OPTIMISTS’ CLUB

RADIO BROADCASTING Mr A. F. O’Donoglmc, who was the lecturer at the Optimists’ luncheon .yesterday, delivered an interesting address on ‘ Some Aspects el Radio Broadcasting,’ dealing chiefly with the features governing the broadcasting of a twoway conversation. Ho detailed the various aspects of the work entailed in preparing for and carrying out the twoway conversation between 4YA, Dunedin, and 2XAF, Schenectady, Now York, when Admiral ilyrd, on his return from the Antarctic, entered into a radio conversation with his principals and friends in America.

The lecturer used diagrams showing the relay lines that wore necessary to link up the New Zealand stations, and tho relay lines that were used throughout tho chain of American broadcast stations.

An interesting description irns given of the reception by '.21'1l K, Sydney, ol 2YA, Wellington, tlio re broadcast of 2ME by 2XAF, and tlio return conversation from 2XAF to tho respective New Zealand stations. In addition to these features it was explained that several stations on tho Continent of Europe and in South America, received tho conversation as broadcast by 2XAF, and rehroadcast it again for tlio benefit of listeners within their limits. In reality, tlio conversation from Dunedin to America and from America to Dunedin was picked up simultaneously by such a wide range of broadcasting stations that there were few corners of the earth in which it was not possible to receive this worldfamed broadcast.
