Notwithstanding the difficult conditions which must prevail on account of the incessant bombings, the radio press is still performing its work of national importance by disseminating technical information. In London the good old "Wireless World" carries on in grand style, strongly supported by the leading advertisers. In their latest issue we notice nearly all the famous brand names amongst the twenty-two pages of advertising. Fortunately, our position in Australia is infinitely safer than in Britain, although our radio business has its trading difficulties. It is encouraging to notice that these difficulties are being faced in true Digger spirit and with a long-range outlook to the wide span of years which lies beyond our immediate task of dealing with the present disturbers of the peace. In the meantime, we radio men will need to show the keenest initiative to keep our million and a half radio receivers in good operating condition.
