DECIMETRE WAVES
IMMUNE FROM ATMOSPHERICS GREAT ADVANCE IN WIRELESS (United Press Association.) (By Electric Telegraph—Copyright.) BERLIN, June 25. (Received June 26, at 9.30 p.m.) The German Telefunken Company announces that experiments begun in 1933 with decimetre waves—namely, from 10 centimetres to one metre, have now so far advanced that it claims that waves can be transmitted in a straight line to a given destination without possibility of detection by anyone outside the line of transmission. They are also immune from atmospherics and other interferences, and will be of immense value in wartime. Even if decimetre waves of the same wave-length are used by different stations interference can be eliminated by turning the apparatus in the required direction. While the magnetroh gridless valve is no bigger than a thumb it has solved certain reception problems. A demonstration to-day showed that the waves can be used to assist in guiding ships and aeroplanes by the craft keeping a path directed by the ray.
