described. It is concluded that from the description given, with the installation of duplicate equipment and switching arrangements made for the transfer of rectifiers, filament-generators, amplifiers, etc., from one set to another, failure from any cause is guarded against and continuity of service assured. Nothing has thus been spared in making KDKA a station that gives the best quality of broadcasting service.
