*8? NOTES AND PROGRAMMES V

(By

"Director.”)

j Frequent repetitions of the same litem affords listeners an excellent opportunity to memorise both words and I music of songs—but it is well to remember that enough is as good as a i feast. Reception of the Australian stations has been most erratic during the week. One night they are heard at good volume, the next very weak, accompanied by persistent fading. In Australia quite a number of factories and warehouses have radio sets installed in their luncheon rooms. To eater specially for the audiences gathered round these at the mid-day meal hour, one of the Sydney stations, 2UW, is arranging a daily session of instrumental and vocal music. For the first time Auckland has to give pride of place to the Wellington j postal district for the highest total of [ listeners, Wellington, with 12,973, having 29 more than Auckland’s total. Very good conditions have ruled durling the week for reception. On TuesIday evening 4YA, Dunedin was excep- ; tionally strong and very steady. 2YA, • as was to be expected, came in at firstclass strength. IYA was also heard at • good strength for this time of the year. . though fading was noticeable at times. j It is unofficially stated that a license ! has been issued to the Anglican Broad- , easting station. Dual wave-lengths of i 230 and 30 metres are to be used. ' Mr Amery was the first British Min- ’ ister to speak direct from Australia to Great Britain. He spoke on a Monday and was heard on a Sunday.

j The Crosley “Bandbox,” an entire- ■| ly new 6-valve totally shielded rei i eeiver, possesses tone never before pos- • i sible in any receiver at anywhere near - I the price will shortly be placed on t'he New Zealand market. This receiver embodies patents covered by the seven 1 leading radio corporations of America and will sell for about £45 complete.* The inclusion of weather forecasts in the evening programmes appears to be amply justified, judging from the interest one sees taken in them, especially ’ by the farming community. The Post and Telegraph Department ■ is ‘‘out after” those people, especially those in country districts who hold the telephone line for interminable periods with a loud speaker at one end and an • interested group at the other. The telephone is not to be used as an ad- ’ junct for spreading radio entertainment. Much of the noise in valve circuits is due to the grid leak. Those variable carbon varieties are a source of 'trouble from the beginning of their life to the end. Although they will give service for some little time, as soon as the resistance is lowered the carbon discs become packed and cracked, and the leak becomes ineffective. Such noises are s<4ietimes termed “valve noises,” which is incorrect. The use of metallised filament fixed grid leaks is recommended. Acts 2 and 3 of “The Student Prince” will be transmitted by 3LO, Melbourne from His Majesty’s Theatre to-morrow evening.

