## P.03 - Editorial Notes

Editorial
Every now and then there is a tendency to get an impression that radio development has reached its climax, that every avenue of application has now been explored. Just in case you feel that way we would like to tell you about a book recently received from overseas. It deals with some new ideas about the use of ultra high-frequency radiations. It mentions such things as special valves with positive potentials on the grids and negative potentials on the plates, just to get the electrons mixed up so that the valves will oscillate without regeneration. Like a fairy story read the chapters about radio transmission from lenses made of ebonite, instead of aerials. Further details cannot be revealed at the moment, but you can take it for granted that when peace returns the wartime research will be found to have paved the way for radio development on a scale never before imagined.

Editorial
You may be a good radio engineer, but can you prove it? Recently there has been a strong call for radio engineers to serve their country in connection with the construction and maintenance of radio location equipment. Wonderful scope is offered, together with quite good pay and excellent conditions, apart from the patriotic appeal. Many of our readers have responded and are now on the job, but one or two have found to their amazement that they have not been able to prove their ability. Although thoroughly capable on the practical side they have not possessed any university degrees or diplomas. When faced with a qualifying examination they have not been able to fully reveal their ability, and wish that they had taken the precaution of associating themselves with an organisation of some kind, such as a radio college, technical school or that worthy organisation, the Institution of Radio Engineers.

Editorial
Owing to difficult trading conditions - most radio lines being easier to sell than to buy - there is a falling off in advertising, thus allowing more space to be devoted to reading matter. Scarcity of paper, however, tends to offset this gain, and so we find ourselves this month with an issue which contains only a small number of pages, a few scattered advertisements, but a full complement of technical matter which will give some idea of the way in which "Australasian Radio World" will face up to changed conditions. Space being so much at a premium, we are unable to go over the fundamentals thoroughly in each issue, but we do keep a stock of back numbers so that these may be referred to for such matters. We find that these back numbers are in keen demand, and the success of our recent special offer of a set of a dozen for 5/- prompts us to make another special offer. This time we are prepared to supply, post free, a complete set of the 1941 issues to every reader taking out a subscription for 1942. Only a limited number of sets are available and so an early application is essential.

Editorial
At the moment of writing, the future, to put it mildly, is obscure. Nobody can possibly imagine that the prospects are rosy, and so I have been doubly pleased to find that my readers have expressed their confidence in me so positively by renewing subscriptions. At the moment our list of direct subscribers is the highest it has ever been in the history of the publication. New subscriptions have come along steadily during the past month and quite a considerable proportion of these have taken advantage of the special offer of £1 for two years! Such expressions of confidence have spurred me to make every effort to safeguard the future. Precautions have been taken, and even a direct hit on the office by a 500-lb. bomb will not stop the old "Radio World" from coming out on time every month. But I feel that it is up to me to do my bit for the national effort, and so I am at present engaged on a matter directly connected with the war effort. This means the temporary suspension of the laboratory service, and may mean delays in the queries service, but I am sure that readers will appreciate the difficulties of the moment. V for Victory! A. G. HULL.

Our photograph shows Mr. Ron Bell, managing director of R.C.S. Radio Pty. Ltd., at the mouth of a large concrete air-raid shelter which has been built at the R.C.S. factory. Mr. Bell has the interests of his employees at heart, and is also keen to make certain that there will be no interruption in the supply of R.C.S. components, which are used so extensively for both civil and defence requirements.

## P.03 - Editorial Notes

Editorial
Pioneers often hove a tough time of it before their work receives proper recognition. John Bristoe, author of our series of articles on signal tracers, might be considered a pioneer, and accordingly his articles hove not been accepted by all our readers. Quite a few hove their doubts about the value and efficiency of the signal tracer, and the subject is a fertile one for arguments. Frankly, we hove not hod much experience with them in our own laboratory, but there are two factors which influence us to put our backing behind Mr. Bristoe. Firstly, we know that Mr. Bristoe is a practical man, in charge of a radio deportment, handling hundreds of sets, and, secondly, we note that those who doubt the value of the signal tracer are mostly those who have not actually tried them in practice. They base their opinions on theoretical considerations, which ore not, to our way of thinking, sufficient in themselves in a case like this. To those in doubt we can only suggest that a little practical work with one or another of the signal tracer outfits will soon convince them that they are well worthwhile for those who hove a volume of servicing work to handle.

## P.03 - Editorial Notes

Editorial
It is abundantly clear that our Battery Circuit Contest is going to be remarkably successful. It has created considerable interest in many country towns and provided a topic for conversation in most factories, according to reports from our readers. Country dealers appreciate the value of the publicity angle of having their views published and, from our point of view, we don't begrudge them this free advertising, so long as it is all for a good cause. What better cause could you imagine than helping the country man to get better performance from his set? The candid expression of opinions by country men, who are on the spot obtaining practical experience, must be a big factor in assisting in this direction. From our own point of view, we are especially delighted, as we have in hand a stock of editorial matter which should make the next half-dozen issues of infinite interest to all country readers.
