Heterodyne Interference Eliminated
Between N.Z. and Australian Stations AS the result of complaints made regarding the interference with 2YA and 3YA, caused through transmissions by Australian stations, Mr. G. McNamara, the Secretary of the Post and Telegraph Department, advised the Broadcasting Company that the trouble has been rectified by restoring 5C%& to its correct frequency of 730 kilocycles, from which it ha deviated, and by moving 3BO to 970 kilocycles. Check measurements of the frequencies used by Australian stations are stated to be made at regular intervals, but should any further interference be noticed in New Zealand, the Commonwealth authorities would appreciate advice to that effect. Mr. McNamara adds: ‘‘I am informed also that measurements of Z2YA made at Melbourne with a multivibrator standard frequency unit showed 2YA to be right on its allocated frequency of 720 kilocycles."’ _
