AMATEUR WIRELESS.

INTERESTING JOTTINGS. (By "Vernier.") At present' radio enthusiasts throughout the country arc asking what will become of the VLDN station after the Exhibition closes. Nothing definite has yet been realised by Broadcasters, Ltd., but it seems cvi-. dent that VLDN will continue operations for some time after May Ist. It Is also understood that the sot will be removed, and will not form one of the four stations to be controlled in the chief centres by the company. Apparently the set for Duncdin has vet, to-be imported and VLDN .has been. merely a stand-by; a plant as temporary in its nature as the Exhibition itself despite its worth. During the past wcelc VLDN has continued its good work, and the pro--grammes and quality of the transmissions have been good. ; Mr A. n. Harris, managing director, and J. Bihham, engineer of the Dominion Broadcasting Company, are at present in Auckland on matters connected with Ihe new radio service from Auckland. After behaving most amiably for some lime, static has been very troublesome during the week, and has considerably interfered with distant reception. A fortnightly radio magazine is shortly to see the light of clay in Auckland. It is .announced that both Svdney Broadcasters and Farmer's will go up on their 15,000 watt input at the end of this month. There have been over, 40 applications for the position of concert organiser for the Auckland broadcasting station. No appointment has yet been made, but an annouccment is expected shortly. The interior fittings of the new Auckland broadcast studio arc receiving the attention of Mr Bore, Western Electric technical official, who is coming to Lake initial conlrol here. lie will include all the latest features that recent Homo experience has proved desirable, and will probably abandon the custom of complete curtaining of walls and ceiling. Modern practice has shown that better , effecls are oblainablc by partial curtaining and the use of moveable screens.

"Broadcast Reception in Theory and Practice" by Lawrence Pritchard (Chapman and Hall, London), is a book that should make a wide appeal to radio men who revel in the literature of their hobby. It is a volume that strikes the happy medium between a mere constructor's text-hook of directions, and a deeply technical treatise that carries one far into the intricacies of electricity.

Mr J. D. Chisholm, giving evidence before'the British Broadcasting Committee on behalf of Secret Wireless Ltd., said the company had perfected a system of secret wireless which enabled wireless signals to be . received only by those for whom they were intended. It was possible by the company's method for individuals to communicate privately with each other by wireless. By the Secret Wireless system a great range of programmes operated by different broadcasting companies from different stations could be made available. The Australain broadcasting sta!ti6ris,,continue to give pleasure .to. New Zealand listeners by their varied and attractive programmes. . Having* in mind the tonal qualities of. the reproduced sound, a northern writer favours the Melbourne station 3LO-. The transmission from this station on Good Friday of a performance by the Melbourne Philharmonic Society of Mentlelsshon's oratorio "Elijah" was a veritable revelation of the possibilities of broadcasting. The performance of the five soloists, the choir of over 200 voices, and the rchestra of 70, together with the technical fection of the transmission, constituted the most perfect broadcast' this writer has heard. The New 2F.C Station.

On Monday, March 29, the new 2FC station of Farmer and Co., Ltd., Sydney, was officially opened. The opening of this stalion marks another milestone in the radio progress of Australia. Nearly all the Class "A" stations are now working on powers in excess of 0000 watts, and the remarkable distance at which these stations are being received bears excellent testimony to the capabilities of their operators, 2FC, Sydney, and Farmer's Perth (GFW) are the only Australian exponents of long-wave broadcasting. Mr Hughes Opens 2FC, Sydney

"We are literally citizens of the world," said Mr Hughes in declaring the station open. "Provincial barriers have been broken down and we are all neighbours. Before long the Prime Minister of England will speak to the whole Empire by the aid of this wonderful wireless." He congratulated those responsible for the new station on their enterprise. Station 3LO Several country broadcasts are scheduled to appear on 3LO's programmes shortly. The first of these will be the Kyncton competitions on April 20. Another land-line transmission from Bcndigo is scheduled for May 22, and should prove as successful as previous items from the golden city. These activities in country transmissions do not prevent 3LO from continually adding to its already large number of city landlines. The work of these is going ahead rapidly and the time is not far distant when all the important centres of entertainment will be connected to 3LO. Many temporary lines are being laid down, the latest of these bethose to Wirth's Olympia and the Queen's Hall. The Sydney Exhibition.

The Sydney Radio and Electrical Exhibition, which is to be held in the Town Hall from May 3rd to May 8 is creating great expectations. Many interesting exhibits arc promised in the amaleiir section, the most enterprising entry, perhaps, being that of the Wavcrley Radio Club, which has promised to enter a short-wave transmitter, and accept any non-commer-cial messages from any one in the building io any part of the world. These will be relayed to a local station for transmission to their destination. 2HL's New Studio. Station 2BL is very proud of the new .studios, situated in the building of the Australian Mercantile Land and Finance Company, better known as Adyar House. There is one studio for band and orchestral performances, and a smaller one for Hie vocal items and lectures, both artistically decorated. The transmissions have been considerably improved since this change-over was marie. One of the features being presented from these studios is 1 lie "Trial Nights." which occur every "Wednesday evening, when building artists are allowed Io try their merit. There is'also a competition in connection with this feature, the prize being two guineas for the first envelope opened which agrees with the decision of the station's musical director. j
