Show CONCERTS THROUGH THE A1P, Enjoyable Musical Program That Emanates From Doctor's Radio Experimental Laboratory. War bulletins and important world happenings, now and then interspersed in a nightiy musical program from the air, emanate from the radio experimental experi-mental laboratory of Dr. Lee DeFor-est DeFor-est at Highbridge, N. Y. Among the musical numbers on the nightly program pro-gram are operatic selections, popular dance music, sentimental songs, Hawaiian Ha-waiian medleys, and stirring band and orchestra phonograph offerings. In point of clearness it is. said that the xylophone and the accordion are among the best instruments for wireless wire-less transmission, although the brass band and the human voice, especially if soprano, ofttim.es are equally clear to all the listening amateur stations. To transmit the 'human voice by wireless wire-less telephone the speaker or operator opera-tor talks into an ordinary microphone. In the case of the musical selection, on the other hand, the. microphone is placed inside the cabinet of a phonograph, phono-graph, where it can get the full volume vol-ume of sound.
