Trans-Pacific Tests

T HE near approach of the Trans-Pacific radio tests directs attention to their importance to the wireless amateurs of .Australia. For some considerable time past a large number of enthusiastic experimenters all over .Australia have been hard at work building apparatus and completing arrangements in order that the best possible results may be achieved. It cannot be too strongly emphasised that these tests have a national as well as a world-wide interest. Therefore, it behoves all who have the progress of radio at heart to do all that lies in their power towards ensuring a large measure of success being recorded to the credit of .Australian experimenters. It can safely be assumed that those engaged in the actual task of attemptjng to receive the.messages transmitted by the .Amer ican amateurs will spare no effort to accomplish the aim they have in view. We trust that those not taking part in the tests will co-operate loyally with them to the rxtent of closing down their stations at the actual times at which it is calculated the messages will reach .Australia. lt is only a small sacrifice they are being asked to make, but non-compliance therewith will certainly have a very detrimental effect on the efforts of those who arc out to ,vin new distinctions for .Australian radio experimenters. There are some thousands of holders of receiving licensefl in the Commonwealth, and it naturally follows that each and every one is anxious to employ all his spare time in listening in to the signals, music' and speech which, to a more or less extent, fills the air every night. It is these enthusiasts who are asked to call a halt while the tests are on in order that a clear field may be · allowed those who are seeking to establish a new long-distance record for low-power reception. The forthcoming test is easily the most important event that has yet engaged the attention of amateurs in .Australia. A wide appeal was made for entrants, and while the results, numerically comprise only a small percentage of those holding licenses, the standard . of the competitors is exceptionally high. This only emphasises the necessity of non-competitors allowing them a clear field. There is no means of ensuring this other than by appealing to the honour of 1those indirectly concerned in the success of amateur experimentation. "-~ ' We feel that once this fact is realisecl everv radio experimenter who possesses a valve rece'rving ;et will fall into line with · the wish of th Trans-Pacific 'l'est Committee and suspend his activities during the currency of the test. By doing so he will be acting in strict conformity with the high moral standard which has characterised the doings of radio experimenters iu .Australia, and incidentally rendering a distinct service to the cause of radio research.

Growth of Radio Clubs

THE grnclual formation of radio clubs throughout .Australia is a healthy sign. Less than twelve months ago the number in existence was considerably less than it is to-day, and almost every week we hear of new ones being formed. As might be expected, the growth has been much greater in and around the capital cities than in the country, but there is no reason ,Yhy the country districts of the various States should not have a large number of clubs, consistent with area and population, in the very near future. It must be obvious to anyone who cares to give the matter a moments consideration that the clubs are reallv stepping stones on which the great science of radio will rise to the same dominant position in .Australia that it occupies in America and England. That the public here are not yet educated to the valne and possibilities of wireless communication is not at all surprising. The average p erson regards radio as a subject far too complicated for his untechnical mind, and even when it is demonstrated that the science is simplicity itself to a person of ordinary intelligence he still remains more or less unconvinced. It is in cases like this that radio clubs are able to render valuable service. 'l'hc educational influence of a few lectures and demonstrations is beyond question, and the formation of a radio club: in any district is certain to arouse the interest of mai1y who would otherwise remain indifferent to the march of this truly wonderful science. For this reason, if no other, the growth of clubs is to be encouraged, and enthusiasts in country centres, no matter how small they may be numerically, should band themselves together for the advancement of their hobbv. The outback districts offer every facility for exp"erimentation, and a practical demonstration of transmitting and receiving messages between different towns will do more to arouse public interest than the most eloquent word picture of the possibilities of radio communication which it is possib'Je to pa.int. We hope to hear of the inauguration of many country radio clubs in the near future, and those who undertake to form them can rest aHsured that the work thev are doing will stand as a monurnent to their faith and ~nterprise long after radio has overstepped the limits which bound its horizon to-day.

P.52 - Wentworth Club's Successful Effort

Radio Entertainment. Wentworth Club's Successful Effort. Large and Appreciative Audience.

The members of the Wentworth Radio Club, which is presided over by Mr. Spencer Nolan, have every reason to feel elated at the success which attended their demonstration of wireless music at the Club rooms, Rose Bay, on the night of April 18. The committee went to considerable trouble to ensure success, and the whole-hearted appreciation of the large audience must have convinced them that the effort was well worth while. The first broadcast items to be picked up came from Mr. F. Basil-Cooke's up-to-date station at Clifton Gardens. Punctually at 7.30 p.m. Mr. Cooke commenced his experimental transmission, and for just on an hour the audience in the Club room at Rose Bay, as well as a large number who had gathered on the lawn outside, were delighted and entertained with the vocal and instrumental items which came in loud and clear.
