Wireless Telephony.

SOME AUCKLAND EXPERIMENTS. VUCKLAND. August 18. Developments that have taken place lately in the realm of wireless have caused some remarkable feats to be accomplished by experiments s. Yueldand one who has been carrying on experiments for many years reports living “picked up” a powerful station at Carnarvon (Wales) using only * single detector circuit. He has also hoard messages from the Aqmtania and Mauretania when crossing the Atlantic •md lie distinguished a call from the Olympic leaving Southampton for New York Dorset stations, France, Germany. South Africa, India China and T ,p al , have been frequently heard by 'this observer, while it is an everyday occurrence to hear the United States and the islands of the Pacific.

Interesting observations on experiences while “listening in” are described 1 Mr G M’B Salt, demonstrator in physics at the Auckland University College who referred to the tact that it was possible to hear high-powered stations at Lyons. Bordeaux, and St. Yssise, in France, only at certain times oh the day. The station at Nation, just outside Berlin, has been heard l.v Air Salt at certain times of the day. and also stations in Rome, Japan, the United States, and other places. All tbe Australian coastal stations wolking ships were hoard with great dis-

tinctness. „ Professor R, Jack of Dunedin, had followed Home boats for seven days out which meant something well over 2000 miles, and had heard a warship’s wireless 4000 miles away.

Dealing with wireless telephony Mr Salt said that Professor Jack had been lieu cl very distinctly at Hamilton, and lie had also been picked up once at Auckland University College. Permission had been given him to use much higher power, in which case ho should he beard distinctly ill all parts of Now Zealand, and possibly also in Australia. A station at Melbourne bad been picked up in New Zealand with the use of only one valve.
