FLEET TESTS RADIO PHONE.
Wireless Experiments Successful In Winter Manoeuvres.
Special to The New York Times.
WASHINGTON, Jan. 30.--Important experiments in radio telephony are being conducted by the Atlantic fleet during its Winter manoeuvres off Cuba. These are the result of the successful outcome of experiments carried on for the past year by the American Telephone and Telegraph Company and the Western Electric Company in co-operation with radio stations under the jurisdiction of the Navy Department by which long distance wireless telephony has been made possible.
On Sept. 29 last the human voice was wafted 4,600 miles in messages sent from New York via the navy radio stations at Arlington, Va., and San Francisco, Cal. to Honolulu. A little later wireless telephone conversation was sent from the radio station at Arlington to the Eiffel Tower in Paris. Now the experiments are being carried a step further in an effort to ascertain the military applicability of the wireless telephone to the work, tactics, and strategy of a great battleship fleet.
In these experiments radio-telephone transmitters have been installed on the Wyoming, Admiral Fletcher's flagship, and on the Texas. These transmitters are being used in sending messages to the other units of the fleet, which, while not equipped with the telephone transmitters, are able to receive the messages by radio-telegraphic sets.
Lieutenant William R. Furlong, the fleet radio officer, has reported that the experiments have been successful.
