WAYS OF WIRELESS WAVES

The short wireless wayes which are being used so much have recently been found to behave very mysteriously. The wave 80 metres long can, for example, be picked up at any distance up to 50 miles, but is quite often inaudible at points between 50 and 590 miles. But at distances between 500 end 1400 miles the waves can be picked up quite easily, Still shorter waves behave more curiously still. A 15-metre wireless wave

All these and many other quaint vagaries of short wireless waves have just been considered at a special meeting of the Radio Society of Great Britain, and as a result of this meeting it seems quite certain that short waves afte more useful than the miles-long waves hitherto used, at any rate up to distances of a thousand imiles.
