Bureau of Standards' Radio Work
By J. H. DELLINGER
AN ALMOST UNLIMITED FIELD FOR RADIO TELEPHONY.
One of the interesting uses of the radio telephone was demonstrated at the Bureau of Standards a few weeks ago at an evening lecture and social meeting. The radio telephone apparatus was shown. Messages transmitted and received by the device. In addition music was received in the lecture hall by radio from a talking machine which was being played at the transmitting station at a distance. Now the waves which carry this radio music spread out in all directions as do all radio waves. Consequently not only the receiving apparatus in the lecture room, but any receiving apparatus within a radius of several hundred miles was able to catch this music. In fact, after the demonstration, word was received that this music had been heard in another town. An unexpected result was obtained when after the music rendered by the talking machine had been finished "The Star Spangled Banner" was played by a cornetist at the transmitting station. The audience in the lecture room immediately arose and after the performance applauded. The performer never knew that the applause had been given and never knew whether his performance had even been heard. Later in the same evening some of the people danced to the same music. This suggests the great economies that will be effected in the future in the matter of musical entertainments. A symphony orchestra or any other musical performance can be given at one central point and sent forth by radio so that it can be received anywhere else in the United States. One performance then will constitute the evening's entertainment for the whole country. This is Edward Bellamy's dream come true.
Out of the wreck of war much of what was done in the application of science is being salvaged, more perhaps than is ordinarily realized. In the great development of radio communication there is a distinct asset which is now being turned to the peaceful uses of mankind. Radio is not so much a separate as a supplementary means of communication. The ordinary wire-connected telephone will handle 99 per cent of the exchange of speech, and the radio telephone will supplement it, carrying men's words and thoughts to the uttermost parts of the earth, air, and sea.
