BEAM WIRELESS

AUSTRALIA'S SERVICE NOT THOUGHT SUITABLE FOR TELEPHONY London, May 30. It is understood that there is little chance of Australia’s beam wireless being in operation for four or five months, because considerable technical difficulties remain to be surmounted. Canada will be ready to operate at the end of July, when it will afford a criterion of the prospects of the Australian service It is suggested in some quarters that sufficient plant has been installed at Grimsby and Skegness to permit of short wave experiments with Australia as a preliminary to the beam service On this point it is interesting to recall that the Government commercial service is going out nightly from the Dollis Hill experimental station, which cost a mere bagatelle and is using one kilowatt, on a wave-length of 17 metres. Its messages are regnlarlv picked up in China, Australia, and New Zealand. Experts hold out only the slenderest hope of the beam station being adapted for telenhonv, because in telephony short waves produce a most pronounced •mutilation compared with the long . waves used in the Rugbv tests. Experiments are proceeding with the latter station to secure ‘ complete telephonic secrecy, and progress liitherto has been most promising.—Aus.-N.Z. Cable Assn.
