GOOD RESULTS. WIRELESS TELEGRAPHY.

TESTS BY NAVAL EXPERT. MR. PIKE'S APPARATUS. By Telegraph.— Pret* Association.— Copyright. (Received March 28, 10 a.m.) SYDNEY, This Day. Messages are still being received ov«r a great distance at Mr. Pike's .wireless station. His apparatus was tested by a naval expert with satisfactory results. Mr. Pike is anxious for the Federal Government to put his appliances to a practical test and equip a series of stations. If his overtures to th* Government are rejected he proposes to take the apparatus to America. Mr. J. H. A. Pike, who has done such excellent work in connection with wireless telegraphy, is quite a young man. Hifc instruments, which he has made for himself, are fitted up in the somewhat confined space of bis parents' home, and he speaks somewhat deprecatingly of them when he compares them with the practical appliances in daily use in other parts of the world. But there is a small part of his instruments which is quite his own — which is the outcome oi his own careful study, thought, and perseverance, and to which he has to ascribe the results he has obtained. This is a peculiarly delicate and sensitive "detector," which he is patenting, and which enabled him to hear the Powerful the other day, when nobody else in Australia was equally in "the know." As showing how effective this new "detector" is, Mr. Pike explains that, although his aerial wires are only at a mean height of 50 feet — much lower than, those on ships in the harbour — ho has been able to capture messages which more elaborate instruments have let pass by. He has had messages from ships on the South Australian coast; he has known the whereabouts of the Manuka, 600 miles to the north ; and he has known when the warships in port have been trying to "talk" with mail steamers off the coast. He had heard them when they have not heard each other. When Lord Kitchener was journeying from Melbourne to New Zealand on board H.M.S. Encounter he was in touch with the cruiser each evening until she was 1000 miles away. The German mail steamer Bremen was off the coast at the time, and she was exchanging messages with H.M.S. Powerful in Sydney Harbour, and with the Encounter across the sea, and Mr. Pike knew all they were saying to each other.
