PHOTOGRAPHS SENT FROM SYDNEY TO LONDON

"THIS WONDERFUL MIRACLE”

Transmission of pictures by wireless from Sydney to London was accomplis tied by 2ME (Amalgamated Wireless. Australia, Ltd.), Sydney, for the first time yesterday, and the tests were picked up by Mr. R, Leslie Jones, of Lyall Bay, on his shortwave receiver. . In the early evening several pictures were transmitted to London, including a photograph of Mr. Fisk, managing director of Amalgamated’ Wireless. Ltd. Reception in London was very good indeed. London stated that there were some lines, across the pictures, otherwise reception was excellent The pictures that Sydney recently received from London by wireless were found to be alright as far as the outlines went, but there was hot much detail. The trouble of lines across the pictures was also experienced by Sydney. London had evidently fared much better in regard to reception notwithstanding the 13,000 miles covered. 2ME is anxious for further transmissions, and fur-' ther tests are being carried out to-day. The negatives used yesterday were rather soft and of not very good quality, one being a negative of a picture reproduced from a newspaper—a fact which makes yesterday’s achievement all the more interesting and remarkable.

Several persons in Sydney spoke to London, including a Mr. Pope, who had the pleasure of celebrating his birthday by speaking to friends in London. He thanked Mr. Fisk for allowing him to partake of “this wonderful miracle.’'

Ringing Up London.

As though it were an everyday occurrence, Mr. Wright, another speaker, called up a resident of London by wireless ’phone, and the latter, having gone to the city, his daughter answered as though called locally. The message was of a private nature. The transmission of the last picture took about five minutes, and ail that was heard was an intermittent note similar to one of 1000 cycles. Towards the. finish of the transmission of the picture the note altered somewhat and became a series of dashes clots with a sort of fringe (vibration) at the end of each dash-dot.
