This suggestion has been challenged by an entrant in our Utility Circuit Contest Mr. P. Stevens, of "Westdale," Fletchers Avenue, Bondi, who says, "Weak or distant stations, marred by static and fading are seldom patronized except by the DX enthusiasts, and the same thing applies to overseas short-wave stations. The thrill of listening to the "truth" on Tokyo or Berlin radio through a more or less dense cloud of interference will end together with the war, and as the continuous sideband fading on short-waves makes the tonal quality rather poor, receivers should be built for broadcast only." Chatting with factory set designers about this subject has shown that there are quite a few who readily agree with the opinion expressed by Mr. Stevens, and there seems to be quite a chance that the preference for dual-wavers will fade like it has for other "selling features" such as clock dials and push-button tuning. We have not been able to conduct a "Gallup Poll" on lines extensive enough to be considered representative, but it is fairly obvious that not five per cent of the listening time of the average dual-wave receiver is spent on the short-wave band. Yet on the other hand we read of thousands upon thousands of pounds being spent on the erection of bigger and still bigger short-wave transmitters, and doubtless they expect to have vast audiences. - A.
