NEW WIRELESS'AGE

MARCONI'S PREDICTION NO MORE INTERFERENCE - SOUNDS WILL BE CLEARER ABSENCE OF ATMOSPHERICS By Tcletcraph—Press Association— Copyright (Received May 30, 8.55 p.m.) •LONDON, May 30 A new wireless ago was predicted by Senatoro Marconi in a special Interview witli a representative of the Daily Telegraph. In this new age, he said, there would be no congestion and no interference from storms, steel buildings, lifts or refrigerators. Moreover, voices and music would have a clarity unknown to-day. Discussing his latest discoveries, Senatoro Marconi said it should bo possible to broadcast on a wave-length of 50 centimetres over a radius of perhaps 20 miles. Already ho had transmitted speech by beam on a micro-wave-length over a distance of 168 miles. The advantages of the micro-wave wore freedom from interference, clarity of reception, absenco of atmospherics and fading and increased scope for independent broadcasting. There could l)e as many stations between wavelengths of 20 centimetres and one metro as there were at present between 200 and 1000 metres.

"It appears as if the curvature of the earth and the obstruction of solid objects has been overcome," said Senatore Marconi, "but I am not certain whether wireless waves travel over or through the obstructions. Probably if a hill is dry enough the waves travel through it. "Micro-wave telephony by beam already is in use as a commercial proposition in Italy. I have come to the conclusion that waves between 40 and 50 centimetres are the most useful." Senatore Marconi is on his way to Cambridge University to receive a degree.

EMPIRE BROADCAST SPECIAL TEST ARRANGED RECEPTION ON FRIDAY [BT TEIjKGRArH OWN" CORRESPONDENT] "WELLINGTON, Tuesday The British Broadcasting Corporation announces that a special test transmission will take place from Daventry, the Empire short-wave station, on 25.53 metres to New Zealand and Pacific listeners on the evening of Thursday, June 1. This will be received in New Zealand between the hours of 5.30 a.m. and 7.30 a.m., local time, on Friday. "We are particularly anxious to receive the co-operation of short-wave listeners," explained the 8.8.C. representative, Mr. Malcolm Fi'ost, who is visiting the Dominion on a special mission connected with the improvement of the Empire radio service. "Reports addressed to me, care of the Post and Telegraph Department, Wellington, will be of the greatest possible value, and an analysis of their contents will be cabled to London for the information of the engineers.

"At present the transmissions from Daventry which take place at this time are 'beamed' on South Africa," said Mr. Frost, "but we have been amazed to find that, contrary to all expectations, these transmissions have been received with some degree of success in the Antipodes. Should the test be of value we shall have to examine in Loudon the possibility of transmitting a regular service to New Zealand and the Pacific some time between 6 a.m. and mid-day, local time."
