WIRELESS WONDERS

AUSTRALIA-AMERICAN TWOWAY COMMUNICATION. AUSTRALIAN RECORD FOR TWO-WAY- WORK. RESULT OF TEST WITH GISBORNE OPERATOR. MELBOURNE, Not: 5. For the iirsL time a wireless operator, Mr Howden, has established a two-way wireless communication between Australia and America. On Monday night Mr Howden had <rrauged a test with an experimenter at Gisborne at 7.1.5. At seven iio sent out a general call. In a few minutes he heard an American, Mr Williams, at Yamona, California, answering. Messages were exchanged for forty minutes. Arrangements were made for a further trv-out. Mr Howden used a wave length of eighty six mcfcrbs, his power being 120 watts. The American’s wave length was seventy-five metres. Hie Gisborne man with whom Mr Hodwert had an appointment, and several other,. New Zealand experimenters, heard the exchange of messages with America.—U.P.A.

AIR IVAN O’MEARA HEARS CALLS GISBORNE AMATEUR’S GREAT ACHIEVEMENT The Gisborne experimenter mentioned in the message was Air Ivan O’Meara, who succeeded in exchanging signals with the Melbourne amateur whose station is 3BQ. Working on a wave length of 83 metres, Mr O’Meara caught SBQ’s signals quite plainly and was in communication with Mr Howden for some time. This is the first time, says Air O’Meara, that an Australian amateur has.been successful in .establishing two-way communication which they have been essaying for some time past. Station 3BQ which is Air Maxwell Howden’s of Boxhill, Melbourne* has often been in communication with Air O’Meara with a Gisborne amateur, Air R. Patty, operating the plant. Air O’Meara has the achievement of communicating with nine American one British, one Chilian, three Argon tine and one Uruguayan stations. Jn addition he has been in communication with two French stations, the signals of one being particularly loud and easily distinguished. Altogether five English stations have been worked by different amateurs in New Zealand during the past week or so, but this week the stations made signals very indistinct and communication was practically impossible. BEAM WIRELESS. EFFECTIVE DAY AND NIGHT AND AT ANY DISTANCE. (Received Nov. 5. 5.5 p.m.) LONDON, Nov. 4. Alarconi lias returned after an absence of three months’ experimenting with beam wireless aboard his own yacht. He announces that beam wireless is equally effective day and night, and at any distance. —A. and N.Z. C.A.

POLICE UTILISE WIRELESS

BRIDEGRCOM APRESTED

CHARGE OF MURDER

SYDNEY. Sept. 13. Wireless is only being tested for police use, but the provision of a set on the police night patrol car last Sunday morning was directly responsible for swift action 1 , and the arrest, on a charge of murder, of a bridegroom of a few hours. Robert Walker, a married man, of Taylor Street, Annandale, was killed and Alfred Alitehell. 29, and Frank Smith, 24, both of Annandale, were severely injured as the result- of a motor accident on Parramatta Road late on Saturday night. The car which knocked down the three men disappeared a few seconds after the smash and a pedestrian who heard the noise came on the scene to find the three men lying on the roadway. Walker’s neck and both legs were broken—he had been thrown 100 feet by the impact, while both the others had fractured skulls. . ’lhe alarm was given to Police Headquarters and the wireless messag sent out. lit reached the patrol at Alexandria and within five minutes the police were on the spot. Three cars had been seen iff the vicinitv about the time- of the accident, and- it was only a matter of a few minutes before two of them had been ele-ared of any participation in the affair. Further wireless messages were sent and received, and then the patrol ■ visited Westbourno Street, Petersham, where the owner of a motor car was interviewed. He denied all knowledge of the matter the police were handling, though ho admitted that he v<as“near the spot at the time. He said he had been married! at 7.30 p.m. on Saturday, and wefft for a spin with his wife and two other men. "They met with an accident but did not run down any pedestrians.

The police sergeant was not satisfied, and examined the car, which showed unmistakable signs of art accident, both headlights being damaged and the mudguard bent. ■Close scrutiny showed traces of blood, and eventually one of the younger members of the party is alleged to have confessed that t:iey did run down the three men, and that, after the accident, all traces of the- blood, they thought, were washed away, and the other-story concocted. The: bridegroom of a few hours was arrested, and charged with having feloniously slain Walker.

WIRELESS-RUN MACHINE, CONTROLLED FROM 170 MILES AWAY. A Daily Mail representative L Manchester on September 3 pressed the button of a wireless transmitting set. At the same time a crowd of spectators in the Palace of Engineering at Wembley’ saw a 650-h.p. machine begin to work.

For the first time massive commercial machinery has been started by wireless. The experiment was conducted by The-Daily Mail in conjunction with the Metropolitan-Vickers Electrical Company. The signal sent out from Manchester, 170 miles away, was picked up by an aerial on the roof of the Palace of Engineering and transmitted to a switchboard that controlled the machine. The aerial was also connected to a loud-speaker to enable the public to bear the signal. , Five minutes later another signal was heard through the loud-speaker, live of six lighted panels wept out, levers clanged noisily again, and the machine came to rest.
