Printed by Bridge Printery Pty. Ltd., 117 Reservoir Street, Sydney, N.S.W., for the proprietor of the "Australasian Radio World," 117 Reservoir St., Sydney (Footnote P.52) P.03 - Our Front Cover OUR FRONT COVER Over 7,000 people visited Radio Hall at David Jones' George Street Store during the "Romance of Radio" Exhibition held last month. Prominent among the leading radio manufacturers exhibiting was Standard Telephones and Cables Pty. Ltd., with the particularly attractive stand shown on this month's front cover. The display featured a working display of actual radio component construction. Many visitors stopped to watch the deft fingers of the girl operating the coil winding machine. Other portions of the S.T.C. display, not included in our picture, featured o bridal effect, with the suggestion of an S.T.C. radio receiver as a wedding present. P.04 - Editorial Notes PERSONAL This issue should really be a special birthday issue, as it is just five years since that sunny day in May of 1936 when the first issue of the "Australasian Radio World" appeared. Instead of putting our quota of paper to the glorification of the success which has been achieved, we offer something a lot more practical. It takes the shape of a special section for servicemen. We feel, however, that the occasion does call for a little praise for those who have guided the destiny of the paper. Tribute must be paid to the policy which has been so steadfastly maintained. Suggestions for obtaining wider circulation by the introduction of extraneous articles of a "popular" nature have been repeatedly declined. Success is the practical proof that the radio trade and those interested in technical radio are pleased to maintain a magazine devoted exclusively to their interests. Owing to this somewhat restricted editorial policy, it has taken time to attain our present circulation, but we are now quite confident that we have a complete coverage of radio enthusiasts, set-builders, factory technicians, country dealers and in fact all those interested in the technical side of radio throughout the whole of Australasia. We also find that our Short-wave Section has a strong following among keen listeners who want authentic information. The number of copies being posted to various consulates and to foreign countries is indicative of the good work done by the original short-wave editor, Alan Graham, who is now abroad with the A.I.F., and our present short-wave editor, L. J. Keast. It is interesting to note that in strong contrast to the advanced technical features in this issue, we also offer on article on a two-valve headphone set which is based on the design of a similar receiver which was featured in our original issue of May, 1936.

J. Keast Shortwave Review conducted by L. J. Keast NOTES FROM MY DIARY Recruits Respond With this issue comes my thirteenth attempt to keep up interest in short waves for those who have already explored this fascinating avenue and an endeavour to get others to use that portion of their set that permits them, as Sir Ernest Fisk said when opening "The Romance of Radio Exhibition," "to open up that magic door which brings the world before you." The growing number of reporters, the new members of the All-Wave All-World DX Club and the record number of new subscribers suggest that the policy has been approved. The lecturettes I gave at the Royal Empire Agricultural Show and at "The Romance of Radio" Exhibition at David Jones attracted such crowds at all sessions that I am firmly convinced of the ever-increasing interest in overseas listening. Fully aware of the excellence of the modern receiver, these distant countries now feel they can claim the world as their audience, and the consequent international flavour of the programmes makes listening all the more enjoyable. This combination and the fact "long distance" per radio costs no more is undoubtedly one of the reasons for the converts. I was pleased at the two occasions referred to, to meet so many of our reporters. Quite a number I know only by name, but the general knowledge they had of overseas reception fully confirmed the impression I had gained from their exhaustive reports. Schedules Go Overboard The American broadcasting stations, ever mindful of the interest in topical events, throw convention to the winds and schedules and programmes are sacrificed at a moment's notice when a sudden change in world affairs takes place. An instance of this was the German invasion of Yugoslavia. WRCA, 9670kc, 31.02m, continued long after 4 p.m., their customary hour for closing. Unfortunately, we were unable to benefit from the subject matter, as KGEI, opening at 4 p.m. as usual on exactly the same frequency, figuring their source of information was just as reliable, did their best. Result: Bedlam and, strangely enough, the New York transmitter, if anything was a trifle the louder. WNBI, 1,890kc, 25.23m., who usually close at 4 p.m. stayed on another hour or so, and the Columbia Broadcasting System outlet in Philadelphia, WCAB, 49.50m, was heard till 7 p.m. And Still They Come All India Radio are being heard at terrific strength on 7290ke, 41.15m, from about 10.30 p.m. They may open earlier, but at 10.45 announce in English, "This is Delhi calling. We are also on VUD-4, 25.36m, and VUD-2, 85.84m." They appear to leave the air on 41.15m. at 1.30 after announcement in Hindustani. All attempts to land them on 85.84m failed. A Familiar Voice When checking up mid-day reception on April 25, I happened to be tuned to London just as George Ivan Smith spoke in Radio Newsreel. He referred to several towns he had visited and gave a splendid picture of Lisbon with its now more than ever cosmopolitan population. He mentioned the beauties of the English countryside and paid a great tribute to the courage of the Britishers whose one and only thought was, "There's a job to be done." Antics on 13 I think we can shortly expect some antics from the 13 and 16-metre bands. This is just about the time when one night they will behave splendidly, while on the next their poor showing would almost suggest trouble with the set on that band. Reaching the height of their idiosyncrasy about the middle of May, they will most likely refuse to be friendly until August, when from then on, they will show an eagerness to come into the field or, rather, the air again. Have noticed on several occasions during the last week, the 19-metre band has been poor between 9 and 10.30 p.m. In fact, on two nights in succession it was impossible to hear anything. At 1 p.m. signals were back to normal. Welcome Welcome to Mr. John S. Beatty, of Kavieng, T.N.G., as a member of the All-Wave All-World DX Club. Mr. Beatty sends a list of loggings which shows the variation in signal strengths in his location compared with Sydney. Listeners are reminded of the changes in Daventry schedules and frequencies, a good many of which will probably have been noticed before this issue arrives. Under "This Months Loggings" I have shown most of the changes. Brief Mention Listeners are reminded that some of the United States of America adopt Daylight Saving as from April 27, so schedules shown under Loggings may be out a trifle. The new A.B.C. transmitter, VLR-8, 25.51 m, appears to be generally approved by reporters, affording a much better signal, particularly in Queensland. However, there are times when 1 wish they were a little farther away from GSD. Although the remarks heard may not be those of the oldest inhabitant, 1 am sure we all welcome back to the air, OFE and OFD, Helsinki, Finland. They are both being heard daily in the early mornings and mid-afternoons. Running over the 25-metre band on March 31 heard Radio Saigon open up at 10 a.m. All talk was in French. VLQ-3, 15,310kc, 19.59m, is being used in place of VLQ-7 for Transmission X. to North America. If you doubt this statement, sit up till 3.55 a.m., when they are due to commence. MTCY, Hsinking, 9540kc, 31.43m, opens at 7 a.m. with news in English. WGEO, Schenectady, 9530kc, 31.48m, is now being heard well, and the session being continued till 3 p.m. meets with general approbation. Looks as though XMHA, Shanghai, have forsaken 25.24m for their old love, 25.31m. Signal is splendid, and news at 9 p.m. by Carol Olcott can be followed with ease, but when VLQ-2 later on appears things are NOT so good. That station heard after 2GB closes down is JOAK-2 in Tokyo, one of the broadcast transmitters of Japan on exactly the same wavelength as 2GB, viz.. 345m. The peculiar language round about 8 a.m. on 31.51 m is the Paris station, "Y," using Arabic. RW-15. Khabarovsk, on 31.36m, appears to have left the air of an evening, with the result our old friend, KZRM, Manila, "The Nation's Station" can again be enjoyed. Dr. Gaden tells me my favourite musical programme from London, "Hi-Gang," is to finish on May 18. Perhaps that signals the oft talked-of visit to Australia of Bebe Daniels and Ben Lyons. Roy Hallett tells me the Columbia Broadcasting System are building on Long Island, New York State, two new transmitters of 50 k.w. power, due to go on the air about September.

