EDITORIAL.

This issue and the last one must surely rank as two of the weakest issues we have ever published. We admit it quite frankly. Instead of wasting time explaining the whys and wherefores of the many factors which have conspired to bring about such a sad state of affairs we want to again reassure readers that there are brighter issues "just around the corner." Our postwar plan for improvement is still to open, but it won’t be long now. Already the features of the plan have been brought into alignment, but there are still one or two points to be straightened out. First and foremost, we need an editorial representative in Sydney. For preference the representative should be an enthusiastic young fellow, with at least a fair idea of technical radio and the ability to build up a set or two, who will keep in touch with the Sydney radio trade, find out all the new components that are being prepared for release, and generally make sure that we don’t miss any of the Sydney goings-on because of our decentralisation plan. For a start it might be possible for the job to be part time, or even done by someone who spends lunchtime in town, but it should soon develop into a full-time job with the establishment of a city office when such luxuries again become available. Next thing we want is a larger team of contributors of technical articles. We never seem to get enough of the type which are suitable. If you have any ideas or propositions to help us in these matters or any other suggestions, you will find that we are especially receptive at this moment. — A. G. HULL

P.29 - Technical - Short-Wave Listening
Short-Wave Listening There are SW L’s with a flair for meticulous and careful observation of amateur transmissions, and from whom detailed reports are welcomed by the Ham worth his salt. It’s a safe bet that when an SWL with plenty of experience, like Ted Buchester, Q’ld, puts his pen to paper, something of interest results. O f my remarks recently about V K ’s who scorn SWL reports, he writes at length: "I can recall sending a report to a VK7, a most helpful bit of gen. by the way, and he told me to let it be known he did not QSL to listeners. He was playing recordings (now I am aware how you chaps hated these guys), and the modulation was 100 p.c. and honestly 5 and 9. If I hear a 'Ham’ calling C.Q., and his sig. is, say, R8 or ?■ at this location and he eventually has a contact, and the other man gives him a poor report, and the said ’Ham’ talks of dragging the antenna down or something like that, it annoys me not to be able to give him a buzz. I do the next best thing and drop him a line, not asking for a card, but a reply, and I have not missed on that yet. I am using an ordinary 6-tube Super, 1 -stage R.F., and have tried a few antennas, but am doing quite well with one of those V types as in ARRL Handbook, 1945. Have not concentrated on normal short-wave stations, but like, the 'Hams’ best as yet. I have only two verifications from overseas amateurs, namely W llC Y and XE2FC. These were pre-war. My oldest veris are from KSL and KGU, 1935, and I can recall three very outstanding signals heard here prewar, i.e., W 6CQS, W 5B K Y and K 6BNR. I seem to hear more V K 3’s and 5’s here. V K 3TW puts in a fine signal most consistently. PK6AW comes through here quite well, also a few South Americans, but G ’s are very scarce. I am learning C.W. now, and am definitely going on the air in the near future. Am just out of the R.A.A.F. (served by ''sentence” of 5 years 4 months) and me and quite a few 'Hams’ in same. It appeared the 'Hams’ and the Air Force did not hit it too well re ideas, but the 'Ham’ won in the end. Would like very much to purchase a Call Book.” Mr. Buchester’s log of amateur stations for August last is shown here for the benefit of overseas readers. Re the V K call book: It is understood that 2/6 to the P.M .G.’s Dept., Wireless Branch, Treasury Gardens, Melbourne, will bring the complete list to the present period. — D.B.K.

