BUDAPEST STATION. A kfitfVs wireless broadcast ntr, station in to be established at Budapeston « I’trength of 110-120 kilowatts. THIS WEEK’S HINT. One of til© most efficient mc'.bods of cbhilecting a picfc-np to a set js uee inpedahee coupling in the arsl audio Stage, employing the secondary of ah ordinary transformer as tin: choke. This allows the pick-up to go permanently across the pmnart. avoiding the need for any sv. .idling arrangements. 'stage act by television. A television vaudeville act, shown on a screen lilt by 7ft, is being added tb‘ the regular programme of a theatre at Schenectady, I:.S.A. liffst autumn the largest television picture shown by Dr. Alexandersort, of the General Electric Co., of Schewas 14fn. square, and Ins first picture in 1927 was only -ffin. square. The audience a few weeks ago watching the first demonstration of Dr. Alexanderscm’s new-size pictiire could ,see it clearly from all parts of a house seating £OOO people. The television camera before which the artists performed their act was in Dr. Alexandcrson’s laboratory a mile from the theatre. Television is combined with radio to give a complete talking picture. RADIO ADVERTISING. I An ielea of the large amount of money spent by American linns on radio advertising was given to members in London recently by Mr E. P. ”BL James, sales promotion manager of the American A at tonal Broadcasting Co. One hour’s broadcasting time on. stations' covering the whole' of the United! States, he said, cost 10,090 dollars' (£2000), and advertisers would spend 1500 to 7000 dollars (0300 to £1400) oil one musical or entertainment programme to nil that time. The Average cost of a programme wa»s 1000 dollars (£200) each half hour, and the average half-hour programme contained a iTttle less than three minutes’ sales talk. INTEREST REVEALED. Radio’s importance. in tho homo was demonstrated definitely when a short breakdown in service .prompted

2(3,000 telephone tails to the .National Broadcasting C.o’s affiliated, station at Spokane, U.S.A. The interesting check was made possible tlnougli a telephone company .survey wiiich showcil in excess .of 23,(H 0 more calls on 'that night than, on the Wednesday previous. According to the telephone company’s check, 1 (5,0;K) calls v.vre to Station K.HQ and thi' remainder went to Spokane newspapers and radio dealers. Spokane has 3.1,709 telephones and apparently two-tiiin’h of the subscribers took orensiem to find nut why they were deprived an hour or radio entertainment. FRENCH RADIO PATENTS. A decision of far-reaching important o to (ho wireless accessories trade in L*\ a me has been given by tbs fourth Chamber of the Appeal Court. It affects sales of £169,000 a- year, *a.i}d concerns (the rival, claims of French anil American firms to the right to exploit in France an invention that was made in both countries almost .simultaneously. The invention is connected with a <antain type of con. French and American wireless engineers discovered that far better results could be obtained with such coils. An, American firm tried to, obtain patents in the United .States on January 10, 1819, and in France on. December 3, 1919. The French company applied for a patent for the same invention m France on March 31, 1919. The question at issue iTien became whether the American firm lin’d the l ight under the Washington Conven- ; tion to assume that the priority of its American patent held good in France on March, by the patent of March 31. do .settle this point the American firm took proceedings against French manufacturers and sellers of the coils in ‘France, Ihe decision was given in favor of the French patentees. RADIO PHOTOGRAPHS. It will probably be a simple natter within tlie next five months to send an ordinary photograph by wireless from Australia to England and vice versa. Tests are now being carried out prop-cj.at(to insta(lli',iig eompSeto equipment for the regular transmission of photographs, and later facsimiles of written and p inted business and other documents. In discussing this latest move to bring the heart of the Empire into

close touch with the outlying Dominions, Air E. T. Fisk said in Sydney that some months ago photographs ol the Prime Minister, Mr SculHn, and of himself were transmitted by wholess to England. They were exoelilent likenesses). Pictures, newspaper cuttings, and documents have been sent by wireless from England to America ; but the first step m tlie first step in tbe Anstralia-Enghmd A u fit ra J ia-En gl a ml transmissions will probably be to send only photographs. FI e is not sure whether, at this stage, it will be possible to transmit written documents o.u a commercial basis. Information on this point is now being awaited!, but lie, Air Fisk, is very hopeful that before long it will be possible to include documentary and other transmissions as well a,s photograph's, and to make it a commercial success for all parties, including the public. “Australia will be able to see, inmost immediately after the events’,” he said, “pictures that reveal the stirring colourful pageantry of British life, in politics, in sport, and in other domains. The English Derby, for instance, will be brought as close to the Sydney public as the Melbourne Cup.”
