Mr DAVIDSON - Some little time ago, shortly after the commencement of operation of station ABC - Channel 2 - the national station in Brisbane - I heard some complaints, which I could not describe as general or amounting to widespread dissatisfaction, that on certain television sets the reception of pictures transmitted from that station was not as good as the reception of those transmitted by the commercial stations. I therefore arranged for the Australian Broadcasting Control Board, which is responsible for investigating anything like this, to have a look at the position, and I can inform the honorable member for Lilley that the fault does not lie with the transmitter. The transmitter measures up to all the required standards laid down by the Australian Broadcasting Control Board. The board discovered that in some types of sets - I do not know what the types are - a herringbone pattern is set up, particularly towards the top of the picture. This arises from the greater strength, rather than from any lack of strength, of the national station. In other words, the greater signal strength of that station, in comparison with the commercial stations - which commenced operations earlier and to the strength of which receiving sets had been more or less attuned - causes this condition. I repeat that the condition arises only with certain types of sets, and the Australian Broadcasting Control Board has been in touch with the manufacturers concerned, suggesting that some minor alteration should be made which would relieve the situation. As the honorable member has said, it is possible to obtain a relatively small gadget called an attenuater, which can be fitted to a set and which will remedy the trouble. I can assure the honorable member for Lilley that the matter has been looked at. If he has some friends who are having this difficulty, I suggest that a talk with a competent television engineer will enable them to solve the problem.
