New radios
The replacement of existing double side-band radios with single side-band sets was required by the International Telecommunications Union. New Zealand, as a member, had to comply, the Post Office Regional Engineer, Mr D.M. McFarlane said yesterday. He was replying to a correspondent of “The Press”, (M. D. Ellery) who asked why the double-band system used, by the Canterbury Mountain Radio Service was no longer acceptable. In the correspondent’s opinion the costs of the charge would be prohibitive for a voluntary organisation. No suitable side-band radios were available on the market at present.
Mr McFarlane said that the change was required to conserve space in the busiest section of the radio spectrum. About twice as many frequencies are available with the use of single side-band equipment than with the double side-band system. He added that completion of the cH'—'ie is not until Jamie- - i 983, and licensee - u by then realise the . economic life of existing equipment.