P.30 - Shortwave Review - Notes from My Dairy
Shortwave Review. Conducted by L. J. Keast NOTES FROM MY DIARY 1947 . . . W H A T HAVE YO U? First of all let me say my good wishes for the Festive Season were frozen out of December issue on account of pressure on space, but I hasten now to say "thank you very much" to all those fine reporters who, during the year, have rushed along the results of their loggings, thus enabling those indulging in this great hobby of D Xing to reap the benefit of their finds. And amongst the reporters referred to I include and thank Miss Sanderson for her splendid contributions. This lady has shown that she can "bat" with the rest and her carefully and correctly typed lists are a treat to read. But there must be many readers of these columns who hear changes of frequencies or schedules that may be given at the very time the Gilletts, Cushens, Gadens, Edels, Suffolks, Whitings, Halletts, Legges, Boords, Sandersons and the many other regulars are not on that particular station, and I would like those readers to send in some reports. Please do not hesitate. . . don’t be frightened. . . SEND THEM IN. Let this be one of the things 1947 has for us. What the technical side has I do not know, but I’ll wager our good friends Mr. Hull and Don Knock will be watching. However, even at the risk of being considered "catty,” I must tell our friends in the other states, we have the first television receiving set in Australia on display in Sydney. W ell, here’s wishing all readers of these pages the very best and whatever you hope 1947 may have for you may it happen. W ITH THE BBC TW EN TYFOUR YEARS AGO Yes, it is just over 24 years since the first BBC programme went on the air. On November 14, 1922, British broadcasting under the control of the Broadcasting Committee began— the declaration of the polls in the General Election was the first broadcast-— and the initials BBC began to penetrate the national consciousness. On December 15, the British Broadcasting Company Limited was formally registered with a Board of Directors drawn from the General Electric Company, Marconi’s, the Radio Communication Company, Metropolitan Vickers, British ThomsonHouston, and Western Electric, and the late Lord Gainsford was appointed the first chairman. HERE’S HOPING The Bob Hope family increased 50 per cent recently with the adoption of William Francis (Kelly) Hope and Honora (Nora) Hope, both less than one year old, from the Cradle at Evanston, 111. The Hopes have two other Cradle babies— Linda, age 7, and Anchony, age 6. W ell, that’s a very fine gesture, and we wish them all the best of luck. KEEPING COUNTRY AFOOT Red Skelton says, "It’s the radio comedians that keep the nation on its feet— every time they tell an old joke, thousands of people get up and turn the radio off.” THE SIX PIPS The man who originated that famous feature of the BBC programmes, the six-pip time signal, has received the Gold Medal of the British Horological Institute. The medal is open to world competition. He is Mr. Frank HopeJones, a man who came from the North of England to London five years ago. The signal has been adopted by many foreign countries. The award seems not to have been made with undue haste, for the BBC time signal has been regularly used for over twenty years. It is, of course, an electrical device, but on one occasion years ago the apparatus was mislaid, and an engineer improvised the "pips” with a hammer and a piece of wire. No one noticed anything wrong. — "London Calling” SAYS W HO? Miss Sanderson, of Malvern, Victoria, writes: I have been hearing the AFRS station at Amoy. It was 8.15 p.m. and the programme was very easily copied, the noise level is very high, so together with morse it is very hard to hear what is going on at times. I have heard another Chinese station, XOPD, in the 31m. band, at a very good level, the freq. was 9.55 mcs. and the programme typically Chinese, and the time was 10 p.m. Call sign was given in English. 41 metres is improving in strength and some quite good signals are heard as early as p.m., when Hanoi on 7.26 mcs. or 41.32 m. gives news in English and a commentary, prior to this time the broadcast is in French. VUM and V U B2 are heard in English news and local news on the respective frequencies of 41.25 m. or 7.27 mcs and 41.44 m or 7.24 mcs. With regard to early morning listening, this has been very good. I have heard quite a number of stations from Europe and Allied countries. Captown No. 3 is heard at 6.30 a.m. in a programme of news and music at qu'ite a fair signal for this part of the band. Bulgaria, Brazil, in 31 m. and 30 m. with good signals, and Sweden heard on Sundays at 5 p.m. with its English lesson and later a church service at 8 p.m. I have recently heard from a DX-er in Sweden, and he has sent on two very interesting magazines which contain the broadcast and shortwave schedules. I have sent on some of our magazines (Radio) for his perusal. This young man is a student and writes very good English. I have had a verification from Radio Andorra, and CBFZ and schedules from Burma Broadcasting Service. These are very useful and I am very plased to receive them. I am still finding Universalite very handy, and have sent off a report to Mr. How,e and also to Mr. Boord. I trust that these gentlemen will find them of interest.

