A Real Pocket Radio -- A now pocket radio which has been developed by a British firm for the Government, but which has numerous commercial applications, has figured in the news lately. The radio is a transmitter receiver, no larger than a 20-packet of cigarettes, with a transmitting range of about half a mile. The set is carried in the pocket, the earphones appears like a deaf aid, and the microphones is concealed under the jacket lapel. The set which is being produced by Tele-Radios has been designed for use with a master set. Mr Michael Kasia, who had much to do with the development of the set, and who demonstrated it for the purpose of these pictures, said large football crowds etc could be controlled effectively.
