WIRELESS INVENTION

HIGH TOAVERS NOW OUT OF DATE.

New York, November 20. The wireless invention will make high receiving or sending towel's unnecessary. —Aus.-N.Z. C'a'ble Assn,

[Mr. Mulholland, representing the Amalgamated Australian Wireless Company in New Zealand, explains that "statics" is the technical word for atmospliwic disturbances, which constitute an enormous interference with wireless telegraphy, particularly in the tropics. Ho illustrated what the effect of a bad "static" was liko one man trying to speak across a room to another, with a lot of other people talking in_ tho room .at the same time. On a good night when the atmospheric disturbances are not in evidence it would be as though no one was speaking in that room except the one person. "Statics" are a particular nuisance in the tropics, and even in these latitudes in the summer they cave a good deal of troublo by blurring the definition of the dots and dashes, making it difficult to iread or receive. If the reported invention is authentic —Mr Mulholland says that Mr. Woiguilt is certainly a big man in wireless —it is a wonderful discovery which will mean a big stride forward in wireless telegraphy the world over. In the tropics it has .been found necessary lo erect very high-powered stations in order to trv and overcome the "statics." That is why the German stations found.in the tropical islands were so heavily powered. The lotal elimination of atmospheric disturbances as they affect wirelew will mean that it will only be neccssarv to erect stations of half the power Hint has been deemed to be necessary in the past, and the new device should go a long way towards achieving faultless,receiving, 'it was pretty well known that during the wan 1 , period considerable advances had been mn.de ill perfecting wireless, but it was not deemed advisable to define what thoso advances were. Possibly Mr. Wiegant'j discovery is one of these.]
