WIRELESS WONDERS

BEAM SYSTEM TO AUSTRALIA COMPLETED

SHOULD BE OPEN IN FEW DAYS

RADIO PHONE TESTS IN FEW WEEKS

(Received Jan. 11. 8.30 p.m.) LONDON, Jan. 10. As the result of a three days’ test with, the Australian _ beam system during the week-end, Marconi maintained a speed of three hundred words a minute. They therefore are dispensing with the seven day test as was the case with Canada and will hand over the system to the Post Office on Wednesday for a week’s test.. If this is satisfactory, the service will open immediately. It is understood there is no hope of a variation of the decision that the charges will be two-thirds of the cable rates at the time the contract is signed. It is understood also that Marconi has offered to begin wireless telephony tests to Australia within the space of a few weeks, but the Post Office wishes to concentrate on the perfection _of wireless telegraphy first, and also to profit Ijy the experience of the complexities of telephony with America. For instance, in yesterday’s trial with Ottawa, the London speaker’s words came back as an echo in his ears in a few seeonds. The elimination of this, and also the achievement .of complete secrecy are problems to lie solved. The records show that both South Africa and New Zealand heard, talks with America, but only isolated snatches of one voice only.

“We are confident that a year lienee wireless telephony to Australia will be in operation as a commercial proposition. It may be erratic at times, but will be quite workable at certain periods of the day. We think a short wave length will facilitate it. Furthermore, it is a hopeful sign that the short wave service to Cairo goes on when the trans-Atlantic service completely fades out.” This was the opinion expressed by a high official who is in daily touch with all experiments. —A. and N.Z.C.A.

WIRELESS PHONE FROM ENGLAND TO MONTREAL

SUCCESS OF SHORT WAVE SEAM SYSTEM.

LONDON, Jan. 10.

Tlie Marconi station at Bridgwater established telephonic communication with Montreal, using the short-wave beam system. There were practically no atmospherics or fading after sunset as experienced in the New York service.

The Daily Express says experts are recommending the beam system to ensure the secrecy of trans-Atlantic telephony, though they admit a fanshaped beam would create a fairly wide band of audibility at . some points.—A.N.Z.C.A.
