WIRELESS MUSIC

ilie Royal. Air Force Communication Squadron, at Kenley, have been doing great tilings with the wireless telephone. They now propose to transmit musical interludes tu the "flippers" on the Lon-don-Paris roii/lp, so that the blase Peace Conference fliers, while soaring 1 somewhore above tho clouds, will be able to listen to the liquid notes of Dame Nellie Melbn or tho roaring orchestration of the Black Diamonds Band. This may sound impossible, but really it is quite nimple. All you have to do is to place a gramophone against tho wireless transmitter and start tho record "revving" in the usual fashion, and the ether is flooded with Hertzian waves of music. Of course you can't hear them—your ear will not respond to ether waves; but there is a wireless receiver in tho machine which receives these Herizian waves and reconverts them into pressure waves which impinge on the diaphragm of the ear. Hence the aerial traveller is beguiled by the strains of tho gramopliono, ten, twenty, or fifty miles away. But look at its possibilities! A wireless telephone transmitter suitably arranged at the Albert Hall would flood London with "inaudible" music. For it to become audible all you would require is a simple wireless telophoue receiver and a small aerial from the top of your house. Then you could sit in comfort at home and listen to a symphony concert or a Covenfc Garden opera. Tho wireless telephone requires no intermediate wiring—the receiver, which only weighs about 101b„ can be carried about like a portable typewriter, its amplification is such that the ear-pieces can' 1m laid on tho tablo and " yet the sounds can bo heard nil over the room; and, moreover, it requires no "oichango" to operate it. This latter point is of enormous advantage. The music "emporiums" need only transmit on different wave-lengths-Albert Hall, say, IiOA metres, Queen's Hall, 650 metres, Covent Garden, 700 metres— and there would bo absolutely no jam. ming. You give a turn to your inductunco handle and immediately you are listening to a concert at the Albert Fall; von give another turn to your inductance, and perhaps switch another condenser into circuit, and you thrill to tho strains of a grand organ recital at Ihe Aeolian Hall: another turn, and "Madame Butterfly" almost persuader, vou-that you are sitting in the stalls at Covent Garden. This is not fiction—il is fact. The telephone receiver is quite a simple thine, and a dry bnlter.v, tiving fit) volts, with three 2-volt, accumulators, would run the whole "liny of tricks."— AV.W.S.,. in the "Daily Mail."
