Having formed a close alliance on so many earlier aerial ventures, it w r as only to be expected that during the Centenary race radio should ptay an iuiportan t part. Some of the entrants sacrific'd the added safety for the increased lightness and speed available by eliminating radio, notably C. W. A. Scott and his companion, but the big Douglas ’plane piloted by I’armentier and Moll had the advantage of the special direction-finding receivers installed all along the route, notably in India and the Northern Territory in Australia. Thus, blind flying presented relatively few . hazards, and darkness and poor visibility did not destroy their confidence. The operation of the radio direction-finder is quite simply explained. Consider the case of a pilot arriving at an aerodrome shrouded in fog—as some have been. He picks.up the signals from the beacon until “skip” phenomenon makes them cease when lie is directly over the aerodrome. Then another beacon, transmitting a different type of signal, is brought into operation. This is directional and its signal is transmitted so that it is parallel with the direction in which the ’plane is to land. Thus when the pilot picks up this latter signal he knows he is travelling in the proper direction relative to the ground, hut he does not know his exact position. Then comes into operation the next phase of the system. At a distance from the boundary of the ground a vertical “wall” of signals is transmitted of a distinct type, so that when the ’plane passes through them a definite indi-

cation of the distance from the ’drome is given. On the boundary itself is another vertical “wall” of signals of such a type that they can be distinguished -with certainty from the first group. Then, passing through these, the pilot knows he is right pver the field. If he cannot see the ground, the airman can make use of a “landing beam.” This is an ultra-short-wave transmission which is highly directional and forms a well-de-fined pencil of signals, so that by heading directly for their source he will take the ground at a sate angle. This particular beam penetrates the “walis” of vertical signals before mentioned, so that the pilot can pick it up and follow it in to a safe landing. So simplified has the system become that dials on the dashboard register the different types of signals and all the pilot lias to do is keep his machine in the direction that gives the maximum strength. His meters can even be graduated in terms ot actual distance from the aerodrome. In the case of the ordinary directionfinders erected across the Northern Territory, these transmit a note of a particular characteristic so that the pilot, know’ing their location on the map, can steer a course determined by the diminished or increased signal strength. Motor-car radio lias not attained the same degree of popularity here as it has in the Commonwealth, but during the week-end there w r as in the city a car hailing from the Argentine, and evidently on a world tour, which was equipped with a neat installation. The receiver w r as not visible, only the single dial for control, and the speaker was only indicated bv a perforated metal circle in the roof. Last week there was published in Sydney the first Press photograph sent by radio from England to Australia, that of the aviator, C. J. Melrose. The photograph was lodged in England at 6 p.m. Australian time. It was placed on a machine based on the fact that the human eye sees objects by the light which they reflect. The light reflected by the ' photograph was translated into electrical energy, which was transmitted to Australia by beam. There the process was reversed, and at 9.45 p.m. the picture arrived in Melbourne, whence it was sent by picturegram to Sydney. This transmission represents the opening of a new service, longest in the world, by which the Australian public will be enabled to exchange with England pictures by radio. Structural work on the new IYA studio premises and the building to house the new transmitter on a site near Henderson, Auckland, has been completed, and good progress is being made with interior work. It is expected that the installation of the transmitting equipment will take two or three weeks. It is anticipated that the installation of equipment ill the Shorthand Street building will be commenced in about a month. It. is confidently exjiected that the new station, which will have a power of 10 kilowatts, 20 tiines that of the present IYA and double that of 2YA, 2FC, and 3LO, will be in commission by the end of the year. The erection of the single 500 ft! mast for the transmitting aerial near Henderson also is proceeding apace, and it has already reached a height of 150 ft. The mast, which is of latticed steel, triangular in section, with sides about 9ft. wide, _ is being erected in sections, which diminish in length as the height increases. The mast is not pyramid-shaped, but has parallel sides with pointed ends, the bottom one of which pivots oil a huge insulator. The insulator will bear the weight of the 60-ton mast, which will be securely stayed by four groups of wires. The aerial will consist of three radiating conductors hung at equal distances round the mast. ■

4ZL, the Dunedin B station which operates on a frequency of 1220 kilocycles, 246 metres, is on the air with breakfast • music between eight and nine every morning. On Sundays the

station remains on the air until 10 a.m.