Professor Bernard Heinze and his University Conserva.torium Quartette are featured in the programme at 3LO, Melbourne, for Sunday evening. i The “Trav-ler,” a new portable 5i Valve receiver for either home or port- ‘ able use, when folded occupies space i less than a foot square, and sensitive !to the last degree. Always ready for i use, in the car. on the beach, anywhere. I Just open the lid and switch on. [Weighs only a few pounds. Book your orders now and secure one for your holiday trip. Complete price £29 10s. Terms £lO deposit. Obtains ide only from D. A. Morrison and Co., Electrical and Radio Engineers.* The tone quality of the receiver may be often improved by shunting a condenser across the speaker or Lead phone terminals. The proper capacity of this shunting condenser is best found by (trial. Any capacity from .005 mfd to | ,02mfd. will give excellent results. The use of a condenser for this purpose will decrease the volume of the receiver to ja. very slight degree, but the added ' quality of reproduction fully compcnI sates for the loss in volume. I The electromagnetic energy emitted I from a broadcast station antenna radiates in every direction, and goes on into space with diminishing strength, but nevertheless continuing for ever at the astonishing speed of 186,000 miles per second. Next Week’s Sports. Friday, Dec. 9 —N.Z. Athletic Championships, relayed by 3YA. Announcer, Mr Allardyce. Saturday, Dec. 10.—N.Z. Athletic Championships, relayed by 3YA. Announcer, Mr J. K. Moloney. In the evening of the same day the Cycling Championship will be described by Mr J. K. Moloney. Saturday, Dec. 10.—Wellington Trotting Club (Hutt Park). Announcer, Mr Allardyce. The plate voltages ordinarily used in receiving sets are 16£ to 45 volts on I the detector valve, 90 - olts on the am- ! plifier valves, and 135 volts and up on j the power valves. from D. A. Morrison and Co. now.* I The Gilfillan Neutrodyne Broadcast i Receivers are the standard of quality throughout the world and due to their extreme efficiency, combined with great simplicity of operation and attractive appearance, are undoubtedly the best known and most popular receiver on the New Zealand market. Enthusiastic appreciation of the performance of the Gilfillan Neutrodyne Receivers is daily being expressed all over the Dominion. A Gilfillan Neutrodyne is properly constructed and adjusted so that under no circumstances can it howl or squeal, causing trouble to the user and to his neighbour. In addition, it possesses a higher degree of selectivity than other types. It is extremely sensitive and the quality of its reproduction of sound is unusually fine. Emmett’s, Radio Specialists, 62 Victoria Avenue, Wanganui.* New Discoveries. Speaking before members of the Sigma Xi Society at their annual dinner at the Hotel Astor, Dr. E. F. W. Alexanderson, consulting engineer of the General Electric Company declared that the knowledge and entertainment obtained from the radio at present are only a .fraction of the value which new discoveries in radio will bring. He. predicted control of power by radio, succeeding the massive machines now required to do this work, was just a short step ahead. “The electric power industry cannot remain much longer untouched by the discoveries of radio,’’ ho said. “It is just waiting until this new knowledge has been widened and matured, so that it can be put into use on a wider scale, and this is the real significance of the entrance of the elec- ( trical industry into radio —and the latest branch of it, television.”

It is of utmost importance that the existing valve in the radio power unit be replaced by the same type of valve. The substitution of another type may lead to serious trouble. Amplifiers are divided into two main classes: Those designed to amplify speech and music directly, or audiofrequency amplifiers, and those for much higher frequencies, known as radio frequency amplifiers. The design differs quite widely between these two. Thus an audio-frequency transformer always has an iron core, made up of laminations —•' thin sheets or of soft iron wire. This construction is to reduce the losses in the iron. A radiofrequency transformer, on the contrary, has ?.n air core or a core of iron filings. A second marked difference is in the number of turns of wire used. An au-dio-frequency transformer has several ' thousand turns on the primary winding, and from three to ten times this amount on the secondary. A radiofrequency transformer for frequencies from 660,000 to 1,200,000 (wave-length from 500 to 259 metres) will have only a few hundred turns on each winding. DELAYS BETWEEN ITEMS I NEW STTOIO AT IYA Distressing features of transmissions from many broad casting siatums are the iong intervals whica some ionics occur between items in the prt g.aninp’S. I ihese intervajs are, o;i ocvasmus, several minutes long. A.ho- ug i probablj few listeners ha\ c noticed it, the intervals seldom occur :.i ti e programmes from 3EU, and if there is any pause at ail, it is never so long as one minute. The secict '-i this perfect timekeeping wa< /■cveaied recently by Mr W. i. Cornier, ti»o manager ol 3L-O. Air Conder had a wireless set in bis oiiice beside liira and he tuned in t» the station. At the cvncliu-am ot the item Mr Conder began to count. Before he Lad counted i-lirc'.- the unnoun cer begun to announce the next item, which began two seconds after the an Ino lineament. “If 1 can coup.-, five belt ween the items,” he s.\iu. “i teie- ! phone to the studio to find the cause !of the delay.” . I I Considering the fact that IYA is | I hampered by having the use of only une 1 j studio, the average time, between items iis surprisingly small. A second studio , is new being put into order for broadi casting and when this is completed | there should be only a few seconds beI tween succeeding items. When the stu--1 dio building at IYA was being erected 'provision was made for a smadi studio as well as the large one, but it was found necessary to use the smaller stu--1 dio for office accommodation. The office j is now being.moved upstairs so that the small studio may servo its proper function. Z sr- s, ■' /
