RADIO PROGRESS

IMPETUS OF THE WAR

Under the impetus of war, radio and electronic techniques performed services in the last year that were deemed impossible in ;940, declared Brig.Gen. David Sarnoff, president of the Radio Corporation of America, in a statement reviewing progress in 1944. As a result a new era of communications is opening, he said, in which science has endowed radio-electronic fingers with a new sense of "control at a distance." Just as television now enables us to see at a distance, after the war, by the use of "television techniques," we will be able to reach' out into space and control many of the functions that can be seen.

"Man has long dreamed of using radio to start, steer, control, and operate aircraft, tanks, torpedoes, automobiles, boats, and other objects," he said. "Wartime research has made some of these dreams come true."

One of the 1944 developments still on the secret list, he said, is a "300----megacycle television transmitter," described as the first of its kind developed to use five kilowatts. It had come about through the development of a special electronic tube and associated circuits. Full use of the unit, he said, must await the end of the war.

Electronics, he said, had been employed successfully in the large-scale Production of penicillin.