A chain of all the 53 “B” class stations in Australia has been arranged to radiate accounts of every function during the Duke of Gloucester’s visit. All -stations are working in conjunction, and, instead of each giving its own service, the resources of all are being pooled. If no indication is given, the average receiver may be assumed to consume energy at the rate of from 00 to 80 watts, which means it can run for about 12J to 16 hours "for the price of one unit. Speaking in London of future developments in Empire broadcasting, Mr Noel Ashbridge, chief engineer of the 8.8. C.,. said that the service would be subject to changes for some time to come. The results obtained, as they are made known by reports received from listeners and official organisations, are continuously reviewed. During the past 18 months, said Mr Ashbridge, the 8.8. C. has carried out a number of experiments at Daventry with a view to determining the most suitable type of aerial, and the erection of two 350 ft. towers has just been completed, so that experiments may be pursued further, a preliminary investigation having shown that high aerials give considerably better results than the low ones originally provided. It has often been suggested that the power of the Empire transmitters should be increased, but, while an ultimate increase may be found justified, it is felt that for the present it is desirable to concentrate on obtaining the most suitable transmitting aerials.

Mr E. T. Fisk, chairma.n of Amalgamated Wireless (Australasia), Ltd., speaking in Sydney recently, said that so far wireless had been employed constructively and beneficially to the human race. One of the most interesting features of broadcasting development was the application of the shortwave sj-stem, which made it possible for an individual to communicate at suitable times with the whole world simultaneously' and practically instantaneously. In a few years, lie felt confident, it would, be possible for the King to speak to his whole Empire at the same time. Such an instrument in the hands of the individual had grea.t possibilities for good and must exercise a profound influence upon international thought. If a common tongue could be found, then wireless would become the greatest peacemaker likely to be evolved by human effort. Mr Fisk said he believed television was a certainty of the future, but an uncertainty of the present or near future. This applied particularly to moving pictures. Still pictures could now be successfully transmitted by wireless, and the neces sary apparatus was being installed at the beam station. This would enable photographs and documents to be transmitted to London in about 20 minutes.

Of an estimated total of 42,540,239 radio receivers in operation throughout the world and 1497 medium-wave broadcasters,, the United States lias 18,500,C00 sets and 585 sending stations, according to a survey conducted by the United States Department of Commerce. The regional distribution of receiving sets in the world shows North America first with a total of 19,769,045. Europe is second with 18,594,605, and is followed in order by Asia, 1,982,712; South America, 909,867; Oceania, 639,338; Europe-Asia (Russia and Turkey), 605.500, and Africa, 93,072. Ail official list of the short-wave stations of the world comprises 2400 transmitters. “REMEMBER THIS RADIATION.” Remember that, when concentrating on weak signals at night, it is a noticeable fact that greater attention may be focussed on the transmission if "all the lights in the room are switched off and only the pilot light on the receiver remains. Slow manipulation of the dials will also often locate stations otherwise missed. N.Z. DX CLUB. MONTHLY MEETING. The monthly meeting of the Palmerston North branch of the N.Z. DX Club was held last week. Mr J. P. Cowlisliaw presiding over a good attendance. Formal business was of a light nature and was soon disposed of. Members expressed sympathy with the club’s technical advisor (Mr 11. Rowlands), who is at . present ill hospital the victim of an accident. The proposal to obtain for members a supply of American stamps was reported to have been abandoned, as the exchange rate made the benefit infinitesimal. Members displayed the verifications received by them for the month and some good loggings were reported. The monthly competitions conducted by the branch resulted as follow: —Overseas (senior): G. Dalcfield, W.MAS, 1; G. Vining, WACO, 2; E. Seeley, WREN, 3. Overseas (junior) : J. M. Todd, JOOlf, 1; A. R. Lacey, KQW, 2; E. Seeley, WREN, 3. YK competition: G. Dalefiold, VKSIIP, 1; J. C. A. Donaldson, VK4PK, 2; J. P. Cowlishaw, VK2LB, 3.

Mr G. Vining, of Palmerston North, has donated a silver cup for competition among the junior members and added interest in this section has already been noticed. The branch passed a vote of thanks to Mr Vining for his generosity. At the conclusion of the ordinary business of the meeting supper eras served, and members indulged m ])X topics until a late hour.