Arthur Cushen, of Invercargill, sends another most interesting budget: Two interesting veries received yesterday: KOFA, Salzburg, Autria, a station of the Armed Forces Radio Service, uses 750 watts on 7220 kcs., and heard to 8.15 a.m. last May, signed off at that time. They have a new card, shows map of Austria, mats from Salzburg, and is signed by Martin S. Bloom, Station Engineer. The other was a card from XTPA, Canton, China, operated by Canton Broadcasting Station, has nice white card, with green bands, calls in green on big letters in background, with details of veri. information in both Chinese and English, signed by S. S. Lee, Director. X TPA is very good every night on 11650 kcs. I’m at present trying to get some details on a very interesting station, French operated on 6010 kcs., heard as early as 4 p.m., has news in French at 4.30 p.m. sometimes relays Paris, and other times news from own studio, news on German happening) then goes into modem dance numbers, French and German vocal, yodel numbers, etc., gives call at 5 p.m., as "Radio Ruhr’’ in German, no location mentioned, station fades out at 6 p.m. Signal peaks at 4.30 p.m. Berlin or Russian operated station in Germany, terrific signal here, heard at 4 p.m. and later, sometimes relays LEIPZIG (9 7 2 0 ), XEOI, 6018, Mexico City, heard between these two, the latter signs off at 4.30 p.m. with "Sunrise Serenade.” Some other written include EPB, Teheran, 15100 kcs., news 9.30 p.m.; Bandoeng, 9.30 p.m., Eng. announcements, 7995 kcs.; RADIO SOFIA, 7660 kcs., heard poorly at 5.30 a.m. Veri. received two weeks ago from "RADIO RODINA”, Sofia, Bulgaria, using 5000 watts on 9315 kcs., the outlet on 7660 kcs. has 500 watts: sent 7 pages of information and two photos of the station, building, and concert hall. Letter stated mine was first report from New Zealand and expressed the hope that they would not be abusing my kindness by hoping that this would be the beginning of a fruitful collaboration. >;: % :Ji A long and interesting letter from an old D X-er who has just returned to civil life, our friend H. A. Callander, of Tasmania, who at present is in Victoria but expects to be back on the Apple Isle soon after the New Year. With a grand array of aerials and no less than five receivers, it is no wonder Mr. Callander can send in a good log. His report comes from Richmond and he says 10 m. is gradually showing some improvement. 20 m. band is getting up to peak around 4 p.m. The 40 m. is, he says, rather noisy. (His loggings on these bands I have sent to Don Knock.) On 31 m. PCJ was heard at excellent strength last Tuesday in an English programme from 5.30 p.m. until closing with the Dutch National Anthem. At 7.30 p.m. they announced that they would be on three days weekly: Tuesday, Wednesday and Thursday. Another good station on this band is KNBI (Voice of America) on 9.49 mcs. — heard in evening at 11.25 when giving the Hits programme. I have been mostly concentrating on 10 and 20 m. bands, but will put in the next couple of weeks on the Commercials D X side, so will forward you a more detailed programme next report. Jj« ^ ❖ Dr. Gaden has left the "Hams" for a while apparently, as I have from him some notes as follows: RNB 17.77 me. 16.88 m. heard around 7.30 a.m. at good strength; not heard at night lately. SEAC, Ceylon, 15.12 mcs. 19.84 m. very good night station. Switzerland on about 9.53 mcs. 31.46 m. is a nice signal in afternoons; no English heard. HCJB 25 and 31 m. very good; 19 not so loud. The Panama station, XO YA, is not as good as the 19 m. HCJB alongside it. Maroc 9.08 mcs. 33.03 m. at 7.30 a.m., quite good signals; no English heard from this one. XEW W the best Mexican as usual; XEQQ reasonably good. Radio Sofia 9.35 mcs. 32.09 m. is better than Belgrade on 6.15 mcs. which is usually good enough, as are many 48/49 m. in a.m. FZI, Brazzaville, 31 and 30 m. in а.m., 25 m. in afternoon, and 19 m. at night, are all good signals. All the ’Frisco Yanks are good at any time and of the W ’s old WGEO, 9.53 mcs., 31.48 m. at breakfast time takes some beating. Rex Gillett of Adelaide, says Radio Club of Mozambique is now' back on their old frequency of б.135 mcs., 48.90 m. They have an English session at 5.55 a.m. and close at 6.30. CR7AA is in relay with CR7BJ on 9.65 m.c. 31.09 m. Referring to Belgian Congo he says although Radio Nationale Belge is interfered with by PCJ and Radio Paris they can be followed at 11 p.m. on 17.77 mcs., 16.88 m. Another station that is spoilt by someone on the same frequency, believed to be Russia, is Berlin on 6.07 me., 49.42 m. This occurs at 6.30 a.m., but at 7 o’clock Berlin is identified by piano notes. (According to my records, Berlin is' on 6.072 mcs., whilst a Russian, Kamchatka Petropavlovsk is on 6.07 mcs., as also GRR— L.J.K .)
