Rotating mirror drums and similar devices, which must be run accurately in step, can hardly be set up in the home workshop'. 'Up to the present time most amateur constructors have been deterred from embarking on the reception of television by purely mechanical difficulties. Here is another report, this time from our technical contemporary, The Wireless World, who describe the system as a 'most promising method of reception', and hail it as ideal for the home-constructor. He, and the company he represents, must share the laurels that have been scattered forth.

At this point I must in all fairness bring before the radio curtain Mr T Price of the Ediswan Valve Research Department, who has collaborated with us very closely in our tests, and to whom is due the Special Ediswan T tube used in the viewer. 'The secret of good reception of television has now been discovered, but television has yet several years to go before it will have reached the same stage of perfection as radio'.Īs can be seen, Garry Allighan, who moves closer in radio circles than most radio critics and press correspondents, shares with us the firm conviction that the future success of television rests with the cathode ray method of reception, and he makes no bones about appraising the demonstration of it that he was given. It is to the amateur experimenter that the country should look for the ultimate triumph of television, as it was the amateur experimenters who were responsible for modern practical radio'. I have already quoted from Garry Allighan's report of a demonstration of the system in the Evening Standard, but for the sake of those who did not see it, here is a brief excerpt in which he describes it as bringing for the first time 'practical television reception within reach of every amateur experimenter in the country. Now let us turn to what has been said openly about our Cathode Ray Television viewer. I have already referred to it in these columns, and a complete answer for the benefit of those who may have heard it (it has not been published!) is being made in a following issue by our radio consultant, Dr J H T Roberts.Īpart from that piece of information I do not intend to devote further space to the subject it is in itself too trivial a matter, but to the uninitiated, and untechnical mind, such as whence it sprung, it might give rise to completely erroneous presumptions. The criticism has come from one quarter, and it has been carried out by behind-the-back whisperings of the vaguest character. It was the first thing of its kind ever done, and the detailed description of an easy-to-build non-mechanical television receiving outfit was a step forward in radio that could hardly go unnoticed, or for that matter uncriticised. I suppose it was inevitable that the publication of details of the Cathode Ray Television Viewer should attract a great deal of attention, not only of readers but of the various sections of the lay and technical press. This article deals with reports that have been published and with letters received from readers. Our Cathode Ray Television scheme was such a big step forward in the science of television that it has attracted great attention from radio firms and the press.
