P.02 - Editorial Notes

A PERSONAL MESSAGE.

With due apology for the too abundant use of the word "I". I cannot express how happy I am at the prospect of again devoting all my energy to technical radio matters. During the past two years I have had to deal with the prosaic matters of business, of broadcasting programmes, publicity and the like. Now I am right back in the thick of the technicalities which I love. From now on my days and nights will be spent fiddling around with novel circuits, new valves, powerful amplifiers and the rest of the things which mean so much to me. What is more to the point there will be less restriction for my only thoughts need be to please those whose heart beats as mine. No need to consider the masses, no fear that I will have to please people to whom a circuit is like Chinese. Before I go further I feel that I should express the satisfaction I feel in carrying on a technical policy of which anyone might well be proud. In the past the Australasian Radio World has held my esteem for the soundness of its articles, the accuracy of its circuits and the general way in which the magazine has been conducted. I feel that only a few minor details need attention to make the paper worthy to maintain its rightful place as Australia's only one hundred per cent. technical radio journal. Among these changes I might mention the addition of a Junior Technical section, to be conducted by Alf. Barnes, whose articles have been a feature of "Wireless Weekly" for the past couple of years. Another feature to be strengthened is the query service. Readers should be assured of prompt and effective handling of their letters, with replies either free of charge in the columns of our pages, or by mail on payment of a small fee. Several other minor improvements should be noted during the next couple of months and I am sure that they will be duly appreciated. No startling changes in style are contemplated, and the services of Earl Read, who has made the paper what it is today are being retained as Associate Editor. A. G. Hull

Shortwave Review

Conducted by Alan H. Graham.

More New Stations Heard )f. Conditions Improve As Autumn Approaches * Byrd Expedition Heard On 20 Metres * U.H.F. Bands Improve A Little * Full List Of Month's Loggings * QSL Exchange Bureau.

Review Of Conditions. Since the middle of February the approach of autumn has resulted in a marked improvement in signals on all bands; and reception conditions are now very good throughout most of the night and day. It is not sur- prising therefore that several new stations appear in the list of the month's loggings. New Stations. The attention of readers is drawn to the following new stations; the majority of them have been heard quite well, and DX fans should have little difficulty in adding them to their logs. The new Argentine station, LRA-31 h8.s been heard Rome mornings on the same frequency as WRUW-11730kc., 25.58m. Egypt now has a regular shortwave transmission, through a station on 7860kc., 38.17m. This station has been heard quite well between 4.30 and 6.30 a.m. Gall is thought to be Sl!X, but this has not been verified. A new Australian transmitter is using VK3ME's old frequency; this is VLQ15, 9590kc., 31.28m. Listeners will also have noted changes in the frequencies of VLR-3 and VLW-2

A new NIROM station, carrying the same programme as YDC and YDB, has been reported on 11910kc., 25.19m. Although not heard yet in our locality, it is reported at good strength from Western Australia. Rangoon, known to DX-ers thro1.1gh XYZ, has another transmitter on the 49-metre band- on 6056kc. Call is un- known, but no difficulty should be experienced in logging this station, as it is much stronger than XYZ.

The latest Paris Mondial station heard is on 9520kc., 31.5m. It is apparently used during the afternoons in place of TPC on 9680kc. Unidentified. One or two ,;mystery" stations have been r eported during the month. One of these, heard bv our W.0. observer, Mr. Pepin, is an Eastern station on 34 metres. He thinks it may be a Jap-possibly JIB, 8650kc., 34.71m., or perhaps ZBW, Hong Kong, back on their old channel of 8750kc., 34.29m. Another station reported by Mr. Pepin is an Italian 'phone station heard testing on approx. 18.4m. In

all probability this would be ITK, It. Somaliland, 16385kc., 18.32m., or IRY, Rome, 16117kc., 18.61m. A third unidentified station is a new South American on the 31-metre band, on the same frequency as WBOS. It is heard in the early mornings,· and is probably a Colombian, but QRM renders the obtaining of further details most difficult. Byrd Expedition. 20-metre fans will doubtless be con- centrating all their attention on logging the stations operated by the Byrd Expedition in Antarctica. Already Mr. Hastings, one of our Queensland observers, has succeeded in logging KC4USC, one of the Byrd stations. This station, together with KC4lTSA and KC4USB, operates on 10, 20 or 10 metres; but the 20-metre band would seem easily the best bet for reception here. Australia Tells The World. Australia is certainly telling the world wlhere she stands in the present conflict through the new VLQ stations of the Ministry of Information. In addition the A.B.C. prngramni.es are relayed through VLR and VLW. Acknowledgements. We wish to acknowledge reports from the following :-Messrs. Ban tow, Neill, Hastings, Chapman, Taylor,

P.30 - Shortwave Section - Waverley Radio Club Notes

WAVERLEY RADIO CLUB NOTES With the commencement of the New Year this club has made a determined effort to maintain the pre-war standard of activity during the meetings. At the first meeting in 1940 mem- bers were treated to another of those interesting demonstrations by Jack Howes. On this occasion Jack recorded the voices of those present. The highlight of this event was a vocal trio of jitterbugs who crooned some war songs into the mike. The following week Mr. Howes again entertained with a full-length movie programme which included Charlie Chaplin and a cowboy film, causing great hilarity. On ,Tanuary 23 your scribe, D. Dunn, came forward with a modest talk on the design of receivers. It is interesting to note that the discontinuation of amateur transmitting has not affected the enthusiasm of the club members, the only absentees being those who are in camp.

P.32 - Shortwave Section - Ultra-High-Frequency Notes

Ultra-High-Frequency Notes Conditions Improve Slightly. As hos been the case in the post few years ultra -high-frequency conditions hove improv· ed since about the middle of February. Although, at the t 'nie of writing, signals on 10 a'1d 1 l metres ore by no meor.s strong, they arc much more consistent than earlier in the year. The l 0-metre amateur bond hos improved a good deal, and this would seem to indicate that the police bonds may open up again for a while before winter. 11-Metre Band Loggings. WSXNU, 25950kc., l l .56m., Cincinnati: Still the best station on the bond, with a fairly good signal practically every morn ing. W4XA, 26150kc., 1 l .47m., Nashville: Greatly improved during the last few weeks, and nearly a s strono 'as WSXNU on some morn ings. W9XPD. 25900kc., l l.58m., St. Louis: Heard aimcst every morning, but always a weak signal. W9XH, 26050kc., l 1.52m., South Bend: Difficult to log, but sometimes heard before closing at 9.30 a .m. Verifications. An interesting verification is to hand from the County of Los Angeles police transmitter, KQBV, 3 l 900kc. This confirms our report of November last, and mentions that KQBV uses a power of 500 watts. Additional verifications from the Crosley Corporation station, WSXNU, Cincinnati, on l l metres, gives the latest schedule for that station as:-Week-days: 10 p.m.-4 p.m. next dov; Sundays: l 1 p.m.-4 p.m. Monday.
