It is very evident that the present demands in the matter of tropic-proofing will ensure that the commercial sets of the future will not be affected by humidity. Radio sets for the forces are tested by operating them with a hose playing on them. An army receiver is built in anticipation of being thrown overboard into saltwater, dragged up the beach on the end of a rope and then operating to perfection as soon as it is switched on! Country readers will be pleased to hear that the shelf life of batteries has been vastly increased through improved construction methods for providing better internal insulation. Post-war batteries should last nearly twice as long as previously. Australian technicians are also gaining valuable experience in handling communications-type receivers, some of the latest jobs being available "in official circles." It is expected that these designs will be studied intently and their best features digested so that Australian enthusiasts can hope to be catered for adequately with sets of a type which have previously existed only as pictures in American magazines. - A.

J. Keast NOTES FROM MY DIARY - YES, WE HAVE NO BANANAS - Yes, and we have no Fiji broadcasts either. Just after conducting a series of tests and producing a splendid signal from 4.55 till 9 p.m. on 6.13 mc., VPD-2 faded out as quickly as it came. But I am told the withdrawal is only for a short period. I am sure their return will be welcome, particularly if they continue to relay the favourite American transcriptions. ARTHUR CUSHEN - Mr. Arthur Cushen, of Tnvercargill, writes me that he received a fine card from KGEI verifying his report on their 7.25 frequency. He says the card shows Transmitter House, and a new Box Antennae. Arthur's total of veris. must now nearly reach that of Flying Officer Ray Simpson. Talking of KGEI reminds me they are back again on 15.53 mc., 19.57 m. I do not know their schedule, but when closing at noon it is given in full. BY KILLARNEY'S - I almost said, Lakes and Fells, but read on: No! all that timber you see at Killarney, Queensland, is not for an American Military Hospital. That, together with those many coils of wire, those boxes of insulators are for the listening-post of Dr. Gaden, who, from the flat in the west (and later a flat in Brisbane) has moved to the hills of Killarney, and from 1700 feet above sea level will send to this magazine news of the Cubans, Central and South Americans and those other hard-to-getters. AMERICAN NEWSLETTER - Prepared by Columbia Broadcasting System and read by Dave Hamilton, this is a nice start for the day. It is at present coming through very well on either WCRC 11.83 mc., 25.36 m., or WCBX 15.27 mc., 19.64 m. at 7 a.m. I prefer the former for signal strength and clarity. NEW YEAR RESOLUTIONS - Notwithstanding all the good resolutions for what we trust will be Peace Year, I must complain of the very poor quality of the BBC Radio News Reel. I am not referring to the subject matter, but the processing. Sometimes almost half of it should have been scrapped as it is nigh impossible for even a regular listener to follow it. Sounds to me as though some substitute for the old record base is being used. And while on the BBC, have you noticed the metronome that appears to be in the background when the 10 p.m. news is read? A BREATH OF THE PAST - An air mail letter from Flying Officer Ray Simpson reached me on Christmas Eve. As usual very brief (only time he is verbiose is when sending a report overseas for verification), but it was great to hear from him. I am sure we all hope this year will see he and all other soldiers home, and for good. SHOULD WE COMPLAIN? - And another soldier who was a great DX-er writes. I have not the least idea where he is, but Sgt. Raymond K. Clack, in a most interesting letter, gives some idea of listening conditions presumably under the sheltering palms. Amongst other things this is what he says, "Listening conditions here are terrific. It may not be so bad on frequencies above 7.5 mc., but below that one has to rely on VLQ and VLQ-2 for anything of entertainment value, although GRM, 7.12 mc., in the Pacific Service is not so bad at times. "Noise level is terrific. Just try and take as a comparison the 49 metre band at its noisiest in Sydney and multiply that noise by three or four times and you'll have some idea of the noise level here on frequencies between 7.5 and 3.5 mc. Add to that a high atmospheric moisture content, which, by affecting coils, etc., causes a receiver to drift, and one has another difficulty with which to contend." Should WE complain? P.20 - Shortwave Section - New Stations New Stations KWIX, 'Frisco, 11.87 me., 25.27m.: First heard December 2. Another outlet for the Associated Broadcasters and from opening at 6.30 p.m. when it joins its sister station, KWID, in French, puts in a very fine signal untily about 8.40. At that hour VUD- the new All India Radio Station in Delhi, switches on his carrier, sometimes a little earlier, and being on the same frequency it is a fight for best signal. Odds are in favour of KWIX and they can be generally copied till closing at 9.15. Report are asked for, so, you veri.-hunters, get busy. AFHQ, Algiers, 18.025 me., 16.64 m.: This further outlet for The United Nations Radio is mentioned by Mr. Matthew'!< of Perth. They open in good strength at 1 u.20 p.m. AFHQ, Algiers, 11.883 me., 25.24m: Mr. Ted Whiting (Radio & Hobbies) tells me of this one. Opens at 7.57 p.m. with anthems. A BBC relay is given at 8.15. WRUA, Boston, 7575 kc., 39.6m.: At time of making this note I have not heard the new transmitter for the World Radio University.

VWY, Kirkee (India) 17.94 me., 16.72m. : This is another new one submitted by Mr. Matthews, of Perth. He heard them at 1 0.30 p.m. calling the BBC. VWY, Kirkee, 9.045 me., 33.16 m. : This has not been heard here yet, but is reported in "The Broadcaster" as audible ot 9 a .m. HER-, Berne, 18.45 me., 16.26 m.: This is the trequency of the old League of Nations station, HBF. It was brought into use on December 18, for use in parallel with HER-5, 25.61 m., in the Austra lian service. Signal is only fair, reaching R4 Q3 on the occas- ions I listened. Schedule is Tuesdays and Saturdays from 6.30 till 8 p.m. with English on Tuesdays and the National languages on Saturdays. British Mediterranean Station.: Have hesitated to mention this one before, but they have now apparently settled down to regular schedule and are to be heard on three frequencies at times, viz. : 9.67 me., 3 I .02m.; 11.71 me., 25.62 m.; 7.215 me., 41.58 m.; Opens at 11 p.m. with musical note. 1 I .45 Italian.

I om not sure of 41.58 m. schedule, but it opens at 5.30 o.m. in German. (Mr. Cushen, N.Z., mentions Mediterranean Station heard on 9.90 me., 30.30 m. from 5-5 .30 a.m. and on 9. 19 me., 32.64 m from 4 pm). AFHQ, Algiers, 6.04 me., 49.67 m.: This one is reported by Mr. Lindsay Walker of Applecross, W.A., and Mr. Arthur Cushen of N.Z. Heard at 5 a.m. with news from Algiers and at 6 o.m. with "Voice of America" news at 6 o.m. Very good signal till closing at 10 a .m. WCRC, .New York, 6.12 me., 49.02m: Mr. Cushen reports hearing this one at 5.45 p.m. GWJ, London, 9.53 me., 31.48 m. : Heard irre.gularly for some t ime, but schedule is now 8-11.45 p.m.; midnioiht-1.30 a.m. GWI, London, 7.25 me., 41.38m.: This is a new one and is heard 5 a.m.-2 p.m.; 3.45- 8.15 p.m. GWK, London, 6.165 me., 48.66m.: Another new BBC outlet.

P.21 - Shortwave Section - Short-wave Notes and Observations Shortwave Notes and Observations AUSTRALIA In the second transmission to the British Isles, VLI-2 has been replaced by VLI-8, 17.80 me., 16.85 m. This is fortunate as it leaves the new KWIX in the clear for an additional 15 minutes, excepting that our friend VUDin Delhi, puts his carrier on long before 8.45 p.m.- L.J.K.
