RADIO INTERFERENCE.

CAUSES AND REMEDIES. ELECTRICAL FAULTS RESPONSIBLE Radio interference from electric-power mains has become sufficiently serious to lead tho Public Works Department to circularise power boards, seeking their cooperation in eliminating the trouble where possible. At present there are no regulations governing the matter. Irregularities in electrical circuits and apparatus are among the causes of interference. Tramways also provide their quota, although tho trouble in this case is not always as serious as may be imagined. It is stated that the lighting circuit in a tramcar will cause more interference than the traction circuits, the smaller current forming a spark, whereas tho traction current forms an arc. Most interference troubles aro due to continuous or intermittent sparking at contacts, either intentionally, as in the case of motors, switches or flashing signs, or unintentionally, as in the case of faulty or partially broken conductors. One of tho most prolific sources is tho average house lighting circuit, because of the comparative lack of attention it receives. The use of a sensitive alternating current operated receiver in a house will very quickly prove the existence of faulty switches, refrigerator, or vacuum cleaning motors or other appliances. A likely source of trouble is a loose contact, in a plug connecting apparatus to the circuit, or in a fuse which has not been tightly set' up in position. Flexible cords to radiators, portable lights, irons, vacuum cleaners, and so forth, will also cause trouble if they havo reached tho stage when' some or all of tho internal conductors are broken, or when the insulating material has become sufficiently damaged to allow leakages between wires, or from one wire to earth. Tho best way of successfully avoiding the trouble is to remove the source, or, if that is not possible, to provide suitable filtering apparatus at the point at which tho interference originates, for sparks *ict in much the samo way as the old type of spark transmitter, and radiate interfering signals, but of indetcrminato wave length.

8.8.C. " INQUISITION."

QUESTIONNAIRE FIASCO. DETAILS OF FAMILY LIFE. Only 5000 replies have been received by tho London School of Economics to their questionnaire) on family life arranged in conjunction with the British Broadcasting Corporation. The number of forms sent out was 48,340. It remains to be seen whether this figure will bo considered as justifying the considerable expense to which the 8.8.C. has been put in printing and sending out the questionnaire forms ,in responso to inquiries, even if a further 5000 replies which, it is stated, the London School of Economics expects, should materialise. The much-criticised questionnaire was announced in January in connection with a series of broadcast talks by Sir William Boveridge, Director of the School, on "Changes in Family Life." Listeners were asked to apply for a form in which were set out a number of questions relating to the most intimate details of their family life, such as "Where did you first meet your wife?" and "What was your grandfather's occupation ?" The replies were to be tabulated at the London School of Economics, and from thorn it was hoped that there would be obtained valuable "information in connection with the social sciencos." Members of the school were asked to co-oporate. Tho total nnmbor of questionnaires sent out on request was 48,340. The latest figure obtainable of wireless sets in constant use in England is 3,000,000. So the responso does not appear to havo beon encouraging.

SUNDAY PROGRAMMES. POLICY OF THE BOARD. What appears to be a new policy governing broadcasting programmes on Sunday afternoons is indicated in a lettor recently received by the Mayor of Christchurch, Mr. D. G. Sullivan, from the New Zealand Broadcasting Board. Tlie letter, which was in reply to representations that a servico in connection with tho Grand Lodge of Druids should bo broadcast, stated that, owing to numerous complaints received from listeners at interruptions in the normal Sunday afternoon gramophone rentals, the board had decided that it would be inadvisable to broadcast tho service. Many radio licensees contended that tho Sunday afternoon gramophone programme was tho only one that they had an opportunity of enjoying, and that only for outside broadcasts of exceptional importance should tho programme bo intercfered with.
