TRANSATLANTIC BROADCAST|NG
 NOW LOOMS UP
Successful Test by Newark With London Has Opened Up Promising Possibility
 for Near Future

The special test carried on last Sunday night, when receiving sta- i tion in London successfully heard music radiated from Newark, N. J., forecasts the wonderful possibilities which are the immediate future of radio broadcasting. These are still i further emphasized by the successful broadcasting of the worlds series baseball games direct from the Polo 1 grounds.
 According to the report cabled over by Gordon selfridge, upon whose store in London the receiving set was installed, the actual reception of the music and singing was marred somewhat by Interference from wire less telegraph apparatus on ships around the British coast. This, how ever, was to be expected in the ini- tial test-the remarkable thing being that music should have been heard in view of the small amount of pow CT used at the broadcasting station.
 The test is far more wonderful than was the special test conducted i, across the Atlantic ocean last Decem- Der by the amateurs of this country. | Although the amateurs used no 1 greater power than was used by the | Newark station, their tests consisted 1 of telegraph messages transmitted in 1 dots and dashes.
 Telephone Covers Less Distance 1 To understand the difference one must understand that with dots and l dashes steady current of unvarylng l power and amplitude Is being radi- ated from the transmitting station. In the case of radio-telephone transmitting station, however. the | IF.& L. | varying amplitude of the human voice, and consequently the average | strength of the signals radlated Is really no greater than the weakest tone in any particular word, or mu- sical note.
 It can be still better understood if we take for granted a fact that has l been daily demonstrated by actual ] experience, namely. that radio-tele- phone can cover only one-fourth of l the distance that can be covered by radio-t telegraph with equal power. l In fact, if the same transmitting sta ton is used for both purposes, it 1 will cover four times the distance when used as a telegraph station
 The test of Sunday therefore is in- ] deed remarkable.
 From the point of public utility.
 the success attained by this initial l performance opens up new field of
 vast potentialities in international
 association. It gives promise In the
 near future of broadcasting all inn | portant world events over the Euro pean and American continents sim | ultaneously
 International Broadcast Soon
 An idea of the importance of this
 can be gained by considering the 1 present Near Eastern crisis. The
 time will come in the near future when the debates of the British Par liament, the French Chamber of Dep- 1 uties and our own Congress will be l broadcast from powerful government owned transmitting stations and | picked up and reradiated by other
 radio-phone stations in different
 parts of the civilized world.
 There Is no reason in the world
 why these broadcasts should not be
 transmitted across the Atlantic | ocean. The recent development of
 high power vacuum tubes has opened
 up the way for this possibility, and 1t
 is only a question of time before
 these tubes will be put into actual
 operating conditions for testing pur-
 poses.
 There is not the slightest doubt that radio has broken up the last
 remaining vestige of isolation, and it's scope is widening more and more every day. The broadcasting of the | worlds series at the Polo grounds, following upon the successful broad Icasting of the Philharmonic concerts lin New York City and the two Leon
 ard championship prizefight, has clearly demonstrated how well the radio can be hooked up to the existing telephone lines for the purpose of radiating events of special outstand- ing national or international import ance.
 Will Bring Peoples Together
 The time is not so far distant when the voice of some new wonderful 1 singer discovered in one continent will be presented to the residents of | another part of the world by means of radio phone broadcasting long be- | fore the singer could possibly go there. Aside from the entertain ment possibilities. however, the im- portant thing is the bearing such development will have upon interna- tional relations. It will undoubted- | ly go a long way toward elimi- lnating those little jealousies and mis- understandings which pave the way to wars. by bringing the peoples of two countries into closer relation ship to each other.
 Of course we are only on the verge
 of this extension of radio broadcast ing. At present it is but a possibility but 1t has every assurance of ulti- mate achievement. and the test of Sunday is a promising beginning. There is quite a lot to be done in 1 the engineering line before trans Atlantic broadcasting can be accom- rlished, but none of the obstacles facing the engineers Is insurmount- l able. In fact, the most serious one has already been removed through the development of the vacuum tube capable of producing 100 kilowatts of | power.
 Under the circumstances, therefore, 1t Is merely a question of refinement and adaptability of present instru- mentalities to meet the special con- l ditions which will have to be over ] come in bringing about trans-Atlan- tic wireless telephony Not only will the transmitting apparatus have to be still further developed. but the receiving equipment will also need some attention. The strides already made. however. during the present year have been really astounding, and they augur we'll for the future of international broadcasting. 1
