ABOUT WIRELESS

GERMANS' BIG PACIFIC STATIONS,

Hie French Army claims to have tho most powerful wireless telegraphic system iu tho world, and that messages sent through it have reached Australia. It is not known which country now has the most powerful wireless systoni in tho world, but-it is known .that messages • from all the specially highpowered systems can be 6ent right round the world tiid back again past tho dispatching station. It is no secret among wireless operators that, since the. adoption in Australia of the Audion, tho English recoiver and amplifier which improved on the Fleming valve-receiver, messages from Germany have been received in Sydney.and at other wireless stations in the' Commonwealth, just as they have been intercepted in England and elsewhere. It is not within the capacity of the sending instrument to curtail the distance of the projection. Australia receives all messages sent-by high-powered systems of wireless telegraphy, and as the Morse code is In.ternational, except as to Japan, all messages can be read there. Long before America entered tho war Australian operators were frequently able to intercept messages passing between Berlin and New York,

In connection with the above, it is not generally known that Germany had tho most perfect wireless equipments in the Paoifio prior to_ the war, and, what was more, the British authorities knew it without suspecting trouble. The station at Yap Island (now in British hands) had a 60-kilowatt station, capable of talking to Sari Francisco .or Mexico, worked by power generated by two powerful Diesel oil engines. To illustrate the capacity of the Yap station it only has to be mentioned" that tho wireless station on Mount Stake (above Tinnkori Road) is a lj-kilowatt plant, and the big station north of Auckland is a plant.
