BEAM WIRELESS.

! DELAY IN INAUGURATION. A SECRET OUT. i i ! .BT CABLE—I'ItESS ASSOrIATION-COFYRIGHT.i i :ACSTEALIAN AND X.Z. CABLE ASSOCIATION.) I j LONDON, January 20. j It-will be at least a fortnight before ! the inauguraton of the beam wireless | service is possible; first, because time is likely to be taken for analysing results for the purpose of determining the period when a stabilised service may best be achieved, and second, because the Canadian experiments with alternate wave-lengths may point to the solution of difficulties to Australia. It is no secret that the Canadian servico is subject to bad fading-out, sometimes for the best part of twentyfour hours. Experts believe that v.i resort to a longer wavo during the>e times will overcome the fading. The theory is being tried out for a tendays. Meanwhile, it is interesting to learn that China is throughout tlm whole day picking up our beam belter than Australia. The explanation is that the outgoing waves are seeking the most direct route of travel from London slightly north of east before finally dipping to Australia. While it is # obviously possible to conform to the requirements of a sevenhours' day's broken time, with an average of a hundred words a minute, experimenters are now aiming to ensure a certain all-hours' service, even if it is at a less speed. Tests show that signals from Melbourne reach London in one-twentieth of a second.
