RADIO WORLD.

(By “Listener In.”) “Listener In” will bo pleased to receive items of interest pertaining to wireless. Lately several enthusiasts have beer inquiring about the Japanese stations I. hope the following information wil prove of value : Metros. Watts. JOAK. Tokio 375 1000 JOUR, Osaka 385 SUU JOCK, Nagoya. 30U 1000 Our time is 21 hours ahead ot Japan’s time. Some of you have thought that you have hoard a station in tiie .Philippine Islands (Manila). There is one station in Manila, with the call sign KZRQ, .'{TO metres. The New Zealand time is about three and a half hours ahead of KZRQ. Bow mail}' have logged this P It will not bo out of'place to give 'the call signs, etc., of the main Australian station;;:—■ Met res. 4QG 387 3LO 37! JAR 481 2GB 31.0 2BL 373 SCL 11! )7 7ZL 516 71)\ 31:5 2FC 442 Quite a lot of pleasure can ho had by listening to the Morse. Onco you have mastered the code, the rest is I easy; that is, provided the Morse is i not too fast. It is wonuorhit what I vou (inn do sometimes, hut we are hound to secrecy, and must not even tell our friends who won a iootbaU mat ch. “THE PSALM OF RADIO.” , Radio is my hobby, I shall want no . other. . . , It mnketh me to stay' home at night, it leadetli me into much trouble. | It drawoth on my purse. I J into the p;tilis ot debt lor its sake. 'Yea, though I _understand it perfectly, it will not oscillate. Its concerts and speeches, they comfort me; Yet it will not work in the presence ol my friends. I annoint the coils with shellac. But the valve spiileth over. Surely the bug will follow me all the days oi my .life. And T will dwell in the house ot a radio amateur forever. There is another enemy to good radio reception in this city. I make rotormicc to a violet or blue ray outfit. Ibis I transmitter of electrical energy is to Ibo beard in tile evenings. Probably ■ you will have noticed this di slur bailee. "Once this noise ceases, the ether vibrations or oscillations come in o.k. Let's hope this “death ray” will operate in the daytime only. i While the rights of broadcast stations to the air arc still to be determined, the city of Portland, 'Oregon (IJ.S.A.) lias outlawed man-made interference by an ordinance prohibiting the operation, between 7 and 11 p.m., of any electric device causing interference to reception, and taxing each Mich article a 100-clollar license fee h'pay .. for the inspection. Other citicS are contemplating similar action. “WAVELETS.” IYA has been fair. 2YA is awful—la ways. Let us hope that wo will bo able to say soon that 2YA is always awfully nice. Did you notice liow very weak the Australian stations were mi Sunday, i 24i1l April?—2BL was the strongest. • And, again, did you hear the “death j ray” machine during the week? : By “death ray” machine, 1 j mean tho violet, or blue ray, outfit' that is being operated in Timaru. D ! certainly is death to wireless while in operation. One more comp'ant. Will the I “Bolshee” who causes all tho howling please ea’l in the man who sold tin' set, and have it neutralised, and buy from him tho little book entitle-* “Ether Manners,” by “Listener-in.” The concert lrom the i 0.. u iaail in Auckland on Sunday, 24th April, was excellent, in fact, IYA can boast of an almost perfect transmission. Why cannot 3YA continue its transmission till 10 p.m. on Sundays It’s the same old story—the North Island gets all tho ice cream. Wake up, 3YA. You boasted at the opening that your station was the most up-to-date in the Dominion. I liked the announcer from 3YA on Sunday. He had a splendid voice, and spoke quite naturally. That is one asset 3YA has, and one that JY'A hasn’t. The Anzac service from Auckland, in Iho morning, was fair ’phone strength, but, as usual, there was tho “Bolshee” howler trying to blow up the ether.

3YA cannot be congratulated on its ; relay on Anzac Day. Why do tliev ' not liavo a try-out before the actual ] function takes place ? The sooner tho j N.Z.B.C. appoint an engincei-in-chief | tho better. j The annoying sound heard from : 3YA, on Wednesday, Thursday and Friday evenings tva.s the fault of 3YA. j This continual howl made reception al- i most impossible. I believe this station was aware that tho howl was in ovid,- j ence on Wednesday. I wonder what ' excuse they havo to offer this time. 1 Faulty or overheated values Come on j 3YA give us .your best, otherwise we j will all be listening to the Aussies. So j far the Now; Zealand stations are not j worth the license paid. i The Broadcasting Company has at last altered the wavelengths of 3YA and 4YA, and with what beneficial re- ) suits. Judging by the transmissions on Wednesday evening the change was a ! failure. _ | As regards 4YA, well, it’s no wonder ; they havo so much rain and wind m j the' Haggis city. Some eighteen months ago the New Zealand if road- j casting Co. wero reputed to have said (and T believe tho Prime Minister also said), that wo were to havo the finest broadcasting service in the world. Weil listeners in, we have not received what we. were promised. The transmissions from 2YM, 2AQ, 3AC, fYA (old station) and 4YA (old station) three years ago were perfect as compared with the trash wo receive at times from the present stations. It is a godsend that we have Australian \ stations to “tune into” ; and we get ■ the Aussies for nothing. j I wonder what has happened to our representative on the Board? ) • I would like to point out to one en- | chusiast that it is not lawful to use the telephone wires for an aerial. 3LO made a capital job of the Duke’s J speeches (apart from static). I 2FC, 2BL, and 3LQ are very strong at 7.15 p.ni. Amateurs with good sets should be | abb' to tune in 2BL at 4.30 p.m. j Tho Yanks are only fair. , I believe 2YA will operate on a wavelength of j 440 metres. Mr S. For your information I bare i two set.s, one short wave, and one airzone receiver employing one stage radio frequency, neutralised detector, and three stages of resistance coupling. “Enthusiast” writes:—A short time ago I purchased a neutrodyne set, and . 1 was wondering if any medium price . sets could beat it. I have received on j this set, 2BL, 3LO, 2FC Sydney, j

NFON San Francisco, ail the New Zealand stations, including tile small stations, the theosopliical station, Sydney, .end seveial stations ot wliicii 1 could not get the number or name. The i eceptiftn is splendid, and 1 seldom work the five valves. I find by usiim only tour or three valves, X cut out a lot of static . and howling. X have heard quite a few of the liigker-power-ed machines, but have not heard one yet that can give the clear and good tonal reception that my set gives. L do not know whether you have heard it, but would like to hear your view on this machine. I look forfward to your notes on wireless in the “Herald” aiid have put into operation a few of the hints that you have so kindly given. X an ampiion loud speaker AR 19. Which do you recommend? I shall be very pleased to see your reply in the “Herald.” Answer: —X have heard the set; in fact X have heard the majority of the sets in New Zealand—some good and some bad. The results you are receiving are excellent. As 'regards the loud speaker, X always maintain that AR 19 ampiion is as good aq one could wish to have ; as a matter of fact amplion speakers are world-lamed. Thank you for your your complimentary remarks. More reports please. X am afraid a largo number of amateurs are radio shy. Why don’t you sent in your results? Some fans are very helpful, and send along Weekly reports, but wliat about the others?
