A ERIA LIS MS

Variable condensers should be kept clean. Mysterious troubles may develop if no attention is given to this matter, especially where the higher voltage goes directly across the dates of the condenser. Dust particles accumulating on the vanes may become conductive, and cause much noise, and .sometimes even flash-overs. The easiest way to prevent this trouble is to blow hard through the plates, or to run a pipe cleaner between them

The rebroadcasting of short-wave programmes from far-away foreign countries is going to be an increasingly noticeable feature of all stations which are on the air for entertainment and experimental purposes, and will no doubt be lhade use of by the New Zealand stations during 1930 to a greater extent than in 1939. There are very many short-wave stations in the world, but they are all more or less in the experimental stage, though a fair number of them give regular scheduled broadcasts with much success.

There is no end to radio prophets, and just as many different opinions aifioug them. Wireless has advanced - with such rapidity that people are apt to think anything possible. While revolutionary improvements are always within the bounds of possibility, ’ there is nothing at present on the radio horizon to suggest that we are on the eve of something big. Television and home radio talkies are ; coming, but apparently as separate units, and not as supplementary ad- , juncts to the receiving set. We may j see some fair television demonstra- ; (ions next winter, but they will not. I however, affect the regular radio reI ceiver. Television is an added service, and when It is ready, probably because of electrical and mechanical j complications it will be an entirely separate unit. Except for the experienced experimenter, television may be dismissed for the present. Home radio talkie movies are just another complication of television. They are bound to come—inevitably and costly, both of them.
