New developments in broadcast transmission of such far-reaching effect that apparently closed fields of radio progress are now opened to future exploration have been made by engineers of the Westing- house Electric Company, East Pittsburgh, U.S.A. The develop ments are concerned with a new system of broadcast transmission having an unprecedented operating efficiency. The system as develop ed at station KDKA eliminates three-quarters of the transmitting valves; permits of the broadcasting of a radio valve many times shar- per than heretofore possible; and provides the same range and quality of transmission with less than half the usually required power input. The new system is regarded as ex- tremely important in offering a practical solution to many problems of radio transmission, including the possibility of great reduction in station interference. It opens, too, a new field for receiver design by which Westinghouse engineers foresee an opportunity to overcome static and local interference.

Empire broadenating is the sub- ject of an important statement by the British Broadcasting Corpora- tion, in which it declares that it is definitely committed to play ita rightful part in that regard, but it declines to accept premature and unsound proposals which would certainly retard and prejudice the fuli attainment of the objective.
