WIRELESS EXPERIMENTS

WORK ON ANGLE OF BEAM INVESTIGATION BY AMATEURS. IN AUSTRALIA-AND AMERICA. United Press Association —By Electric Telegraph Copyright.) (Australian Press Association.) Received 10.30 -a.m. to-day. NEW YORK, Oct. 31. A message from Hartford, Connecticut, states that radio amateurs in Australia and United States will participate in an interesting experiment at two o’clock on the morning of November 1, Eastern .standard- time, when tests of transmission between the two conitinemtis will -be made on a ten-metre wave length. The trials are sponsored by the American Radio- Relay Leaigue, and will last one week. The principal difficulty on oj iten-mofre length, is in the angle of the beam, and Mr E. C. Crossett, of Chicago, 'hois created a new -transmitter ait his summer home, Wiarnno (Massachusetts), from which the tests will be made. Instead of the angle of the beam being varied horizontally, the beam is variable on a vertical plane: The direction is on the great circle to Australia, and it is fixed metrically, so a® 'to shoot the -beam 'off in a long tangent, fpraet icaiUy patraj-lel -to -the surface of the earth, Or to any angle up to vertical. The angle of the beam will be varied constantly in an attempt to find an angle at which communications may be established with Australia- on a. regular basis.
