THE DAILY BRITISH WHIG OPENING THE WINDOWS OF THE WORLD | "Another Advance in Transatlantic Telephony By R. T. Barrett. "Stand by,New York. Before put- on the next speaker, we're go- ing to open the windows and see if JOU can hear the chimes of St. Paul's." Involuntarily the forty or so mewspapermen who were gathered in ® room on the second floor of 24 Walker street, New York, on the morning of March 7, 1926, glanced At the clock. It was almost eleven. 'Since half-past eight they had heen g and taking part in the first public test of two-way transat- lantic telephony between the United 'States and England. There was a silence as a wall clock flicked off the seconds and its n hand crept around the dial. Exactly on the hour there came to the ears of the Mstening Americans the silver peal of a belf rung nearly Hour thousand miles away-- then another and another until four had been sounded. It was eleven o'clock in the morning in America, four o'- Jlosk in the afternoon in England. {Bor ly had opened a window in c , and St. Paul's had been . within earshot of Walker Somebody had opened other win- downs, to make this miracle pos- similar to those used by operators when on duty. In talking to London, the speaker entered a scund-proof booth similar to those of a public pay-station and spoke into a trans- mitter very much like the ordinary transmitter {in appearance. The mouthpiece and transmitter case were, however, somewhat larger than those of the familiar desk set, this being a special "high-quality" | transmitter. The receiver was of the standard type. | Near the speaker's booth was an- | other, equipped with what was to all | intents and purposes an extension telephone of the same type, at which | sat an engineer of the American Tel- | ephone Company, who kept in con-! stant touch with an engineer of the | British Post Office, working on a | similar extension on the London | end of the circuit.

This radio link is 2,900 miles in length. From Houl- ton to New York, the speech is car- ried over 600 miles of telephone circuits of the American Telephone and Telegraph Company and its As- siciated Companies. The radio transmission from Rocky Point is on a wave length of 5,260 meters, and the transmission from Rugby is on & wave length of 5,770 meters. The power used in transmitting from each end is about 100 kilowatts. Due to a special system employed in these tests, an output to the transmitting antenna of 100 kilowatts is as efficient as 300 kilowatts would be under the system commonly used for radio telephone purposes. One of the fea- tures of this system is the suppres- sion of all waves except those ac- tually transmitting the message. This systefn was described in many of The Bell System magazines in an article on the one-way transatlantic telephony test of January 14, 1923, When officials of the American Tele- phone and Telegraph Company talk- ed tor a period of over two hours to listeniers in England. . - That and other articles have alsq power, t part in de- output described fn some detail the high- | : vacuum tubes | factory a phase of the study of the problem of overcoming the great difficulty in long distance radio telephone trans- mission--the extreme variations in received signals due to continuously changing conditions in the inter vening space. At times, transmission conditions in America, in England and through- out the area that separates them are 80 good that even comparatively low power broadcasting stations in one country can be picked up by radio listeners in the other. At other times conditions are so poor that no recep- tion can be had. The longer wave lengths and the high effectiveness of the transmitt- Ing stations used in the present 'tests have provided a stability and transmission, of which those brief- ly outlined above are only two, there are others which may be described as practical operating problems, such as linking the radio with the regular wire telephone systems of both England and America in such a way as not to introduce undesir- able noises, weak reception or other factors which would impair the Quality of transoceanic service, In their statements to the press, telephone officials of both countries have made it clear that it is not possible to predict how soon rrans- oceanic telephone service can be 'made available.
