THE RADIO DEBATE WAS INTERESTING.

The 3YA-4YA Stunt. Although some listeners may have missed the ordinary band presentation, from 3YA last night, its place was well tilled by the Varsity students’ debate carried out between 3YA and 4YA, betwe< n S and 9.40 o’clock. All the speeches were heard clearly and well, and the unique experiment can be voted a decided success. As a debate, it was pleasing to note the ready wit in reply, and the evidence of not only wide reading, but also of close study and keen observation on the part of the debaters on. both sides. The best portion of the session was heard when Mr J. B. Calland, Dunedin, followed lUs announcement of the award by bis criticisms of the manners and methods of the debaters. He is a clear speaker, and his remarks were very interesting. Poor Caruso had a bad time of it from all hands! Tried 4YA direct several times during the evening, but reception thus was pot to be compared witli 3YA’s relay of the southern station. Both static and fading were troublesome on 460 metres. Other Stations. Static, in short, crisp bursts, was noticeable on all DX transmissions (except on 2YA), when the rounds were made after 9.45. The Wellington station exhibited good volume, with only a trifle of static audible. A very good transmission on the whole was that of 4/.L Dunedin. At times volume was truly wonderful, considering the low power of this station, j and, although some static and a little j fading intervened occasionally, reception was well worth while. Despite the “shots” every second or SO from static, all the Australian tain manner. 2FC was particularly strong, but the others were not very far behind in volume. Television in America. A theatre audience at Schenectady, I N. V., recently paid the regular admission prices to see a Vaudeville performance transmitted by wireless from a General Electric laboratory, half a mile away (writes a contributor to “World-Radio." ..f June 13). The test, which was made with the apparatus of Dr G. If. W. Alexanderson, showed a gr -it improvement over previous experiments. Three years ago, Dr Alexander - son, at St Louis, exhibited an image hi a three-inch aperture. Last year he projected an image fourteen inches square at Madison Square. Garden. New York. On June 4, however, his audience saw picture projections on a screen thirty-six feet square. Only the head and shoulders of the performers were Visible. Definition in the centre of the screen was fairly sharp, hut towards the edges tne images faded. Marring the image were parallel lines of “rain” running along a horizontal arc, and, in one or two instances, there were wide blurs. In an interview. Dr Alexanderson said lie was experimenting with television over short and long distances—nainciy, over a two-mile stretch. and between Schenectady and Australia Over the longer stretch, he said, reflection faded constantly and multiple images were the principal obstructions in the way of successful experimentation. He explained that the photo-1 graphic images of the performers were converted into radio signals, and, in the case of the. Schenectady theatre experiment, transmitted on Mo-metre wave In his own words: “The performers stand before an incandescent lamp. Between the subject and the source of light is a metal scanning disc the size of a bicycle the outer eir-umf.r-tw. nly times per second—thaVYs, twentv half-tone pictures are built up each Seeoml. Four Photo-electric cells tinker 40.0ne times per second in response tic image. Once the light is converted into radio waves it is broadcast into .spare from an aerial, and may |,o ph-k----ed up on appropriate receivers.” The future practical use ot television was indicated by Dr Alexanderson, who said “Television cannot compete with tin s I:ar p definit a.n_ of cinema cameras. But

cessary,. as with a boxing match. or football game. We hope expectantly to see television take a part in the next Presidential election.”
