All persons engaged in repairing or servicing radio sets who have not applied for a licence should do so before July 19. Applications should be addressed to the State Deputy Director of the Department of War Organisation of Industry at your capital city. It should be noted that those who do radio work in their spare time, or are capable of doing so, are invited to register and will be officially encouraged to carry on with work of this kind. At the moment of writing the full details of the scheme, and especially in regard to its control of radio component parts, have not been revealed, but it is evident that radio servicing is at last to receive the attention it warrants. We strongly advise all of our readers to make a point of sending in their names for registration immediately, as failure to register now may have far-reaching effects in the future.
