RADIO NOTES

DEVELOPMENT OF TELEVISION SERVICE MUST GROW GRADUALLY The early history of television will necessarily differ from that of sound broadcasting for two critical reasons—there is no apparatus for receiving television comparable in simplicity and cheapness with the crystal set, and the range of stations is limited by certain physical factors over which engineering can exercise no control. For these reasons television cannot hope to grow with the incredible rapidity With which broadcasting covered Great Britain and the U.S.A. in 1922 -and 1923. When television programmes .from the new 8.8. C. station at the Alexandra Palace start this year they will be capable of reception only by people, in the London area. In addition, these programmes will be experimental in every sense of the word.

Apart from the many technical problems attending the inauguration of a regular service by methods as yet comparatively untried, the programme side itself is virtually a virgin field. Both the resources and the limitations of high-definition television have yet.to be explored. It may be some time before teicvision ■becomes ; more than a. luxury supplement to' sound broadcasting. The Television Committee estimated that 10 ultra-short wave stations would be necessary to serve 50 per cent of the population, so it is obvious that the one station at the Alexandra Palace will possess onlv an academic interest for the bulk of listeners. QUEEN MARY’S MAIDEN VOYAGE Next May the Queen Mary is to sail from Southampton on nor maiden voyage to New York, and again broadcasting will cater for the public interest that the voyage will arouse. The Queen Mary will carry a flying squad from the 8.8 C.. with microphones placed at strategic points throughout the complicated structure of the big ship. From the time she sails.to the time she docks in New York, British listeners will fie in daily contact with her They will he a!-Je tr hear at first hand what progress she is making, and how life goes on among the thousands of people on board. From engine room crew to-crow's nest' the mi ernphones will convey an impression of the multifarious activities of passengers and crew. If the many technical difficulties can lie overcome, such a series of relays should substitute a new achievement in broadcast mg, combining entertainment and news with al! "lie interest of “actuality'’ and the thrill that broadcasts from mid-Atlantic can rtiil bring. At all events, it is certain to be one, of the most eagerally-nwaited events in tlie broadcasting of 1936, for here, surely, is one of the things that only broadcasting can do. . , RADIO VAGARIES . Tim vagaries of radio were strikingly illustrated in the recent stranding .<> the. small launch Donald Sutherland on Farewell Spit, near Nelson. The launch whs equipped with a small transmitter of, 20 watts input rating, or rather less |han half the wattage of an ordinary

•receiver. The aerial output was litt.Ve more than five watts, but, in spite of a short and very low aerial, the craft was able to maintain communication with Auckland over distances of approximately 500 indes, although quite unable to con munieate with Wellington, about 50 or 60 miles away. This was due, it is assumed, to the screening effect of the high hills around Wellington. The position i.s the more remarkable owing to the fact that the transmissions were on 600 meters, not the best wavelength for long’distance low power communication. NEW TRANSMITTER Work is progressing satisfactorily at Titahi Bay, where the new 60-kilowatt transmitter for 2YA is to be established. The contract for the necessary buildings lias been let and the manufacture of the transmitting equipment is proceeding in the workshops of Amalgamated Wireless (Australasia), Ltd., at Sydney. It is expected that the new transmitter will be brought into service before the end of the present year. SHORT.WAVES AS A CURE Ultra-short wireless waves arc being used by Dr. William Dieffenbach to cure the common cold. “It was discovered,” runs, the report, “that although wireless operators work in close, confined quarters they rarely get a cold. At the same time nearly all wireless operators experience a feeling of congestion in the head when off duty. Investigations showed that this feeling was due to abnormal condition of the blood, caused by the ultrashort, waves. Consequently it was proved that waves actualv act as a warning t# the white corpuscles to be ready to attack and keep cold germs at bay.’ ’
