CRICKET TALK POSTPONED

The initial talk from IYA by C. C. Dacre, former Auckland and New Zealand cricket representative, has been postponed. It was to have been given on Thursday evening, the subject chosen being "The English Tour of Australia." A talk by Sam Gudsell, champion walker of the Dominion, will be broadcast to-morrow evening at 9.2. He will speak on "Famous ex-Auckland Athletes."

NEW EMPIRE STATION

Preparatory to a regular nightly service, a test of the British Empire radio station, GSD, at Daventry, England, was received in New Zealand last week. A member of the New Zealand Shortwave Radio Club, who heard the transmission, said that the new station was on 25.53 metres, the same wave-length as that which had been used by the station at Chelmsford. Last week's experimental programme consisted of gramophone records, which were heard in good volume but were distorted. There was a strong ripple, but this would be remedied.

In good conditions the Empire station might be received almost as well as the local one. The power in the aerial was 20 kilowatts and directional antennae were used, the wave-length being the same for the different parts of the Empire. The station is to begin transmissions to various parts of the Empire on December 19, the daily session for Australia and New Zealand being received in New Zealand between 9.30 and 11.30 p.m., daylight-saving time.

S.O.S. BROADCASTS

A summary prepared of S.O.S. messages broadcast in England during the first half of 1932 shows a marked increaso in numbers. The total for all stations was 493 for the six months, as compared with 833 for the whole of last year. There was a considerable increase in the number of messages for missing persons, which was 191 for the half-year, as against 270 for the whole of 1931.

In all classes of messages, except those dealing with witnesses of accidents, the percentage of successes was rather higher than in 1931. Among the unusual cases was that of a girl who went to a hospital to be X-rayed after swallowing a pin and ran away while the X-ray photographs were being developed. The doctor found that she was in grave danger, and asked the/British Broadcasting Corporation to send out an S.O.S. message. The message was successful.

RADIO INTERFERENCE

Electrical interference with wireless ception has become one of tlio most pressing problems in radio. Much that is attributed to static is often nothing more than interference caused by electrical apparatus in the vicinity of the set. Interference of all sorts was one of the principal subjects for international discussion at the great radio and telegraphic convention at Madrid recently. Frequently the hours at which interference occui's form a clue to its source. If, for example, you hear a loud, quickwhirring hum at times when neighbouring works are open, probably it is coming to you from some electric machine there. A very rapid whirr, heard more oil tho high wave-lengths than the low, and intermittently, might bo a medico-electric device being used by a doctor near you, as these "ultra-violet ray" machines operato in somewhat tho same way as an old spark wireless transmitter and send out waves usually between 2000 and 5000 metres.

Again, if there are neon lights or flashing advertising signs in your immediate vicinity, and your troubles begin only when darkness falls, one of these may bo tho culprit. In all-electric sets tho trouble often comes along tho power mains; sometimes it is picked up by the listener's aerial from quite a different source. Not long ago there was a case in which loud and rapid noises in a set were found to bo due to a thermostatically controlled incubator in the ljouso next door. .

It is for cases like this >.that. tho portable set is useful for detection purposes by moving it from place to place and using its directional aerial. Where electric motors are at fault, experience shows that this interference rarely travels beyond about 200 yards, and generally it becomes inaudible at 50 yards. Ilardly any form of electrical interference in fact travels much more than 200 or 300 yards. Already the English postal authorities have discussed this interference problem with manufacturers of apparatus capable of causing trouble, and a good many of the manufacturers have willingly modified their designs to eliminate as much of it as possible.

ON ALL WAVE-LENGTHS

" A wireless set for the car," says a headline. We understand that this offers tho motorist every facility for picking up pedestrians.

A set takes practically tho same amount of current when a programme is being received as when simply tuned to tho station and switched on.

The licence fee payable by tho owner of a receiving set in Italy lias been increased by two shillings a year. The increase will be allocated to a special fund for subsidising theatre productions of operas and other performances.

An organ—the finest that money can buy—is being built for installation in the British Broadcasting Corporation's luxury concert hall early next year. The organ is to be of the four-manual concert type with more than a hundred stops.
