Micro-Wave Test

MARCHESE Marconi has reported to the Royal Academy of Italy that he had succeeded in transmitting microwaves through a distanc’d of 150 kilometres, or 93£ miles, during recent experiments on board his yacht Elettra. Senator Marconi said: “I was able to make further trials iu telegraphic atnl telephonic radio transmission by means of micro-waves of about (30 ‘•-ont-imetres. The tests were between a transmitting apparatus at Santa Marghcrita Ligura (near. Genoa) and the yacht Elettra, which moved along tho coast. “Though the distance over which one would expect reception was only 30 kilometres, the transmissions were received on the yacht with great force and regularity at a range of 150 kilometres. Last year the greatest distance .over which reception could be effected was only 52 kilometres. “Feeble Morse signals were per- 1 ecptible as far as Port Santo Stel'ano, a distance of 25S kilometres. High mountains intervened between our two little stations. The better results appear , to be due to the improved efficiency of the transmitting and receiving apparatus and of the reflectors used.”