Send in reports as fast as you hear anything unusual; also items for "Help Wanted." The Fall of Greece THE FALL OF GREECE Naturally anxious to hear the latest news from Greece, I tuned to SVM on 30.196 metres at 5.35 a.m. on Thursday, April 24. When the station did not open as is customary at 5.40, I was uneasy as to its fate. However, at 5.48 I noticed a carrier- Wave and, sure enough, Athens was there. But it was not our usual announcer and the news was not the cheerful reference to victorious advances we had become accustomed to. No, it was the statement that the Proclamation of King George I. would be read. It was, and the emotion of the reader could be distinctly noticed. After it was read, I thought for a while and then tried to picture this poor man in front of a microphone not knowing who would be his audience, but probably hoping the world would hear his sad story. Regrettable as the news was, I felt pleased I knew at least one person was listening. On Monday, April 2.8, SV M, Athens, was not on the air. Will this splendid transmitter be used by the Germans as they have done in other conquered territories? I feel glad now that I was one of the audience at the final curtain.

P.44 - Short-wave Section - New Stations NE W ST A TI O NS Azores: CT7AJ Ponta nelnada, 4002kc, 75.00m: This is the station I referred to last month. Mr. Taylor, of Mosmon, is positive he heard this station. Here is what he says, "I don't bla me you for finding it a bit hard to believe the reception of CT2AJ, but, nevertheless, it is true. Here is how it ca me about. I was listening around 75 metres one night at 10.45 when I heard a station on approxi mately 75 metres. I listened till 1 o'clock and then I heard "Ponto Delgada, Sao Miguel Azores." I then looked un some American magazines I have and found CT2AJ on 74.95 metres, to be locatin Azores. Also the time coincided with the schedule. It has also been heard now et 8 a.m. At both times it is R5." Going through my papers, I find this station is shown and frequency and wavelength. Azores, or Western Isis, Portuguese group in mid-Atlantic, 1500 S. W. of Ireland, and 1700 miles E. of Nova Scotia; area 922 sq. miles; population, 254,000; capital, Aupra, on Terceira I. Ponta Delgada, on Sao Miguel, is the largest town in the Isles, with a population of 16,179. India: VUD-2, Delhi (7290kc, 41.15 m): This is not actually o NE W station, but has only been noticed durino the last month as operative. Opens at 9.30 p.m. with some program me as VUD-4, 25.36m. Closes at 1.30. Heard announcing at 10.45, they were on 85.84m and 25.36m. Latter frequency is well known to us, but so far have not heard them on theformer. The 41.15 signal is probably as loud as any on the air. Another of the Secret Stations has shown up. Location is unknown, but the language used is, as far as I can make out, "Sender Europaeischer Rundfunk" ("European Redo Station"). Stationopens at 7 a.m, sharp in German, and for about ten minutes gives a talk in German. After a brief pause, someti mes talks in French. Announce they are on the air at 9 p.m., 1 p.m., midnight and 2 a.m. It is of course the 9 p.m. session I heard (7 a.m. Sydney), on 9.66 mc, 31.96m. Careful tuning is required, although strength is good, as 2R0-9, on 31.02, is on one side, and WCBX, 31.09, on the other.
