WIRELESS MUSIC.

The Royal Air Force Communication Squadron, at Kenloy. hare been doing great things with the wireless telephone, They now propose to transmit musical interludes to the ‘"flippers” on the Loudon-J’aris route so that the hla.se Reace Conference fliers, while soaring somewhere above the clouds, will be able to listen to the liquid notes of Dame Nellie Melba- or the roaring orchestration of the Black Diamonds Band. This may sound impossible, but really it is quite simple. All you have to do is to place a gramophone against the wireless transmitter and start the record "revving” in the usual fashion, and the ether is flooded with Hertzian waves of music. Of course you can’t hear them—your car will not respond to ether waves; but there is a. wireless receiver in the machine which receives those Hertzian waves and reconverts them into pressure waves which impinge on the diaphragm of the oar. Hence the aerial, traveller is beguiled by the strains of the. gramophone, 10, 20, or GO miles away. But look at its possibilities! A wireless telephone transmitter suitably arranged at the Albert Hull would flood London with ‘‘inaudible” music. For it to become audible all you would require, is a simple wireless telephone receiver and a small aerial from the top of your house. Then you could sit in comfort at homo and listen to a, symphony concert or a Co-vent Garden opera. The wireless telephone requires no intermediate wiring—tho receiver, which only weighs about 101 b., can be carried about like n portable typo-' writer, its amplification is such that the ear-pieces can be laid on tho table and yet the sounds can be heard all over tho room; and, moreover, it requires no “exchange” to operate it. This latter point is of enormous advantage. The music “emporiums” need only transmit on different wave-lengths —•Albert Hall, say, 600'metres, Queen’s Hall, 650 metros, Covent Garden, 700 metres—and there would bo absolutely no jamming. Yon give a turn to your inductance handle and immediately you are listening to a concert at the Albert Hall; you give another turn to your inductance, and perhaps switch another condenser into circuit, and you thrill tr. the. strains of a grand organ recital at tho Aeolian Hall; another turn, and “Madame Butterfly” almost persuades you that you are sitting in tho stalls at Covent Garden. This is not fiction—it is fact. _ Tho telephone receiver is quite, a simple thing, and a dry battery, giving GO volts, with three 2-volt accumulators, would run the whole “box of tricks.”—WAV.S., in the Daily Mail.
