It has two major objects in addition to the worthy one dealt with at greater length in the announcement; the production of a standard circuit to relieve the pressure on design engineers. The first additional object is to provide suitable editorial matter, which is a great difficulty in these times of shortage of manpower. Technical radio has a most important role in the war effort and "Australasian Radio World" has its place in technical radio, yet we agree with manpower authorities that its publication should be carried on with as little drain on the manpower supply as is reasonable. Hence, if some radio enthusiasts can devote their leisure to indulging in a little journalism, it is going to be an indirect assistance to the war effort. The second additional object is to give us some guidance as to the prospects of securing the services of a suitable technical editor for a vast expansion programme which is ready to come into action immediately victory has been accomplished. The prospects of post-war radio are truly vast, and for our part we have laid our plans to maintain a position right out on the top of technical radio developments. Our choice of a suitable person for the congenial position of technical editor will be largely governed by the merit of technical articles contributed between now and then. - A. G. HULL.
