Si—It may be of interest to some of your readers who are short-wa ent ts to have further express Ble sions of opinion upon the distortion fud interference which at the present time Is occurring locally. From own experience with a very modern Superhet receiver, the main causes of the trouble may' be classified under {iro heads, viz 1 Bey osa "or ether Code transmitting stati apparatus regard 10 the former, there 1 Jconcerete evidence that certain. Local fede transmitting stations are. very much to blame for interference with reception of the International tuning bands, due to their apparatus not be-{ng kept.in correct alignment with their particular wave lengths, with the result that their code transmission "spreads" over the shortwave bands. 'AE the present time Ulus is strongly in fevidenee on the 18 metre band with {the exception of Sundays!)—and eompletely blanks out Berlin and Daven-fry. It is to be Noped that, thbse odic stations concerned will at least take steps to Keep the international {tuning bands clear of interference on their part during "the forthcoming [Coronation " brondeasts, although naturally one would prefer a more permanent remedy. This particular Interference is closely associated with code transmitting station situate in Avenue Road, but this reference. no. way includes the US. Marines station from which no interference Is fexperieneed personally.
The second trouble mentioned has Jaeveloped during the past few weeks Jand. commences. each evening with liting-up time, "This causes. very eud and continuous hum in the reeiver over the whole of the shortwave. bands, and makes reception almost "impossible, "No doubt. the Power Company, who it is understood how has "this cause of interference finder investigation, wilt soon Toeate the faulty apparatus.
If these two main causes of bad shortwave reception could be corrected in time, one could reasonably hope to" get the "Coronation broad Jeasis. "Perhaps those parties at fault would do their bit to assist tu this direction?
