WIRELESS FOR EMPIRE.

DEVELOPMENT AT HOME. PROBLEMS OF BROADCASTING. Sun. LONDON, Aug. 31. Mr. Anthony Hankey, representative of tho Wireless Association of Britain, says the chief engineer of the Marconi Company told him Empire broadcasting would probably be developed along the lines of a compromise between the be-irn system and broadcasting by a new system retaining the power and conserving the virtues of the beam while covering wide areas. Tho engineer plotted on a map of the world what ho 'thought tho eventual solution of Empire broadcasting problems would .be, namely, a short-wave station in England having three apertures varying in width. Tho first would be 120 degrees, sending out. waves to cover tho Pacific Islands, Australia, New Zealand, the Far East, India and Ceylon; tho second would be 60 degrees, covering tho whole of Africa, and tho third 75 degrees, covering Canada and the West Indies. It would bo possible for such a station to broadcast over any of those areas, or over tho three simultaneously by conserving the energy which ordinary broadcasting dissipated. A low-powered, inexpensive station could be used. Marconis are at preseut experimenting in superimposing speech on the existing beam service to Canada. The company proposes to carry out similar experiments with South America before developing beam broadcasting. The British amateur, Mr. Gerald Marcuse, is continuing the adjustments of his apparatus. He has received cables from various parts of the Empire announcing excellent reception of his broadcast on August 20. A further experimental broadcast Avill bo sent out on September 4, prior to beginning Empire broadcasting proper*
