\V Itj-iijXj.'i ijrTUis, May 31. "Better radio reception through. the :elimination of the heterodyne whistle or "flutt'er" so often heard in. the - background, is likely to result from changes in \ra.olength cliaunels for ali New Zealand stations which wili come into ejfect from September I this year. The changes were announced tonight Lii a.'joint 'slateiiient issued by the Minister in Gharge of Broadcasting, the. Hon. F. . Jones, and the PostmasterGeneral, -the Hon. F. Haekett. SirnuitanCousiy an announcement is being made in Austrulia regarding changed wavelengths there. -The statemeat also- reveais chahges 'in the call-signs of some New Zealand stations and aJso those which will be "used by nqw stations which have yet to ' begin broadcasting. The wavelength of 2ZA, Palmerston North, will be changed from 1400 Hc/s. c.0 040 lvc/s. t • The plans now under way for the tncrease in the power of present trausuutters and the establishment of new stations, said the Ministers, invoiveu eertain alternations- -which were being uiade with an eye to the elimination of nterference from Australian stations. JompJaints were often reeeived, , ;.jspecially from country listeners. . riiev found It difficult on occasions to . receive New Zealand stations owing to the heterodyne ivliistie caused by the proximitv of Australian stations to those to which they were tuning in New Zealgnd. This caused u 1'fiuttei " in the background, resulting In the distortion of signals and . some-" times rendered reception impossibie. ".The . total wavelength chanuels aya'ilable for jqint use of Australian and. New Zealand stations," said tlie Statement, "are not sufficient to aliow eaeh station to liave an exclusive channel, so -that in some cases stations in both countries are operated on the, samc wavelength. ' ', Altliough the inerease in power of New Zealand stations would hclp to reduce this trouble, it was explained, a miuilier of Australian stations are also being given increased transmitting t'Ower. . (So New Zealand took the opportunity of conferring with the Australian administration with the result that a frequencv allotation was worked out to ensure tlie minimum amouut of intcrference in futurc. Other changes will enable the morc important stations to iniprove their coverage and to make better use of the new aerial systems whicli are to be adopted. Altliough tlie stations afi'ected will be tuned .in at slightlv different places on t the receiver (lials, tlie beneflt to li.steners,.it is t'ell-, .will oH'set any initial •iuctfttvenience.' resulting', especiaUy iij casos ivhefe (Eals are marked with the eail-signti of • ktations.
