What of 1928?

H® following is how David Sarnoff vice-president and general manager of the Radio Corporation of America, sums up the achievements of 1928 :- The radio art in 1928 largely emerged from, the period of discovery to the application of electrical and engineering principles already developed in the laboratory. Chief of these developments was the perfection of the A.C. valve, The use of radio in the home has been reduced almost to the simplest terms, The new A.O. valve has stabilised the operation of the modern receiving set. A practically inexhaus: tible source of power has been made available for radio from the electric light socket. Problems of installation, operation, and maintenance have been simplified. Other refinements have been in the direction of unicontrolled tuning processes and better tonal qualities. Further fundamental progress in radio must await the results of continned research into the wave channels of space.. Our vision has been widened by the exploration thus far -# abortwaye channels, But there are

many problems to solve. We have not yet plumbed the full possibilities of shortwave transmission. Until research determines the best channels of transmission and experiment teaches us how best to utillse them, television, despite technical progress made, must remain primarily a laboratory development. Demonstrations made during the year, however, showed marked progress in the electrical and mechanical components of sight transmi-c>ion.
