RADIO NOTES

THIS WEEK’S HINT. If the volume df your set is reduced' to half wheai the set next fis switched on, the only thing to do is to separate the two aerials, getting them as far apart as possible. Try to make yours rim in a different direction from that of your neighbour’s, auyl try also to increase the height of your aerial still further.

FEATURES OF THE NEW SET Great progress has been made in the wieless yorld i{i the past 12 months and at the Radio Exhibition which opened at Olympia, London, last month, many novelties were to be seep. Among the (features were: — Disappearance of the crystal set. Vost-pocketj set such las is now being used in police experimeaits at Home. Numerous devices for concealing' or disguising the presence of a receiving set in a room. Manipulation which is completely fool-proof. Self-adjusting time «eHs Which will pick up any required station at any required time. Reduced prices. During the last year great pro* gress hfu} lieeu made in, the art of making a w’reless set take its place unobtrusively among the rest of the furniture in a room. One set was fixed in a clock. Another was built into* a section of a woman’s work-basket. One went into the glove drawer of the hallstand. Another was disguised with dummy books jin an ordinary bookshelf. A GERMAN CLAIM.

A German j experimenter claims that he has perfected a valve which requires no “A” current for its operation, depending upon the action of a substance when light is shone upon the valve- So far no details of the new invention have been received but if there is anything in the idea radio so far as out back listeners are concerned, will be simplified considerably. By its elimination of wet and dry cells the new valve would be welcomed eag. erly by the out-back listener. Installed in the home it would only bo a matter of lifting the receiver lid to set the receiver in operation. while after dark a lamp would take the place of the daylight necessary for the operation of the tubes. Such a tube would have a great reception with portable receiver manufacturers. The “A” supply in the portable receiver is the hug-bear of portable radio.

WHAT IS WANTED. The Postmaster. General, says an exchange, has indicated that it is intended, when the Government takes over control of the broadcasting service, to increase the power of IYA, 3YA and 4YA to that of 2YA- Efficiency does not seem to be measured by kilowatts, as 2YA frequently is ho more audible in daylight than 3ZC. Modulation and steadiness are what listeners require most.

STRAY SPARKS. Denmark, which is known as the country with the greatest percentage ot radio listeners, .has now issued a special postage stamp at a price somewhat higher than its face val. no, and the additional receipts are being employed for the purchase of radio sets for the sick and aged. * x- * * Mess Us. (Philips’ London correspondent) states that investigation has shown that more than 2,000 French schools are provided with radio receiving set. A league has now been formd fo r the purpose of promoting the introduction of radio sets into schools; this committee will also negotiate with the broadcasting stations regarding special transmissions. I.n this respect line example of other countries baa been followed. * *• * # According to advice received the Bishop of Oslo recently stated that contrary to expectations, the broadcasting of church services has brought about many churchgoers. .Moreover, a great many of those who are unable to attend church now regularly listen, in to the services at home. ** * » The Jenkins Television,' Company of Brooklyn, has started a daily broadcast featuring television coup led with the regular evening programme. ** * * Comparing tile mode of holidaymaking to.day with that of twenty yearn ago, an Fug lush writer says that the quiet serenity of the countryside is no more. 'Jarring strains of wireless are heard everywhere, and trees are disfigured by having their branches torn down to provide temporary aerials, whilo the branches themselves are along the once tidy lanes.
